之前，用的还好好的，为什么现在的报告（reporter.html,log.html）打不开了呢？
出现这个问题的原因是：你升级了jenkins造成的。据官方说明：
Jenkins 1.641 / Jenkins 1.625.3 introduce the Content-Security-Policy header to static files served by Jenkins (specifically, DirectoryBrowserSupport). This header is set to a very restrictive default set of permissions to protect Jenkins users from malicious HTML/JS files in workspaces, /userContent, or archived artifacts.
jenkins增加的内容安全策略，默认情况下，是禁止执行javascript,css等资源的。
那么如何解决呢？
找到jenkins的安装目录下的jenkins.xml，修改此文件
修改前
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%jenkins.war" --httpPort=8080</arguments>
修改后
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -Dhudson.model.DirectoryBrowserSupport.CSP="default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; img-src 'self' 'unsafe-inline';" -jar "%BASE%jenkins.war" --httpPort=8080</arguments>
一定要重启jenkins，最好能再执行一下测试脚本，让它生成新的报告文件就行了。
