Requests是一个优雅而简单的Python HTTP库，专为人类而构建。（来自官方的介绍）

requests是一个很实用的Python?HTTP客户端库，编写爬虫和测试服务器响应数据时经常会用到，很适合做接口测试。

requests是第三方的库，需要先安装：pip3 install requests(python3版本)

requests源码

 1 def request(method,url,**kwargs):
 2     """Constructs and sends a :class:`Request <Request>`.
 3 
 4     :param method: method for the new :class:`Request` object.
 5     :param url: URL for the new :class:`Request` object.
 6     :param params: (optional) Dictionary,list of tuples or bytes to send
 7         in the query string for the :class:`Request`.
 8     :param data: (optional) Dictionary,list of tuples,bytes,or file-like
 9         object to send in the body of the :class:`Request`.
10     :param json: (optional) A JSON serializable Python object to send in the body of the :class:`Request`.
11     :param headers: (optional) Dictionary of HTTP Headers to send with the :class:`Request`.
12     :param cookies: (optional) Dict or CookieJar object to send with the :class:`Request`.
13     :param files: (optional) Dictionary of ``‘name‘: file-like-objects`` (or ``{‘name‘: file-tuple}``) for multipart encoding upload.
14         ``file-tuple`` can be a 2-tuple ``(‘filename‘,fileobj)``,3-tuple ``(‘filename‘,fileobj,‘content_type‘)``
15         or a 4-tuple ``(‘filename‘,‘content_type‘,custom_headers)``,where ``‘content-type‘`` is a string
16         defining the content type of the given file and ``custom_headers`` a dict-like object containing additional headers
17         to add for the file.
18     :param auth: (optional) Auth tuple to enable Basic/Digest/Custom HTTP Auth.
19     :param timeout: (optional) How many seconds to wait for the server to send data
20         before giving up,as a float,or a :ref:`(connect timeout,read
21         timeout) <timeouts>` tuple.
22     :type timeout: float or tuple
23     :param allow_redirects: (optional) Boolean. Enable/disable GET/OPTIONS/POST/PUT/PATCH/DELETE/HEAD redirection. Defaults to ``True``.
24     :type allow_redirects: bool
25     :param proxies: (optional) Dictionary mapping protocol to the URL of the proxy.
26     :param verify: (optional) Either a boolean,in which case it controls whether we verify
27             the server‘s TLS certificate,or a string,in which case it must be a path
28             to a CA bundle to use. Defaults to ``True``.
29     :param stream: (optional) if ``False``,the response content will be immediately downloaded.
30     :param cert: (optional) if String,path to ssl client cert file (.pem). If Tuple,(‘cert‘,‘key‘) pair.
31     :return: :class:`Response <Response>` object
32     :rtype: requests.Response

34     Usage::

36       >>> import requests

38       <Response [200]>

?其中，month主要是用get和post

requests模块发送请求有data、json、params三种携带参数的方法。

params在get请求中使用，data、json在post请求中使用。

‘‘‘requests--get方法r=requests.get(‘https://movie.douban.com/‘)print(r.status_code)    #查看状态码print(r.text)   #查看响应内容print(r.content.decode(‘utf-8‘))    #查看字节流(二进制)print(r.url)    #查看请求地址print(r.encoding)   #查看字符编码print(r.cookies)    #查看cookieprint(r.headers)    #查看请求头信息# 当返回的响应格式是json时，可以用r.json())# 这里有两种方式，一种是直接用请求地址，另一种是用参数的方式传递paramesurl=‘https://movie.douban.com/subject_search?search_text=%E5%93%AA%E5%90%92&cat=1002‘url1=‘https://movie.douban.com/subject_search?search_text=哪吒&cat=1002‘payload={‘search_text‘:‘哪吒‘,‘cat‘:1002}r=requests.get(url1,params=payload)‘‘‘
