Question

我正在尝试用我的Xpage读取由 out.writeBytes 创建的java生成的JSON流。我可以获取getServerPort和其他数据（在下面的代码中列出），但是当我尝试使用BufferedReader或ServletInputStream读取上下文时，我正在发现错误。任何人都知道在Xpage上读取流内容的简单方法吗？ readLine 方法返回null。

    var exCon = facesContext.getExternalContext()
    var httpRequest:javax.faces.contex.ExternalContext =exCon.getRequest();

    print("CallCenter getContext "+String(exCon.getContext()))
    print("CallCenter ContentType "+String(httpRequest.getContentType()))
    print("CallCenter ContentLength"+String(httpRequest.getContentLength()))        
    print("CallCenter RemoteAddr "+String(httpRequest.getRemoteAddr()       ))
    print("CallCenter ServerPort "+String(httpRequest.getServerPort()))

    facesContext.responseComplete();

        //  ONE OF METHODS I've TRIED =============
         var stringBuffer:java.lang.StringBuffer = new java.lang.StringBuffer(80);
         var line = null;                 
         var reader:java.io.BufferedReader = httpRequest.getReader();
         while ((line = reader.readLine()) != null)
          {
            stringBuffer.append(line);
            stringBuffer.append("\n");
          }       
             print("Buffer "+stringBuffer.toString());

           // ============================


    } catch(e) {

    _dump(e);

只能有一个：流或读者。而不是getReader（）使用新的InputStreamReader（in）;指向上下文的输入流

Xpage读取JSON上下文 - http POST请求
