HttpServletRequest - setCharacterEncoding 似乎什么都不做 [英] HttpServletRequest - setCharacterEncoding seems to do nothing

问题描述

我正在尝试从请求中读取 UTF-8 信息.我使用了request.setCharacterEncoding("UTF-8");"，但它似乎什么也没做——读取的信息不是 UTF-8.

I am trying to read UTF-8 info from the request. I used "request.setCharacterEncoding("UTF-8");", but it seems to do nothing - the info read is non UTF-8.

我做错了什么?

推荐答案

如果您使用的是 tomcat，您还应该在连接器中将 URIEncoding 设置为 UTF-8:

If you are using tomcat, you should also set the URIEncoding to UTF-8 in your connectors:

<Server port="8105" shutdown="SHUTDOWN">
...
    <Service name="Catalina">
        <Connector port="8180" URIEncoding="UTF-8" />
        <Engine name="Catalina" defaultHost="localhost">
            <Host name="localhost" appBase="webapps" />
        </Engine>
    </Service>
</Server>
