openid 怎么获取

JS部分

wx.login({     success:function(code){         wx.request({           url:'test.php',           data:{             code:code           },           method:'POST',           header:{'content-type':'application/x-www-form-urlencoded;charset=UTF-8'},           success: function(res){             console.log(res)           }         })     } })

PHP部分（我只会PHP，要是其它语言的，你自己看着改吧）

$code = $_POST['code']; $url = 'https://api.weixin.qq.com/sns/jscode2session?appid=your_appid&secret=your_secret&grant_type=authorization_code&js_code='.$code; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_HEADER, 1); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); $data = curl_exec($curl); curl_close($curl); $data = explode("{",$data); $data = explode("}",$data[1]); echo '{'.$data[0].'}';
