实现小程序微信支付功能

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OpenidopenId: 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。

下附第一个 HttpClient类请注意更改：package com.keyan.whart.WhartSdk 改为自己得

继续 IWXPayDomain 类

package com.keyan.whart.WhartSdk;/*** 域名管理，实现主备域名自动切换*/
public abstract interface IWXPayDomain {/*** 上报域名网络状况* @param domain 域名。 比如：api.mch.weixin.qq.com* @param elapsedTimeMillis 耗时* @param ex 网络请求中出现的异常。*           null表示没有异常*           ConnectTimeoutException，表示建立网络连接异常*           UnknownHostException， 表示dns解析异常*/abstract void report(final String domain, long elapsedTimeMillis, final Exception ex);/*** 获取域名* @param config 配置* @return 域名*/abstract DomainInfo getDomain(final WXPayConfig config);static class DomainInfo{public String domain;       //域名public boolean primaryDomain;     //该域名是否为主域名。例如:api.mch.weixin.qq.com为主域名public DomainInfo(String domain, boolean primaryDomain) {this.domain = domain;this.primaryDomain = primaryDomain;}@Overridepublic String toString() {return "DomainInfo{" +"domain='" + domain + '\'' +", primaryDomain=" + primaryDomain +'}';}}}

继续： WXPayConfig

package com.keyan.whart.WhartSdk;import java.io.InputStream;public abstract class WXPayConfig {/*** 获取 App ID** @return App ID*/abstract String getAppID();/*** 获取 Mch ID** @return Mch ID*/abstract String getMchID();/*** 获取 API 密钥** @return API密钥*/abstract String getKey();/*** 获取商户证书内容** @return 商户证书内容*/abstract InputStream getCertStream();/*** HTTP(S) 连接超时时间，单位毫秒** @return*/public int getHttpConnectTimeoutMs() {return 6*1000;}/*** HTTP(S) 读数据超时时间，单位毫秒** @return*/public int getHttpReadTimeoutMs() {return 8*1000;}/*** 获取WXPayDomain, 用于多域名容灾自动切换* @return*/abstract IWXPayDomain getWXPayDomain();/*** 是否自动上报。* 若要关闭自动上报，子类中实现该函数返回 false 即可。** @return*/public boolean shouldAutoReport() {return true;}/*** 进行健康上报的线程的数量** @return*/public int getReportWorkerNum() {return 6;}/*** 健康上报缓存消息的最大数量。会有线程去独立上报* 粗略计算：加入一条消息200B，10000消息占用空间 2000 KB，约为2MB，可以接受** @return*/public int getReportQueueMaxSize() {return 10000;}/*** 批量上报，一次最多上报多个数据** @return*/public int getReportBatchSize() {return 10;}}

好了到现在为止无脑复制粘贴就结束了上面的复制过去请注意你的pom文件你的路径需要更改得不是复制过去啥都不管就能用得

接下来就是主要的类了下附代码：

基本就是这样了，可能会出一些错，但是整体运行下来是没有问题得，但是也只能最基础得微信支付功能，支付成功回调接口啊这些我还没有，也希望大佬可以补充，
