认证¶
基本 HTTP 认证¶
pip 支持基于 HTTP 的基本认证凭证。这是通过在 URL 中提供用户名(和可选的密码)来实现的:
https://username:password@pypi.company.com/simple
对于只需要单部分认证令牌的索引,提供令牌作为 “username”,不要提供密码:
https://0123456789abcdef@pypi.company.com/simple
百分号编码的特殊字符¶
10.0 新版功能.
Certain special characters are not valid in the credential part of a URL.
If the user or password part of your login credentials contain any of these
special characters, then they must be percent-encoded. As an
example, for a user with username user
and password he//o
accessing a
repository at pypi.company.com/simple
, the URL with credentials would look
like:
https://user:he%2F%2Fo@pypi.company.com/simple
netrc 支持¶
pip supports loading credentials from a user’s .netrc
file. If no credentials
are part of the URL, pip will attempt to get authentication credentials for the
URL’s hostname from the user’s .netrc
file. This behaviour comes from the
underlying use of requests, which in turn delegates it to the
Python standard library’s netrc
module.
注解
As mentioned in the standard library documentation for netrc,
only ASCII characters are allowed in .netrc
files. Whitespace and
non-printable characters are not allowed in passwords.
Below is an example .netrc
, for the host example.com
, with a user named
daniel
, using the password qwerty
:
machine example.com
login daniel
password qwerty
More information about the .netrc
file format can be found in the GNU ftp
man pages.
Keyring Support¶
pip supports loading credentials stored in your keyring using the keyring library.
$ pip install keyring # install keyring from PyPI
$ echo "your-password" | keyring set pypi.company.com your-username
$ pip install your-package --index-url https://pypi.company.com/
Note that keyring
(the Python package) needs to be installed separately from
pip. This can create a bootstrapping issue if you need the credentials stored in
the keyring to download and install keyring.
It is, thus, expected that users that wish to use pip’s keyring support have some mechanism for downloading and installing keyring in their Python environment.
