JMeter测试失败的HTTP请求(HTTP request on JMeter test failure)

 要建立与服务器的连接，您需要在服务器端有一个脚本来接收输入连接并对其执行某些操作。 所以第一步是编写一个简单的脚本（我建议使用PHP）。 
 
 现在，您必须创建从android到所述服务器的连接。 您可以使用AsyncTask或生成新线程来执行任何与网络相关的操作，因为没有网络操作可以在UI线程上运行。 示例代码： 
 
public class BackgroundTask extends AsyncTask<Void,Void,Void>{

@Override
protected Void doInBackground(Void... params) {
  //perform network operation and return response
  URL url = new URL("link.to.your.VPS.script");
  //now make a connection
  HttpUrlConnection conn = (HttpUrlConnection) url.openConnection();
  //get response code
  conn.getResponseCode();

  return null;
}

@Override
protected void onPostExecute(Void v){

}
}
 
 您可以从您的活动中运行此代码 
 
new BackgroundTask().execute();
 
 这只是一个启动者。 您可以通过将参数发布到PHP代码并将PHP代码连接到MySql DB来改进这一点 
 
 PS一年前我就在你的位置，因此我非常乐意提供帮助。 但是下次你在StackOverfllow上发帖时，请确保你的问题是具体的。 

To establish a connection to server, you need to have a script at the server end to receive and perform some action on input connection. So first step would be to write a simple script (I would suggest PHP). 
 
Now, you must create a connection from android to the said server. You can use AsyncTask or spawn a new thread to perform any network related operations, because no network operation can run on UI thread. Sample code:
 
public class BackgroundTask extends AsyncTask<Void,Void,Void>{

@Override
protected Void doInBackground(Void... params) {
  //perform network operation and return response
  URL url = new URL("link.to.your.VPS.script");
  //now make a connection
  HttpUrlConnection conn = (HttpUrlConnection) url.openConnection();
  //get response code
  conn.getResponseCode();

  return null;
}

@Override
protected void onPostExecute(Void v){

}
}
 
You can run this code from your activity by 
 
new BackgroundTask().execute();
 
This is just a starter. You can improve on this by posting parameters to your PHP code and connect PHP code to MySql DB 
 
P.S. I was in your place a year ago and hence I am more than happy to help. But the next time you post on StackOverfllow, make sure your question is specific.
