php 通過curl post發送json資料執行個體_PHP教程

利用php curl發送json資料與curl post其它資料是一樣的，下面我來給大家總結幾個關於curl post發送json資料執行個體，希望能加深各位對curl post json資料的理解吧。

例1

代碼如下

複製代碼

$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);

例2

代碼如下

複製代碼

function http_post_data($url, $data_string) { $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json; charset=utf-8', 'Content-Length: ' . strlen($data_string)) ); ob_start(); curl_exec($ch); $return_content = ob_get_contents(); ob_end_clean(); $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); return array($return_code, $return_content); } $url = "http://xx.xx.cn"; $data = json_encode(array('a'=>1, 'b'=>2)); list($return_code, $return_content) = http_post_data($url, $data);

例3

代碼如下

複製代碼

$data=' { "button":[ { "type":"click", "name":"今日歌曲", "key":"V1001_TODAY_MUSIC" }, { "type":"click", "name":"歌手簡介", "key":"V1001_TODAY_SINGER" }, { "name":"菜單", "sub_button":[ { "type":"click", "name":"hello word", "key":"V1001_HELLO_WORLD" }, { "type":"click", "name":"贊一下我們", "key":"V1001_GOOD" }] }] }'; $ch = curl_init($urlcon); //請求的URL地址 curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//$data JSON類型字串 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data))); $data = curl_exec($ch); print_r($data);//建立成功返回：{"errcode":0,"errmsg":"ok"}

小結，我們發現最核心的一句代碼就是Content-Type: application/json;這個是檔案格式類型了。
