Golang实现支付宝沙箱支付的方法步骤

func main() {
    r := gin.Default()
    r.GET("/pay", tools.WebPageAlipay)
    r.GET("/return", tools.AliPayNotify)
    r.Run(":8100")
}

var (
    appID = "你的支付宝ID"
    privateKey = "你的支付宝私钥"
    client, _  = alipay.New(appID, privateKey, false)
)
 
func init() {
    client.LoadAliPayPublicKey("你的支付宝公钥")
}

// WebPageAlipay 网页扫码支付
func WebPageAlipay(c *gin.Context) {
    ......
    var p = alipay.TradePagePay{}
    p.ReturnURL = "http://127.0.0.1:8080/return" //订单付款后跳转的网址页面
    p.Subject = fmt.Sprintf("订单号：%s", orderSn) //付款标题
    p.OutTradeNo = orderSn                     //商家订单号
    p.TotalAmount = price                      //价格
    p.ProductCode = "FAST_INSTANT_TRADE_PAY"
    
    var url, err = client.TradePagePay(p)
    if err != nil {
        fmt.Println(err)
    }
 
    var payURL = url.String() //扫码支付的网页链接，返回前端后打开
}

// AliPayNotify 接受通知接口
func AliPayNotify(c *gin.Context) {
    //获取url并转成*URL
    x, _ := url.Parse(c.Request.URL.String())
    //验证是否成功支付
    ok, err := client.VerifySign(x.Query())
}
