HTTP 错误代码 505 [英] HTTP error code 505

问题描述

我已经在谷歌上搜索到 505 是不支持 HTTP 版本"，但仍然无法弄清楚我的问题.我有一个带有 Tomcat 的 Web 应用程序，服务器端带有自签名证书以启用 HTTPS，无需对客户端进行身份验证.客户端将验证服务器证书.我已经分析了wireshark数据包，看来SSL handshark是正确的.但是当我检查Tomcat localhost_access_log时，客户端请求会出现505错误，服务器端也没有收到客户端请求.你能帮忙提供一些提示吗?

I have already googled that 505 is "HTTP Version not supported", but still can not figure out my problem. I have a web application with Tomcat,server side with self-signed certificate to enable HTTPS,without authenticating client. The client will authenticate server certificate. I have analyze the wireshark packet, it seems the SSL handshark is correct. But when i check Tomcat localhost_access_log,there will be an 505 error for the client request, also server side does not receive the client request. Could you kindly help to give some hint on this?

推荐答案

如果您在 HTTP 版本之后使用尾随空格向 Tomcat 发出请求(如您的示例中所示)，Tomcat 将响应 505 错误.已在 Tomcat 7.0.27 上确认.

If you make a request to Tomcat with trailing whitespace after the HTTP version (as in your example), Tomcat will respond with 505 error. Confirmed on Tomcat 7.0.27.

RFC 2616 (HTTP 1.1) 规定 HTTP-Version 由 "HTTP/" + digit + "." 组成.+ 数字.请求行以 " " + HTTP-Version + CRLF 结尾，这意味着在最后一位数字之后不允许有空格.

RFC 2616 (HTTP 1.1) says that the HTTP-Version is made up of "HTTP/" + digit + "." + digit. Request-Line ends with " " + HTTP-Version + CRLF which means no whitespace is allowed after that last digit.
