我如何才能意识到android将一个字符串发送到php页面并获取JSON数组？

Question

I know how to use HttpGet so that I can execute a httpget to one php page to get the JSONArray after querying the database. Now my problem is that I should first send one string: username to the php page, and then this php page should use this string(username) to query in mysql and return the result as a JSONArray. Should I just use HttpPost to post the string to php and obtain the response？Or any other methods？

Answer 1

You shouldn't use the POST http method (HttpPost) for this, POST is when the request causes a change in the server of some type. Querying a database to simply get some registers can be perfectly done using GET http method (HttpGet), pass the "user" value as a URL parameter and you should be done.
