HTTP POST 请求的 JAVA GET 响应

Question

如何获取状态码或更好地了解消息是否已发送？ 我已经这样做了，但是当然它不起作用。

            httppost.setEntity(new StringEntity(message.toString()));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            String status = response.getStatusLine().toString();

            Log.d(CLASS_TAG + "showOnScreenMessage", "Message sent! ");
            Log.d(CLASS_TAG + "showOnScreenMessage", "Status : " + status );

            // if response == 201 , the message has be received, Set True to acknowledgment_message 
            if ( status == "201"){
                Log.d(CLASS_TAG + "showOnScreenMessage", "Message received! ");


            }else{
                // Do nothing already false
                Log.d(CLASS_TAG + "showOnScreenMessage", "Message not received! ");
            }

感谢您的建议

Answer 1

如上所述，字符串比较。

status.equals("201")

或者你可以使用：

response.getStatusLine().getStatusCode() != HttpStatus.SC_OK

所有状态here

Answer 2

变化：

status == "201"

到：

status.equals("201")
