php 通过curl post发送json数据实例

利用php curl发送json数据与curl post其它数据是一样的,下面我来给大家总结几个关于curl post发送json数据实例,希望能加深各位对curl post json数据的理解吧。

例1代码如下:

<?php
$data = array(
    "name" => "Hagrid",
    "age" => "36"
);
$data_string = json_encode($data);
$ch = curl_init(&#39;http://api.local/rest/users&#39;);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    &#39;Content-Type: application/json&#39;,
    &#39;Content-Length: &#39; . strlen($data_string)
));
$result = curl_exec($ch);
?>

例2,代码如下:

<?php
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(
        &#39;Content-Type: application/json; charset=utf-8&#39;,
        &#39;Content-Length: &#39; . 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";
$data = json_encode(array(
    &#39;a&#39; => 1,
    &#39;b&#39; => 2
));
list($return_code, $return_content) = http_post_data($url, $data);
?>

例3代码如下:

<?php
$data = &#39; { 
     "button":[ 
     {     
          "type":"click", 
          "name":"今日歌曲", 
          "key":"V1001_TODAY_MUSIC" 
      }, 
      { 
           "type":"click", 
           "name":"歌手简介", 
           "key":"V1001_TODAY_SINGER" 
      }, 
      { 
           "name":"菜单", 
           "sub_button":[ 
            { 
               "type":"click", 
               "name":"hello word", 
               "key":"V1001_HELLO_WORLD" 
            }, 
            { 
               "type":"click", 
               "name":"赞一下我们", 
               "key":"V1001_GOOD" 
            }] 
       }] 
 }&#39;;
$ch = curl_init($urlcon); //请求的URL地址
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //$data JSON类型字符串
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    &#39;Content-Type: application/json&#39;,
    &#39;Content-Length: &#39; . strlen($data)
));
$data = curl_exec($ch);
print_r($data); //创建成功返回：{"errcode":0,"errmsg":"ok"}
?>

小结,我们发现最核心的一句代码就是Content-Type: application/json;这个是文件格式类型了.
