How to implement Alipay sandbox payment in Golang

First of all, I use gin as my backend framework, and we set up several interfaces first.

func main() {
    r := ()
    ("/pay", )
    ("/return", )
    (":8100")
}

/smartwalle/alipay This third-party library defines many Alipay interfaces. We directly use this library to continue our development.

Initialize first

var (
    appID = "Your Alipay ID"
    privateKey = "Your Alipay Private Key"
    client, _  = (appID, privateKey, false)
)
 
func init() {
    ("Your Alipay Public Key")
}

Fill in the corresponding location of the key and public key applied in the Alipay open platform sandbox

Use the Web Scan code to pay the payment interface

// WebPageAlipay Scan the QR code to payfunc WebPageAlipay(c *) {
    ......
    var p = {}
     = "http://127.0.0.1:8080/return" //The URL page that jumps after order payment     = ("Order number: %s", orderSn) //Payment title     = orderSn                     // Merchant Order Number     = price                      //price     = "FAST_INSTANT_TRADE_PAY"
    
    var url, err = (p)
    if err != nil {
        (err)
    }
 
    var payURL = () //Scan the QR code to pay the web page link, and then open after returning to the front end}

After the payment is successful, the payment page will automatically jump to the address set in (the front-end address I set here. After jumping to the front-end address, the front-end requests /return from the back-end, completely obtains the page's query parameters and splices them all into the back-end /return), and the back-end obtains the query parameters for signature verification

// AliPay Notify Receive Notification Interfacefunc AliPayNotify(c *) {
    //Get the url and convert it to *URL    x, _ := (())
    //Verify whether the payment is successful    ok, err := (())
}
