Description

[0002] Flutter is a mobile UI framework open-sourced by Google, which can quickly build high-quality native user interfaces on IOS and Android systems. Therefore, more and more applications are developed using Flutter architecture, but the application developed based on the Flutter framework brings a lot of trouble to testing in the packet capture test phase.

[0003] In the related art, when the code module is initialized, the pre-embedded network proxy IP address and port number are written in the code, and then the network packet capture is realized by configuring the WIFI proxy and combining the Charles software. Although this method can solve the network packet capture problem in the test process, once the APP is packaged and installed, the pre-embedded network proxy IP address and port number are determined, and when the network environment changes and the IP address of the network proxy changes, it is necessary to re-write the code and complete the installation configuration, which is not flexible and cumbersome to operate.

[0044] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0048] Figure 4 This is a schematic diagram of the structure of a computer device provided in an embodiment of this application. Detailed Implementation

[0049] Generally, apps developed using the Flutter framework do not support packet capture. Therefore, some techniques propose hardcoding the pre-installed network proxy IP address and port number in the code during module initialization, and then using a configured Wi-Fi proxy in conjunction with Charles software to capture network packets. While this method solves the network packet capture problem during testing, once the app is packaged and installed, the pre-installed network proxy IP address and port number are fixed. If the network environment changes, causing the network proxy IP address to change, the code needs to be rewritten and the installation and configuration completed, making the process inflexible and cumbersome.

[0050] To address the aforementioned technical problems, the following two solutions are proposed in related technologies:

[0051] One approach is to pre-embed a network proxy management module in the app and activate it via a special method (such as shaking the phone when the app is open). Users can then manually enter the new network proxy IP and port number, and restart the app for the changes to take effect. This eliminates the need for repackaging and adjustments when switching network environments. While this method solves the previous problems of inflexibility and cumbersome operation, it significantly intrudes on the project code and poses certain security risks to the online version. For example, if the network proxy module is removed before deployment, it becomes impossible to locate the problem through packet capture when it occurs online; conversely, if the network proxy module is not removed before deployment, it will lead to online security vulnerabilities.

[0052] Secondly, without modifying the existing app, network proxy packet capture can be achieved by installing a third-party VPN (such as Drony on Android) and performing some configuration. This method is complex and works on Android, but on iOS, due to security restrictions in the Apple App Store, it is not always possible to find VPN software that meets the requirements to achieve network proxy packet capture. This presents problems such as uncertainty on iOS and cumbersome operation with a high learning curve.

[0053] Therefore, the above two solutions introduce new technical drawbacks and are not suitable for adoption. This application proposes a network proxy configuration method. First, in response to a change in the IP address of the proxy server used for packet capture, a preset plugin is called in the application's main function to obtain the first host and first port number of the proxy server configured on the device being captured. The application is developed based on the Flutter framework; the plugin includes a subclass inheriting from the HttpOverrides class. Then, the plugin changes the first host to the second host corresponding to the current IP address and changes the first port number to the corresponding second port number. Finally, the second host and second port number are applied to the global HttpOverrides class to achieve packet capture of the application.

[0054] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0055] Packet capture refers to capturing data during the operation of an app using a computer or dedicated equipment. Apps developed using the Flutter framework are installed on mobile devices such as phones (Android or iOS), tablets (Android or iOS), and computers.

[0056] See Figure 1 The figure is a flowchart of a method for configuring a network proxy provided in an embodiment of this application.

[0057] like Figure 1 As shown, the method includes:

[0058] S101: In response to a change in the IP address of the proxy server used for packet capture, the application's main function calls a preset plugin to obtain the first host and first port number of the proxy server configured on the captured device. The application is developed based on the Flutter framework. The plugin includes a subclass that inherits from the HttpOverrides class.

[0059] The IP address of the proxy server used for packet capture may change for several reasons, including but not limited to the following: First, the device used for packet capture has changed, which in turn leads to a change in the IP address of the proxy server. For example, the device used for packet capture was device A, and now it is device B. Second, the network in which the device used for packet capture is located has changed, which in turn leads to a change in the IP address of the proxy server. For example, the device was originally in network A, and now it is in network B.

[0060] HttpOverrides is a class in the Dart:IO library that helps to override HttpClient using a mock implementation. The implementations in this class default to the actual HttpClient implementation. Therefore, the subclasses described in this embodiment serve the same purpose as the HttpOverrides class, simulating and overriding HttpClient. For ease of description, the "ProxyOverrides class" is used to represent the subclasses.

[0061] As an example, add a static method `createHttpProxy` to the `ProxyOverrides` class. This method returns a `ProxyOverrides` object instance. Inside the `createHttpProxy` method, the proxy server host configured on the current phone is obtained from the native client using `ProxyPlatform.instance.getProxyHost`, and the proxy server port number configured on the current phone is obtained from the native client using `ProxyPlatform.instance.getProxyPort`.

[0062] S102: Change the first host to the second host corresponding to the current IP address through the plugin, and change the first port number to the corresponding second port number.

[0063] As an example, we override the `findProxyFromEnvironment` method of `HttpOverrides`, assuming the current phone is configured with a proxy server host and port number, and assign the `http_proxy` segment in the `environment` parameter to `host:port`. Here, `host` and `port` represent the proxy server and its port number corresponding to the current IP address.

[0064] It is important to note that if the first and second fields are empty, the environment parameter http_proxy or https_proxy field in the findProxyFromEnvironment method must remain unchanged.

[0065] S103: Apply the second host and the second port number to the global HttpOverrides class to enable packet capture of the application.

[0066] As an example, assigning a ProxyOverrides class object to an HttpOverrides.global object enables packet capture of the application.

[0067] By assigning a `ProxyOverrides` class object to an `HttpOverrides.global` object, a global HTTP proxy is set up within the application. The key advantage is that with a single line of code, proxy settings can be applied uniformly throughout the application's lifecycle, eliminating the need to manually configure the proxy for each network request. Furthermore, by overriding the `findProxyFromEnvironment` method, the appropriate proxy server is selected based on the proxy server host and its corresponding port number, and the values ​​of the `http_proxy` and `https_proxy` fields in the environment variables are modified as needed. The crucial aspect of this is the implementation of dynamic proxy server settings, allowing flexible selection of proxy servers based on different network and environmental requirements, and automatic updating of relevant environment variables.

[0068] See Figure 2 The figure is a flowchart of an implementation of the ProxyOverrides proxy class provided in an embodiment of this application.

[0069] like Figure 2 As shown, the implementation includes:

[0070] S201: Create a custom ProxyOverrides class that inherits from HttpOverrides.

[0071] S202: Add a static method createHttpProxy to the custom ProxyOverrides class. This method returns a ProxyOverrides object instance.

[0072] S203: The createHttpProxy method retrieves the host of the proxy server currently configured on the mobile phone from the native side using ProxyPlatform.instance.getProxyHost.

[0073] S204: Obtain the proxy server port number configured on the current mobile phone from the native side via ProxyPlatform.instance.getProxyPort.

[0074] S205: Record the obtained host and port number in the class member variables host and port fields.

[0075] S206: Override the findProxyFromEnvironment method of HttpOverrides.

[0076] S2061: Within the findProxyFromEnvironment method, check if the class member variables host and port are empty. (That is, check if a proxy server host and port number are configured on the current phone.)

[0077] S2062: If the host and port fields are not empty, assign the value 'host:port' to the http_proxy section in the environment parameter;

[0078] In addition, if the host and port fields are empty, the environment parameter will not be modified.

[0079] S207: Call the super.findProxyFromEnvironment method and pass in the environment parameter.

[0080] See Figure 3 The figure is a schematic diagram of the structure of a network proxy configuration device provided in an embodiment of this application.

[0081] like Figure 3 As shown, the device includes: an acquisition module 301, a modification module 302, and an application module 303;

[0082] The acquisition module 301 is used to respond to a change in the IP address of the proxy server used for packet capture. In the main function of the application, a preset plugin is called to obtain the first host and the first port number of the proxy server configured on the device being captured. The application is developed based on the Flutter framework. The plugin includes a subclass that inherits from the HttpOverrides class.

[0083] Modify module 302 to change the first host to the second host corresponding to the current IP address and change the first port number to the corresponding second port number via a plugin;

[0084] Application module 303 is used to apply the second host and the second port number to the global HttpOverrides class in order to capture packets of the application.

[0085] Optionally, module 301 is used specifically for:

[0086] In the main function of the application, call the preset plugin, add the createHttpClient method in the subclass, and use the createHttpClient method to obtain the first host and the first port number of the proxy server configured on the captured device; the createHttpClient method returns an instance object of the subclass.

[0087] Optionally, the device further includes: a judgment module;

[0088] The judgment module is used to record the first host and the first port number of the proxy server in the first and second fields of the class member variables, respectively, and to determine whether the first and second fields are empty through the findProxyFromEnvironment method in the subclass;

[0089] Modify module 302 to change the first host in the findProxyFromEnvironment method to the second host corresponding to the current IP address and change the first port number to the corresponding second port number if the first and second fields are not empty.

[0090] Optionally, module 302 can be modified specifically for:

[0091] If the first and second fields are not empty, the environment parameter http_proxy field or https_proxy field in the findProxyFromEnvironment method will be assigned the value of the second host: second port number.

[0092] Optionally, if the first and second fields are empty, the environment parameter http_proxy or https_proxy in the findProxyFromEnvironment method remains unchanged.

[0093] Optionally, application module 203 is specifically used for:

[0094] Set the global HttpOverrides class as the return value of the createHttpClient method.
