http_failure
The http_failure event is fired when an HTTP request fails.
This event is normally handled inside http.get and http.post, but it can still be seen when using http.request.
Return Values
- string: The event name.
- string: The URL of the site requested.
- string: An error describing the failure.
- http.Response|nil: A response handle if the connection succeeded, but the server's response indicated failure.
Example
Prints an error why the website cannot be contacted:
local myURL = "https://does.not.exist.tweaked.cc" http.request(myURL) local event, url, err repeat event, url, err = os.pullEvent("http_failure") until url == myURL print("The URL " .. url .. " could not be reached: " .. err)
Prints the contents of a webpage that does not exist:
local myURL = "https://tweaked.cc/this/does/not/exist" http.request(myURL) local event, url, err, handle repeat event, url, err, handle = os.pullEvent("http_failure") until url == myURL print("The URL " .. url .. " could not be reached: " .. err) print(handle.getResponseCode()) handle.close()
