这篇博客介绍了如何在Android应用程序中实现网络请求的全局拦截，通过自定义Interceptor在每个请求中添加统一的请求头。具体做法是在Application类中获取SharedPreferences，然后在Interceptor中读取登录信息，设置到请求头。

//App

public class app extends Application {
private static Context context;

@Override
public void onCreate() {
    super.onCreate();
   context=this;
    Fresco.initialize(this, ImagePipelineConfig.newBuilder(app.this)
            .setMainDiskCacheConfig(
                    DiskCacheConfig.newBuilder(this)
                            .setMaxCacheSize(10 * 1024 * 1024)
                            .setBaseDirectoryPath(new File(Environment.getExternalStorageDirectory().getAbsolutePath()))
                            .build()

            )
            .build());
}

public static Context getContentInstace() {
    return context;
}

}

//工具类

.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
SharedPreferences login = app.getContentInstace().getSharedPreferences(“login”, Context.MODE_PRIVATE);

                   Request request = chain.request();
                   Request.Builder headers = request.newBuilder()
                           .addHeader("userId", login.getString("userId", ""))
                           .addHeader("sessionId", login.getString("sessionId", ""));
                   Request request1 = headers.build();
                   return chain.proceed(request1);
               }
           }).cache(cache)
           .build();
