After receiving and interpreting a request message, a server responds with an HTTP response message. The response message has a Status-Code. It is
a 3-digit integer where first digit of the Status-Code defines the class of response and the last two digits do not have any categorization role.
There are 5 values for the first digit:
Status Codes
S.N. | Code and Description |
---|---|
1 | 1xx: Informational
It means the request was received and the process is continuing. |
2 | 2xx: Success
It means the action was successfully received, understood, and accepted. |
3 | 3xx: Redirection
It means further action must be taken in order to complete the request. |
4 | 4xx: Client Error
It means the request contains incorrect syntax or cannot be fulfilled. |
5 | 5xx: Server Error
It means the server failed to fulfill an apparently valid request. |
Successful Response
In the below example we access a file from a url and the response is successful. So the status code returned is 200.
import urllib3 http = urllib3.PoolManager() resp = http.request(''GET'', ''http://tutorialspoint.com/robots.txt'') print resp.data # get the status of the response print resp.status
When we run the above program, we get the following output −
User-agent: * Disallow: /tmp Disallow: /logs Disallow: /rate/* Disallow: /cgi-bin/* Disallow: /videotutorials/video_course_view.php?* Disallow: /videotutorials/course_view.php?* Disallow: /videos/* Disallow: /*/*_question_bank/* Disallow: //*/*/*/*/src/* 200
Unsuccessful Response
In the below example we access a file from a url which does not exist. The response is unsuccessful. So the status code returned is 403.
import urllib3 http = urllib3.PoolManager() resp = http.request(''GET'', ''http://tutorialspoint.com/robot.txt'') print resp.data # get the status of the response print resp.status
When we run the above program, we get the following output −
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>403 Forbidden</title> </head><body> <h1>Forbidden</h1> <p>You don''t have permission to access /robot.txt on this server.</p> </body></html> 403
