HP ALM Rest API QCSession 411身份驗證

Question

我正在使用HP-ALM 12.01，它似乎充滿了問題。我目前無法更新到其他版本。

我想要訪問其餘api從JUnit自動上傳測試結果。我正在使用顯示here（示例應用程序 - > Infrastructure）的基礎結構。從中，我的連接腳本將base64編碼的登錄信息傳遞給authentication-point/authenticate，並且我正在檢索有效的LWSSO cookie。但是，當我使用此cookie連接到rest/site-session以接收我的QCSession cookie時，我收到了411長度要求錯誤。我試圖將Content-Length硬編碼到標頭中，如下所示

public void GetQCSession(){ 
    String qcsessionurl = con.buildUrl("rest/site-session"); 
    Map<String, String> requestHeaders = new HashMap<String, String>(); 
    requestHeaders.put("Content-Type", "application/xml"); 
    requestHeaders.put("Accept", "application/xml"); 
    requestHeaders.put("Content-Length", "0"); 
    try { 
     Response resp = con.httpPost(qcsessionurl, null, requestHeaders); 
     con.updateCookies(resp); 
     System.out.println(resp.getStatusCode()); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

這沒有奏效。我也嘗試修改基礎結構以自動注入內容長度標題，如下所示

private void prepareHttpRequest(
     HttpURLConnection con, 
     Map<String, String> headers, 
     byte[] bytes, 
     String cookieString) throws IOException { 

    String contentType = null; 

    //attach cookie information if such exists 
    if ((cookieString != null) && !cookieString.isEmpty()) { 

     con.setRequestProperty("Cookie", cookieString); 
    } 

    //send data from headers 
    if (headers != null) { 

     //Skip the content-type header - should only be sent 
     //if you actually have any content to send. see below. 
     contentType = headers.remove("Content-Type"); 

     Iterator<Entry<String, String>> 
       headersIterator = headers.entrySet().iterator(); 
     while (headersIterator.hasNext()) { 
      Entry<String, String> header = headersIterator.next(); 
      con.setRequestProperty(header.getKey(), header.getValue()); 
     } 
    } 

    // If there's data to attach to the request, it's handled here. 
    // Note that if data exists, we take into account previously removed 
    // content-type. 
    if ((bytes != null) && (bytes.length > 0)) { 

     con.setDoOutput(true); 

     //warning: if you add content-type header then you MUST send 
     // information or receive error. 
     //so only do so if you're writing information... 
     if (contentType != null) { 
      con.setRequestProperty("Content-Type", contentType); 
     } 

     OutputStream out = con.getOutputStream(); 
     out.write(bytes); 
     out.flush(); 
     out.close(); 
     con.setRequestProperty("Content-Length", Integer.toString(bytes.length)); 
    } else { 
     con.setRequestProperty("Content-Length", "0"); 
    } 
} 

這也不起作用。 請注意，setRequestProperty只是一個.set（鍵，值）到MessageHeader

有沒有人處理過這個問題或知道如何解決它？

請注意，郵遞員不會發生這些問題。所有4個Cookie都是在網站會話後生成的。

問題是Java的HttpURLConnection手動設置時會忽略某些屬性。其中之一是內容長度。這是因爲它會自動設置它自己。但是，如果你沒有發送任何數據，它只是不發送它，由於它過時的http協議，ALM不接受，因爲它預計會收到一個內容長度爲0.

要解決這個問題，你必須告訴java允許重寫的標題。這是通過運行

System.setProperty("sun.net.http.allowRestrictedHeaders", "true"); 

更多信息完成，看這裏Why does Content-Length HTTP header field use a value other than the one given in Java code?
