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。 混淆
