uni-app中微信支付之微信公众号支付的实现【下】
相信大家已在网上找了各种资料，也看过了各种文档，对于整个流程我就不再重复啦，有疑惑的小伙伴可以移步微信开放平台查看详情，网页地址：https://pay.weixin.qq.com/wiki/doc/api/external/jsapi.php?chapter=2_2
废话不多说，直接上代码：
uni-app前端代码：
{{ vipName }}
￥{{ price }}
我这里后端使用的SpringBoot，Maven项目，代码如下：
com.github.binarywang
weixin-java-mp
2.7.0
com.github.binarywang
weixin-java-pay
3.0.0
在application.properties中配置相关信息
微信APP支付这块是需要证书，大家自行去微信开放平台配置下载后放入resources目录下，可直接用classpath:xxxxxx.p12引入
#微信支付
wx.pay.appId=XXXXXXXXXXXXXXXXXXXXX
wx.pay.appSecret=XXXXXXXXXXXXXXXXXXXXX
wx.pay.mchId=XXXXXXXXXXXXXXXXXXXXX
wx.pay.mchKey=XXXXXXXXXXXXXXXXXXXXX
wx.pay.keyPath=classpath:apiclient_cert.p12
wx.pay.tradeType=XXXXXXXXXXX
#微信公众号
wx.mp.appId=XXXXXXXXXXXXXXXXXXXXX
wx.mp.appSecret=XXXXXXXXXXXXXXXXXXXXX需要先获得用户授权，后端拿到openId存入session中，待调起支付时再从session中获取openId
let openId=uni.getStorageSync('openId');
if(openId){
//若有openId直接进行下一步操作
uni.navigateTo({
url: '../member/membercenter'
});
}else{
//若没有openId就请求后端授权
window.location.href = getApp().globalData.BaseUrl + "/thirdPartLogin/jswx/wxlogin?state=1";
return;
}在配置文件内添加以下内容：
#你的前端接受地址
wx.mp.oauth2RdmUri=https://XXXXXXXXXXXXXXXXXXXXXXX创建控制层
