Tomcat 7 cookie包含变音符元时异常

Question

我是一名开发人员，当Cookie包含变音符字符(ä，ö，ü)时，我面临下面的例外，我尝试了许多解决方案和配置，但没有任何结果。

我使用Tomcat7

请给出任何解决方案

Answer 1

根据对另一个问题的评论，您需要升级到tomcat 8.0.15(或更高)并启用RFC 6455 cookie处理器。文档在这里:http://tomcat.apache.org/tomcat-8.0-doc/config/cookie-processor.html

在conf/context.xml中通过:

<Context>
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor" />
</Context>

Answer 2

使用UTF-8编码

可以全局设置:

java -Dfile.encoding=UTF-8

或本地:

System.setProperty("file.encoding", "UTF-8");
byte inbytes[] = new byte[1024];
FileInputStream fis = new FileInputStream("the.location.of.your.cookie");
fis.read(inbytes);

同样，如果您手动编辑cookie，不要保存Ä。而是使用UTF-8等效的

System.out.println("u00c4");

Chars   Unicode
------------------------------
Ä, ä    u00c4, u00e4
Ö, ö    u00d6, u00f6
Ü, ü    u00dc, u00fc
ß       u00df

Answer 3

现在我遇到了同样的问题，首先我尝试将tomcat 7升级到tomcat 8.5.51，它工作，但它提出了新的问题

java.lang.IllegalArgumentException: An invalid domain [.foo.bar.com] was specified for this cookie

因为我不需要cookie在我的情况下，所以我只是排除cookie在Nginx级别，它也可以解决这个问题

    proxy_set_header Cookie "";
