RetrofitUtils

Android Studio
//retrofit
compile 'com.squareup.okio:okio:1.14.0'
compile 'com.squareup.okhttp3:okhttp:3.10.0'
compile 'com.squareup.retrofit2:retrofit:2.4.0'
compile 'com.squareup.retrofit2:converter-scalars:2.3.0'

目前对以下需求进行了封装

  一般的get请求
  一般的post请求
  基于Http Post的文件上传（类似表单）
  文件下载/加载图片
  上传下载的进度回调
  支持取消某个请求
  支持自定义Callback
  支持HEAD、DELETE、PATCH、PUT

配置RetrofitUtils

public class MyApplication extends Application
{
@Override
public void onCreate()
{
super.onCreate();

OkHttpClient okHttpClient = new OkHttpClient.Builder()
               .connectTimeout(20000L, TimeUnit.MILLISECONDS)
               .readTimeout(20000L, TimeUnit.MILLISECONDS)
               .addInterceptor(new LoggingInterceptor())
               .build();
       HttpCreator.init(Urls.URL_BASE_HOST, okHttpClient);
  }

}

}

取消所有请求

RetrofitUtils.cancel();

根据tag取消请求

目前对于支持的方法都添加了最后一个参数Object tag，取消则通过RetrofitUtils.cancelTag(tag)执行。

例如：在Activity中，当Activity销毁取消请求：

@Override

protected void onDestroy()

{

  super.onDestroy();
  //可以取消同一个tag的
 RetrofitUtils.cancelTag(this);//取消以Activity.this作为tag的请求

}

比如，当前Activity页面所有的请求以Activity对象作为tag，可以在onDestory里面统一取消。
