POST一个JSON格式的数据给Restful服务实例详解


            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);
