java.nio.charset.IllegalCharsetNameException：'ISO-8859-1' [英] java.nio.charset.IllegalCharsetNameException: 'ISO-8859-1'

问题描述

Jsoup.connect("http://www.design.cmu.edu/community.php?s=3").get();

有人可以告诉我为什么代码给我错误：

Could someone please show me why the code gave me the error:

java.nio.charset.IllegalCharsetNameException: 'ISO-8859-1'

推荐答案

问题出现在目标页面。

The problem is in the target page. It is not well-formed at all.

当解析页面时，JSoup尝试修复页面，一件事是将内容类型解析为text / html; charset ='iso-8859-1'（带单引号）。

When parsing the page, JSoup tries to fix the page and for one thing, parses the content type to "text/html; charset='iso-8859-1'"(with the single quotes included).

然后传递此字符串（使用单引号），并使用它charset：

It then passes this string(with the single quotes) and uses it to get the charset:

Charset.forName("'ISO-8859-1'");

这会失败。

在目标页面。
也许你可以使用这个替代方法，它不解析页面中的字符集，因为你明确地传递它：

The problem is in the target page. Maybe you can use this alternative instead, which doesn't parse the charset from the page, because you explicitly pass it along:

String url = "http://www.design.cmu.edu/community.php?s=3";
Document document = Jsoup.parse(new URL(url).openStream(), "ISO-8859-1", url);
