python 的requests庫非常的強大,在api自動化框架中,request就是框架核心
request有非常多的功能
除了正常的http請求,還有封裝好能幫你自動保存session庫等
requests.sessions
This module provides a Session object to manage and persist settings acrossrequests (cookies, auth, proxies).
本篇博文就只講常用的兩個http請求方法
requests.sessions
里面的request函數(shù)姐刁,可以持久保留session 使用方法同正常的請求一樣正常的http請求,不會做任何信息的持久保留
import requests
requests.request(method, url, **kwargs)
"""Constructs and sends a :class:`Request <Request>`.
:param method: method for the new :class:`Request` object.
:param url: URL for the new :class:`Request` object.
:param params: (optional) Dictionary, list of tuples or bytes to send
in the query string for the :class:`Request`.
:param data: (optional) Dictionary, list of tuples, bytes, or file-like
object to send in the body of the :class:`Request`.
:param json: (optional) A JSON serializable Python object to send in the body of the :class:`Request`.
:param headers: (optional) Dictionary of HTTP Headers to send with the :class:`Request`.
:param cookies: (optional) Dict or CookieJar object to send with the :class:`Request`.
:param files: (optional) Dictionary of ``'name': file-like-objects`` (or ``{'name': file-tuple}``) for multipart encoding upload.
``file-tuple`` can be a 2-tuple ``('filename', fileobj)``, 3-tuple ``('filename', fileobj, 'content_type')``
or a 4-tuple ``('filename', fileobj, 'content_type', custom_headers)``, where ``'content-type'`` is a string
defining the content type of the given file and ``custom_headers`` a dict-like object containing additional headers
to add for the file.
:param auth: (optional) Auth tuple to enable Basic/Digest/Custom HTTP Auth.
:param timeout: (optional) How many seconds to wait for the server to send data
before giving up, as a float, or a :ref:`(connect timeout, read
timeout) <timeouts>` tuple.
:type timeout: float or tuple
:param allow_redirects: (optional) Boolean. Enable/disable GET/OPTIONS/POST/PUT/PATCH/DELETE/HEAD redirection. Defaults to ``True``.
:type allow_redirects: bool
:param proxies: (optional) Dictionary mapping protocol to the URL of the proxy.
:param verify: (optional) Either a boolean, in which case it controls whether we verify
the server's TLS certificate, or a string, in which case it must be a path
to a CA bundle to use. Defaults to ``True``.
:param stream: (optional) if ``False``, the response content will be immediately downloaded.
:param cert: (optional) if String, path to ssl client cert file (.pem). If Tuple, ('cert', 'key') pair.
:return: :class:`Response <Response>` object
:rtype: requests.Response
"""
文檔說的很詳細具體傳參什么的我就不再對上面的doc做二次翻譯了
下面這個是官方提供的示例,return回的是response對象(object)
Usage::
>>> import requests
>>> req = requests.request('GET', 'https://httpbin.org/get')
<Response [200]>
如果需要從Response對象中得到信息,有以下幾個方法
Response.json(**kwargs)
得到字典格式的response,encoding可選
Response.text
以unicode格式體現(xiàn)的文本
Response.ok
response code < 400 == True 反之 Flase
