HttpClient的重定向处理器 [英] Httpclient redirect handler

问题描述

我试图调用使用相对URL的Web服务器重定向的一些电话。这当然是不工作DefaultHttpClient因为它不把它当作一个相对URL。我尽可能实现RedirectHandler，企图搭上重定向，并添加在基本通话得到，但我不知道如何得到重定向的位置。

通过下面的方法我怎么去寻找在哪里我被重定向到？我找不到任何响应或上下文有什么，我需要的任何领域，我不知道还有什么地方看。

 公共URI getLocationURI（Htt的presponse响应，HttpContext的背景下）
 

解决方案

我的解决办法是阅读的位置标头和跟随他们。帮我：

 如果（状态code！= HttpStatus.SC_OK）{
    标题[]头= response.getHeaders（位置）;

    如果（头= NULL和放大器;！＆安培;！headers.length = 0）{
        字符串的newURL =标题[headers.length  -  1] .getValue（）;
        //再次调用相同的下载方法与新的URL
        返回downloadBitmap（的newURL）;
    } 其他 {
        返回null;
    }
}

I'm trying to call a web server that is using relative URL redirects for some of the calls. This of course isn't working with DefaultHttpClient as it isn't treating it as a relative URL. I've gotten as far as implementing a RedirectHandler in an attempt to catch the redirect and add in the base call but I can't work out how to get the location of the redirect.

With the following method how do I go about finding out where I am being redirected to? I can't find any fields on either response or context that have what I need and I don't know where else to look.

public URI getLocationURI(HttpResponse response, HttpContext context) 

解决方案

My solution is to read location headers and follow them. This helped me:

if (statusCode != HttpStatus.SC_OK) {
    Header[] headers = response.getHeaders("Location");

    if (headers != null && headers.length != 0) {
        String newUrl = headers[headers.length - 1].getValue();
        // call again the same downloading method with new URL
        return downloadBitmap(newUrl);
    } else {
        return null;
    }
}
