微信中使用支付宝进行支付

微信中使用支付宝不能直接使用，由于微信内置浏览器的原因，在微信中使用支付宝时无法跳转出去，支付宝官网给出了实例文档
支付宝官网地址
下载后
在这里插入图片描述
将其例子融入到vue中使用
步骤：
第一步：将ap.js放在vue项目中
第二步：在需要使用的页面引入ap.js
第三步：使用ap.js里面的方法

注意事项：
在引入ap.js的时候需要注意，这个跟引入的方式有关联，经测试使用

import '../../../src/assets/js/ap';

引入没有问题，使用

import '@/assets/js/ap';

这样引用会有问题，
如果没有引用点击支付的时候不会进行任何操作
在页面中使用
在响应的点击事件中执行如下方法即可
这里的this.urlon是传入地址，及后端返回的支付地址

 _AP.pay(this.urlon);

编译打包后再同一目录下放入pay.htm

完整例子
支付的vue文件

<div class="login-btn">
<el-button type="primary" @click="alipay()">支付宝</el-button>
</div>
<script>
import '../../../src/assets/js/ap';
export default {data: function () {return {localurl: '',urlon: ''};},mounted() {},methods: {login_info() {this.$axios({url: 'https://www.qinhonor.com:9100/api/payinfo/',// url: 'https://www.singsoft.cn:8000/api/login',method: 'post',data: {openid: '041v9G0003ZcUK1GOd400Bwpo13v9G0K'}}).then((response) => {console.log(response.data, 'res');if (response.data.status == 200) {sessionStorage.setItem('user', this.param.username);sessionStorage.setItem('type', response.data.type);sessionStorage.setItem('permissions0', response.data.permissions0);sessionStorage.setItem('permissions1', response.data.permissions1);sessionStorage.setItem('permissions2', response.data.permissions2);sessionStorage.setItem('permissions3', response.data.permissions3);this.$router.push('/dashboard');} else {alert('您好！用户名或密码错误，请重试!');}}).catch(function (error) {});},alipay() {this.$axios({url: '后端地址',method: 'post',data: {out_trade_no: '这个订单编号随意写，不能重复（例如：041v9G0003ZcUK1GOd400Bwpo13v9G0K3）',total_fee: '0.01',subject: '99预约'}}).then((response) => {if (response.data.return == 'SUCESS') {let ids = response.data.return1;let ua = window.navigator.userAgent.toLowerCase();if (ua.match(/MicroMessenger/i) == 'micromessenger') {// alert('您好！微信内置浏览器');this.urlon = ids;_AP.pay(this.urlon);}} else {alert('您好！用户名或密码错误，请重试!');}});},}
};
</script>

到此成功

方式二：使用静态html
将demo_get.htm中的a标签地址修改成支付回调地址即可
