Apache 反向代理将 POST 请求转换为 GET 请求

Question

我正在尝试使用 SonarQube 分析来自 Jenkins 作业的代码，但当请求出现 405 错误时，我的作业失败了。 Apache 基本上是将 POST 请求更改为 GET 请求，从而导致作业失败。

这是我的 apache 虚拟主机配置：

 <VirtualHost *:80>

      ServerName public.dev
   Redirect permanent / https://public.dev/

</VirtualHost>

<VirtualHost *:443>
   SSLEngine on
   SSLCertificateFile /etc/httpd/ssl/wildcard_cnp_dev.pem
   SSLCertificateKeyFile /etc/httpd/ssl/wildcard_cnp_dev.key

      ServerName public.dev

   ProxyPass / http://localhost:9000/
   ProxyPassReverse / http://localhost:9000/
   ProxyRequests Off
   ProxyPreserveHost on

   RequestHeader set X-Forwarded-Proto "https"
   RequestHeader set X-Forwarded-Port "443"

   <Proxy *>
      Order allow,deny
      Allow from all
   </Proxy>

   ErrorLog /var/log/httpd/sonar-https-error.log
   LogLevel warn
   CustomLog /var/log/httpd/sonar-https-access.log combined

</VirtualHost>

当作业失败时，我得到这个控制台输出：

405 错误是因为 SonarQube 正在接收 GET 请求而不是 POST 请求（正常行为）。我可以在 Apache 和 Sonar 访问日志中看到它：

APACHE
192.168.100.7 - - [01/Feb/2016:09:03:06 -0500] "GET /api/ce/submit?projectKey=java-sonar-runner-simple&projectName=Simple%20Java%20project%20analyzed%20with%20the%20SonarQube%20Runner HTTP/1.1" 405 51 "-" "SonarQubeRunner/2.5.1"

SONAR
127.0.0.1 - - [01/Feb/2016:09:14:08 -0500] "GET /api/ce/submit?projectKey=java-sonar-runner-simple&projectName=Simple%20Java%20project%20analyzed%20with%20the%20SonarQube%20Runner HTTP/1.1" 405 51 "-" "SonarQubeRunner/2.5.1"

这在我不使用 Apache 作为反向代理时有效。 Jenkins 在一台机器上，Apache 和 SonarQube 在另一台机器上。

知道为什么会发生这种情况，或者如何解决它？

Answer 1

如果你想在 Sonar 前面放置一个 Apache 反向代理，然后从 Jenkins 访问它，那么你应该在 URL 中添加一个上下文。在声纳服务器上，编辑您的 sonar.properties 文件并编辑以下属性以添加上下文。上下文可以是任何东西...这是我的：

sonar.web.context=/quality

然后在 Apache 中编辑您的代理设置。这是我的：

    ProxyPass /quality http://another-machine:9000/quality keepalive=on
    <Location /quality>
            ProxyPassReverse http://another-machine:9000/quality
    </Location>

希望对您有所帮助。
