哈喽，朋友们，下面得微信支付我的后台使用的 若依微服务版 下面我会先从前台开始，附图及一步一步讲解实验微信支付得简单方法，开搞。
小程序端确认支付按钮，绑定一个@click事件：getDetailsList 代码如下：
<text class="mix-btn" @click="getDetailsList">确认支付</text>下附调用方法代码：
//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'
})
}
})
},后面开始我们得后台代码， 因为我用的是若依得微服务版本，单独分出来了一个微信接口处理得单独模块， 下面我的目录结构：
下面就是需要得类，我是单独得创建了一个文件夹，这个里面除了PaySdk 以外 直接复制粘贴就可以了。
