问题 Should I use the GET or POST method when sending information to a server in the body of the HTTP request? There are no query parameters appended to the URL, the server will inspect the body of the request for what it needs. 回答1: GET extracts parameters from the request URL. POST extracts parameters from the request body. So you need POST. 回答2: A nice description and interesting discussion on the topic: http://thinkvitamin.com/code/the-definitive-guide-to-get-vs-post/ 回答3: POST should be used

问题 I am trying to create a simple app where an array of integers is generated on the server and sent to the client.

Due to the fact that you could

Everything in Android app works fine. On the other side, in iOS app all of the POST responses are OK, the problem is just with GET responses. I tracked the requests, all of them are received on the server side app and regarding the logs, the server sends the response to the client but the client didn't get any response. None

问题 Is it possible to make GET & POST requests in Java or another language such that you don't care about what is returned? As in just sending the requests but not wanting to receive any responses? 回答1: Whether you care about the response or not, it will be sent. The HTTP protocol specifications say that it must be. If you don't care about the response, your client could just close the connection immediately after sending the request. But the chances are that you do want to know that the request
