[0017] The file path corresponding to the access address that matches the file name of the target transmission file is confirmed as the file path of the target transmission file.
[0018] In this embodiment, by storing the file path of each transmission file and the access address of each transmission file in a preset mapping table, after the file name of the target transmission file matches the access address of each transmission file in the preset mapping table, the file path corresponding to the access address matching the file name of the target transmission file can be quickly found, and then the file path of the target transmission file can be determined.
[0019] According to the above aspects and any possible implementation, there is further provided an implementation, wherein the file access request also carries the current identity information of the request sender and the current request code;

[0024] This embodiment can increase the security of file transmission and ensure that there is no risk of file leakage.
[0025] According to the above aspects and any possible implementation method, an implementation method is further provided to display the result of whether the current identity information matches the pre-stored legal identity information and the result of whether the current request code matches the preset request code.
[0026] In this embodiment, by displaying the result of whether the current identity information matches the pre-stored legal identity information and whether the current request code matches the preset request code, the user on the server side can intuitively see whether the target transfer file can be sent to the sender.
[0027] According to the above aspects and any possible implementation, an implementation is further provided.
[0028] The sender includes multiple senders; the file access request includes multiple file access requests;
[0029] The step of acquiring the target transfer file from the file path of the target transfer file and transmitting the target transfer file to the sender of the file access request comprises:
[0030] Obtain the sender's current identity information and current request code carried in each file access request;
[0031] Determining whether the current identity information of each sender matches the pre-stored legal identity information;
[0032] Selecting a sender that matches the pre-stored legal identity information from among the senders as a candidate sender;
[0033] Confirm the request priority corresponding to the current request code of each sender;
[0034] Selecting a sender with the highest request priority from the candidate senders as a target sender;
[0035] The target transmission file is read from the file path of the target transmission file and then transmitted to the target sender.
[0036] This embodiment can ensure that the target transmission file is sent only to the legitimate sender with the highest request priority, and the confirmation of identity information and request code increases the security of file transmission and ensures that there is no risk of file leakage.

[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0057] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0058] Figure 1 The flowchart of the file transmission method 100 according to the embodiment of the present disclosure is shown. The execution subject of the method 100 may be a server, and the method 100 may include:
[0059] Step 110, receiving a file access request, wherein the file access request carries a target access address of a target transfer file;
[0060] The file access request may be a file access request based on the Https protocol sent by the sender to the target access address;
[0061] Https protocol is Hypertext Transfer Protocol.
[0062] The file access request based on the Https protocol is a file access request generated using the Https protocol, which is a file access request based on a browser. The sender can be any device among multiple devices that need to transfer files (such as Figure 2 Any device in the multiple devices), and the server is other devices in the multiple devices except the any device (such as Figure 2 For example: the sender is Figure 2 If the server is a device using the Android system, then the server can be a device using the Windows operating system, or the server can be a device using the IOS operating system.
[0063] The sender may be a client, requesting the target transfer file as a client. The target access address may be provided to the sender in advance by the server. Of course, since the target access address may be generated by the network address of the server, the port number of the port for transferring files on the server, and the file name of the target transfer file, if the sender knows the generation rule of the access address, the target access address may also be automatically generated based on this information.
[0064] Since the target access address is generated in combination with the file name of the target transmission file, the file name of the target transmission file can be obtained based on the target access address.
[0065] Step 120, based on the target access address, obtaining the file name of the target transmission file;
[0066] Specifically, the target access address carried in the file access request may be parsed, and then the file name of the target transmission file that the sender needs to access may be obtained;
[0067] During parsing, the target access address can be parsed according to the starting position and byte length of the file name in the access address to obtain the file name of the target transfer file.
[0068] The file access request may include not only the target access address, but also the sender's intention (such as downloading, uploading), the sender's current identity information and the current request code. Of course, the sender's intention can be represented by a number or symbol, for example: the number 1 represents the sender's intention to download, the number 0 represents the sender's intention to upload, or the symbol / represents the sender's intention to download, and the symbol , represents the sender's intention to upload; this is not limited in the present disclosure. The target access address may include not only the file name of the target transfer file, but also the network address of the server where the target transfer file is located and the file transfer port number of the target transfer file, that is, the target access address may be composed of these three items of information.
[0069] Step 130, matching the file name of the target transmission file with the pre-stored access address of each transmission file to confirm the file path of the target transmission file; wherein the access address of each transmission file includes the file name of each transmission file;
[0070] The file path of each transmission file and the access address of each transmission file may be stored in correspondence in advance, so that after confirming the access address matching the target transmission file, the file path of the target transmission file may be confirmed.
[0071] Each transmitted file can be any video, document, audio, etc., and there is no restriction on the platform and transmission protocol used. For example: the sender can be a platform using the Android operating system or the sender can be a platform using the IOS system (mobile operating system) or the sender can be a platform using the MAC system or the sender can be a platform using the Windows system.
[0072] For another example: the sender can use the Http protocol to send the file access request, or the sender can use the FTP (File Transfer Protocol) protocol to send the file access request, or the sender can use the TCP / IP protocol to send the file access request. Of course, it is preferred that the sender uses the Http protocol to send the file access request, that is, the sender and the receiver can transfer files through the cross-platform feature of the web browser, which means that the present disclosure can use the browser to easily implement file transfer between different types of devices.
[0073] Step 140: Obtain the target transfer file from the file path of the target transfer file and transmit it to the sender of the file access request.
[0074] When a file access request is received, the file name of the target transfer file can be obtained based on the target access address, and then the file name of the target transfer file can be matched with the access addresses of each transfer file stored in advance to confirm the file path of the target transfer file. The target transfer file can then be obtained from the file path of the target transfer file and then transmitted to the sender of the file access request. In this way, different devices can realize file transfer conveniently and quickly, avoiding the need to install a unified communication tool between different devices or introduce a separate device as a transit to realize file transfer, thereby improving the portability of file transfer, and since no transit device is required, the security and confidentiality of file transfer are improved.
[0075] In some embodiments, before matching the file name of the target transmission file with the pre-stored access address of each transmission file, the method further includes:
[0076] Obtain the network address and file transfer port number of the server where each transfer file is located;
[0077] The network address is the IP (Internet Protocol Address) address.
[0078] The file transfer port number is the port number of the port for transferring files. A file transfer port number can be arbitrarily specified on each server.
[0079] The file name of each transmission file, the network address of the server where each transmission file is located, and the file transmission port number are combined to obtain the access address of each transmission file.
[0080] After obtaining the network address and file transfer port number of the server where each transfer file is located, the file name of each transfer file, the network address and file transfer port number of the server where each transfer file is located can be automatically combined to obtain the access address of each transfer file. Compared with directly providing the file path of each file on the server to the sender, this can avoid the leakage of the real storage address of each file, thereby further improving the security of file transmission.
[0081] The combination can be as follows:
[0082] The access address of each transferred file = the network address of the server where each transferred file is located + the file transfer port number + the file name of each transferred file. For example, if the network address of device A is 192.168.1.1, the file transfer port number is 8080, and the file name of the target transferred file is sample.txt, then the access address of the target transferred file can be: https: / / 192.168.1.1:8080 / download / sample.txt, but its actual file path on the server can be / sdcard / shared / sample.txt->sample.txt.
[0083] In some embodiments, matching the file name of the target transmission file with the pre-stored access addresses of each transmission file to confirm the file path of the target transmission file includes:
[0084] The file paths of the transmission files and the access addresses of the transmission files are stored in a preset mapping table in correspondence;
[0085] Matching the file name of the target transmission file with the access address of each transmission file in the preset mapping table to find the file path corresponding to the access address matching the file name of the target transmission file;
[0086] Since the access address of each transmission file is generated by the file name of each transmission file, the file path matching the file name of the target transmission file can be found by matching the file name of the target transmission file with the access address of each transmission file.
[0087] The file path corresponding to the access address that matches the file name of the target transmission file is confirmed as the file path of the target transmission file.
[0088] By storing the file paths of each transmission file and the access addresses of each transmission file in a preset mapping table, the file name of the target transmission file is matched with the access addresses of each transmission file in the preset mapping table, the file path corresponding to the access address matching the file name of the target transmission file can be found, and then the file path of the target transmission file can be determined.
[0089] In some embodiments, the file access request also carries the current identity information of the request sender and the current request code;
[0090] The current identity information may be a CA (Certificate Authority) certificate, a public key, and the like.
[0091] The acquiring the target transmission file from the file path of the target transmission file and transmitting it to the sender includes:
[0092] Determining whether the current identity information matches the pre-stored legal identity information;
[0093] If they match, determining whether the current request code matches the preset request code;
[0094] The current request code can be a randomly generated string.
[0095] If the current request code matches the preset request code, the target transmission file is read from the file path of the target transmission file and then transmitted to the sender.
[0096] If the current identity information matches the pre-stored legal identity information, it means that the sender is a legal sender and has preliminary access qualifications. Furthermore, if the current request code matches the preset request code, it means that the sender is the sender for whom the server needs to provide file services. Therefore, the target transfer file can be automatically read from the file path of the target transfer file, and then the target transfer file can be automatically transferred to the sender. After receiving the data stream from the server, the sender automatically enters the file writing process. By default, the target transfer file is written to a specific directory (such as / sdcard / shared), and the target file name is consistent with the file name on the server.
[0097] In addition, the confirmation of identity information and request code increases the security of file transmission and ensures that there is no risk of file leakage.
[0098] In some embodiments, the result of whether the current identity information matches the pre-stored legal identity information and the result of whether the current request code matches the preset request code are displayed.
[0099] By displaying the result of whether the current identity information matches the pre-stored legal identity information and whether the current request code matches the preset request code, the user on the server side can intuitively see whether the target transfer file can be sent to the sender.
[0100] In some embodiments, the sender includes multiple senders; the file access request includes multiple senders;
[0101] The acquiring the target transmission file from the file path of the target transmission file and transmitting it to the sender includes:
[0102] Obtain the sender's current identity information and current request code carried in each file access request;
[0103] Determining whether the current identity information of each sender matches the pre-stored legal identity information;
[0104] Selecting a sender that matches the pre-stored legal identity information from among the senders as a candidate sender;
[0105] Confirm the request priority corresponding to the current request code of each sender;
[0106] Selecting a sender with the highest request priority from the candidate senders as a target sender;
[0107] The target transmission file is read from the file path of the target transmission file and then transmitted to the target sender.
[0108] There can be multiple senders, and accordingly, the file access request can also include multiple ones. In this way, it can be determined whether the current identity information of each sender matches the pre-stored legal identity information, and then the sender matching the pre-stored legal identity information is selected from each sender as a candidate sender, that is, a legal sender is selected from multiple senders, and then the request priority corresponding to the current request code of each sender is confirmed, and then the sender with the highest request priority is selected from the candidate senders as the target sender. In this way, the target transfer file can be read from the file path of the target transfer file and then transmitted to the target sender. This ensures that the target transfer file is only sent to a legal sender with the highest request priority, and the confirmation of the identity information and the request code increases the security of file transmission and ensures that there is no risk of file leakage.
[0109] In some embodiments, the method further comprises:
[0110] Tracking the current transfer progress of the target transfer file;
[0111] The current transmission progress of the target transmission file is displayed.
[0112] By automatically displaying the current transmission progress of the target transmission file, the user at the server side can intuitively see the transmission progress of the target transmission file.
[0113] The following will be combined Figure 2 The technical solution of the present disclosure is further described in detail:
[0114] With device A (such as Figure 2 Windows device) to device B (such as Figure 2 Take sending the specified file sample.txt to an Android device in the example, connect devices A and B to the same network, A acts as the server (assuming the IP is 192.168.1.1), and B acts as the sender (assuming the IP is 192.168.1.2).
[0115] When creating the server, specify the port information (such as 8080), and the file path to be transferred (such as / sdcard / shared / sample.txt->sample.txt) and the access address of the file path (such as https: / / 192.168.1.1:8080 / download / sample.txt ) are added to the mapping table accordingly.
[0116] B can only access the specified address https: / / 192.168.1.1:8080 / download / sample.txt with his own identity information and request code. At the same time, a pop-up window can be displayed to show the request code used for this request. Specifically: when the server receives the request for the URL, it will parse out the key information download and sample.txt, and get the specific file path of the corresponding file from the mapping table, and get the sender's identity information and request code from the request. At the same time, a pop-up window will prompt whether the request code and identity are acceptable. If confirmed, the server can enter the file stream sending process, and the current file sending progress can be displayed on the UI.
[0117] After receiving the data stream from the server, the sender automatically enters the process of writing files. By default, the file is written to a specific directory (such as / sdcard / shared), and the file name is consistent with that on the server.
[0118] Similarly, B can also be used as the server (i.e., Http server), and A accesses the specified address https: / / 192.168.1.2:8080 / upload / sample.txt. B receives the request and writes the data stream to the specified file / sdcard / shared / sample.txt after passing the identity authentication.
[0119] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present disclosure.
[0120] The above is an introduction to the method embodiment. The following is a further explanation of the scheme disclosed in the present invention through an apparatus embodiment.
