Invalid character found in method name. HTTP method names must be tokens详解编程语言

一月 19, 2019 11:37:32 上午 org.apache.coyote.http11.AbstractHttp11Processor process
信息: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

将SSLEngine=”on”改为off后，重启。

<Listener className=”org.apache.catalina.core.AprLifecycleListener” SSLEngine=”off” />

网上其他参考方案：

1.Tomcat的header缓冲区大小不够,只需要在server.xml中增加maxHttpHeaderSize字段即可:

 <Connector URIEncoding=”UTF-8″ port=”8080″ protocol=”org.apache.coyote.http11.Http11NioProtocol”
useBodyEncodingForURI=”false”
enableLookups=”false”
               connectionTimeout=”20000″

               redirectPort=”8443″ maxHttpHeaderSize=”你想要的大小”/>

2.可能是因为请求协议不对，需要统一成https或http请求。
