Nginx SSL+tomcat集群,request.getScheme() 取到https正确的协议详解
公司之前用的是http,但是出于苹果app审核和服务器安全性问题,要改为https,我们公司用的是沃通的ssl,按照沃通的官方文档提供的步骤完成服务器的配置。 架构上使用了 Nginx +tomcat 集群, 且nginx下配置了SSL,tomcat 没有配置SSL,项目使用https协议。
配置成功后明明是https url请求,发现 log里面,tomcat获取scheme的时候,一直是http,而不是想像中的https
0415 16:01:10 INFO (PaymentInterceptor.java:44) preHandle() - requestStringForLog: { "request.getRequestURL():": "http://m.xxx.com/payment/paymentChannel?id=212&s=a84485e0985afe97fffd7fd7741c93851d83a4f6", "request.getMethod:": "GET", "_parameterMap": { "id": ["212"], "s": ["a84485e0985afe97fffd7fd7741c93851d83a4f6"] } }
request.getRequestURL() 输出出来的 一直是
http://m.xxx.com/payment/paymentChannel?id=212&s=a84485e0985afe97fffd7fd7741c93851d83a4f6
但是浏览器中的URL却是
https://m.xxx.com/payment/paymentChannel?id=212&s=a84485e0985afe97fffd7fd7741c93851d83a4f6
下面我们进一步研究发现,java API上写得很清楚:
getRequestURL():
Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.
也就是说, getRequestURL() 输出的是不带query string的路经(含协议,端口,server path等信息).
并且还发现
- request.getScheme() //总是 http,而不是实际的http或https
- request.isSecure() //总是false(因为总是http)
- request.getRemoteAddr() //总是 nginx 请求的 IP,而不是用户的IP
- request.getRequestURL() //总是 nginx 请求的URL 而不是用户实际请求的 URL
- response.sendRedirect( 相对url ) //总是重定向到 http 上 (因为认为当前是 http 请求)
那么解决方案有没有呢,答案是肯定的,其实解决方法非常的简单,只需要分别配置一下 Nginx 和 Tomcat 就好了,而不用从程序代码上修改。
1.配置nginx的转发项,配置文件为proxy.conf,内容如下:
proxy_connect_timeout 300s; proxy_send_timeout 900; proxy_read_timeout 900; proxy_buffer_size 32k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_redirect off; proxy_hide_header Vary; proxy_set_header Accept-Encoding ''; proxy_set_header Referer $http_referer; proxy_set_header Cookie $http_cookie; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme;
其中的proxy_set_header X-Forwarded-Proto $scheme;起到了关键性的作用。
2.配置tomcat,配置文件为server.xml,内容如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE server-xml [ <!ENTITY vhost-localhost SYSTEM "file:///usr/local/tomcat-interface/conf/vhost/localhost.xml"> ]> <Server port="8006" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener"/> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/> <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener"/> <Listener className="org.apache.catalina.core.AprLifecycleListener"/> <GlobalNamingResources> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> </GlobalNamingResources> <Service name="Catalina"> <Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol" connectionTimeout="20000" redirectPort="8443" maxThreads="1000" minSpareThreads="20" acceptCount="1000" debug="0" disableUploadTimeout="true" useBodyEncodingForURI="true" enableLookups="false" URIEncoding="UTF-8" /> <Engine name="Catalina" defaultHost="localhost"> <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https"/> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> &vhost-localhost; </Engine> </Service> </Server>
其中关键的语句为:
<Valve classname="org.apache.catalina.valves.RemoteIpValve"
remoteIpHeader="X-Forwarded-For"
protocolHeader="X-Forwarded-Proto"
protocolHeaderHttpsValue="https"/>
配置双方的 X-Forwarded-Proto 就是为了正确地识别实际用户发出的协议是 http 还是 https。
配置完成之后以下的请求访问
request.getScheme() 、request.isSecure() 、request.getRemoteAddr()、request.getRequestURL() 、response.sendRedirect( 相对url )
就都变为正确的结果了,就像用户在直接访问 Tomcat 一样。
