1. compile ‘com.loopj.android:android-async-http:1.4.9‘:

params.addHeader(HTTP.CONTENT_TYPE,
"application/x-www-form-urlencoded;charset=UTF-8");

2. compile ‘org.xutils:xutils:3.2.2‘:

Toast.makeText(getApplication(), "cancle", Toast.LENGTH_SHORT).show();
}
// 注意:如果是自己onSuccess回调方法里写了一些导致程序崩溃的代码，也会回调道该方法，因此可以用以下方法区分是网络错误还是其他错误
// 还有一点，网络超时也会也报成其他错误，还需具体打印出错误内容比较容易跟踪查看

// ...
} else { // 其他错误

// 不管成功或者失败最后都会回调该接口

});
3. 自带的http:
运用原生Java Api发送简单的Get请求、Post请求步骤
- 通过统一资源定位器（java.net.URL）获取连接器（java.net.URLConnection）
- 设置请求的参数
- 发送请求
- 以输入流的形式获取返回内容
- 关闭输入流
