Jenkins 日志解析器插件 - 已解析的控制台日志页面未显示 X-Frame-Options 拒绝的加载不允许框架 ERR_BLOCKED_BY_RESPONSE
Jenkins Log parser plugin - parsed console log page is not showing Load denied by X-Frame-Options does not permit framing ERR_BLOCKED_BY_RESPONSE
詹金斯版本：1.642.3 或 2.32.3

日志解析器插件：2.0
正在从我的 Mac OS sierra 机器上浏览 Jenkins。
在Jenkins全局配置中，我创建了一个新条目（描述和文件路径（完整），其中文件包含以下内容）。
error /ERROR: Couldn't find any revision to build./

我创建了一个测试作业并捕获所有这些情况（如上所列），在作业的 post-build 部分中，我通过选择相同的日志解析文件条目启用 "Console output (build log) parsing" (列表框选择）。
我 运行 构建并且正如预期的那样失败了。
Build step 'Console output (build log) parsing' changed build result to FAILURE
在作业的仪表板上，我看到了这个。
单击 Parsed Console Output（左侧栏），将我带到一个页面，但没有提供任何有意义的信息。
当我将鼠标悬停在上面的侧边栏 link 上时，它显示 Jenkins 正在寻找 https://.../../parsed_console URL 给定的作业构建号（如上图的地址栏所示).
我在这里缺少什么来获取包含所有错误、警告和信息仪表板的已解析控制台输出页面，就像这个插件声称在此处提供的内容：https://wiki.jenkins.io/download/attachments/43713289/parsed_console_output_3.JPG?version=1&modificationDate=1271216347000&api=v2
PS:
在我的 $JENKINS_HOME（在 master 上）的插件文件夹下，我看到 "log-parser.hpi" 文件（最新文件和 SHA 与我在本地 [=139 下载时看到的匹配） =] 机）。在 Jenkins 重启期间，我没有看到任何与此插件相关的错误日志。
在 Jenkins 作业的 $JENKINS_HOME/jobs//builds/ 文件夹中，我看到有效的 log*.html 有效大小的文件（当您单击 "Parsed Console Output" 侧边栏 link.
时，此插件会读取这些文件以显示信息
浏览 log_ref.html 显示有效 links.

进一步调查此插件的 GitHub source code（LogParserParser.java 文件）以及我在 Jenkins 作业中的 $JENKINS_HOME/jobs //builds// 文件夹，我发现 log.html 可能不正确。不知道为什么它指的是build.log（如href），而没有这样的文件在文件系统上。 PS：<frame src=.... 指的是 log_ref 和 log_content.html 文件，它们都可以正常渲染。

在 Firefox 中：在我的 Mac 机器上的浏览器上 "Parsed Console Output" 边栏 link 执行 检查页面（参考：https://<jenkins_server>/<instance>/job/<job_name>/<someBuildNumber>/parsed_console) 在 Inspect page > Console 部分显示以下行。
Load denied by X-Frame-Options: https://<jenkins_server>/<jenkins_instance>/job/<job_name>/<build_number>/parsed_console/log.html does not permit framing. (unknown)
如果 我浏览 https://<jenkins_server>/<instance>/job/<job_name>/<someBuildNumber>/parsed_console/log.html，那么我会在 Inspect page > Console window 中得到以下几行：

Load denied by X-Frame-Options: https://<jenkins_server>/<jenkins_instance>/job/<job_name>/<build_number>/parsed_console/log_content.html does not permit framing. (unknown)
在Chrome中，在页面上做Inspect，显示如下错误（Refused to display / frame because it set 'X-Frame-Options' to 'deny' / net::ERR_BLOCKED_BY_RESPONSE):
Refused to display 'https://<jenkins_server>/<jenkins_instance>/job/<jobname>/15/parsed_console/job/<jobname>/15/parsed_console/log.html' in a frame because it set 'X-Frame-Options' to 'deny'.

问题不在于插件。
在网页上使用 Inspect，很明显 Apache / Nginx 中的某些内容被设置为 DENY。
我修改了我的 /etc/nginx/sites-enabled/jenkins_https.conf 文件
#add_header X-Frame-Options DENY;
运行
sudo service nginx restart
插件现在按预期呈现输出。
另一个更好的解决方案是：
替换下面一行
#add_header X-Frame-Options DENY;
在您的 nginx 配置文件中添加以下行：
add_header X-Frame-Options SAMEORIGIN;
