从HTML Java读取时保留特殊字符? [英] Retaining special character while reading from html java?
问题描述
我正在尝试读取html源文件，其中包含诸如äöü€€的德语字符
i am trying to read html source file which contains German characters like ä ö ü ß €
使用JSOUP进行阅读
Reading using JSOUP
citAttr.nextElementSibling().text()
使用
unicodeEscaper.translate(citAttr.nextElementSibling().text())
org.apache.commons.lang3.text.translate.UnicodeEscaper
问题是在读取字符后变成
Issue is after reading the charecters turns into �
但是在读取Unicode类型为UTF-8的CSV以及上面的unicodeEscaper保存和保存的地方检索字符可以正常工作.
But where as reading CSV with Encoded type UTF-8 with above unicodeEscaper saving & retriving the charecters works fine.
unicodeEscaper.translate(record.get(headerPosition.get(0)))
从html读取有什么问题?尝试使用StringUtilEscaper方法仍然将字符转换为
Whats the issue with reading from html ?? did try with StringUtilEscaper methods still the charecters turns into �
private String getText(Part p) throws MessagingException, IOException {
if (p.isMimeType("text/*")) {
String s = (String) p.getContent();
textIsHtml = p.isMimeType("text/html");
return s;
}
这是我阅读具有html内容的电子邮件的方式！
This is how i am reading email which have html content!
推荐答案
我今天刚刚回答了一个类似的问题...我想我可以输入关于扩展字符集(外语字符)的知识，因为那是一个我编写的软件的主要方面.
I just answered a similar question today... I guess I can just type what I know about extended character sets (foreign-language characters), since that's one of the major facets of the software I write.
- Java内部的
String's均使用16-bit chars(原始类型char是一个16位原始值.名称UTF-8有点误导，因为它用来表示16位的"Unicode空间"(使用两个8位数字).这意味着Java(和JavaString's) 代表整个Unicode外语字母范围没有问题. - JSoup，以及几乎所有用Java编写的HTML工具，当要求下载网站页面时，都将返回16位字符-作为Java
String's-很好，没有任何问题！如果查看这些范围时遇到问题，则可能不是下载过程，也不是JSoup或HttpUrlConnection设置.当您将网页保存到Java中的字符串中时，您并没有丢失那些字符，实际上您会得到UTF-8免费". - 方法:每当程序员尝试将
UTF-8 String保存到'.txt' File或'.html' File，然后继续在网络浏览器中查看该内容(该文件)，您可能会看到的只是那个烦人的问号:.这是因为您需要确保让您的Web浏览器知道使用Java保存的'.html' File-不能用(更旧，更多较短)8-bit ASCII范围.
- Java's internal
String'sall use16-bit chars(The primitive typecharis a 16-bit primitive value. The nameUTF-8is a little misleading since it is used to represent the 16-bit "Unicode Space" (using two 8-bit numbers). This means that Java (and JavaString's) have no problems representing the entire Unicode foreign-language alphabet ranges. - JSoup, and just about any HTML tool written in Java, when asking for website pages to download, will return 16-bit characters - as Java
String's- just fine, without any problems! If there are problems viewing these ranges, it is likely not the download process, nor a JSoup orHttpUrlConnectionsetting. When you save a web-page to a String in Java, you haven't lost those characters, you essentially getUTF-8"for free." - HOWEVER: Whenever a programmer attempts to save a
UTF-8 Stringto a'.txt' Fileor a'.html' File, if you then go on to view that content (that file) in a web-browser, all you might see is that annoying question mark: �. This is because you need to make sure to let your web-browser know that the'.html' Filethat you have saved using Java - is not intended to be interpreted using the (much older, much shorter)8-bit ASCIIRange.
如果您在任何网络浏览器中查看 '.html' File ，或将该文件上传到Google Cloud Platform(或某些托管网站)，则必须执行以下两项操作之一:
If you view an '.html' File in any web-browser, or upload that file to Google Cloud Platform (or some hosting site), you must do one of two things:
- 在注释中包括
<META> Tag:HTML页面的<HEAD> ... </HEAD>部分中的<meta charset="UTF-8">.- 或者在您必须将文件标识为
'text/html, charset=UTF-8'的任何托管平台中提供设置.在Google Cloud Platform存储桶中，有一个弹出菜单，用于将此设置分配给任何文件.
- Include the
<META> Tagmentioned in the comments:<meta charset="UTF-8">in the HTML Page's<HEAD> ... </HEAD>section.- Or provide the setting in whatever hosting platform you have to identify the file as
'text/html, charset=UTF-8'. In Google Cloud Platform Storage Buckets there is a popup menu to assign this setting to any file.
