1. 新建分支
git checkout -b D-DSG3017-XZZ
2. 删除远程分支
git push origin --delete D-DSG3017-XZZ
3. 删除本地分支<注意：先切换到别的分支上才能删除>
git branch -d D-DSG3017-XZZ
4. 新建分支并切换到该分支：
git checkout -b D-scrollTop-XZZ
5. 提交分支到远程
git push origin D-scrollTop-XZZ:D-scrollTop-XZZ
但是提交不了 报错: RPC failed; HTTP 411 curl 22 The requested URL returned error: 411 Length Required

Everything up-to-date
错误原因：git POST 缓冲区过小.
解决方案：输入以下命令行 再重新提交就OK了
git config http.postBuffer 524288000
6.切换到远程分支
git checkout -b V5.2.6 origin/V5.2.6
作用是checkout远程的V5.2.6分支，在本地起名为V5.2.6分支，并切换到本地的V5.2.6分支
