Life is too short, I use python 3

　　HTTP protocol and methods of Requests library

　　The main method of the requests library: requests.request() constructs a request

　　　　　　　　　　　　　requests.get() is the main method for obtaining HTML pages, corresponding to HTTP GET

　　　　　　　　　　　　　The method of requests.head() to get the HTML page header, corresponding to the HTTP HEAD

　　　　　　　　　　　　　requests.post() submits a POST request to a web page, corresponding to HTTP POST

　　　　　　　　　　　　　requests.put() submits a PUT request to an HTML web page, corresponding to HTTP PUT

　　　　　　　　　　　　　requests.patch() submits a partial modification request to an HTML page, corresponding to HTTP PATCH

　　　　　　　　　　　　　requests.delete() deletes requests to HTML pages, corresponding to HTTP DELETE

　　Note: Consistent with HTTP operation

　　The HTTP protocol uses URL as an identifier for locating network resources

　　Format: http://host[:port][path]

　　host: a valid hostname or IP address

　　port: port number, default is 80

　　path: the path of the requested resource

　　Understand the difference between PSTCH and PUT

　　

　　Use headers to get header information, and text is empty
