用curl可执行如下命令：

curl -l -H "Content-type: application/json" -X POST -d '{"phone":"13521389587","password":"test"}' http://domain/apis/users.json

用jQuery：

<code><span>$<span>.<span>ajax<span>({<span>  url<span>:<span>url<span>,<span>  type<span>:<span>"POST"<span>,<span>  data<span>:<span>data<span>,<span>  contentType<span>:<span>"application/json; charset=utf-8"<span>,<span>  dataType<span>:<span>"json"<span>,<span>  success<span>:<span><span>function<span>(){<span><span>...<span><span>}<span><span>})</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

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>$data</span><span>); 
</span><span> 3</span><span>$ch</span> = curl_init('http://api.local/rest/users'<span>); 
</span><span> 4</span> curl_setopt(<span>$ch</span>, CURLOPT_CUSTOMREQUEST, "POST"<span>); 
</span><span> 5</span> curl_setopt(<span>$ch</span>, CURLOPT_POSTFIELDS, <span>$data_string</span><span>);
</span><span> 6</span> curl_setopt(<span>$ch</span>, CURLOPT_RETURNTRANSFER, <span>true</span><span>);
</span><span> 7</span> curl_setopt(<span>$ch</span>, CURLOPT_HTTPHEADER, <span>array</span><span>( 
</span><span> 8</span> 'Content-Type: application/json',
<span> 9</span> 'Content-Length: ' . <span>strlen</span>(<span>$data_string</span><span>)) 
</span><span>10</span><span>); 
</span><span>11</span><span>$result</span> = curl_exec(<span>$ch</span>);
