背景：项目中使用gitflow管理分支，jenkins打包时会暂时锁定打包分支避免提交
锁定：
curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/protected_branches?name=feature/chat&push_access_level=30&merge_access_level=30&unprotect_access_level=40"
解锁：
curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/protected_branches/feature/chat"
查看状态：
curl --request GET --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/protected_branches/feature/chat"
锁定和查看都没有问题。当解锁时发现一直返回404 not found
原因：gitlab将/识别为路径分隔符，而不是分支名，使用url编码，查表，用%2F替换/
branchName="feature/chat"
replaceBranchName=$(echo "$branchName" | sed 's/\//%2F/g')
curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/protected_branches/${replaceBranchName}"
