OkHttp3的簡單使用：

在Application中初始化OkHttp3

public class App extends Application {
    public static OkHttpClient okHttpClient;
@Override
public void onCreate() {
        super.onCreate();
ImageLoaderConfiguration configuration=new ImageLoaderConfiguration.Builder(this)
                        .build();
 
ImageLoader.getInstance().init(configuration);
okHttpClient = new OkHttpClient();
okHttpClient = okHttpClient.newBuilder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .readTimeout(10, TimeUnit.SECONDS)
                .addInterceptor(new MyLogInterceptor())
                .build();
 
}
    //攔截器,可以修改header,可以通過攔截器列印日誌
public class MyLogInterceptor implements Interceptor {
        @Override
public Response intercept(Chain chain) throws IOException {

            Request request = chain.request().newBuilder()
                    .header("shenfen", "chinesse")
                    .build();
 
HttpUrl url = request.url();
String httpUrl = url.url().toString();
Log.e("TAG", "============" + httpUrl);
Response response = chain.proceed(request);
            int code = response.code();
Log.e("TAG", "============response.code() == " + code);
            return response;
}
    }
    public static OkHttpClient send(){
        return okHttpClient;
}
}
