Heroku Permission Denied Solution

在试图push我的app到heroku时git push stage master 总是弹错,信息如下

Warning: Permanently added the RSA host key for IP address '50.19.85.154' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

在Stackflow上找到了解答link

Kris Hollenbeck回答来自Heroku自己的文档 如果需要在heroku商用SSH Git的话，需要创建一对public/private key pair来不输代码。这对秘钥用来进行加密，辨识你为唯一的developer当你改动代码时。

SSH原理我没弄明白，操作如下:

1. 生成一个public key

   (venv) Zephyr (master) project $ ssh-keygen -t rsa
   Generating public/private rsa key pair.
   Enter file in which to save the key (/Users/mac/.ssh/id_rsa):
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in /Users/mac/.ssh/id_rsa.
   Your public key has been saved in /Users/mac/.ssh/id_rsa.pub.
   The key fingerprint is:
   SHA256:/04ujrGjMmvmNXflaxcM9S9HSk6VGC66qLKmeGrWbX8 Zephyr@Zephyr
   The key's randomart image is:
   +---[RSA 2048]----+
   |             .o .|
   |            .....|
   |           . o o |
   |          . o o o|
   |        S.  .* o.|
   |        ...o  * o|
   |  . . o.o.o o  + |
   |.o.+=+.o.E.+...  |
   |=+o=*=oo+o.+=.   |
   +----[SHA256]-----+
   

   点击enter当提示输入时，采用默认位置

2. adding keys to heroku

   Permission denied (publickey).是非常常见的错误，需要通知heroku新的key

   (venv) Zephyr (master) project $ heroku keys:add
   Found an SSH public key at /Users/mac/.ssh/id_rsa.pub
   ? Would you like to upload it to Heroku? Yes
   Uploading /Users/mac/.ssh/id_rsa.pub SSH key... done
   

   再运行git push stage master成功；结果略过
