2、PHP代码

#key=企业微信机器人中的值
$webhook = "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=";   #这里需要修改
# curl初始化
$curl = curl_init();
#需要推送的url
curl_setopt($curl, CURLOPT_URL, $webhook);
curl_setopt($curl, CURLOPT_POST, 1);
#content必须是utf8编码
curl_setopt($curl, CURLOPT_HTTPHEADER,array('Content-Type: application/json;charset=utf-8'));
#content 为需要推送的内容
$post_data = '
   {
        "msgtype": "text",
        "text": {
            "content": "hello world"
        }
   }';
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
$data = curl_exec($curl);
curl_close($curl);
?>
