最近刚好在做一个小程序的简单开发，故准备将其中的一些要点记录下，以备日后参考
相信最近在开发小程序的小伙伴们都清楚，官方将授权功能修改了（一句mmp不知道能不能引起共鸣~）。害我找了半天的原因….
老式授权功能：
var openId = (wx.getStorageSync('openId'));
if (openId) {
wx.getUserInfo({
success: function (res) {
wx.request({
url: '',
data: res,
method: 'POST',
success: function (res) {
console.log('submit success');
// 判断是否为渠道商
if (is) {
app.editTabBar2();
} else {
app.editTabBar();
}
},
fail: function (res) {
console.log('submit fail');
},
complete: function (res) {
console.log('submit complete');
}
})
that.setData({
nickName: res.userInfo.nickName,
avatarUrl: res.userInfo.avatarUrl,
})
},
fail: function () {
// fail
console.log("获取失败！")
},
complete: function () {
// complete
console.log("获取用户信息完成！")
}
})
} else {
wx.login({
success: function (res) {
console.log(res);
if (res.code) {
console.log(111);
wx.getUserInfo({
withCredentials: true,
success: function (res_user) {
console.log(res_user);
wx.request({
// 后台接口地址
url: '',
data: {
code: res.code,
encryptedData: res_user.encryptedData,
iv: res_user.iv
},
method: 'GET',
header: {
'content-type': 'application/json'
},
success: function (res) {
// 判断是否为渠道商
if (is) {
app.editTabBar2();
} else {
app.editTabBar();
}
// this.globalData.userInfo = JSON.parse(res.data);
that.setData({
nickName: res.data.nickName,
avatarUrl: res.data.avatarUrl,
})
wx.setStorageSync('openId', res.data.openId);
}
})
}, fail: function () {
wx.showModal({
title: '警告通知',
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) {
console.log(res);
if (res.confirm) {
wx.openSetting({
success: (res) => {
console.log(res);
// 如果用户重新同意了授权登录
if (res.authSetting["scope.userInfo"]) {
console.log(22)
wx.login({
success: function (res_login) {
if (res_login.code) {
wx.getUserInfo({
withCredentials: true,
success: function (res_user) {
console.log(res_user)
wx.request({
url: '',
data: {
code: res_login.code,
encryptedData: res_user.encryptedData,
iv: res_user.iv
},
method: 'GET',
header: {
'content-type': 'application/json'
},
success: function (res) {
// 判断是否为渠道商
if (is) {
app.editTabBar2();
} else {
app.editTabBar();
}
that.setData({
nickName: res.data.nickName,
avatarUrl: res.data.avatarUrl,
})
wx.setStorageSync('openId', res.data.openId);
}
})
}
})
}
}
});
}
}, fail: function (res) {
wx.showModal({
title: '提示',
content: '您点击了拒绝授权，将只能允许程序浏览功能',
success: function (res) {
if (res.confirm) {
console.log('用户点击确定')
}
}
})
}
})
}
}
})
}, complete: function (res) {
}
})
}
}
})
}新式授权功能（美名曰：提升用户的体验，不过也确实如此哦~）
需要事件操作调用才能授权
wxml
<button open-type="getUserInfo" lang="zh_CN" bindgetuserinfo="onGotUserInfo">获取用户信息</button>js
/**
* 获取用户信息
*/
onGotUserInfo: function (e) {
wx.setStorageSync("userInfo",e);
console.log(e);
console.log(e.detail)
console.log(e.detail.errMsg)
console.log(e.detail.userInfo)
console.log(e.detail.rawData)
},
