100使用Jetty9繼續使用Jersey2 + +

Question

我看到我的球衣+碼頭服務器在請求傳遞到我的處理程序之前響應100個繼續標題。我不想發送100-Continue，而是根據請求的URI/Headers發送3xx響應。

這是類org.glassfish.jersey.servlet.WebComponent該調用到request.getInputStream（）

public Value<Integer> service(
     final URI baseUri, 
     final URI requestUri, 
     final HttpServletRequest servletRequest, 
     final HttpServletResponse servletResponse) throws ServletException, IOException { 

    ContainerRequest requestContext = new ContainerRequest(baseUri, requestUri, 
      servletRequest.getMethod(), getSecurityContext(servletRequest), new ServletPropertiesDelegate(servletRequest)); 
    requestContext.setEntityStream(servletRequest.getInputStream()); 
    addRequestHeaders(servletRequest, requestContext); 

和碼頭髮送100繼續報頭時對請求的輸入流被要求。從org.eclipse.jetty.server.Request

@Override 
public ServletInputStream getInputStream() throws IOException 
{ 
    if (_inputState != __NONE && _inputState != _STREAM) 
     throw new IllegalStateException("READER"); 
    _inputState = _STREAM; 

    if (_channel.isExpecting100Continue()) 
     _channel.continue100(_input.available()); 

    return _input; 
} 

它調用到的HTTPChannel發送100繼續頭

/** 
* If the associated response has the Expect header set to 100 Continue, 
* then accessing the input stream indicates that the handler/servlet 
* is ready for the request body and thus a 100 Continue response is sent. 
* 
* @throws IOException if the InputStream cannot be created 
*/ 
public void continue100(int available) throws IOException 
{ 
    // If the client is expecting 100 CONTINUE, then send it now. 
    // TODO: consider using an AtomicBoolean ? 
    if (isExpecting100Continue()) 
    { 
     _expect100Continue = false; 

     // is content missing? 
     if (available == 0) 
     { 
      if (_response.isCommitted()) 
       throw new IOException("Committed before 100 Continues"); 

      // TODO: break this dependency with HttpGenerator 
      boolean committed = sendResponse(HttpGenerator.CONTINUE_100_INFO, null, false); 
      if (!committed) 
       throw new IOException("Concurrent commit while trying to send 100-Continue"); 
     } 
    } 
} 

如何防止球衣+碼頭從發回100繼續進行，請求到達澤西島標記的URI路徑方法？

Answer 1

隨着Expect: 100-Continue處理..

如果你想回應請求的那部分，然後：

• 不要試圖訪問請求參數（這需要讀取輸入流處理所有可能的參數源）
• 不要嘗試訪問請求輸入流（這意味着您正在接受100-Continue期望值並準備好接收實際的請求正文內容）
• 不要嘗試訪問請求閱讀器（這也會打開請求輸入流）
• 不要嘗試使用servlet異步I/O層（這會打開請求輸入流和響應輸出流）
• 請使用HttpServletResponse發送您的備用狀態代碼和/或響應主體內容。

這是所有標準的Servlet/Jetty行爲。
