Git 提交或克隆代码失败（hung up unexpectedly)

如果git提交 (push)或克隆 (clone)代码时，报如下的错误：

可以尝试将http.postBuffer参数调大一点：

git config --global http.postBuffer 10M

通过git config --help可以看到http.postBuffer相关的解释：

http.postBuffer Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

即，http.postBuffer参数是HTTP与远程系统交互的缓冲区大小，默认为1MiB（=1.048576MB）。
