能弹出授权窗了，但是出现被拒绝

我的登录代码如下：

<template>
  <div  >
   <button open-type="getUserInfo" lang="zh_CN" class='btn' @getuserinfo="login">点击登录</button>
  </div>
</template>
<script type="text/ecmascript-6">
 import qcloud from 'wafer2-client-sdk'
 import config from '@/config'

        methods: {
    
            getWxLogin({encryptedData,iv,userinfo}) {
                const self = this
                 wx.login({
                    success(loginResult) {
                        console.log('loginResult', loginResult) 
                        var loginParams = {
                            code: loginResult.code,
                            encryptedData: encryptedData,
                            iv: iv
                        }
                        qcloud.setLoginUrl(config.loginUrl) 
                        qcloud.requestLogin({
                            loginParams,
                            success() {

                            },
                            fail(error) {

                        })
                    },
                    fail(loginError) {
                         console.log('登录失败', loginError)
