git clone error: RPC failed; result=22, HTTP code = 502

git克隆的工程太大用https的方式会有如下问题

<pre>
hbl:tmp hubert$ git clone https://your-git-project.git
Cloning into 'aios-for-robot'...
error: RPC failed; result=22, HTTP code = 502
fatal: The remote end hung up unexpectedly
</pre>

解决方法如下

1. 通过--depth=1参数解决，拉取的只是master分支的shallow，只是最新的commit
   <pre>
   hbl:tmp hubert$ git clone --depth=1 https://your-git-project.git
   Cloning into 'aios-for-robot'...
   remote: Counting objects: 311, done.
   remote: Compressing objects: 100% (257/257), done.
   remote: Total 311 (delta 49), reused 158 (delta 33)
   Receiving objects: 100% (311/311), 35.17 MiB | 92.00 KiB/s, done.
   Resolving deltas: 100% (49/49), done.
   Checking connectivity... done.
   </pre>

2. 对于在分支开发的开发者来说，不幸的是--depth=1不会把分支拉下来，于是要如下方式，拉取分支到本地
   <pre>
   hbl:aios-for-robot hubert$ git fetch origin lechange:lechange
   remote: Counting objects: 12, done.
   remote: Compressing objects: 100% (11/11), done.
   remote: Total 12 (delta 3), reused 0 (delta 0)
   Unpacking objects: 100% (12/12), done.
   From https://your-git-project/aios/aios-for-robot

• [new branch] lechange -> lechange
  </pre>

3. 拉到本地的分支，并不是远程分支，需要设置upstream提交修改
   <pre>
   hbl:aios-for-robot hubert$ git push
   fatal: The current branch lechange has no upstream branch.
   To push the current branch and set the remote as upstream, use

   git push --set-upstream origin lechange
   </pre>
   <pre>
   hbl:aios-for-robot hubert$ git push --set-upstream origin lechange
   Counting objects: 2, done.
   Delta compression using up to 4 threads.
   Compressing objects: 100% (2/2), done.
   Writing objects: 100% (2/2), 315 bytes | 0 bytes/s, done.
   Total 2 (delta 0), reused 0 (delta 0)
   To https://your-git-project.git
   02a4c0c..f4f5357 lechange -> lechange
   Branch lechange set up to track remote branch lechange from origin.
   </pre>
