[0002] In front-end development projects, developers will generate or use different domain names according to different environments or configurations to obtain static resource URLs (uniform resource locators). During development, developers will first develop the project locally, then use the build tool to package the front-end source code to generate code, and finally deploy the front-end static resource files corresponding to the code to the server for loading and access.

[0003] At present, in front-end development projects, static resource URLs are usually configured to use different domain names in different environments or to be deployed on different servers. Among them, the traditional static resource URL configuration method is usually fixed, that is, the developer manually configures the static resource URL, that is, configures the domain name in the static resource URL. This has the following shortcomings: (1) It is difficult to dynamically select the optimal CDN node (that is, select the optimal domain name) at runtime, which will result in slower resource loading speed and thus reduce operating performance; (2) Manual configuration is not only costly, but also reduces configuration efficiency. Therefore, based on the above shortcomings, how to provide a dynamic replacement method for static resource URLs that can select the optimal CDN node during configuration and has low cost and high efficiency has become a problem to be solved urgently.

[0056] Example:

[0057] See also Figure 1As shown, the method for dynamically replacing the static resource URL provided in this embodiment creates a Proxy object for the static resource URL through an innovative JavaScript proxy mechanism, and then uses the get trap in the Proxy object to determine the optimal CDN resource domain name from the candidate static resource library after receiving the CDN resource access request, and then, based on the optimal CDN resource domain name, the optimal static resource URL can be generated; finally, the aforementioned optimal static resource URL is used to replace the original static resource URL, and the dynamic replacement of the original static resource URL can be completed; thus, through the above design, compared with the traditional technology, the method does not require manual intervention, which not only reduces the cost but also improves the configuration efficiency. At the same time, the present invention also realizes the dynamic selection of the optimal CDN node, which can ensure the loading speed of resources and thus improve the operation performance; therefore, the method is very suitable for large-scale application and promotion; wherein, for example, the method can be, but not limited to, run on the URL configuration end side, and optionally, the URL configuration end can be, but not limited to, a personal computer (PC). It can be understood that the aforementioned execution subject does not constitute a limitation on the embodiment of the present application, and accordingly, the operation steps of the method can be, but not limited to, as shown in the following steps S1 to S5.

[0058] S1. Obtain a specified static resource URL and construct a Proxy object of the specified static resource URL. In this embodiment, a proxy object library may be pre-set, in which Proxy objects corresponding to different static resource URLs are stored. Therefore, after obtaining the aforementioned specified static resource URL, the corresponding Proxy object may be obtained by matching it in the proxy object library. The Proxy object is created by using Proxy (a built-in object in JavaScript that allows interception and customization of operations on an object), and then some behaviors of the specified object may be customized by operating the proxy object. Therefore, in this embodiment, the Proxy object is used to dynamically replace the static resource URL, and in the replacement process, the Proxy object is used to select the optimal CDN node, that is, the optimal CDN domain name (which refers to the domain name of the acceleration service of the Content Delivery Network (CDN)) to ensure that the replaced URL can achieve the optimal loading speed.

[0059] Optionally, the Proxy object is taken as a two-layer object, that is, it includes a first proxy object and a second proxy object, wherein the attribute value of the first proxy object is used to return the second proxy object in the Proxy proxy object, and the second proxy object is used to call an implicit conversion function; based on this, the first proxy object is a value object, which is used to deconstruct the entire Proxy proxy object, and its attribute value represents a Proxy object (i.e., the second proxy object) that can be calculated using privacy transformation. Therefore, using this attribute value, the aforementioned second proxy object can be returned; finally, the second proxy object can be used to select the optimal CDN node and generate a complete optimal static resource URL for replacing the aforementioned specified static resource URL.

[0060] The dynamic selection process of the optimal CDN node (ie, the optimal CDN resource domain name described below) may be, but is not limited to, as shown in the following steps S2 and S3.

[0061] S2. Access the Proxy object to obtain a get trap of the Proxy object. In a specific implementation, the get trap is an attribute of the Proxy object, which is a function used to intercept access requests to the attributes of the proxy object. Therefore, this implementation responds to the dynamic selection operation of the optimal CDN resource domain name based on the get trap (the selection process is described below). At the same time, it has been explained above that the Proxy object is a two-layer object. Therefore, it is necessary to access two layers of objects to obtain the get trap. The process can be but is not limited to the following steps S21 to S24.

[0062] S21. Access the properties of the first proxy object to obtain the property values ​​of the first proxy object; in this embodiment, the first proxy object is actually also a Proxy object, which is provided with multiple properties (such as name, etc.), and each property corresponds to an attribute value; therefore, this embodiment returns the second-layer proxy object by accessing the attribute values ​​in the constructed Proxy object, so that the returned second-layer proxy object (i.e., the second proxy object) can be used to obtain the get trap later; of course, in this embodiment, the properties of the aforementioned first proxy object are set to an object return string, and its attribute value is used to return the second proxy object.

[0063] In this way, after obtaining the attribute value of the first proxy object, the second proxy object can be returned from the Proxy object based on the attribute value, and the process can be but not limited to the following step S22.

[0064] S22. According to the attribute value, access the Proxy object to return the second proxy object from the Proxy object; in this embodiment, after obtaining the second proxy object, the attributes of the second proxy object can be obtained so as to obtain the aforementioned get trap from the attributes of the second proxy object; wherein, the specific acquisition process of the get trap can be but is not limited to as shown in the following steps S23 and S24.

[0065] S23. Access the properties of the second proxy object to determine the proxy parameters from the properties of the second proxy object; in this embodiment, the second proxy object can be regarded as the proxied object, and its properties are configured as multiple proxy parameters, including Handler parameters and Target parameters, etc., wherein the Target parameter represents the object to be intercepted, and the handler parameter is also an object used to customize the interception behavior; therefore, the aforementioned proxy parameter corresponds to a get method, and the get method is used to intercept access requests to the object properties; in this way, the aforementioned get trap can be determined based on the aforementioned proxy parameters, and the process is shown in the following step S24.

[0066] S24. Based on the proxy parameters, obtain a get trap of the Proxy proxy object.

[0067] In this way, through the aforementioned steps S21 to S24, the get trap of the Proxy proxy object can be obtained, and then, access interception can be performed based on the get trap. That is, in this embodiment, it is equivalent to using the get method of the Proxy proxy object to intercept the access request, and use this as a trigger condition for the dynamic selection of the optimal CDN resource domain name, and then after intercepting the access request, enter the dynamic selection process of the optimal CDN resource domain name.

[0068] The dynamic selection process of the optimal CDN resource domain name may be, but is not limited to, as shown in the following step S3.

[0069] S3. Execute the get trap to intercept CDN resource access requests based on the get trap, and after intercepting the CDN resource access requests, use the alternative static resource library to determine the optimal CDN resource domain name; in the specific implementation, the alternative static resource library stores a number of alternative static resource URLs, and this embodiment uses a small fragment network request method to determine the optimal CDN resource domain name from a number of alternative static resource URLs, and the process can be but is not limited to the following steps S31 to S35.

[0070] S31. Obtain designated running resources; in specific applications, for example, the designated running resources may be, but are not limited to, images or applets, that is, use the URLs of the alternative static resources in the alternative static resource library to load the aforementioned images or applets; then, determine the optimal CDN resource domain name based on the loading response time; optionally, the aforementioned process of determining the optimal CDN resource domain name based on the loading response time may be, but is not limited to, as shown in the following steps S32 to S35.

[0071] S32. Utilize each candidate static resource URL to load the specified running resource to obtain the loading response time of each candidate static resource URL; in this embodiment, after obtaining the loading response time of each candidate static resource URL to load the aforementioned specified running resource, the optimal CDN resource domain name can be determined based on the shortest loading response time, and the process can be but not limited to as shown in the following steps S33 and S34.

[0072] S33. Filter out the shortest loading response time from each loading response time; in specific implementation, the shorter the loading response time, the faster the loading speed of the specified running resource is, and the higher its running performance is; therefore, this embodiment filters out the shortest loading response time, and determines the optimal CDN resource domain name based on its corresponding alternative static resource URL, and the process is shown in the following steps S34 and S35.

[0073] S34. The alternative static resource URL corresponding to the shortest loading response time is used as the optimal alternative static resource URL.

[0074] S35. According to the optimal candidate static resource URL, the optimal CDN resource domain name is obtained; in this embodiment, the domain name of the optimal candidate static resource URL can be used as the optimal CDN resource domain name by way of example but is not limited thereto.

[0075] In this way, through the aforementioned steps S31 to S35, the optimal CDN resource domain name can be determined from the alternative static resource library; then, based on the optimal CDN resource domain name and using the Proxy proxy object, the optimal static resource URL can be generated; wherein, the generation process of the optimal static resource URL can be but is not limited to as shown in the following step S4.

[0076] S4. Generate an optimal static resource URL based on the Proxy object and the optimal CDN resource domain name. In this embodiment, for example, but not limited to, first obtain the resource access path; then, use the Proxy object and generate the optimal static resource URL based on the resource access path and the optimal CDN resource domain name; wherein, the resource access path is a string data, which can be pre-set in the URL configuration terminal and can be read when used.

[0077] At the same time, since the optimal CDN resource domain name is obtained by using the get method (i.e., get trap) in the attributes of the second proxy object, the determined optimal CDN resource domain name is actually a temporary Proxy object, and its data type is different from the data type of the resource access path; at the same time, when constructing the Proxy proxy object, this embodiment constructs a second proxy object for calling the implicit conversion function (the implicit conversion function is used to convert the data type of the aforementioned temporary Proxy object to obtain an optimal resource domain name string of the same data type as the resource access path). In this way, it is necessary to use the second proxy object to perform data type conversion of the optimal CDN resource domain name, and then, combined with the aforementioned pre-set resource access path, the optimal static resource URL can be generated.

[0078] Optionally, the aforementioned data type conversion process is: using the Proxy proxy object to convert the optimal CDN resource domain name into a string to obtain the optimal resource domain name string; specifically, using the second proxy object in the Proxy proxy object to call the implicit conversion function; then, based on the implicit conversion function, the optimal CDN resource domain name is subjected to string conversion processing to obtain the optimal resource domain name string after the string conversion processing; in this embodiment, the implicit conversion function is a commonly used function for data type conversion, and its principle will not be repeated.

[0079] In this way, after obtaining the optimal resource domain name string, the optimal resource domain name string and the resource access path are concatenated to obtain the optimal static resource URL.

[0080] Based on the aforementioned step S4, an optimal static resource URL can be generated, and then, the optimal static resource URL can be used to replace the aforementioned specified static resource URL. The process can be but is not limited to as shown in the following step S5.

[0081] S5. Use the optimal static resource URL to replace the specified static resource URL, so as to complete the dynamic replacement of the specified static resource URL after the replacement process; in this embodiment, it is equivalent to replacing the specified static resource URL with the aforementioned optimal static resource URL, thereby performing resource loading based on the optimal static resource URL.

[0082] Therefore, through the dynamic replacement method of static resource URL described in detail in the aforementioned steps S1 to S5, the present invention creates a Proxy object for the static resource URL through an innovative JavaScript proxy mechanism, and then uses the get trap in the Proxy object to determine the optimal CDN resource domain name from the alternative static resource library after receiving the CDN resource access request, and then, based on the optimal CDN resource domain name, the optimal static resource URL can be generated; finally, the aforementioned optimal static resource URL is used to replace the original static resource URL, and the dynamic replacement of the original static resource URL can be completed; thus, through the above design, compared with the traditional technology, the present method does not require manual intervention, which not only reduces the cost but also improves the configuration efficiency. At the same time, the present invention also realizes the dynamic selection of the optimal CDN node, which can ensure the loading speed of resources and thus improve the operation performance; therefore, the present method is very suitable for large-scale application and promotion.
