做网站费用多少百度联盟怎么做网站加入
前言
支付宝api的sdk没有提供go版，这里自己封装了一个go版的sdk，有需要的朋友可以自取使用
支付宝 AliPay SDK for Go, 集成简单，功能完善，持续更新，支持公钥证书和普通公钥进行签名和验签。
安装
go get github.com/abc-kaka/alipay
使用demo
package mainimport ("fmt""github.com/abc-kaka/alipay/open/pay/request""github.com/abc-kaka/alipay/open/pay/response""github.com/abc-kaka/alipay"
)func main() {// 支付宝应用私钥示例privateKey := "-----BEGIN RSA PRIVATE KEY-----

}项目目录结构说明
| 目录 | 说明 |
|---|---|
| common | 通用工具目录 |
| mini | 小程序api的请求参数、请求结果结构体 |
| open | 开放api的请求参数、请求结果结构体，包含人员、支付 |
| client.go | 客户端 |
| config.go | 配置 |
| route.go | api路由文件 |
项目扩展
可以看到目前的接口并不全，我这边只同步了部分接口，但扩展其实也很简单，只需要去支付宝官网把api接口的请求参数、请求结果copy到本项目，再添加对应的路由即可。
添加支付接口示例
支付宝支付接口

请求参数
创建请求参数文件：open/pay/request/alipay_trade_pay_request.go
package requestimport "encoding/json"type AlipayTradePayRequest struct {NotifyUrl stringBizContent AlipayTradePayBizContent
}// 普通预授权冻结押金转支付接口说明：https://opendocs.alipay.com/open/02cdx8?scene=34&pathHash=dd2813f3
type AlipayTradePayBizContent struct {OutTradeNo string `json:"out_trade_no,omitempty"`TotalAmount float64 `json:"total_amount,omitempty"`Subject string `json:"subject,omitempty"`ProductCode string `json:"product_code,omitempty"`AuthNo string `json:"auth_no,omitempty"`AuthConfirmMode string `json:"auth_confirm_mode,omitempty"`ExtendParams map[string]interface{} `json:"extend_params,omitempty"`BusinessParams map[string]interface{} `json:"business_params,omitempty"`// 直付通参数BuyerId string `json:"buyer_id,omitempty"` // 用户支付宝uidSellerId string `json:"seller_id,omitempty"` // 卖家支付宝uidSubMerchant map[string]interface{} `json:"sub_merchant,omitempty"` // 二级商户信息SettleInfo map[string]interface{} `json:"settle_info,omitempty"` // 结算详细信息
}// ToMap 转map
func (r *AlipayTradePayRequest) ToMap(v any) map[string]string {bizContent, _ := json.Marshal(r.BizContent)return map[string]string{"notify_url": r.NotifyUrl,"biz_content": string(bizContent),}
}请求结果
创建文件：open/pay/response/alipay_trade_create_response.go
package response// AlipayTradeCreateResponse (统一收单交易创建接口)-响应
type AlipayTradeCreateResponse struct {Code string `json:"code"`Msg string `json:"msg"`OutTradeNo string `json:"out_trade_no,omitempty"`TradeNo string `json:"trade_no,omitempty"`
}添加api接口
文件：router_open_pay.go
package alipayimport ("github.com/abc-kaka/alipay/open/pay/request""github.com/abc-kaka/alipay/open/pay/response"
)// OpenPayRouter H5&移动APP - 支付产品 - 路由
type OpenPayRouter struct {client Client
}// NewOpenPayRouter 创建H5&移动APP - 支付产品 - 路由
func NewOpenPayRouter(client Client) *OpenPayRouter {return &OpenPayRouter{client: client}
}// AlipayTradeCreate 统一收单交易创建接口
// https://opendocs.alipay.com/mini/6039ed0c_alipay.trade.create?pathHash=779dc517&ref=api&scene=de4d6a1e0c6e423b9eefa7c3a6dcb7a5
func (r *OpenPayRouter) AlipayTradeCreate(request request.AlipayTradeCreateRequest, response *response.AlipayTradeCreateResponse) (reqData map[string]interface{}, err error) {reqData, err = r.client.Exec("alipay.trade.create", &request, response)return
}绑定到路由上
文件：route.go
package alipaytype Route struct {Open *OpenRoute
}type OpenRoute struct {Pay *OpenPayRouter
}func NewRoute(client Client) *Route {return &Route{Open: &OpenRoute{Pay: NewOpenPayRouter(client),},}
} 恭喜你，完成接口的添加！
