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.
