Hello, friends, the following is the Ruoyi micro-service version that I use in the background of WeChat payment. Next, I will start from the front desk, explain the simple method of experimenting with WeChat payment step by step with the attached pictures, and start doing it.
The applet side confirms the payment button, and binds a @click event: getDetailsList The code is as follows:
<text class="mix-btn" @click="getDetailsList">确认支付</text>The calling method code is attached below:
//微信支付
async getDetailsList() {
let _this = this;
// 准备参数对象
const query = {
//名称
tetlo: this.name,
//订单号
money: this.price,
//用户的Openid
openId: this.openid,
}
// 发起请求
const res = await uni.$http.get('/PaySdk/pay', query) // ”/PaySdk/pay“ 为后台请求路径 query 为上面准备的参数 必要 我这里得订单号为此商品得ID 通过跳转页面传过来得
//下面得是请求后台成功后然会得不需要更改 res为上面请求成功后返回的参数 想知道是什么可以在这个位置 打一个console.log(res) 查看
uni.requestPayment({
provider: "wxpay",
orderInfo: res.data,
timeStamp: res.data.timeStamp,
nonceStr: res.data.nonceStr,
package: res.data.package,
signType: res.data.signType,
paySign: res.data.paySign,
success(res) {
_this.submit();
//uni.showToast 一个弹出框 这个不用多说了吧
uni.showToast({
title: '支付成功! 正在处理请稍后~',
icon: 'none'
})
//这个是支付成功后跳转到主页面 这个根据你个人需求 更改一下 我这个跳转时带有延时
setTimeout(function () {
uni.navigateTo({
// 要导航到的页面地址
url: '/pages/indexs?index=' + 0,
})
}, 3000)
},
fail(e) {
console.log(e);
uni.hideLoading();
uni.showToast({
title: '支付失败，请稍后再试',
icon: 'none'
})
}
})
},We will start our background code later, because I am using the Ruoyide micro-service version, and a separate module for WeChat interface processing is separated out, and my directory structure is as follows:
The following are the required classes. I created a folder separately, except for PaySdk, just copy and paste directly.
