解决方案：
使用 jenkins 的 emailext 插件配置邮件正文的模板，emailext 的模板中可以使用 groovy 获取 jenkins api 和 jenkins job 的环境变量，然后获取到关键信息，展示在邮件中。（问题网上的解决方案参考：
Allure Summary Email using Email-ext Jenkins Plugin 5
）。
1、安装Jenkins中安装插件emailext。
2、在%JENKINS_HOME%\email-templates下放入groove脚本(如果没有email-templates，手动新建)：
复制以下代码，且将脚本中的user，password改为可登陆Jenkins的账号。使用txt文件(不要用utf-8格式)，另存为allure-report.groovy文件，将此文件放入%JENKINS_HOME%\email-templates下。

存放位置如下图：
3、修改groovy脚本中的账号密码，让邮件中Allure results trend图片能显示：
4、在Jenkins配置中使用allure-report.groovy
在Jenkins配置的邮件通知中，Default Content：${SCRIPT, template="allure-report.groovy"}，如下图：
5、最终得到一个比较直观带数据的测试结果
此方案还是有些问题，比如如果想查看allure报告，还是需要登录Jenkins，目前也没有好的方案。想到的是可以使用另外起一个服务来打开Jenkins中的allure-report，有实现无需登录Jenkins查看Allure报告的同学欢迎交流：32712784。
