Question

我有一个从PHP读取Json的代码，它可以工作，但它只从PHP读取一个JSON，我需要从android发送一些数据到php，然后读取它获取请求的数据。

有人可以帮助我将这些内容包含在该代码中吗？

PHP / JSON阅读工作代码：我需要在那里实现发送，但我不知道从哪里开始

Answer 1

HttpClient httpclient = new DefaultHttpClient();
String jsonString = "Some json string";
HttpPost httppost = new HttpPost(urls[0]);
httppost.setEntity(new StringEntity(jsonString, HTTP.UTF_8));

Answer 2

尝试在http请求中使用参数：

new GetSmsTask().execute("http://iatek.eu/sys/getsms.php"+"?"+arg1+"="+val1);

Answer 3

您可以通过发帖请求或获取请求将数据发送到服务器。检查此示例以将后期数据发送到服务器。
