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：
1 $data = array("name" => "Hagrid", "age" => "36"); 2 $data_string = json_encode($data); 3 $ch = curl_init('http://api.local/rest/users'); 4 curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 5 curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 6 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 7 curl_setopt($ch, CURLOPT_HTTPHEADER, array( 8 'Content-Type: application/json', 9 'Content-Length: ' . strlen($data_string)) 10 ); 11 $result = curl_exec($ch);
