Apache HttpClient 4.0-beta2 httppost,如何添加一个referer？

Question

我正在尝试将一个引用添加到Apache HttpClient(httpclient-4.0-beta2)中的http帖子.

我发现了一些示例代码.代码有效,但我想知道是否有一种更简单,更直接的方式来添加引用,而不是使用(不名称)addRequestInterceptor,它似乎将(yikes!)内部类作为参数.

有问题的代码从下面开始"//添加referer标题".我是新手,这段代码正在做一些我不理解的事情.这真的是在我的http帖子中添加引用者的最简单方法吗？

谢谢你的任何指示.

// initialize request parameters
List<NameValuePair> formparams = new ArrayList<NameValuePair>();
formparams.add(new BasicNameValuePair("firstName", "John"));
formparams.add(new BasicNameValuePair("lastName", "Doe"));

// set up httppost
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "UTF-8");
HttpPost httppost = new HttpPost(submitUrl);
httppost.setEntity(entity);

// create httpclient
DefaultHttpClient httpclient = new DefaultHttpClient();

// add the referer header, is an inner class used here?
httpclient.addRequestInterceptor(new HttpRequestInterceptor()
{   
    public void process(final HttpRequest request, 
                        final HttpContext context) throws HttpException, IOException
    {
        request.addHeader("Referer", referer);
    }
});

// execute the request
HttpResponse response = httpclient.execute(httppost);

Answer 1

任何理由不这样做:

httppost.addHeader("Referer", referer);

？HttpPost子类(间接)AbstractHttpMessage所以你应该只能添加标题.
