xposed hookokhttp

Xposed框架可以通过hook OkHttp的方式来实现对网络请求的拦截和修改。下面是一个简单的示例代码：

public class OkHttpHook implements IXposedHookLoadPackage {
    private static final String TARGET_PACKAGE = "com.example.app";
    private static final String TARGET_CLASS = "com.example.app.MyOkHttpClient";

    @Override
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
        if (!lpparam.packageName.equals(TARGET_PACKAGE)) {
            return;
        }

        final Class<?> targetClass = findClass(TARGET_CLASS, lpparam.classLoader);

        XposedHelpers.findAndHookMethod(targetClass, "getOkHttpClient", new XC_MethodReplacement() {
            @Override
            protected Object replaceHookedMethod(MethodHookParam param) throws Throwable {
                OkHttpClient.Builder builder = new OkHttpClient.Builder();
                // 添加自定义的拦截器
                builder.addInterceptor(new MyInterceptor());
                return builder.build();
            }
        });
    }

    private static class MyInterceptor implements Interceptor {
        @Override
        public Response intercept(Chain chain) throws IOException {
            // 在这里可以对请求进行拦截和修改
            Request request = chain.request();
            Response response = chain.proceed(request);
            return response;
        }
    }
}

这个示例代码会在目标应用的`MyOkHttpClient`类中的`getOkHttpClient`方法被调用时，替换返回的`OkHttpClient`实例，添加一个自定义的拦截器`MyInterceptor`。在`MyInterceptor`中可以对请求进行拦截和修改。
