Facing issue in HTTP::collect, HTTP::payload

Hi Guys,

 

I have a nice working IRULEs code, but for my additional operations, I'm trying to fetch the complete body from post method using the below code.. but it hangs when I add the code.

 

I'm not finding the proper literature which gives clear idea to use HTTP::collect and HTTP::payload

 

in HTTP_REQUEST

 

if {[HTTP::method] equals "POST"} {

 

if {[HTTP::header Content-Length] > 1 && [HTTP::header Content-Length] < 7000} {

 

set content_length [HTTP::header Content-Length]

 

Use default collect length

 

[HTTP::collect [HTTP::header Content-Length]]

 

log local0.info "10.0023- Printing the SAML response: $SAMLResponse IP: [IP::client_addr]"

 

}

 

}

 

 

when HTTP_REQUEST_DATA {

 

do stuff with the payload

 

set SAMLResponse [HTTP::payload]

 

log local0.info "60.0000- Printing the SAML response: $SAMLResponse IP: [IP::client_addr]"

 

HTTP::release

 

}

 

 

Thanks a lot in advance,

 

Pradeep

    [HTTP::collect [HTTP::header Content-Length]]i do not think you need outer bracket.

     

     

    these are more examples. the latter one is to collect response, so you have to modify it for request.

    That was not the issue, its not working if length is above 200, the data ai send is more than 5500. not able to get the resolution
