Web Pipr (piper)

Webpipr allows you to send one request to it and wait for a second request to hit it. It can be used for services like TelAPI, to pass XML to a call request.

http://webpipr.com/new/ will get you a new url to listen on.

Basic Usage

POST and GET params are passed to the waiting request.

• Wait for callback: Send request to http://webpipr.com/wait/somerandomstring
• Send callback: Send request to http://webpipr.com/callback/somerandomstring

Window 1

$ curl webpipr.com/wait/somerandomstring
last=3
first=1

Window 2

$ curl 'webpipr.com/callback/somerandomstring?first=1&last=3'

Timeouts

Use --max-time or -m for curl to timeout if it hasn't received the callback in a set amount of time.

$ curl -m 5 webpipr.com/wait/anotherrandomstring
curl: (28) Operation timed out after 5005 milliseconds with 0 out of -1 bytes received

Parameter formats

You may append a file extension to the url to set the content type. For the waiting request, if .json is appended, the outpu will be encoded as json.

Window 1

$ curl --max-time 30 webpipr.com/wait/parametertest.json
{
    "first": "1",
    "last": "3"
}

Window 2

$ curl 'webpipr.com/callback/parametertest?first=1' -d 'last=3'

Source content

Use --data-binary @- to tell curl to send the piped in stdin to the callback request.

Window 1

$ echo '<Response><Say>Hello worl</Say></Response>' | curl --data-binary @- webpipr.com/wait/customcontent

Window 2

$ curl 'webpipr.com/callback/customcontent.xml'
<Response><Say>Hello worl</Say></Response>
