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:

$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,代码如下:

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代码如下:

$data=' {

     "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"

            }]

       }]

}';

$ch = curl_init($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($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data)));

$data = curl_exec($ch);

print_r($data);//创建成功返回：{"errcode":0,"errmsg":"ok"}
