Git如何通过SSH连接github和如何添加协作开发者

</pre><pre name="code" class="java">**********1.在执行git push origin master指令时报如下错误:

问题:eWfrror: RPC failed; result=56, HTTP code = 200 KiB/s
经上网查询,原因是http.postbuffer值较小,对postBuffer进行修改.

配置完后,继续执行git push origin master指令,依然有问题,再次上网进行查询,经网上建议可以将https方式改为ssh方式.
登录Github发现reomte的url有三种连接方式:https,ssh和svn,git连接github默认使用https.
[email protected] /d/ilucky/message/code (master)
$ git remote set-url origin [email protected]:IluckySi/message.git
[email protected] /d/ilucky/message/code (master)
$ git push origin master
Received disconnect from 192.30.252.129: 11: Bye Bye
fatal: Could not read from remote repository.

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

修改完后,继续执行git push origin master指令,还是有问题,再次上网进行查询,
原来通过ssh连接github需要通过key.
[email protected] /d/ilucky/message/code (master)
$ ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/zhangmengjiao/.ssh/id_rsa):
/c/Users/zhangmengjiao/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 输入github密码
Enter same passphrase again:                输入github密码
Your identification has been saved in /c/Users/zhangmengjiao/.ssh/id_rsa.
Your public key has been saved in /c/Users/zhangmengjiao/.ssh/id_rsa.pub.
The key fingerprint is:
ce:eb:cd:8e:5e:80:e9:3b:d6:f8:c2:75:63:d2:28:0d [email protected]
The key's randomart image is:

生成key后,在/c/Users/用户/目录下会生成一个.ssh目录,将.ssh目录下id_rsa.pub文件中的内容
按照git整理2-1图片添加到github中,添加完成后,再次执行指令,ok,成功了!

$ git push origin master

??????????问题:https,ssh和svn的区别?官方建议使用https.
参考http://stackoverflow.com/questions/11041729/why-does-github-recommend-https-vs-ssh

**********2.添加协作开发者.
按照git整理2-2图片添加协作开发者.
注意:协作开发者也要有自己的GitHub账户,本地的GitHub工作空间.
协作协作开发者通过指令将管理员的项目clone一份,clone的url是管理员的项目url.
这样协作开发者就可以在自己的工作空间对项目进行各种操作了.

除了上面的合作方式,还有一种合作方式:通过fork和pull request.
按照git整理2-3图片将管理员的项目fork一下,即将管理员的项目打一个分支到自己的GitHub上,
然后将自己GitHub上的项目clone一份到本地的工作空间,这样就可以对项目进行各种操作了,这里的操作不会影响到
管理员GitHub上的项目.如果有一天自己的任务完成了,可以通过发一个pull request与管理员分享,
如果管理员认为没有问题,可以进行merge,如果觉得有问题,可以进行讨论.
