javascript - 为什么浏览器从 vibed 得到响应这么慢？

Question

我正在从浏览器向 vibed 发送数据。在 vibed 控制台上，我立即收到请求。但是在浏览器控制台中，我需要两次等待 console.log 5-8 秒。而且我不明白问题出在哪里。

     postQuestionsContent : function()
     {
        this.$http.post('http://127.0.0.1:8080/questions', JSON.stringify(this.questions)).then(function(response)
        {
           console.log("Server response: ", response.status); // 5-8 seconds here

        }, function(response)
          {
            console.log("Server report that it can't process request");
          }
        ); 
      }

和D代码:

void getQuestions(HTTPServerRequest req, HTTPServerResponse res)
{

    if (req.session)
    {   
       Json questions;
       try
       {
        questions = req.json;
        writeln("We got questions content!");
        res.statusCode = 200;
       }
       catch (Exception e)
       {
        writeln("Can't parse incoming data as JSON");
        writeln(e.msg);
        writeln("------------------------------------------");
       }
    }

    else
    {
        res.statusCode = 401;
    }

   res.writeVoidBody;
}

你读过文档吗？

https://vibed.org/api/vibe.http.server/HTTPServerResponse.writeVoidBody

他们在那里说:

For an empty body, just use writeBody, as this method causes problems with some keep-alive connections.

所以也许你应该尝试使用
