Convert python code to Go for json encoding

问题

我已经翻译了你提供的代码段，如下所示：

  1. import json
  2. import time
  3. import hmac
  4. import hashlib
  5. import requests
  7. secret = "somekey"
  8. url = f"https://api.coindcx.com/exchange/v1/orders/status"
  9. timeStamp = int(round(time.time() * 1000))
  10. body = {
  11.     "id": "ead19992-43fd-11e8-b027-bb815bcb14ed",
  12.     "timestamp": timeStamp
  13. }
  14. json_body = json.dumps(body, separators=(',', ':'))
  15. signature = hmac.new(secret.encode('utf-8'), json_body.encode('utf-8'), hashlib.sha256).hexdigest()
  16. print(signature)
  17. headers = {
  18.     'Content-Type': 'application/json',
  19.     'X-AUTH-APIKEY': "someapikey",
  20.     'X-AUTH-SIGNATURE': signature
  21. }
  22. response = requests.post(url, data=json_body, headers=headers)
  23. print(response)

在Go语言中，你可以这样编写代码：

  1. import (
  2. 	"encoding/json"
  3. 	"fmt"
  4. 	"time"
  5. 	"crypto/hmac"
  6. 	"crypto/sha256"
  7. 	"encoding/hex"
  8. 	"net/http"
  9. 	"bytes"
  10. )
  12. type GetOrderStatusInput struct {
  13. 	ID        string `json:"id"`
  14. 	Timestamp int64  `json:"timestamp"`
  15. }
  17. func main() {
  18. 	secret := "somekey"
  19. 	url := "https://api.coindcx.com/exchange/v1/orders/status"
  20. 	timeStamp := time.Now().UnixNano() / 1000000
  21. 	getOrderStatusInput := GetOrderStatusInput{
  22. 		ID:        "ead19992-43fd-11e8-b027-bb815bcb14ed",
  23. 		Timestamp: timeStamp,
  24. 	}
  26. 	jsonBody, err := json.Marshal(getOrderStatusInput)
  27. 	if err != nil {
  28. 		fmt.Println("Error encoding JSON:", err)
  29. 		return
  30. 	}
  32. 	signature := generateSignature(secret, jsonBody)
  33. 	fmt.Println(signature)
  35. 	req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonBody))
  36. 	if err != nil {
  37. 		fmt.Println("Error creating request:", err)
  38. 		return
  39. 	}
  41. 	req.Header.Set("Content-Type", "application/json")
  42. 	req.Header.Set("X-AUTH-APIKEY", "someapikey")
  43. 	req.Header.Set("X-AUTH-SIGNATURE", signature)
  45. 	client := &http.Client{}
  46. 	resp, err := client.Do(req)
  47. 	if err != nil {
  48. 		fmt.Println("Error sending request:", err)
  49. 		return
  50. 	}
  51. 	defer resp.Body.Close()
  53. 	fmt.Println(resp)
  54. }
  56. func generateSignature(secret string, data []byte) string {
  57. 	h := hmac.New(sha256.New, []byte(secret))
  58. 	h.Write(data)
  59. 	signature := hex.EncodeToString(h.Sum(nil))
  60. 	return signature
  61. }

I have written this python code -

  1. import json
  2. import time
  3. import hmac
  4. import hashlib
  5. import requests
  6. secret = "somekey"
  7. url = f"https://api.coindcx.com/exchange/v1/orders/status"
  8. timeStamp = int(round(time.time() * 1000))
  9. body = {
  10. "id": "ead19992-43fd-11e8-b027-bb815bcb14ed",
  11. "timestamp": timeStamp
  12. }
  13. json_body = json.dumps(body, separators=(',', ':'))
  14. signature = hmac.new(secret.encode('utf-8'), json_body.encode('utf-8'), hashlib.sha256).hexdigest()
  15. print(signature)
  16. headers = {
  17. 'Content-Type': 'application/json',
  18. 'X-AUTH-APIKEY': "someapikey",
  19. 'X-AUTH-SIGNATURE': signature
  20. }
  21. response = requests.post(url, data=json_body, headers=headers)
  22. print(response)

In Go I tried writing it like this -

  1. type GetOrderStatusInput struct { 	
  2. ID string `json:"id"`
  3. Timestamp int64  `json:"timestamp"` 
  4. }
  5. timestamp := time.Now().UnixNano() / 1000000 
  6. getOrderStatusInput := GetOrderStatusInput{ 
  7. ID: "ead19992-43fd-11e8-b027-bb815bcb14ed", 		
  8. Timestamp: timestamp, 	
  9. }

But not able to figure out how to do json encoding and hmac here.

得分: 1

  1. package main
  3. import (
  4. 	"bytes"
  5. 	"crypto/hmac"
  6. 	"crypto/sha256"
  7. 	"encoding/json"
  8. 	"fmt"
  9. 	"io/ioutil"
  10. 	"net/http"
  11. 	"time"
  12. )
  14. func main() {
  15. 	secret := "somekey"
  16. 	url := "https://api.coindcx.com/exchange/v1/orders/status"
  17. 	type GetOrderStatusInput struct {
  18. 		ID        string `json:"id"`
  19. 		Timestamp int64  `json:"timestamp"`
  20. 	}
  22. 	timestamp := time.Now().UnixNano() / 1000000
  23. 	getOrderStatusInput := GetOrderStatusInput{
  24. 		ID:        "ead19992-43fd-11e8-b027-bb815bcb14ed",
  25. 		Timestamp: timestamp,
  26. 	}
  27. 	jsonBytes, err := json.Marshal(getOrderStatusInput)
  28. 	if err != nil {
  29. 		// 处理错误
  30. 	}
  32. 	mac := hmac.New(sha256.New, []byte(secret))
  33. 	mac.Write(jsonBytes)
  34. 	signature := mac.Sum(nil)
  36. 	jsonBody := bytes.NewReader(jsonBytes)
  38. 	req, _ := http.NewRequest("POST", url, jsonBody)
  39. 	req.Header.Set("Content-Type", "application/json")
  40. 	req.Header.Set("X-AUTH-APIKEY", "someapikey")
  41. 	req.Header.Set("X-AUTH-SIGNATURE", string(signature))
  43. 	client := &http.Client{}
  44. 	resp, err := client.Do(req)
  45. 	if err != nil {
  46. 		// 处理错误
  47. 	}
  48. 	defer resp.Body.Close()
  50. 	body, err := ioutil.ReadAll(resp.Body)
  51. 	if err != nil {
  52. 		// 处理错误
  53. 	}
  55. 	fmt.Println(string(body))
  56. }

以上是给定的Go语言代码的翻译。

英文: 
  1. package main
  2. import (
  3. "bytes"
  4. "crypto/hmac"
  5. "crypto/sha256"
  6. "encoding/json"
  7. "fmt"
  8. "io/ioutil"
  9. "net/http"
  10. "time"
  11. )
  12. func main() {
  13. secret := "somekey"
  14. url := "https://api.coindcx.com/exchange/v1/orders/status"
  15. type GetOrderStatusInput struct {
  16. ID        string `json:"id"`
  17. Timestamp int64  `json:"timestamp"`
  18. }
  19. timestamp := time.Now().UnixNano() / 1000000
  20. getOrderStatusInput := GetOrderStatusInput{
  21. ID:        "ead19992-43fd-11e8-b027-bb815bcb14ed",
  22. Timestamp: timestamp,
  23. }
  24. jsonBytes, err := json.Marshal(getOrderStatusInput)
  25. if err != nil {
  26. // handle error
  27. }
  28. mac := hmac.New(sha256.New, []byte(secret))
  29. mac.Write(jsonBytes)
  30. signature := mac.Sum(nil)
  31. jsonBody := bytes.NewReader(jsonBytes)
  32. req, _ := http.NewRequest("POST", url, jsonBody)
  33. req.Header.Set("Content-Type", "application/json")
  34. req.Header.Set("X-AUTH-APIKEY", "someapikey")
  35. req.Header.Set("X-AUTH-SIGNATURE", string(signature))
  36. client := &http.Client{}
  37. resp, err := client.Do(req)
  38. if err != nil {
  39. // handle error
  40. }
  41. defer resp.Body.Close()
  42. body, err := ioutil.ReadAll(resp.Body)
  43. if err != nil {
  44. // handle error
  45. }
  46. fmt.Println(string(body))
  47. }
