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"}'
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);
