URL Fetch extension
WEBCALL allows us to send asynchronously a request to a distance web service, but it ignores the answer. URLFETCH is designed to send requests synchronously. It blocks until you get an answer from the server.
You need to be authenticated with a valid token with the function AUTHENTICATE before using URLFETCH.
URLFETCH does a GET request on the URL input.
This extension adds the following functions to WarpScript:
URLFETCH always add the following headers:
User-Agent: Java/1.8.0_171 Host: localhost:9001 Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive
Your custom configurations can be stored in a new
etc/conf.d/99-myWarp10.conf file. Your custom configurations will override all the predefined Warp 10 configurations.
// URLFETCH, MAXURLFETCHCOUNT, MAXURLFETCHSIZE warpscript.extension.urlfetch = io.warp10.script.ext.urlfetch.UrlFetchWarpScriptExtension // Maximum number of URLFETCH calls, 64 by default for soft and hard warpscript.urlfetch.limit = 10 warpscript.urlfetch.limit.hard = 1000 // Maximum downloaded bytes by URLFETCH, 1000000 by default for soft and hard warpscript.urlfetch.maxsize = 1000000 warpscript.urlfetch.maxsize.hard = 1000000000 // List of patterns to include/exclude for hosts, works the same way as webcall.host.patterns. // Defaults to the value of webcall.host.patterns. warpscript.urlfetch.host.patterns = .*
This WarpScript will try to fetch your public IP on different services.
