如何POST一个JSON格式的数据给Restful服务

在Android/java平台上实现POST一个json数据：

JSONObject jsonObj = new JSONObject(); jsonObj.put("username", username); jsonObj.put("apikey", apikey); // Create the POST object and add the parameters HttpPost httpPost = new HttpPost(url); StringEntity entity = new StringEntity(jsonObj.toString(), HTTP.UTF_8); entity.setContentType("application/json"); httpPost.setEntity(entity); HttpClient client = new DefaultHttpClient(); HttpResponse response = client.execute(httpPost);

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：

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

PHP用cUrl实现：

$data = array("name" => "Hagrid", "age" => "36");                                                                    
$data_string = json_encode($data);     
$ch = curl_init('http://api.local/rest/users');      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                          
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                 
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string))         
);                                                                                                                   
$result = curl_exec($ch);
