TypeError: request() missing 1 required positional argument: 'url' in urllib3

Question

我正在深入研究 Python 并且正在浏览 urllib3 的文档。尝试了运行代码，但似乎没有按预期方式工作。我的密码是

import urllib3

t = urllib3.PoolManager
test = t.request('GET', 'https://shadowhosting.net/')
print(test.data)

我得到的错误是

TypeError: request() missing 1 required positional argument: 'url'

我试过换地方但还是不行。我正在关注文档的开头（用户指南）供参考 - https://urllib3.readthedocs.io/en/latest/user-guide.html

Answer 1

打错了，忘记了创建对象的括号：

t = urllib3.PoolManager()

添加它们，它将像魔术一样工作：

import urllib3

t = urllib3.PoolManager()
test = t.request('GET', 'https://shadowhosting.net/')
print(test.data)

Answer 2

如果您想向 URL 发出 GET 请求，那么您可以使用 requests 模块

import requests

response = requests.get('https://shadowhosting.net/')
print(response.text)

Answer 3

https://urllib3.readthedocs.io/en/latest/user-guide.html 的文档说：

    import urllib3

    http = urllib3.PoolManager()    //You were missing this paranthesis
    r = http.request('GET', 'http://httpbin.org/robots.txt')

或 POST 请求

r = http.request('POST','http://httpbin.org/post', fields={'hello': 'world'})

TypeError: request() missing 1 required positional argument: 'url' in urllib3

TypeError: request() missing 1 required positional argument: 'url' in urllib3
