用户第一次如果拒绝位置，但位置又是必须要授权的，为此在提交时会再次调用原先的获取位置方法，此时wx.authorize返回为fail，所以在fail中增加了 wx.openSetting的方法，但是没有用，请问是不是写错了，还是微信强制不允许。
if (res.authSetting['scope.userLocation'] != true) {
wx.authorize({
scope: 'scope.userLocation',
success() {
console.log('调用授权success')
that.getWxLocation();
},
fail: function (res) {
console.log('调用授权fail')
wx.openSetting({
success: (res) => {
if (res.authSetting['scope.userLocation'] = true) {
that.getWxLocation();
}
}
})
}
})
}
记录一下用户关于地址授权状态：未弹起授权，授权弹起未允许，授权弹起允许，再判断处理；
wx.openSetting那个接口已经改了，看文档吧：https://developers.weixin.qq.com/community/develop/doc/000cea2305cc5047af5733de751008?highLine=wx.openSetting
使用授权按钮操作后，点击后出现以下错误，请问是怎么回事。
