Question

每当我尝试在Mozilla Firefox浏览器中将特殊字符放入URL中时，如下所示

https://URL/|

要么

https://URL/]

Tomcat返回HTTP状态400 - 错误请求和异常堆栈跟踪，如下所示。

令人惊讶的是，具有特殊字符的相同网址可在Google Chrome浏览器中正

我有以下问题1）我应该在tomcat配置文件中做些什么更改，以便它不应该返回400状态代码和异常堆栈跟踪？ 2）为什么Mozilla Firefox无法对URL进行编码？

注意：我已经在tomcat 9中部署的应用程序中为4XX类型的状态代码配置了一个公共页面，但问题是tomcat在第一个位置返回400个错误请求http状态代码。

从这里查看relaxedPathChars和relaxedQueryChars https://tomcat.apache.org/tomcat-8.5-doc/config/http.html你需要将它们设置为允许的所有先前字符而不转义
