|
|
see: http.request To send an HTTP request.
|
|
---
|
|
|
|
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
|
|
1. @{string}: The event name.
|
|
2. @{string}: The URL of the site requested.
|
|
3. @{string}: An error describing the failure.
|
|
4. @{http.Response|nil}: A response handle if the connection succeeded, but the server's response indicated failure.
|
|
|
|
## Example
|
|

|

|
local event, url, err
