git的代码量大多数都是根据命令行统计，或者根据第三方插件统计。但是都不满足我的需求，因为我们代码都由gitlab管理，于是想到了通过gitlab暴露出来的接口获取数据。
第一步，生成私钥
登录你的gitlab申请私钥private_token
第二步，获取当前用户可见的所有项目（即使用户不是成员）
接口地址：gitlab的地址/api/v4/projects/?private_token=xxx
返回参数：
1[{ 2 "id":219, 3 "description":"", 4 "name":"share-5.2.3.8", 5 "name_with_namespace":"develop / share-5.2.3.8", 6 "path":"share-5.2.3.8", 7 "path_with_namespace":"develop/share-5.2.3.8", 8 "created_at":"2019-07-10T19:59:29.855+08:00", 9 "default_branch":"master", 10 "tag_list":[ 11 12 ], 13 "ssh_url_to_repo":"git@127.0.0.1:develop/share-5.2.3.8.git", 14 "http_url_to_repo":"http://127.0.0.1/develop/share-5.2.3.8.git", 15 "web_url":"http://127.0.0.1/develop/share-5.2.3.8", 16 "readme_url":"http://127.0.0.1/develop/share-5.2.3.8/blob/master/README.md", 17 "avatar_url":null, 18 "star_count":0, 19 "forks_count":0, 20 "last_activity_at":"2019-07-11T02:53:44.831+08:00", 21 "_links":{ 22 "self":"http://127.0.0.1/api/v4/projects/219", 23 "issues":"http://127.0.0.1/api/v4/projects/219/issues", 24 "merge_requests":"http://127.0.0.1/api/v4/projects/219/merge_requests", 25 "repo_branches":"http://127.0.0.1/api/v4/projects/219/repository/branches", 26 "labels":"http://127.0.0.1/api/v4/projects/219/labels", 27 "events":"http://127.0.0.1/api/v4/projects/219/events", 28 "members":"http://127.0.0.1/api/v4/projects/219/members" 29 }, 30 "archived":false, 31 "visibility":"private", 32 "resolve_outdated_diff_discussions":false, 33 "container_registry_enabled":true, 34 "issues_enabled":true, 35 "merge_requests_enabled":true, 36 "wiki_enabled":true, 37 "jobs_enabled":true, 38 "snippets_enabled":true, 39 "shared_runners_enabled":true, 40 "lfs_enabled":true, 41 "creator_id":14, 42 "namespace":{ 43 "id":17, 44 "name":"develop", 45 "path":"develop", 46 "kind":"group", 47 "full_path":"develop", 48 "parent_id":null 49 }, 50 "import_status":"none", 51 "open_issues_count":0, 52 "public_jobs":true, 53 "ci_config_path":null, 54 "shared_with_groups":[ 55 56 ], 57 "only_allow_merge_if_pipeline_succeeds":false, 58 "request_access_enabled":false, 59 "only_allow_merge_if_all_discussions_are_resolved":false, 60 "printing_merge_request_link_enabled":true, 61 "merge_method":"merge", 62 "permissions":{ 63 "project_access":null, 64 "group_access":{ 65 "access_level":40, 66 "notification_level":3 67 } 68 } 69 },...]
参数这么多我们从中抽取出需要的部分
1[{ 2 "id":219, 3 "name":"share-5.2.3.8", 4 "name_with_namespace":"develop / share-5.2.3.8", 5 "path_with_namespace":"develop/share-5.2.3.8", 6 "http_url_to_repo":"http://127.0.0.1/develop/share-5.2.3.8.git", 7 "created_at":"2019-07-10T19:59:29.855+08:00", 8 "_links":{ 9 "repo_branches":"http://127.0.0.1/api/v4/projects/219/repository/branches", 10 }, 11 },...]
第三步，遍历项目，根据项目id获取分支列表
接口地址：http://gitlab地址/api/v4/projects/项目id/repository/branches?private_token=xxx
传入参数：无
返回参数：
1[{ 2 "name":"master", 3 "commit":{ 4 "id":"d1b9747ba994f19fb6afb069b3751bd3cf21rrrr", 5 "short_id":"d1b974123", 6 "title":"添加仓库", 7 "created_at":"2019-07-11T02:53:32.000+08:00", 8 "message":"添加仓库", 9 "author_name":"admin", 10 "author_email":"admin@gmail.com", 11 "authored_date":"2019-07-11T02:53:32.000+08:00", 12 "committer_name":"admin", 13 "committer_email":"admin@gmail.com", 14 "committed_date":"2019-07-11T02:53:32.000+08:00", 15 "parent_ids":[ 16 "25cf5c94b9ddc762bd2be73e1e542ebd26adadf" 17 ] 18 }, 19 "merged":false, 20 "protected":true, 21 "developers_can_push":false, 22 "developers_can_merge":false 23 },...]
第四步，遍历分支，根据分支name获取commits
注意，当title和message
接口地址：
http://gitlab地址/api/v4/projects/项目id/repository/commits?ref_name=master&private_token=xxx
1[{ 2"id":"d1b9747ba994f19fb6afb069b3751bd3cf21ag32", 3 "author_name":"admin", 4 "authored_date":"2019-07-11T02:53:32.000+08:00", 5 "committer_email":"admin@gmail.com", 6 "committed_date":"2019-07-11T02:53:32.000+08:00", 7 "created_at":"2019-07-11T02:53:32.000+08:00", 8 "author_email":"admin@gmail.com", 9 "short_id":"d1b9747b", 10 "title":"添加仓库", 11 "parent_ids":[ 12 "25cf5c94b9ddc762bd2be73e1e542ebd26aafd" 13 ], 14 "message":"添加仓库 ", 15 "committer_name":"admin" 16 },...]
第五步，根据commits的id获取代码量
接口地址:
http://gitlab地址/api/v4/projects/项目id/repository/commits/commits的id?private_token=xxx
返回参数：
1[{ 2 "id":"d1b9747ba994f19fb6afb069b3751bd3cf21334d", 3 "short_id":"d1b9747b", 4 "title":"添加仓库", 5 "created_at":"2019-07-11T02:53:32.000+08:00", 6 "parent_ids":[ 7 "25cf5c94b9ddc762bd2be73e1e542ebd26ad7sdf" 8 ], 9 "message":"添加仓库 ", 10 "author_name":"admin", 11 "author_email":"admin@gmail.com", 12 "authored_date":"2019-07-11T02:53:32.000+08:00", 13 "committer_name":"admin", 14 "committer_email":"admin@gmail.com", 15 "committed_date":"2019-07-11T02:53:32.000+08:00", 16 "stats":{ 17 "additions":21, 18 "deletions":8, 19 "total":29 20 }, 21 "status":null, 22 "last_pipeline":null, 23 "project_id":219 24},...]
stats里面就是我们想要的代码量了，additions为新增，deletions为删除，total为总量。修改操作实际上是删除之后再新增。
需要注意的是，这里统计出来的代码量是代码行数。
小结
拿到这些数据之后，不管你是存数据库，还是存excel都很方便，完全可以让系统每天定时去跑，不需要手动执行任何命令。
