小程序授权怎么写 ， 用户点击取消授权 调用 wx.authorize

点击获取授权

onLoad: function (options) {
console.log("onLoad=====");
var that=this;
wx.getUserInfo({
  success:function(res){
    var userInfo = res.userInfo;
    that.setData({
      nickName: userInfo.nickName,
      avatarUrl: userInfo.avatarUrl,
    })
  },fail:function(){
    wx.showModal({
      title: '警告',
      content: '您点击了拒绝授权,将无法正常显示个人信息,点击确定重新获取授权。',
      success:function(res){
        if (res.confirm){
          wx.openSetting({
            success: (res) => {
              if (res.authSetting["scope.userInfo"]){////如果用户重新同意了授权登录
                wx.getUserInfo({
                  success:function(res){
                    var userInfo = res.userInfo;
                    that.setData({
                      nickName:userInfo.nickName,
                      avatarUrl:userInfo.avatarUrl,
                    })
                  }
                })
              }
            },fail:function(res){
              }
            }) 
          }
        }
      })
     }, complete: function (res){
    }
  })

}

或者

openSet: function () {
var _self = this;
wx.openSetting({
  success: (res) => {
    if (!res.authSetting['scope.userInfo']) {
      wx.showModal({
        title: '提示',
        content: '小程序需要授权',
        showCancel: false,
        success: function (res) {
             if (res.confirm) {
                _self.openSet();
            }
        }
      });
    } else {
          _self.wxLogin();
      }
  }
})

},
