本文档主要讲述的是android使用JSON进行网络数据交换；JSON（JavaScript Object Notation）是一种轻量级的数据交换格式，易于阅读和编写，同时也易于机器解析和生成，非常适合于服务器与客户端的交互。JSON采用与编程语言无关的文本格式，但是也使用了类C语言的习惯，这些特性使JSON成为理想的数据交换格式。希望本文档会给有需要的朋友带来帮助；感兴趣的朋友可以过来看看
$.ajax({ url:url, type:"POST", data:data, contentType:"application/json; charset=utf-8", dataType:"json", success:function(){...}})PHP用cUrl实现：
<span> 1</span><span>$data</span> = <span>array</span>("name" => "Hagrid", "age" => "36"<span>);
</span><span> 2</span><span>$data_string</span> = json_encode(<span>$data</span><span>);
