前言

使用 pytest 执行 https 请求用例的时候，控制台会出现警告：InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.
当出现这个警告的时候，我们第一反应是加忽略警告：urllib3.disable_warnings()，然而并不管用。

问题描述

使用requests库发https请求，添加verify=False忽略证书

# test_https.py
import requests
import urllib3
urllib3.disable_warnings()


def test_h():
    '''
    author: 上海-悠悠 QQ交流群：779429633
    blog: https://www.cnblogs.com/yoyoketang
    :return: 
    '''
    url = "https://www.cnblogs.com/yoyoketang"
    s = requests.session()
    s.verify = False
    r = s.get(url)
    assert "上海-悠悠" in r.text

命令行使用pytest运行用例

D:\demo>pytest test_https.py
============================= test session starts =============================
platform win32 -- Python 3.6.0, pytest-4.5.0, py-1.5.4, pluggy-0.13.1

这时候会出现 InsecureRequestWarning 警告，去百度搜都是上加上这句

urllib3.disable_warnings()

然而你会发现不管用

问题分析

出现这个问题，并不是因为 'urllib3.disable_warnings()' 不生效，主要是小伙伴门对 pytest 的运行规则不熟悉，pytest 框架运行的时候会查找test_.py文件下的test_()函数或方法的用例
也就是只会执行 test_h() 下面的代码，所以根本就不会执行它上面的代码，可以试试换个位置，放到test_h() 以下，就会生效

import requests
import urllib3
# urllib3.disable_warnings()

def test_h():
    '''
    author: 上海-悠悠 QQ交流群：779429633
    blog: https://www.cnblogs.com/yoyoketang
    :return:
    '''
    urllib3.disable_warnings()  # 换个位置
    url = "https://www.cnblogs.com/yoyoketang"
    s = requests.session()
    s.verify = False
    r = s.get(url)
    assert "上海-悠悠" in r.text

再次运行 pytest test_https.py 警告就没有了

warnings 文档

上面的警告内容有个doc文档地址Docs: https://docs.pytest.org/en/latest/warnings.html，点开查询解决方案

文档上有对于警告出现的详细描述，在命令行添加--disable-warnings 参数忽略警告

pytest test_https.py --disable-warnings

D:\demo>pytest test_https.py --disable-warnings
============================= test session starts =============================
platform win32 -- Python 3.6.0, pytest-4.5.0, py-1.5.4, pluggy-0.13.1
rootdir: D:\soft\kecheng202004\demo
plugins: allure-pytest-2.8.6
collected 1 item

test_https.py .                                                          [100%]

==================== 1 passed, 1 warnings in 0.24 seconds =====================

虽然警告内容没有了，但是警告还是会显示：1 passed, 1 warnings

也许你想彻底的不想看到warnings，可以不加载 warnings 插件，使用-p参数忽略插件加载

 -p name               early-load given plugin module name or entry point
                        (multi-allowed). To avoid loading of plugins, use the
                        `no:` prefix, e.g. `no:doctest`.

带上 -p 参数运行

pytest test_https.py -p no:warnings

D:\demo>pytest test_https.py -p no:warnings
============================= test session starts =============================
platform win32 -- Python 3.6.0, pytest-4.5.0, py-1.5.4, pluggy-0.13.1
rootdir: D:\demo
plugins: allure-pytest-2.8.6
collected 1 item

test_https.py .                                                          [100%]

========================== 1 passed in 0.29 seconds ===========================

现在可以看到运行结果里面完全没有 warnings 字样了

可以在项目根目录放一个pytest.ini文件，内容如下

[pytest]
addopts = -p no:warnings

这样使用命令行执行的时候，就可以不用每次都带-p参数了
