我一直想从我的 go 微服务向 Rapyd API 执行一个简单的 POST 请求。 我在网上搜索了很多解决方案，但没有一个奏效... 如果我尝试发出请求，我会收到 400 Bad Request 或包含“Network unreachable”的错误 我尝试使用 Go 结构制作正文有效负载，使用字符串中的 JSON，但似乎没有任何效果，这是我的代码：（抱歉，我不得不插入带有代码段的结构，因为它不适用于代码示例）
type CardRequest struct {
Amount float64 `json:"amount"`
Currency string `json:"currency"`
PaymentMethod PaymentMethod `json:"payment_method"`
ErrorPaymentURL string `json:"error_payment_url"`
Capture bool `json:"capture"`
}
type PaymentMethod struct {
Type string `json:"type"`
Fields Fields `json:"fields"`
}
type Fields struct {
Number string `json:"number"`
ExpirationMonth string `json:"expiration_month"`
ExpirationYear string `json:"expiration_year"`
Cvv string `json:"cvv"`
} hc := http.Client{}
form, _ := json.Marshal(CardRequest{
Amount: 53.5,
Currency: "THB",
PaymentMethod: PaymentMethod{
Type: "th_visa_card",
Fields: Fields{
Number: "4111111111111111",
ExpirationMonth: "10",
ExpirationYear: "21",
Cvv: "123",
},
},
ErrorPaymentURL: "https://error_example.net",
Capture: true})
http_method := "post"
url_path := "/v1/payments"
salt := strconv.Itoa(10000000 + rand.Intn(99999999-10000000))
timestamp := strconv.Itoa(int(time.Now().Unix()))
access_key := "my_access_key"
secret_key := "my_secret_key"
sign_str := http_method + url_path + salt + timestamp + access_key + secret_key + string(form[:])
fmt.Println(form)
h := hmac.New(sha256.New, []byte(secret_key))
h.Write([]byte(sign_str))
buf := h.Sum(nil)
signature := base64.RawURLEncoding.EncodeToString(buf)
httpReq, err := http.NewRequest("POST", "https://sandboxapi.rapyd.net/v1/payments", bytes.NewBuffer(form))
// req.PostForm = form
httpReq.Header.Set("Content-Type", "application/json")
httpReq.Header.Set("access_key", access_key)
httpReq.Header.Set("salt", salt)
httpReq.Header.Set("signature", signature)
httpReq.Header.Set("timestamp", timestamp)
resp, err := hc.Do(httpReq)
if err != nil {
fmt.Println(err)
return errors.New(fmt.Sprintf("payment request failed... %v", err))
}
bytes, err := httputil.DumpRequest(httpReq, true)
if err != nil {
fmt.Println(err)
}
fmt.Println(string(bytes))
data, err2 := io.ReadAll(resp.Body)
if err2 != nil {
fmt.Println(err2)
return errors.New(fmt.Sprintf("payment body lecture failed... %v", err2))
}
fmt.Println(string(data))
resp.Body.Close()
// if data.status != "SUCCESS" || data.data.status != "CLO" || data.data.amount != req.Order.Total {
// return errors.New(fmt.Sprintf("payment failed... %v", data.status.message))
// }
非常感谢您阅读我，我不知道该怎么办... 不要犹豫，向我询问更多信息，如果我的英语不好，请见谅！
