给一个重定向的URL是一个带空格的URL，Jsoup会导致错误。怎么解决这个？ [英] Giving an url, that redirected is a url with spaces, to Jsoup leads to an error. How resolve this?

问题描述

您好我必须解析URI由服务器重定向解析的页面。

Hello I have to parse pages wich URI is resolved by server redirect.

示例：

I有 http：//www.juventus。重定向的com / wps / poc？uri = wcm：oid：91da6dbb-4089-49c0-a1df-3a56671b7020 http://www.juventus.com/wps/wcm/connect/JUVECOM-IT/news/primavera ％20convocati％20villar％20news％2010agosto2013？pragma = no-cache

这是我必须解析的页面的URI。问题是重定向URI包含空格，这是代码。

This is URI of the page that I have to parse. The problem is that redirect URI contains spaces, here's the code.

    String url = "http://www.juventus.com/wps/poc?uri=wcm:oid:91da6dbb-4089-49c0-a1df-3a56671b7020";
    Document doc = Jsoup.connect(url).get();

    Element img = doc.select(".juveShareImage").first();
    String imgurl = img.absUrl("src");
    System.out.println(imgurl);

我在第二行收到此错误：

I get this error at the second line:

    Exception in thread "main" org.jsoup.HttpStatusException: HTTP error fetching URL. Status=404, URL=http://www.juventus.com/wps/wcm/connect/JUVECOM-IT/news/primavera convocati villar news 10agosto2013?pragma=no-cache

包含重定向的url，因此这意味着JSoup获取了正确的重定向URI。有没有办法用％20替换''所以我可以解析没问题？

that contains the redirected url, so this means that JSoup gets the correct redirected URI. Is there a way to replace the ' ' with %20 so I can parse with no problem?

谢谢！

推荐答案

你是对的。这就是问题。我看到的唯一解决方案是执行重定向手册。我写了这个小的递归方法为你做这个。请参阅：

You are right. This is the problem. The only solution I see is to do the redirects manual. I wrote this small recursive method doing this for you. See:

public static void main(String[] args) throws IOException
{
    String url = "http://www.juventus.com/wps/poc?uri=wcm:oid:91da6dbb-4089-49c0-a1df-3a56671b7020";

    Document document = manualRedirectHandler(url);

    Elements elements = document.getElementsByClass("juveShareImage");

    for (Element element : elements)
    {
        System.out.println(element.attr("src"));
    }

}

private static Document manualRedirectHandler(String url) throws IOException
{
    Response response = Jsoup.connect(url.replaceAll(" ", "%20")).followRedirects(false).execute();
    int status = response.statusCode();

    if (status == HttpURLConnection.HTTP_MOVED_TEMP || status == HttpURLConnection.HTTP_MOVED_PERM || status == HttpURLConnection.HTTP_SEE_OTHER)
    {
        String redirectUrl = response.header("location");
        System.out.println("Redirect to: " + redirectUrl);
        return manuelRedirectHandler(redirectUrl);
    }

    return Jsoup.parse(response.body());
}

这将打印出来

Redirect to: http://www.juventus.com:80/wps/portal/!ut/p/b0/DcdJDoAgEATAF00GXFC8-QqVWwMuJLLEGP2-1q3Y8Mwm4Qk77pATzv_L6-KQgx-09FDeWmpEr6nRThCk36hGq1QnbScqwRMbNuXCHsFLyuTgjpVLjOMHyfCBUg!!/
Redirect to: http://www.juventus.com/wps/wcm/connect/JUVECOM-IT/news/primavera convocati villar news 10agosto2013?pragma=no-cache
/resources/images/news/inlined/42d386ef-1443-488d-8f3e-583b1e5eef61.jpg

我还为Jsoup添加了一个补丁为此：

I also added a patch for Jsoup for that:
