一般來說軟件開發相關企業都會有自己內部的源代碼管理工具，比如私有部署的gitlab服務器。特別是企業上規模之后會有多個產品線，各個業務產品線各自的項目解決方案會非常多。
以我們公司為例，就招聘事業部來說，內部的大大小小的中臺ESB、MRest、各種Consumer消費端、各種工具等等解決方案現在已經上百個了。這個時候你就會遇到如下一些場景：
1.需要修改某個公共接口的參數或者某個基礎庫項目包中的公共方法，但是不知道到底哪些項目、哪些地方引用了該接口，不好評估影響點？
2.業務代碼中已知道某個Kafka Topic，但是當初寫代碼兄弟沒備注消費端的項目，找了很久就是找不到Consumer項目在哪兒？
3.我想通過某一些特定的關鍵詞搜索某一段代碼，記不清到底在哪些項目中使用了？
如果你有上述的困惑，那么下面介紹的這個gitlab 全局 Search代碼搜索工具能夠幫你解決這些問題。工具的實現采用Python/ target=_blank class=infotextkey>Python + selenium + chromedriver實現自動化登錄內部gitlab站點，通過勾選默認配置的產品分組，實現對多個分組內的項目代碼特定多個關鍵詞查詢搜索。工具的運行流程及界面大概如下面幾幅截圖所示：
step1.讀取配置文件信息自動登錄：
{
"username": "yourname",
"password": "yourpassword",
"projectGroups": [
"recrxxx",
"platform-uiframework",
"platform-infrastructure",
"ux-share-platform"
]
}
step2: 登陸成功后主頁注入搜索填充信息，可選擇的搜索項目分組、關鍵詞錄入框等
step3:開始遍歷項目分組，獲取項目id，并執行關鍵詞搜索
step4：獲取命中結果展示，小于等于10個結果的會默認打開瀏覽器tab頁全部展開，大于10個結果的需要手動打開單個或全部
step5:因為使用的chromedriver來驅動實現的，需要注意chrome瀏覽器版本與chromedriver版本的匹配，如不匹配會記錄如下日志；
主要利用python 驅動 selenium 實現自動化控制gitlab項目頁面，通過注入特定html標簽代碼，實現自動化搜索gitlab項目代碼。下面是python腳本部分主要實現：
