Golang封装微信支付接口

自己花了点时间把微信支付接口用golang封装了一下,以便以后需要接微信支付的时候可以直接拿来用。之前在网上看了很多写得NB微信SDK,自己也想尝试一下,于是做了api的简单封装。

package main
import (
 "fmt"
 dev "github.com/hong008/wechat-sdk"
)
func main() {
 var appId, mchId, apiKey, apiSecret string
 client := dev.NewPayer(dev.WithAppId(appId), dev.WithMchId(mchId), dev.WithApiKey(apiKey), dev.WithSecret(apiSecret))
 //unified order
 param := dev.NewParam()
 param.Add("nonce_str", "yourNonceStr")
 param.Add("body", "yourBody")
 param.Add("out_trade_no", "yourOutTradeNo")
 param.Add("total_fee", 1)
 param.Add("spbill_create_ip", "yourIp")
 param.Add("notify_url", "yourUrl")
 param.Add("trade_type", "JSAPI")
 result, err := client.UnifiedOrder(param)
 if err != nil {
 handleErr(err)
 }
 appId, _ := result.GetString("apppid")
 prepayId, _ := result.GetString("prepay_id")
 param = dev.NewParam()
 param.Add("appId", appId)
 param.Add("timeStamp", time.Now().Unix())
 param.Add("nonceStr", "nonceStr")
 param.Add("package", "prepay_id="+prepayId)
 param.Add("signType", "MD5")
 //use to evoke wechat pay 
 sign := param.Sign("MD5")
 //download bill
 param = dev.NewParam()
 param.Add("nonce_str", "yourNonceStr")
 param.Add("bill_date", "yourDate")
 param.Add("bill_type", "ALL")
 param.Add("tar_type", "GZIP")
 err := client.DownloadBill(param, "./bill")
 if err != nil {
 handleErr(err)
 }
 
 //get phone for mini program user
 result, err := client.GetUserPhoneForMini("code", "encryptedData", "iv")
 if err != nil {
 handleErr(err)
 }
 var phone string
 if countryCode := result.Get("countryCode"); countryCode != nil && countryCode.(string) == "86" {
 purePhone := result.Get("purePhoneNumber")
 phone = purePhone.(string)
 } else {
 phoneNumber := result.Get("phoneNumber")
 phone = phoneNumber.(string)
 }
 fmt.Printf("user phone is %s\n", phone)
}

package main
import (
 "fmt"
 "net/http"
 
 dev "github.com/hong008/wechat-sdk"
)
func main() {
 var appId, mchId, apiKey, apiSecret string
 client := dev.NewPayer(dev.WithAppId(appId), dev.WithMchId(mchId), dev.WithApiKey(apiKey), dev.WithSecret(apiSecret))
 //handle refund notify
 http.HandleFunc("/refund_notify", func(writer http.ResponseWriter, request *http.Request) {
 defer request.Body.Close()
 result, err := client.RefundNotify(request.Body)
 if err != nil {
 handleErr(err)
 }
 fmt.Printf("RefundNotify Result = %v\n", result.Data())
 })
 http.ListenAndServe(":8810", nil)
}
