The valid characters are defined in RFC 7230 and RFC 3986

问题：

现象：链接显示400

报错：

这是现有的接口，服务器上运行没有问题，但是本地就是报错。

google查询得知是Tomcat版本较高的问题

查询服务器Tomcat版本为 7.0.61 ，本地为 8.5

查询版本变更： changelog

Tomcat 8.5.3:

Ensure that requests with HTTP method names that are not tokens (as required by RFC 7231) are rejected with a 400 response

Tomcat 8.5.7:

Add additional checks for valid characters to the HTTP request line parsing so invalid request lines are rejected sooner.

通常，RFC 3986定义的 URI 可以包含以下任何字符：

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~:/?#[]@!$&'()*+,;=

解决：

我的链接中包含了 “^” ，所以需要把他进行URL编码

“ ^ ” 转成 "%5e"

http://localhost:8080/plancenter/admin/booking?sid=1001%5e000116%5e1231231%5e%E5%85%94%E5%AD%90%5e330682199101231225%5e15067198332%5e123123213&corpNo=3702010326

然后就可以成功获取了

Tomcat 8 is not able to handle get request with '|' in query parameters?
