How to get parmeters from http request

[Sachin Mehrotra <sm...@tibco.com>]

Hi,

I am not able to figure out how I will get the httprequest parameters on
the Http server side using http-core API. Do I have to retrieve them
from the input stream which I get from the Entity object by writing my
own logic or is there some API there in HTTP-Core?  

 

Thanks,

Sachin

Hi Sachin,

The philosophy of HttpCore is that it provides, well, only core
functionality: a transport to deliver HTTP messages from one endpoint to
another. Everything that has to do with application specific content
should be provided externally.

Yes, you do. HttpClient has an HttpEntity implementation intended to
generate URL encoded form content [1]. What you have to do is to
implement an HttpEntity wrapper that performs the reverse operation:
reads the content from the InputStream, parses it into an array of
name / value pairs, and finally URL decodes the values.

Since requests about HTTP parameter parsing started to come up with a
depressing regularity, I'll try to find time to implement
UrlDecodedFormEntity but cannot commit myself to any time line for that.

Hope this helps in some way.

Cheers

Oleg
