// index.js
const defaultAvatarUrl = 'https://mmbiz.qpic.cn/mmbiz/icTdbqWNOwNRna42FI242Lcia07jQodd2FJGIYQfG0LAJGFxM4FbnQP6yfMxBgJ0F3YRqJCJ1aPAK2dQagdusBZg/0'
Page({
data: {
motto: 'Hello World',
userInfo: {
avatarUrl: defaultAvatarUrl,
nickName: '',
},
hasUserInfo: false,
canIUseGetUserProfile: wx.canIUse('getUserProfile'),
canIUseNicknameComp: wx.canIUse('input.type.nickname'),
},
bindViewTap() {
wx.navigateTo({
url: '../logs/logs'
})
},
onChooseAvatar(e) {
const { avatarUrl } = e.detail
const { nickName } = this.data.userInfo
this.setData({
"userInfo.avatarUrl": avatarUrl,
hasUserInfo: nickName && avatarUrl && avatarUrl !== defaultAvatarUrl,
})
},
onInputChange(e) {
const nickName = e.detail.value
const { avatarUrl } = this.data.userInfo
this.setData({
"userInfo.nickName": nickName,
hasUserInfo: nickName && avatarUrl && avatarUrl !== defaultAvatarUrl,
})
},
getUserProfile(e) {
// 推荐使用wx.getUserProfile获取用户信息，开发者每次通过该接口获取用户个人信息均需用户确认，开发者妥善保管用户快速填写的头像昵称，避免重复弹窗
wx.getUserProfile({
desc: '展示用户信息', // 声明获取用户个人信息后的用途，后续会展示在弹窗中，请谨慎填写
success: (res) => {
console.log(res)
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
})
},
})
