比如我的账号和密码分别是

• 账号：username
• 密码：123@456

如果按照如下写法就会报错

[remote "origin"]url = "https://username:123@456@demo.github.com/username/project.git"fetch = +refs/heads/*:refs/remotes/origin/*

正确的写法是将特殊字符编码

比如 @ 字符需要编码为%40

正确的写法

[remote "origin"]url = "https://username:123%40456@demo.github.com/username/project.git"fetch = +refs/heads/*:refs/remotes/origin/*

特殊字符对应表

空格  -   %20
"       -   %22
#       -   %23
%       -   %25
&       -   %26
(       -   %28
)       -   %29
+       -   %2B
,       -   %2C
/       -   %2F
:       -   %3A
;       -   %3B
<       -   %3C
=       -   %3D
>       -   %3E
?       -   %3F
@       -   %40
\       -   %5C
|       -   %7C
