在springboot项目中接入支付宝支付
- 一、在官网申请开通
- 二、编写代码
一、在官网申请开通
进入支付宝开放平台
支付宝扫码登录注册,填写相关信息。
因为我们是开发者,所以支付宝给我们提供一个完整的沙箱环境,只要登录开放平台就会给我们提供一个测试的商家账号和支付账号。
这里需设置下开发者的密钥我们选择系统默认,第一个点击启用即可
设置好之后,点击查看。
可以看见沙箱环境下有商家信息和买家信息
二、编写代码
将下面的代码复制到你的系统即可。注意:将里面的信息改成你自己的哦!
0、引入jar
<dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>3.0.0</version>
</dependency>

vue前端代码调用接口
// 点击挂号按钮调用
register(doctorId) {this.$http.post(`/ih/patient/diagnose/register/quick?doctorId=${doctorId}`).then((res) => {if (res.status == 200) {// 支付this.alipay(res.data.registerId);}});},
// 调用支付接口
alipay(registerId){this.$http.post(`/ih/diagnose/pay/alipay?registerId=${registerId}&isAppoint=false`).then((res) => {document.querySelector("body").innerHTML = res.data; // 查找到当前页面的body,将后台返回的form替换掉他的内容document.forms[0].submit(); // 执行submit表单提交,让页面重定向,跳转到支付宝页面});},
这样就在页面看跳转到了支付界面,支付成功之后就会返回到你指定的页面。
