微信小程序两种重新获取授权的解决方法

第一种:

在onLoad里面直接获取授权,拒绝时跳出弹框,提醒用户是否确定拒绝,如果点击获取授权,则调出微信自身的系统页面,获取个人信息,

wx.login({

success: function (res) {

var JSCODE = res.code

wx.getUserInfo({

lang: 'zh_CN',

success: function (res) {

console.log(res);

var userInfo = res.userInfo;

var cardNikeName = userInfo.nickName;

var avatarUrl = userInfo.avatarUrl;

var area = userInfo.province;

var encryptedData = res.encryptedData;

var iv = res.iv;

app.globalData.userInfo = res.userInfo;

wx.setStorageSync( "userInfo", res.userInfo)

var value = wx.getStorageSync( 'channel')

console.log(value)

wx.request({

url: 'https://laohuangli.intbull.com/little/little.jsp',

data: {

cmd: 'login',

channel: value,

app_id: "wxd1949f3130a58e73",

code: JSCODE,

encrypted_data: encryptedData,

iv: iv,

},

header: {

'content-type': 'application/json'

},

success: function (res) {

app.globalData.open_id = res.data.open_id;

console.log(res.data.open_id)

wx.setStorageSync( "open_id", res.data.open_id)

}

})

},

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,

})

}

})

}

}

})

}

}

})

}

})

}

})

第二种:

跳出弹框被拒绝,做一个按钮,点击还能跳出弹框

wx.getUserInfo({

success: function (res) {

console.log(res)

},

fail: function () {

}

})

在点击函数中调用,就可重复出现弹框
