PHP vs Golang http calls gets different results

问题

我正在尝试在Google App Engine Go中实现以下PHP代码：

  1. <?php
  3. function api_query(array $req = array()) {
  4.     $key = '90294318da0162b082c3d27126be80c3873955f9';
  6.     $req['method'] = 'getinfo';
  7.     $req['nonce'] = 1394503747386411;
  9.     // 生成POST数据字符串
  10.     $post_data = http_build_query($req, '', '&');
  11.     $sign = '75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348';
  13.     // 生成额外的头部信息
  14.     $headers = array(
  15.         'Sign: '.$sign,
  16.         'Key: '.$key,
  17.     );
  19.     // 初始化curl句柄
  20.     static $ch = null;
  21.     if (is_null($ch)) {
  22.         $ch = curl_init();
  23.         curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  24.         curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; Cryptsy API PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
  25.     }
  26.     curl_setopt($ch, CURLOPT_URL, 'https://api.cryptsy.com/api');
  27.     curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
  28.     curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  29.     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  31.     // 执行查询
  32.     $res = curl_exec($ch);
  34.     if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
  35.     $dec = json_decode($res, true);
  36.     if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
  38.     echo "<pre>".print_r($dec, true)."</pre>";
  39.     return $dec;
  40. }
  42. api_query();

执行该代码后，会返回一个JSON数组。我尝试在Golang中实现相同的代码：

  1. func PrivateCall(c appengine.Context) (map[string]interface{}, error) {
  2.     AuthAPI := "https://api.cryptsy.com/api"
  3.     APIKey := "90294318da0162b082c3d27126be80c3873955f9"
  4.     tr := urlfetch.Transport{Context: c}
  5.     values := url.Values{}
  6.     values.Set("method", "getinfo")
  7.     values.Set("nonce", "1394503747386411")
  9.     signature := "75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348"
  11.     req, err := http.NewRequest("POST", AuthAPI+"?"+values.Encode(), nil)
  12.     if err != nil {
  13.         c.Infof("API - Call - error 2 - %s", err.Error())
  14.         return nil, err
  15.     }
  16.     req.Header.Set("Key", APIKey)
  17.     req.Header.Set("Sign", signature)
  19.     c.Infof("req - %v", req)
  20.     resp, err := tr.RoundTrip(req)
  21.     if err != nil {
  22.         c.Errorf("API post error: %s", err)
  23.         return nil, err
  24.     }
  25.     defer resp.Body.Close()
  26.     // 读取响应
  27.     body, err := ioutil.ReadAll(resp.Body)
  28.     if err != nil {
  29.         c.Errorf("API read error: could not read body: %s", err)
  30.         return nil, err
  31.     }
  32.     result := make(map[string]interface{})
  33.     // 解析JSON响应
  34.     err = json.Unmarshal(body, &result)
  35.     if err != nil {
  36.         c.Infof("Unmarshal: %v", err)
  37.         c.Infof("%s", body)
  38.         return nil, err
  39.     }
  40.     return result, nil
  41. }

我收到一个错误消息，提示"无法授权请求-请检查您的POST数据"。有人能看出可能导致这个错误的原因吗？目前我最好的猜测是Go中的请求头是map[string][]string，而PHP中似乎是一个数组...

英文:

I am trying to implement the following PHP code in Google App Engine Go:

  1. &lt;?php
  2. function api_query(array $req = array()) {
  3. $key = &#39;90294318da0162b082c3d27126be80c3873955f9&#39;;
  4. $req[&#39;method&#39;] = &#39;getinfo&#39;;
  5. $req[&#39;nonce&#39;] = 1394503747386411;
  6. // generate the POST data string
  7. $post_data = http_build_query($req, &#39;&#39;, &#39;&amp;&#39;);
  8. $sign = &#39;75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348&#39;;
  9. // generate the extra headers
  10. $headers = array(
  11. &#39;Sign: &#39;.$sign,
  12. &#39;Key: &#39;.$key,
  13. );
  14. // our curl handle (initialize if required)
  15. static $ch = null;
  16. if (is_null($ch)) {
  17. $ch = curl_init();
  18. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  19. curl_setopt($ch, CURLOPT_USERAGENT, &#39;Mozilla/4.0 (compatible; Cryptsy API PHP client; &#39;.php_uname(&#39;s&#39;).&#39;; PHP/&#39;.phpversion().&#39;)&#39;);
  20. }
  21. curl_setopt($ch, CURLOPT_URL, &#39;https://api.cryptsy.com/api&#39;);
  22. curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
  23. curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  24. curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  25. // run the query
  26. $res = curl_exec($ch);
  27. if ($res === false) throw new Exception(&#39;Could not get reply: &#39;.curl_error($ch));
  28. $dec = json_decode($res, true);
  29. if (!$dec) throw new Exception(&#39;Invalid data received, please make sure connection is working and requested API exists&#39;);
  30. echo &quot;&lt;pre&gt;&quot;.print_r($dec, true).&quot;&lt;/pre&gt;&quot;;
  31. return $dec;
  32. }
  33. api_query();

When executed, the code returns a JSON array of values. I tried implementing the same code in Golang:

  1. func PrivateCall(c appengine.Context) (map[string]interface{}, error) {
  2. AuthAPI := &quot;https://api.cryptsy.com/api&quot;
  3. APIKey := &quot;90294318da0162b082c3d27126be80c3873955f9&quot;
  4. tr := urlfetch.Transport{Context: c}
  5. values := url.Values{}
  6. values.Set(&quot;method&quot;, &quot;getinfo&quot;)
  7. values.Set(&quot;nonce&quot;, &quot;1394503747386411&quot;)
  8. signature := &quot;75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348&quot;
  9. req, err := http.NewRequest(&quot;POST&quot;, AuthAPI+&quot;?&quot;+values.Encode(), nil)
  10. if err != nil {
  11. c.Infof(&quot;API - Call - error 2 - %s&quot;, err.Error())
  12. return nil, err
  13. }
  14. req.Header.Set(&quot;Key&quot;, APIKey)
  15. req.Header.Set(&quot;Sign&quot;, signature)
  16. c.Infof(&quot;req - %v&quot;, req)
  17. resp, err := tr.RoundTrip(req)
  18. if err != nil {
  19. c.Errorf(&quot;API post error: %s&quot;, err)
  20. return nil, err
  21. }
  22. defer resp.Body.Close()
  23. //reading response
  24. body, err := ioutil.ReadAll(resp.Body)
  25. if err != nil {
  26. c.Errorf(&quot;API read error: could not read body: %s&quot;, err)
  27. return nil, err
  28. }
  29. result := make(map[string]interface{})
  30. //unmarshalling JSON response
  31. err = json.Unmarshal(body, &amp;result)
  32. if err != nil {
  33. c.Infof(&quot;Unmarshal: %v&quot;, err)
  34. c.Infof(&quot;%s&quot;, body)
  35. return nil, err
  36. }
  37. return result, nil
  38. }

I am getting an error saying "Unable to Authorize Request - Check Your Post Data". Does anyone see what could've caused this error? At the moment my best guess is that perhaps the request header in Go is a map[string][]string, while in PHP it appears to be an array...

根据LeGEC的建议，你将POST数据放在URL的末尾，就像是一个GET请求。

尝试将以下代码替换为：

  1. data := struct {
  2.     method string
  3.     nonce  string
  4. }{
  5.     "getinfo",
  6.     "1394503747386411",
  7. }
  8. signature := "75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348"
  9. postData, err := json.Marshal(data)
  10. if err != nil {
  11.     return nil, err
  12. }
  13. buf := bytes.NewBuffer(postData)
  14. req, err := http.Post(AuthAPI, "application/json", buf)

这样做可以将数据作为JSON格式的请求体发送。

英文:

As suggested by LeGEC, you're putting the POST data onto the end of the URL as if it were a GET request.

Try replacing

  1. values := url.Values{}
  2. values.Set(&quot;method&quot;, &quot;getinfo&quot;)
  3. values.Set(&quot;nonce&quot;, &quot;1394503747386411&quot;)
  4. signature := &quot;75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348&quot;
  5. req, err := http.NewRequest(&quot;POST&quot;, AuthAPI+&quot;?&quot;+values.Encode(), nil)

with

  1. data := struct {
  2. method string
  3. nonce  string
  4. }{
  5. &quot;getinfo&quot;,
  6. &quot;1394503747386411&quot;,
  7. }
  8. signature := &quot;75da1e3ff750286bf73d03197f1b779fbfff963fd7402941ae326509a6615eacb839b44f236b4d5ee6cff39321e7b35e9563a9a2075e99df0f4ee3b732999348&quot;
  9. postData, err := json.Marshal(data)
  10. if err != nil {
  11. return nil, err
  12. }
  13. buf := bytes.NewBuffer(postData)
  14. req, err := http.Post(AuthAPI, &quot;application/json&quot;, buf)

这是你需要的内容，以及你错过的几个要点。

  • 在使用https时，需要设置TLSClientConfig。
  • 自定义头部缺少X-前缀。
  • values.Encode()的位置错误。

示例：请参考 https://www.cryptsy.com/pages/api

  1. var (
  2. 	urlStr = "https://api.cryptsy.com/api"
  3. 	key    = "YOUR KEY"
  4. 	secret = "YOUR SECRECT"
  5. 	agent  = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36"
  6. )
  8. func main() {
  10. 	client := &http.Client{Transport: &http.Transport{
  11. 		TLSClientConfig: &tls.Config{
  12. 			InsecureSkipVerify: true,
  13. 		},
  14. 	}}
  16. 	values := url.Values{}
  17. 	//  $req['method'] = $method;
  18. 	values.Set("method", "getinfo")
  20. 	// $mt = explode(' ', microtime());
  21. 	// $req['nonce'] = $mt[1];
  22. 	values.Set("nonce", time.Nanosecond.String())
  24. 	//  $post_data = http_build_query($req, '', '&');
  25. 	encoded := values.Encode()
  27. 	mac := hmac.New(sha512.New, []byte(secret))
  28. 	mac.Write([]byte(encoded))
  30. 	//$sign = hash_hmac("sha512", $post_data, $secret);
  31. 	sign := fmt.Sprintf("%x", mac.Sum(nil))
  33. 	req, err := http.NewRequest("POST", urlStr, bytes.NewBufferString(encoded))
  35. 	if err != nil {
  36. 		log.Fatalln(err)
  37. 	}
  39. 	// generate the extra headers
  40. 	// $headers = array(
  41. 	// 'Sign: '.$sign,
  42. 	// 'Key: '.$key,
  43. 	// );
  44. 	req.Header.Set("X-Sign", sign)
  45. 	req.Header.Set("X-Key", key)
  47. 	//  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; Cryptsy API PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
  48. 	req.Header.Set("User-Agent", agent)
  49. 	req.Header.Add("Content-Type", "application/x-www-form-urlencoded")
  50. 	req.Header.Add("Content-Length", strconv.Itoa(len(encoded)))
  52. 	//       $res = curl_exec($ch);
  53. 	resp, err := client.Do(req)
  55. 	if err != nil {
  56. 		log.Fatalln(err)
  57. 	}
  58. 	fmt.Println(resp.Status)
  60. 	data, _ := ioutil.ReadAll(resp.Body)
  61. 	fmt.Printf("%s", data)
  62. }
英文:

Here is what you need and here are the few things you missed.

  • When working with https you need to set the TLSClientConfig
  • Missing X- prefix in custom headers
  • values.Encode() is the the wrong position.

Example: See https://www.cryptsy.com/pages/api

  1. var (
  2. urlStr = &quot;https://api.cryptsy.com/api&quot;
  3. key    = &quot;YOUR KEY&quot;

  6. )
  7. func main() {
  8. client := &amp;http.Client{Transport: &amp;http.Transport{
  9. TLSClientConfig: &amp;tls.Config{
  10. InsecureSkipVerify: true,
  11. },
  12. }}
  13. values := url.Values{}
  14. //  $req[&#39;method&#39;] = $method;
  15. values.Set(&quot;method&quot;, &quot;getinfo&quot;)
  16. // $mt = explode(&#39; &#39;, microtime());
  17. // $req[&#39;nonce&#39;] = $mt[1];
  18. values.Set(&quot;nonce&quot;, time.Nanosecond.String())
  19. //  $post_data = http_build_query($req, &#39;&#39;, &#39;&amp;&#39;);
  20. encoded := values.Encode()
  21. mac := hmac.New(sha512.New, []byte(secret))
  22. mac.Write([]byte(encoded))
  23. //$sign = hash_hmac(&quot;sha512&quot;, $post_data, $secret);
  24. sign := fmt.Sprintf(&quot;%x&quot;, mac.Sum(nil))
  25. req, err := http.NewRequest(&quot;POST&quot;, urlStr, bytes.NewBufferString(encoded))
  26. if err != nil {
