uni-app 微信支付

<h4 class="md-end-block md-heading md-focus">小程序支付 </h4>
先看官方文档 https://pay.weixin.qq.com/wiki/doc/apiv3/open/pay/chapter2_8_2.shtml
知晓有那些比不可少的流程，之后后端确定返回的参数值，用于前端支付。参数值必须一一对应，不然支付会失败
<div class="cnblogs_code">
<pre>uni.requestPayment({
 timeStamp: data.timeStamp, //当前的时间
 nonceStr: data.nonceStr, //随机字符串
 package: data.package, //统一下单接口返回的 prepay_id 参数值
 signType: data.signType, //签名算法，暂支持 MD5。
 paySign: data.paySign, //签名
 success(res) {
 console.log('成功', res);
 },
 fail: (res) => {
 console.log('失败', res);
 },
})</pre>
</div>
小程序支付相对简单。支付的订单信息多要在后端生成。返回订单信息给前端调用支付API
<h4 class="md-end-block md-heading">APP支付</h4>
app支付方法和小程序基本相同，就是app要配置的地方不少
<pre></pre>
还是先看开发官方文档，基础的准备好。https://pay.weixin.qq.com/wiki/doc/apiv3/apis/chapter3_2_4.shtml
<pre></pre>
之后在uni的目录中找到manifest.json 打开选择app模卡--支付前面打个勾

这边只对微信支付，所以微信支付勾上，把微信平台的appid 放到对应的输入框里面
<div class="cnblogs_code">
<pre> //获取服务供应商
 uni.getProvider({
 service: 'payment',
 success: (res) => {
 console.log('getProvider', res) //服务类型：payment
 console.log('服务类型', res.provider) //返回的是微信支付宝
 //在这里请求接口拿到返回的订单数据用于调起支付
 that.sponsorPro(res.data) // 支付 res.data 为后端返回的订单信息
 //这个判断是否有微信不要加真机调试不会过测试可以过
 if(res.provider.indexOf('wxpay')){}
 }
})</pre>
</div>
发起支付 
md5().toUpperCase() 截取签名前30位为小写转大写 
md5为单独的一个js，代码在最后
<div class="cnblogs_code">
<pre>sponsorPro(data) {
//data 为后端的参数
let info = {
 "appid": data.appId,
 "partnerid": data.mchid,
 "package": 'Sign=WXPay',
 "package": data.package,
 "noncestr": data.noncestr,
 "timestamp": data.timestamp,
 // "sign": data.paySign,
 "sign": md5(data.sign).toUpperCase(),
 }
console.log('发起支付', info);
uni.requestPayment({
 provider: 'wxpay',
 signType: "MD5",
 orderInfo: info,
 success(res) {
 console.log('成功:' + JSON.stringify(res));
 },
 fail(err) {
 console.log('失败:' + JSON.stringify(err));
 }
})
} </pre>
</div>
info 的参数和官方返回的参数必须一致
<img src="https://img2020.cnblogs.com/blog/2237618/202105/2237618-20210522163229205-302449210.png" alt="" loading="lazy">
<h4 class="md-end-block md-heading md-focus">判断微信是否安装</h4>
<div class="cnblogs_code">
<pre>if (plus.runtime.isApplicationExist({
 pname: 'com.tencent.mm',
 action: 'weixin://'
})) {
 console.log("微信应用已安装");
} else {
 console.log("微信应用未安装");
}</pre>
</div>
可以用上面这个判断微信是否安装
官方地址 http://www.html5plus.org/doc/zh_cn/runtime.html#plus.runtime.isApplicationExist
<h4 class="md-end-block md-heading">微信支付调用失败 General errors","errCode":-100,"code":-100 </h4>
payment微信:-1 是微信的错误代码提示 
"errCode":-100," code":-100 为uni-app 错误代码提示
特别要注意第一次提交时报的是什么错误，这样对症下药
要是提示：包名（签名）与开放平台包名（签名）不一致，先检查打包的包名（签名）是什么，然后对比与线上的名字一致

下载安装到手机打开输入包名签名
要先打包，把你需要获取签名的包安装到手机上，然后安装签名获取工具打开输入包名

<h4 class="md-end-block md-heading md-focus">ios支付</h4>
要先创建一个uni-app 账号开通云服务空间和开通前端网页托管

在添加域名时报---设置一个三级域名就好
