HTTP POST请求的JAVA GET响应

Question

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

            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! ");
            }

谢谢你的建议

Answer 1

更改：

status == "201"

至：

status.equals("201")

Answer 2

字符串比较，如上所述。

status.equals("201")

或者您可以使用：

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

这里的所有状态
