Apache HttpClient 4.0-beta2 httppost, how to add a referer?
提问by Lasoldo Solsifa
I'm trying to add a referer to an http post in Apache HttpClient (httpclient-4.0-beta2).
我正在尝试向 Apache HttpClient (httpclient-4.0-beta2) 中的 http 帖子添加引用。
I found some sample code that does this. The code works, but I'm wondering if there is not a simpler, more straightforward way to add the referer than using the (ominously named) addRequestInterceptor, which appears to take an (yikes!) inner class as a parameter.
我找到了一些执行此操作的示例代码。代码有效，但我想知道是否没有比使用（不祥的名称）addRequestInterceptor 更简单、更直接的方法来添加引用，它似乎采用（哎呀！）内部类作为参数。
The code in question begins below with "// add the referer header". I'm a novice, and this code is doing several things that I don't understand. Is this really the simplest way to add a referer to my http post?
有问题的代码以“// 添加引用标头”开头。我是新手，这段代码做了几件我不明白的事情。这真的是向我的 http 帖子添加引用的最简单方法吗？
Thanks for any pointers.
感谢您的指点。
// 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);

Any reason not to do:
任何不这样做的理由：
httppost.addHeader("Referer", referer);
? HttpPostsubclasses (indirectly) AbstractHttpMessageso you should be able to just add headers that way.
? HttpPost子类（间接），AbstractHttpMessage因此您应该能够以这种方式添加标题。
