In the first method, a module manager is used to download dependent modules of a target project, and a proxy server converts the download request sent by the module manager using a preset address mapping configuration file, thereby replacing the initial download address in the download request that is not convenient for downloading with a final download address that is convenient for downloading, thereby ensuring the smooth progress of module downloading.

[0032] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0033] In the field of computer front-end technology, after the target project is developed, the project developers need to send the target project to the compiler for compilation, and the target project can be published in the production environment only after the compilation is completed. When the target project is sent from the development end to the compilation end, since the number of dependent modules of the target project is large (up to thousands) and the amount of data is extremely large, the code of the target project can only be sent to the compilation end, and the dependent modules of the target project need the compilation end to download by itself according to the download address provided by the development end. It should be noted that the dependent module of the embodiment of the present invention refers to the modules of all levels on which the target project depends. For example, the target project depends on module a, module a depends on module b, module b depends on module c, module c depends on modules d and e, then a, b, c, d, e are all dependent modules of the target project. In practical applications, the dependent module can be an NPM package managed by a module manager such as NPM (Node Package Manager, a package manager of Node.js, Node.js is a script runtime environment).

[0034] When using NPM to develop a target project, you first need to configure the package.json file, which defines the configuration information of the target project (such as name, version, license and other metadata) and the version range of the dependent modules. When executing the npm install command, NPM can automatically download the required modules according to this file, thereby configuring the operating and development environment required for the target project. After the dependent module is installed, NPM will automatically generate a dependent module version lock file (i.e., package-lock.json file), which records the name, accurate version, download address, verification code of the dependent module recorded in package.json, and the information of the dependent modules at each level of the dependent module (such as name, accurate version, download address, etc.). The download address in this file can be the initial download address to be described below, and the verification code in this file can be a hash value used to verify the integrity and correctness of the dependent module. If you need to install the target project on another terminal device, you need to provide the dependent module version lock file to the terminal device. When executing npm install on the terminal device, if NPM finds that there is a dependency module version lock file in the target project, it will download the dependency module of the target project according to the information in the dependency module version lock file, that is, download the dependency module of the target project according to the initial download address of the dependency module in the dependency module version lock file.

[0035] In the actual application scenario, the compiling end can be used as the above-mentioned other terminal device. When the compiling end downloads the dependent module of the target project according to the dependent module version lock file of the target project, because its network environment is often different from that of the development end, problems often occur in the download process based on the initial download address in the dependent module version lock file, resulting in the inability to download some dependent modules successfully, affecting the compilation of the target project. The present invention can be applied to the above-mentioned scenario to solve the problem of downloading the dependent module of the compiling end. It can be understood that in addition to the above-mentioned scenario, the present invention can also be applied to the scenario of downloading the dependent module when any terminal device installs the target project, and can also be applied to the scenario of downloading the dependent module when developing the target project (in this scenario, the initial download address of the dependent module is determined by NPM according to package.json and the download related information pre-configured by the developer). The following will mainly be described by taking the above-mentioned scenario of downloading the dependent module at the compiling end as an example. It should be pointed out that, in the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0036] The present invention can be applied in an environment where plain text data is transmitted and in an environment where HTTPS protocol is used for data transmission, and is described in detail below through two embodiments. Figure 1 is a schematic diagram of the main steps of the module downloading method in the first embodiment of the present invention, Figure 2Schematic diagram of the implementation architecture of the module download method in the first embodiment of the present invention. Figure 1 , 2 As shown, the specific execution steps of the module download method of this embodiment are as follows:

[0037] Step S101: Start the module manager and the proxy server, and inject a preset address mapping configuration file into the proxy server; wherein the address mapping configuration file includes a mapping relationship between the original address of the module and the expected address.

[0038] In this step, when the client executes the download command, the client reads a predetermined address mapping configuration file, starts the proxy server, and injects the address configuration mapping file into the proxy server. Next, the client starts a module manager such as NPM, and sets the above-mentioned proxy server as an agent for executing the download in the module manager. Among them, the above-mentioned client refers to an application installed on a terminal device (for example, an application for project development or compilation), which generally corresponds to an independent process. Both the proxy server and the module manager can be applications installed on the above-mentioned terminal device (i.e., the terminal device where the client is installed), and the two can correspond to an independent process respectively. In specific applications, the proxy server and the module manager can also respectively adopt independent terminal devices different from the above-mentioned terminal devices. The following is an example of the client, the proxy server and the module manager being installed on the same terminal device.

[0039] The address mapping configuration file can be pre-written by the developer according to the requirements and actual environment, which includes the mapping relationship between the original address and the expected address of the module. Specifically, the original address and the expected address are both download link addresses of the dependent module. The original address is generally an address that is not convenient for downloading due to network isolation or unstable network access on the compilation side. The expected address is an address that is easy for the compilation side to access and can download the same module (i.e., the module pointed to by the corresponding original address). The above-mentioned original address and expected address can both be URLs (Uniform Resource Lo cator), and the URL can have one or more path levels. For example, if a certain original address is www.aaa.org / x / y / z (where x, y, and z all represent strings), it includes the first path level (i.e., domain name) www.aaa.org, the second path level x, the third path level y, and the fourth path level z. The depth of the original address path level is 4 (the depth corresponds to the number of path levels). The previous path level of the original address refers to the first path level or multiple consecutive path levels including the first path level. In this example, the previous path levels of the original address are: www.aaa.org, www.aaa.org / x, www.aaa.org / x / y, www.aaa.org / x / y / z.

[0040] In actual applications, the original address and the expected address can be the link address of the NPM official repository or any mirror repository, or the link address of a non-NPM resource library such as Github (a software project hosting platform). The above mapping relationship in the address mapping configuration file can be shown in the following table.

[0041] Serial number Original address Expected address 1 www.aaa.org / x / y / z www.bbb.org / r / s / z 2 www.ccc.com / l / m / n www.ddd.com / u / v / n 3 www.aaa.org www.bbb.org 4 www.aaa.org / x www.ddd.com / u / v

[0042] In the above table, r, s, l, m, n, u, and v all represent character strings. The mapping relationship in the address mapping configuration file is used to convert the initial download address in some download requests. In this embodiment, if the proxy server determines that the address mapping configuration file contains an original address that matches the initial download address in the download request (i.e., the download address carried in the download request), the final download address is determined according to the expected address corresponding to the original address, thereby realizing the conversion of the initial download address. Among them, the original address matched by the initial download address refers to the original address that is consistent with the previous path level of the initial download address. The process of determining the final download address is specifically: the proxy server determines the original address with the deepest path level (i.e., the largest depth) from the original address matched by the initial download address and uses it as the optimal original address, and uses the expected address corresponding to the optimal original address to replace the previous path level in the initial download address that is consistent with the optimal original address, thereby forming the final download address. It can be understood that if there are other contents in the initial download address in addition to the replaced content, the other contents are retained in the final download address and are in the original position. If the address mapping configuration file contains only one original address that matches the initial download address, the original address can also be considered as the original address with the deepest path level. In addition, if the proxy server determines that the address mapping configuration file does not contain an original address that matches the initial download address, the download request is not converted.

[0043] Taking the address mapping configuration file shown in the above table as an example, if the initial download address is www.ccc.com / l / m / n, the original address it matches is the original address in record 2 (i.e., the record with sequence number 2), which is consistent with the previous path level www.ccc.com / l / m / n (i.e., all the initial download addresses) in the initial download address. At this time, the original address can be determined as the optimal original address, and the expected address www.ddd.com / u / v / n corresponding to the optimal original address is used to replace the previous path level www.ccc.com / l / m / n that is consistent with the optimal original address, thereby forming the final download address www.ddd.com / u / v / n. Since there is no other content in the initial download address except the replaced content, the above retention does not need to be performed.

[0044] If the initial download address is www.aaa.org / x / y / z, the matching original addresses are the original addresses in records 1, 3, and 4. The three original addresses are respectively consistent with the following previous path levels of the initial download address: www.aaa.org / x / y / z, www.aaa.org, and www.aaa.org / x. The path level depths of the three original addresses are 4, 1, and 2, respectively. At this time, the original address with the deepest path level, that is, the original address in record 1, can be determined as the optimal original address, and the expected address www.bbb.org / r / s / z corresponding to the optimal original address is used to replace the previous path level w ww.aaa.org / x / y / z that is consistent with the optimal original address to obtain the final download address www.bbb.org / r / s / z.

[0045] If the initial download address is www.aaa.org / x / t, the matching original addresses are the original addresses in records 3 and 4. The two original addresses are respectively consistent with the following previous path levels of the initial download address: www.aaa.org and www.aaa.org / x. The path level depths of the two original addresses are 1 and 2 respectively. At this time, the original address with the deepest path level, that is, the original address in record 4, can be determined as the optimal original address, and the expected address www.ddd.com / u / v corresponding to the optimal original address can be used to replace the previous path level www.aaa.org / x that is consistent with the optimal original address. At the same time, in addition to the replaced content, there is also unreplaced content / t in the initial download address, so / t needs to be retained in the original position, so that the final download address www.ddd.com / u / v / t can be formed.

[0046] It should be noted that the original address matched by the initial download address is generally required to be exactly the same as one or more previous path levels of the initial download address. For example, taking the address mapping configuration file shown in the above table as an example, if the initial download address is www.fff.org / x / y / z, www.ccc.com or www.ccc.com / l / m / t, it is generally believed that the address mapping configuration file does not contain the original address that matches the three. At this time, the proxy server does not process the download request carrying the above initial download address.

[0047] Step S102: sending a first download request carrying an initial download address of a dependent module of a target project to a proxy server through a module manager.

[0048] In this step, the module manager can determine the initial download address of the dependent module in the form of an NPM package from the dependent module version lock file of the target project, and can determine the initial download address of the non-NPM dependent module through the relevant information of the target project. Afterwards, the module manager can generate a first download request carrying the above initial download address and send it to the proxy server.

[0049] Step S103: When the address mapping configuration file contains an original address that matches the initial download address of the dependent module: the proxy server determines the final download address of the dependent module according to the expected address corresponding to the original address, and generates a second download request carrying the final download address and sends it to the server.

[0050] In this step, the proxy server processes separately according to the difference of the initial download address in the first download request. Specifically, if the proxy server determines that the address mapping configuration file contains the original address that matches the initial download address, the final download address is formed by the aforementioned method and a second download request carrying the final download address is generated and sent to the server; if the proxy server determines that the address mapping configuration file does not contain the original address that matches the initial download address, the first download request is sent directly to the server. Exemplarily, the above-mentioned server can be an NPM official warehouse or any mirror warehouse, or a non-NPM resource library such as Github (a software project hosting platform). After receiving the download request, the server can return the requested dependent module to the proxy server, and the proxy server can send the dependent module to the module manager to complete the download of the dependent module.

[0051] In the module download method of this embodiment, the module manager is used to download the dependent modules of the target project, and the proxy server uses a preset address mapping configuration file to convert the download request sent by the module manager, thereby replacing the initial download address in the download request that is not convenient for downloading with the final download address that is convenient for downloading, thereby ensuring the smooth progress of the module download. This method can provide complete download support for the project dependent modules when the terminal device network access is unstable, while retaining the version information recording function of the dependent modules.

[0052] Figure 3 is a schematic diagram of the main steps of the module downloading method in the second embodiment of the present invention, Figure 4 FIG. 1 is a schematic diagram of the implementation architecture of the module download method in the second embodiment of the present invention. Figure 3 , 4 As shown, the module download method of this embodiment complies with the HTTPS protocol, and the data transmitted in the communication link are all encrypted data. The module download method of this embodiment can perform the following specific steps:

[0053] Step S301: Start the module manager and the proxy server, and inject a preset address mapping configuration file into the proxy server; wherein the address mapping configuration file includes a mapping relationship between an original address and an expected address.

[0054] In this step, when the client executes the download command, the client reads a predetermined address mapping configuration file, starts the proxy server, and injects the address configuration mapping file into the proxy server. Thereafter, the client starts a module manager such as NPM, and sets the above-mentioned proxy server as an agent for executing the download in the module manager. Among them, the above-mentioned client refers to an application installed on the terminal device, which generally corresponds to an independent process. Both the proxy server and the module manager can be applications installed on the above-mentioned terminal device, and the two can correspond to an independent process respectively. The specific content and usage method of the address mapping configuration file are similar to those of the first embodiment, and will not be repeated here. One of the differences between this embodiment and the first embodiment is that the conversion of the initial download address in this embodiment is performed by the simulation server to be described below, and the conversion of the initial download address in the first embodiment is performed by the proxy server.

[0055] Step S302: Start the simulation server through the proxy server, and the module manager sends a first download request to the simulation server through the proxy server; wherein the first download request carries the initial download address of the dependent module of the target project.

[0056] In an embodiment of the present invention, the timing for the proxy server to start the simulation server may be when the proxy server receives a handshake message for the target domain name sent by the module manager. As a preferred solution, when it is necessary to download the dependent modules of the target project, the module manager sends the handshake message to the proxy server; when the proxy server receives the handshake message, it starts the simulation server and generates a simulated digital certificate corresponding to the target domain name and returns it to the module manager via the proxy server.

[0057] In this step, due to the use of HTTPS protocol, the module manager needs to send a handshake message to the server through the proxy server to establish a connection, and then obtain the digital certificate returned by the server for data encryption. The module manager will also verify whether the domain name corresponding to the handshake message (i.e., the target domain name) is the same as the domain name corresponding to the digital certificate returned by the server. If the two are the same, the module manager will determine the above-mentioned server as the correct server and send a download request for the dependent module; if the two are different, the module manager will determine the above-mentioned server as a false server and end the download process. Since it is necessary to perform address conversion on some download requests in this embodiment, the domain name corresponding to the digital certificate of the real server that provides the dependent module download often does not match the domain name corresponding to the above-mentioned handshake message. Therefore, it is necessary to start a simulated server (fake server, also referred to as a fake server) to return a data certificate (hereinafter referred to as a simulated digital certificate) matching the domain name corresponding to the above-mentioned handshake message to the module manager, thereby ensuring the continuous execution of the subsequent dependent module download process. Among them, the simulated server can be started by the proxy server and can correspond to the same process as the proxy server.

[0058] Specifically, in this embodiment, the client pre-installs the root certificate provided by CA (Certificate Authority) in the system, and the root certificate is the public key of CA. When the dependent module of the target project needs to be downloaded, the module manager first sends a handshake message for the target domain name to the proxy server. After receiving the handshake message, the proxy server starts the simulation server. The simulation server uses the corresponding tool to generate a simulated digital certificate corresponding to the target domain name and returns it to the proxy server. The proxy server returns the simulated digital certificate to the module manager.

[0059] Thereafter, the module manager first uses the above-mentioned root certificate to verify the digital certificate returned by the simulation server, that is, to determine whether the above-mentioned root certificate corresponds to the private key used to encrypt the digital certificate (the private key is the private key of the CA). After the verification is passed, the module manager uses the root certificate to decrypt the digital certificate, thereby obtaining the simulation server public key contained in the digital certificate. After that, the module manager generates a random session key, and uses the simulation server public key to encrypt the session key and sends it to the simulation server (via the proxy server). The simulation server uses the private key corresponding to the above-mentioned public key (i.e., the simulation server private key) to decrypt and obtain the session key. At this point, the module manager, the proxy server and the simulation server successfully establish a connection. Thereafter, the module manager can determine the initial download address of the dependent module in the form of an NPM package from the dependent module version lock file of the target project, and can determine the initial download address of the non-NPM dependent module through the relevant information of the target project. Next, the module manager generates a first download request carrying the above-mentioned initial download address, and uses the above-mentioned session key to encrypt the first download request, and finally sends the encrypted first download request to the simulation server via the proxy server. It can be understood that the domain name in the above-mentioned initial download address is the target domain name.

[0060] Step S303: Use the simulation server to determine whether the address mapping configuration file contains an original address that matches the initial download address of the dependent module: If so, the simulation server determines the final download address of the dependent module based on the expected address corresponding to the original address, and generates a second download request carrying the final download address and sends it to the server.

[0061] In this step, the simulation server uses the session key it has to decrypt the first download request, and processes it according to the differences in the first download request. Specifically, if the simulation server determines that the address mapping configuration file (the simulation server can read the address mapping configuration file from the proxy server) contains an original address that matches the initial download address, the method described in the first embodiment is used to form the final download address and generate a second download request carrying the final download address and send it to the server; if the simulation server determines that the address mapping configuration file does not contain an original address that matches the initial download address, the first download request is sent directly to the server. It can be understood that both the first download request and the second download request need to be encrypted when transmitted to the server.

[0062] In this embodiment, the server corresponding to the first download request is the initial server, that is, the server pointed to by the initial download address, and the server corresponding to the second download request is the expected server, that is, the server associated with the expected address. After receiving the download request, the server decrypts the download request and returns a response message including the module to be downloaded to the simulation server. After receiving the response message, the simulation server encrypts the response message using the session key it owns, and sends the encrypted response message to the module manager through the proxy server. After receiving the encrypted response message, the module manager decrypts it using the session key it owns, thereby obtaining the module to be downloaded.

[0063] Through the above steps, the present invention realizes a dependent module download scheme based on the HTTPS protocol, which can ensure the reliability of data transmission while using the final download address to obtain the dependent module. In the module download method of this embodiment, in addition to starting the module manager and the proxy server, the simulation server is further started to return a simulated digital certificate corresponding to the target domain name to the module manager. The public key in the simulated digital certificate can be used to encrypt the session key sent by the module manager to the simulation server; after receiving the download request, the simulation server can decrypt the download request and convert the download request using the address mapping configuration file, thereby replacing the initial download address in the download request that is not convenient for downloading with the final download address that is convenient for downloading, thereby ensuring the smooth download of the module. This method can provide complete download support for the project dependent module when the network access of the terminal device is unstable, while retaining the version information recording function of the dependent module.

[0072] In an embodiment of the present invention, the device may further include a trust establishing unit, which is used to: before the module manager sends the first download request: use the module manager to send a handshake message for the target domain name to the proxy server, use the simulation server to generate a simulation digital certificate corresponding to the target domain name and return it to the module manager; after the simulation digital certificate is verified by using a pre-installed root certificate, the module manager sends a preset session key to the simulation server via the proxy server; the session key is encrypted using the public key contained in the simulation digital certificate during the sending process; the simulation server uses the private key corresponding to the public key to decrypt the encrypted session key; wherein, the first download request is encrypted using the session key in the process of being sent from the module manager to the simulation server, and the simulation server uses the session key to decrypt the encrypted first download request, and the domain name in the initial download address of the dependent module carried in the first download request is the target domain name.

[0073] As a preferred solution, the original address matched by the initial download address of the dependent module is consistent with the previous path level of the initial download address. The address conversion unit is further used to: determine the original address with the deepest path level among the original addresses matched by the initial download address of the dependent module as the optimal original address, and use the expected address corresponding to the optimal original address to replace the previous path level consistent with the optimal original address in the initial download address to form the final download address; when the original address matched by the initial download address of the dependent module is not contained in the address mapping configuration file, the simulation server sends the first download request to the server.

In the first device, the module manager is used to download the dependent module of the target project, and the proxy server uses the preset address mapping configuration file to convert the download request sent by the module manager, thereby replacing the initial download address in the download request that is not convenient for downloading with the final download address that is convenient for downloading, thereby ensuring the smooth progress of the module download. In the second device, in addition to starting the module manager and the proxy server, the simulation server is further started to return the simulation digital certificate corresponding to the target domain name to the module manager, and the public key in the simulation digital certificate can be used to encrypt the session key sent by the module manager to the simulation server; after receiving the download request, the simulation server can decrypt the download request and convert the download request using the address mapping configuration file, thereby replacing the initial download address in the download request that is not convenient for downloading with the final download address that is convenient for downloading, thereby ensuring the smooth download of the module.
