前言
使用 pytest 執行 https 請求用例的時候,控制台會出現警告:InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.
當出現這個警告的時候,我們第一反應是加忽略警告:urllib3.disable_warnings(),然而並不管用。
問題描述
使用requests庫發https請求,添加verify=False忽略證書
# test_https.py
import requests
import urllib3
urllib3.disable_warnings()
def test_h():
'''

: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運行用例
D:\demo>pytest test_https.py

這時候會出現 InsecureRequestWarning 警告,去百度搜都是上加上這句
urllib3.disable_warnings()
然而你會發現不管用
問題分析
出現這個問題,並不是因為 'urllib3.disable_warnings()' 不生效,主要是小伙伴門對 pytest 的運行規則不熟悉,pytest 框架運行的時候會查找test_.py文件下的test_()函數或方法的用例
也就是只會執行 test_h()
下面的代碼,所以根本就不會執行它上面的代碼,可以試試換個位置,放到test_h() 以下,就會生效
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() # 換個位置
url = "https://www.cnblogs.com/yoyoketang"
s = requests.session()
s.verify = False
r = s.get(url)
assert "上海-悠悠" in r.text
再次運行 pytest test_https.py
警告就沒有了
warnings 文檔
上面的警告內容有個doc文檔地址Docs: https://docs.pytest.org/en/latest/warnings.html,點開查詢解決方案
文檔上有對於警告出現的詳細描述,在命令行添加--disable-warnings
參數忽略警告
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:\demo
plugins: allure-pytest-2.8.6
collected 1 item
test_https.py . [100%]
==================== 1 passed, 1 warnings in 0.24 seconds =====================
雖然警告內容沒有了,但是警告還是會顯示:1 passed, 1 warnings
也許你想徹底的不想看到warnings,可以不加載 warnings 插件,使用-p參數忽略插件加載
-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`.
帶上 -p 參數運行
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 ===========================
現在可以看到運行結果里面完全沒有 warnings 字樣了
可以在項目根目錄放一個pytest.ini文件,內容如下
[pytest]
addopts = -p no:warnings
這樣使用命令行執行的時候,就可以不用每次都帶-p參數了
