【问题描述】：
编辑：除了下面的答案
我走到了尽头。我找了很多简单的 http post 请求的例子，但我就是无法让它工作......
我的要求其实很简单：“我做错了什么？”
当我测试应用时，它显示“不幸的是已停止”。
我会给你必要的代码：
我所有的导入

必要的mainactivity.java函数
public void sync_btn_click(View v) {
//Sync button click
boolean varif = postData("hans");
Toast.makeText(getApplicationContext(), String.valueOf(varif), Toast.LENGTH_SHORT).show();
}
public boolean postData(String verif_code) {
//Make new requesting clients
HttpClient sync_client = new DefaultHttpClient();
HttpPost get_verif = new HttpPost("http://www.google.nl");
// Building post parameters, key and value pair
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
nameValuePair.add(new BasicNameValuePair("email", "user@gmail.com"));
nameValuePair.add(new BasicNameValuePair("password", "encrypted_password"));
//Encode post values
try{
get_verif.setEntity(new UrlEncodedFormEntity(nameValuePair));
}catch (UnsupportedEncodingException e) {
// writing error to Log
e.printStackTrace();
}
//Make http request
try {
HttpResponse response = sync_client.execute(get_verif);
// writing response to log
Log.d("Http Response:", response.toString());
return true;
} catch (ClientProtocolException e) {
// writing exception to log
e.printStackTrace();
return false;
} catch (IOException e) {
// writing exception to log
e.printStackTrace();
return false;
}
}

我觉得这不是请求，而是别的什么。但我真的不知道是什么。
提前致谢，
鲁德
答案的补充 感谢 Jitesh Upadhyay，我找到了答案。我没有使用 AsyncTask 来执行请求。
我找到了this site，这正是我想做的事情。
希望这对你也有帮助！
