Getting an array of formFields

[Jacobus]

Hi guys,

I receive message content from a monitoring device in a formal like this:

POST /monitor/status HTTP/1.1              
Host: testingtesting.com                                                
Connection: Keep-Alive                                                         
Content-Type: application/x-www-form-urlencoded                                
Authorization: Basic cmVtb3RlX2 cmVtb3RlX2NsaWVudNsaWVud=                      
Content-Length: 78                                                           
                                                                               
&reading[0]=0004A38E5835;                                              
&reading[1]=0004A3D3F18B;                                                          
&reading[2]=0004A3D3F18B;                                                     

Now if there was only one reading, then I could just use:

formFields('reading) { reading =>
  complete {
    logger.debug("Monitoring data received: " + reading)
    ....
   }

But what is the best way to access an array of measurements like the ones above. Is there some sort of directive available for this?

Thanks in advance. I hope there is someone out there who had a little more coffee than me.

Kind regards,
Jacobus

Hi Jacobus,

it's currently not possible to extract a sequence of values with the formFields directive. See this post[1] on how to extract all form fileds.

FYI: akka-http recently added the * receptacle to extract sequences. [2]

Oops, wrong list!

Just use .* (see http://doc.akka.io/docs/akka-stream-and-http-experimental/2.0-M2/scala/http/routing-dsl/directives/form-field-directives/formFields.html)

Thanks so much Andre!

This was exactly what I was looking for.

Kind regards,

Jacobus
