我搜索过社区中，查看了其他很多人的解决方案，一直没有找到解决方法，我是用户信息和手机号一起获取，是这个方向不能实现吗？ 前台代码: 授权登陆 js代码： login: function (res) {     var that=this;     wx.login({       success: function (e) {         var code = encodeURIComponent(e.code);         wx.getUserInfo({           lang: "zh_CN",           success: function (result) {             var encryptedData= encodeURIComponent(res.detail.encryptedData);             var iv=encodeURIComponent(res.detail.iv);             console.log(res.detail.iv)             wx.request({               url: 'xxxxxxxx',               data: {                 code: code,                 encryptedData:encryptedData,                 iv:iv,                 distribution:that.data.distribution               },               header: {                 "Content-Type": "application/x-www-form-urlencoded"               },               method: "post",               success: function (res) {}             })           }         })       }     })     // console.log(res)   }, 后台php代码： $post = $_POST; $code = urldecode($post['code']); $encryptedData = urldecode($post['encryptedData']); $iv = urldecode($post['iv']); // $phone = $post['phone']; // $sendCode = $post['sendCode']; $verifyUrl = "https://api.weixin.qq.com/sns/jscode2session?appid=" . $this->APPID . "&secret=" . $this->secret . "&js_code=" . $code . "&grant_type=authorization_code"; $verify = $this->curl($verifyUrl); $verify1 = json_decode($verify, true); $errCode = $this->decryptData($encryptedData, $iv, $verify1['session_key'], $data); 偶尔会出现-41003错误

后台代码： $receipt = file_get_contents("php://input"); if ($receipt == null) { $receipt = $GLOBALS['HTTP_RAW_POST_DATA']; } postman截图 [图片]
