In this issue, the editor will bring you about how python sends http requests and receives http responses through get and post. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.
1.GET method
The get method is to put the requested data directly into the url, and then use httplib and urllib2 to simulate the user login.
1)
# URL address
Url_Addr = "https://apac-axlprod01-api.com:8081/userLogin?"
# parameters to be passed when the user logs in
Params = urllib.urlencode ({'name': user_name,' password': user_pwd, 'appId': app_Id})
# there seems to be something wrong with the python certificate I installed, failure check
Ssl._create_default_https_context = ssl._create_unverified_context
# combine parameters and URL into a URL
Req = urllib2.Request (url_Addr+params)
Res = urllib2.urlopen (req)
Data = res.read ()
Res.close ()
2)
# URL address
Url_Addr = "apac-axlprod01-api.com:8081"
# parameters to be passed when the user logs in
Params = urllib.urlencode ({'name': user_name,' password': user_pwd, 'appId': app_Id})
Ssl._create_default_https_context = ssl._create_unverified_context
Conn = httplib.HTTPSConnection (url_Addr)
# combine parameters and URL into a URL
Conn.request ("GET", "/ userLogin?" + params)
Response = conn.getresponse ()
Data = response.read ()
Response.close ()
2.POST method
The POST method is to put the requested data directly in data or body, but not in url. Here, use httplib and urllib2 to simulate user login.
1)
# URL address
Url_Addr = "https://apac-axlprod01-api.com:8081/userLogin"
# parameters to be passed when the user logs in
Params = urllib.urlencode ({'name': user_name,' password': user_pwd, 'appId': app_Id})
Ssl._create_default_https_context = ssl._create_unverified_context
# input URL and Data
Req = urllib2.Request (url = url_Addr,data = params)
Res = urllib2.urlopen (req)
Data = res.read ()
Res.close ()
2)
# URL address
Url_Addr = "apac-axlprod01-api.com"
# headers
Headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
# parameters to be passed when the user logs in
Params = urllib.urlencode ({'name': user_name,' password': user_pwd, 'appId': app_Id})
Ssl._create_default_https_context = ssl._create_unverified_context
Conn = httplib.HTTPSConnection (url_Addr,8081)
# input URL, body and headers
Conn.request ("POST", "/ userLogin", params,headers)
Response = conn.getresponse ()
Data = response.read ()
Response.close ()
Httplib implements the client protocols of http and https, but in python, the modules urllib and urllib2 encapsulate httplib at a higher level
The common types and methods provided by httplib are described in detail below.
Httplib.HTTPConnection (host [, port [, strict [, timeout]])
The constructor of the HTTPConnection class that represents an interaction with the server, that is, the request / response. The parameter host indicates the server host, for example: www.csdn.net;port is the port number, and the default value is 80; the default value of the parameter strict is false, indicating whether to throw a BadStatusLine exception when the status line returned by the server cannot be parsed (status line) (typical status lines such as HTTP/1.0 200 OK); optional parameter timeout indicates the timeout.
The methods provided by HTTPConnection are:
HTTPConnection.request (method, url [, body [, headers]])
Calling the request method sends a request to the server, and method represents the requested method. Commonly used methods are get and post and head; url represents the url of the requested resource; body represents the data submitted to the server and must be a string (if method is "post", body can be understood as the data in the html form); headers represents the http header of the request.
HTTPConnection.getresponse ()
Get the Http response. The returned object is an instance of HTTPResponse, which is explained below about HTTPResponse.
HTTPConnection.connect ()
Connect to the Http server.
HTTPConnection.close ()
Close the connection to the server.
HTTPConnection.set_debuglevel (level)
Sets the level of the height. The default value of the parameter level is 0, which means that no debugging information is output.
Httplib.HTTPResponse
HTTPResponse represents the server's response to client requests. It is often created by calling HTTPConnection.getresponse (), which has the following methods and properties:
HTTPResponse.read ([amt])
Gets the message body of the response. If you are requesting a normal web page, the method returns the html of the page. The optional parameter amt indicates that the specified byte of data is read from the response stream.
HTTPResponse.getheader (name [, default])
Get the response header. Name represents the name of the header domain (header field). The optional parameter default is returned as the default if the header domain does not exist.
HTTPResponse.getheaders ()
Returns all header information as a list.
HTTPResponse.msg
Get all the response header information.
HTTPResponse.version
Gets the http protocol version used by the server. 11 means http/1.1;10 means http/1.0.
HTTPResponse.status
Gets the status code of the response. For example, 200 indicates that the request is successful.
HTTPResponse.reason
Returns a description of the result that the server processed the request. It's usually "OK".
