一般来说软件开发相关企业都会有自己内部的源代码管理工具，比如私有部署的gitlab服务器。特别是企业上规模之后会有多个产品线，各个业务产品线各自的项目解决方案会非常多。

以我们公司为例，就招聘事业部来说，内部的大大小小的中台ESB、MRest、各种Consumer消费端、各种工具等等解决方案现在已经上百个了。这个时候你就会遇到如下一些场景：


(资料图)

1.需要修改某个公共接口的参数或者某个基础库项目包中的公共方法，但是不知道到底哪些项目、哪些地方引用了该接口，不好评估影响点？

2.业务代码中已知道某个Kafka Topic，但是当初写代码兄弟没备注消费端的项目，找了很久就是找不到Consumer项目在哪儿？

3.我想通过某一些特定的关键词搜索某一段代码，记不清到底在哪些项目中使用了？

如果你有上述的困惑，那么下面介绍的这个gitlab 全局 Search代码搜索工具能够帮你解决这些问题。工具的实现采用python + selenium + chromedriver实现自动化登录内部gitlab站点，通过勾选默认配置的产品分组，实现对多个分组内的项目代码特定多个关键词查询搜索。工具的运行流程及界面大概如下面几幅截图所示：

step1.读取配置文件信息自动登录：

{  "username": "yourname",  "password": "yourpassword",  "projectGroups": [    "recrxxx",    "platform-uiframework",    "platform-infrastructure",    "ux-share-platform"  ]}

step2: 登陆成功后主页注入搜索填充信息，可选择的搜索项目分组、关键词录入框等

step3:开始遍历项目分组，获取项目id，并执行关键词搜索

step4：获取命中结果展示，小于等于10个结果的会默认打开浏览器tab页全部展开，大于10个结果的需要手动打开单个或全部

step5:因为使用的chromedriver来驱动实现的，需要注意chrome浏览器版本与chromedriver版本的匹配，如不匹配会记录如下日志；

主要利用python 驱动 selenium 实现自动化控制gitlab项目页面，通过注入特定html标签代码，实现自动化搜索gitlab项目代码。下面是python脚本部分主要实现：
