安全漏洞|pip-audit：功能强大的安全漏洞扫描工具( 三 ) Python|path|网络安全

  --require-hashes      require a hash to check each requirement against for

                        repeatable audits; this option is implied when any

                        package in a requirements file has a `--hash` option.

                        (default: False)

退出代码任务完成后，pip-audit将会退出运行，并返回一个代码以显示其状态，其中：

0：未检测到已知漏洞；
1：检测到了一个或多个已知漏洞；

工具使用样例审计当前Python环境中的依赖：
$ pip-audit

No known vulnerabilities found

审计给定requirements文件的依赖：
$ pip-audit -r ./requirements.txt

No known vulnerabilities found

审计一个requirements文件，并排除系统包：
$ pip-audit -r ./requirements.txt -l

No known vulnerabilities found

审计依赖中发现的安全漏洞：
$ pip-audit
