1.首先要有一个按钮
<view name="authorizemodal">
<view class="drawer_screen" wx:if="{{isauthorizeModal}}">
<view class="drawer_box fishqccenter phonechoosebox">
<view>
<image style="90%;" src="https://try.fishqc.com/img/Try-sm/authorization.png" mode="widthFix"></image>
</view>
<view>
<button class="authorization-btn" open-type="getUserInfo" bindgetuserinfo="getlogincode" style="border-radius: 1rpx"></button>
</view>
<!-- <view class="weChatAuth">授权提示</view>
<view class="phonechoosetxt">放心试小程序需授权获取微信权限信息</view>
<view class="phonechoosebtncontain">
<view class="getPhoneContain">
<button class="author-btn" open-type="getUserInfo" bindgetuserinfo="getlogincode" style="border-radius: 1rpx">授权</button>
</view>
</view> -->
</view>
</view>
</view>
2.授权的js代码
var app = getApp()
Component({
properties: {
},
data: {
isauthorizeModal:false
},
methods: {
toasttips: function (text, icon, time) {
wx.showToast({
title: text == null ? '' : text,
icon: icon,
duration: time == null ? '1000' : time
})
},
getlogincode: function () {
var that = this;
wx.login({
success: function (res) {
if (res.code) {
var logincode = res.code
// 弹窗授权
wx.getUserInfo({
success: function (res) {
if (res.errMsg == 'getUserInfo:ok') {
var encryptedData = res.encryptedData
var iv = res.iv;
that.setData({
isauthorizeModal: false
})
that.triggerEvent('myevent',{arg:false})
that.WeixinLogin(logincode, encryptedData, iv);
}
},
fail: function (res) {
// console.log('点击确认取消')
that.checkauthorize();
}
})
} else {
// console.log('登录失败！' + res.errMsg)
}
}
});
},
// 检查是否授权过
checkauthorize: function () {
var that = this;
wx.getSetting({
success(res) {
// 没有授权过的，进入如下
if (!res.authSetting['scope.userInfo']) {
that.authorizemodal();
}else{
that.setData({
isauthorizeModal:false
})

}
}
})
},
// 授权失败，弹窗
