open-data
代码：
<open-data type="groupName"></open-data>
<view>
昵称：<open-data type="userNickName"></open-data>
</view>
<view>
头像：<open-data type="userAvatarUrl" style="display: block; width: 100px;"></open-data>
</view>
<view>
性别：<open-data type="userGender" lang="zh_CN"></open-data>
</view>
<view>
地址:
<open-data type="userCountry" lang="zh_CN"></open-data>
<open-data type="userProvince" lang="zh_CN"></open-data>
<open-data type="userCity" lang="zh_CN"></open-data>
<open-data type="userCity"></open-data>
</view>
<view>
语言:
<open-data type="userLanguage"></open-data>
</view>
效果
授权获取用户信息
代码
<view>
<block wx:if="avatarUrl">
<image style="display: block" src="avatarUrl" />
<text>nickName</text>
</block>
<button wx:if="!avatarUrl" open-type="getUserInfo" bindgetuserinfo="bindgetuserinfo">授权登录</button>
</view>
// pages/my/my.js
Page(
/**
* 页面的初始数据
*/
data:
avatarUrl: '',
nickName: ''
,
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options)
wx.getSetting(
complete: (res) =>
if (res.authSetting['scope.userInfo'])
// 已经授权，可以直接调用 getUserInfo 获取头像昵称
wx.getUserInfo(
success: (res) =>
console.log("已授权", res.userInfo)
let avatarUrl, nickName = res.userInfo;
this.setData(
avatarUrl,
nickName
);
)
else
console.log("未授权");
,
)
,
/**
* 点击授权按钮
*/
bindgetuserinfo(e)
console.log(e.detail.userInfo);
let avatarUrl, nickName = e.detail.userInfo;
this.setData(
avatarUrl,
nickName
);
)
效果
页面分享
/**
* 分享
*/
onShareAppMessage()
return
title: '我的页面分享',
path: 'pages/my/my'
,
- 页面右上角三个点分享，对应页面无分享代码，则不能分享
- 分享图可以设置，没设置为当前页面截图
获取收货地址
/**
* 获取地址
*/
handleAddress()
wx.chooseAddress(
complete: (res) =>
console.log("res", res);
// "errMsg":"chooseAddress:ok","userName":"张三","nationalCode":"510000","telNumber":"020-81167888","postalCode":"510000","provinceName":"广东省","cityName":"广州市","countyName":"海珠区","detailInfo":"新港中路397号"
,
)
打开地图选择位置
handleLocation()
wx.chooseLocation(
complete: (res) =>
console.log("res", res);
,
)
,
直接获取位置信息
handleGetLocation()
wx.getLocation(
type: 'wgs84',
success (res)
console.log("res", res);
const latitude = res.latitude;
const longitude = res.longitude;
const speed = res.speed;
const accuracy = res.accuracy;
wx.openLocation(
latitude,
longitude,
scale: 18
)
)
获取地址完整版
utils/asyncWx.js
/**
* promise 形式的 getSetting
*/
export const getSetting = () =>
return new Promise((resolve, reject) =>
wx.getSetting(
success: res =>
resolve(res);
,

* promise 形式的 chooseAddress
*/

*/

return new Promise((resolve, reject) =>
wx.openSetting(
success: res =>
resolve(res);
,
fail: (err) =>
resolve(err);
);
);
address.js
import
getSetting,
chooseAddress,
openSetting
from "../../utils/asyncWx";
Page(
async handleChooseAddress()
try
// 1. 获取 权限状态
const res1 = await getSetting();
const scopeAddress = res1.authSetting["scope.address"];
// 2. 判断 权限状态
if (scopeAddress === false)
// 3. 先诱导用户打开授权界面
await openSetting();
// 4. 调用获取收获地址的 api
// scopeAddress === true || scopeAddress === undefined
const res2 = await chooseAddress();
console.log(res2)
catch (error)
console.log(error)

支付流程
payOrder.wxml
<view>
<button bindtap="handlePayOrder">支付</button>
</view>
payOrder.js
// pages/payOrder/payOrder.js

const token = wx.getStorageSync('token');
// 2. 判断权限
if (!token)
wx.navigateTo(
url: '/pages/auth/auth'
);
return;
// 3. 创建订单
// 3.1 准备 请求头参数
const header =
Authorization: token
;
// 3.2 准备 请求体参数
const order_price = this.data.totalPrice;
const consignee_addr = this.data.address.all;
const goods = this.data.goods;
// 4. 准备发送请求 创建订单
const
order_number
= await request(
url: "/my/orders/create",
method: "POST",
header,
data:
order_price,
consignee_addr,
goods
);
// 5 发起 预支付接口
const
pay
= await request(
url: "/my/orders/req_unifiedorder",
method: "POST",
header,
data:
order_number // 订单编号
);
// 6. 发起微信支付
const
timeStamp,
nonceStr,
package,
paySign
= pay;
await wx.requestPayment(
timeStamp: 'timeStamp', //时间戳从1970年1月1日00:00:00至今的秒数,即当前的时间,
nonceStr: 'nonceStr', //随机字符串，长度为32个字符以下,
package: 'package', //统一下单接口返回的 prepay_id 参数值，提交格式如：prepay_id=*,
paySign: 'paySign', //签名,具体签名方案参见小程序支付接口文档,
success: res => ,
fail: () => ,
complete: () =>
);
// 7. 查询后台 订单状态
const res = await request(
url: "/my/orders/chkOrder",
method: "POST",
header,
data:
order_number
);
await wx.showToast(
title: '支付成功'
);
// 8. 支付成功了，跳转到订单页面
wx.navigateTo( url: '/pages/order/order' );
catch (error)
await wx.showToast(
title: '支付失败'
);
)
auth.wxml
<view>
<button
bindtap="handlePayOrder"
type="primary"
plain="true"
open-type="getUserInfo"
bindgetuserinfo="handleGetUserInfo"
>支付</button>
</view>
auth.js
// pages/auth/auth.js
Page(
// 1. 获取用户信息 可以通过封装promise简化代码
handleGetUserInfo(e)
try
const encryptedData, iv, signature, rawData = e.detail;
// 2. 获取小程序登录后的code
wx.login(
success: res =>
const code = res;
// 3. 发送请求，获取用户的token
const loginParams =
encryptedData,
rawData,
iv,
signature,
code
;
wx.request(
url: '/users/wxlogin', //开发者服务器接口地址",
data: loginParams, //请求的参数",
method: 'POST',
complete: (result) =>
console.log(result);
// 假如成功
if (true)
// 4. 把token存入缓存中，同时跳转回上一个页面
const token = token: "ZDFAW3ERSDFSD" || result;
wx.setStorageSync('token',token);
wx.navigateBack(
delta: 1 //返回的页面数，如果 delta 大于现有页面数，则返回到首页,
