PROC HTTP - get an response HTTP/1.1 411 Length Required

lillejordh · Posted 06-24-2020 11:44 AM

I am using SAS EG ( SAS 9.4.5.0 ) to connect to an REST API using PROC HTTP:

It is token based.

I get an "< HTTP/1.1 411 Length Required" error.

Question: Is there something else I have to specify to avoid this error?

First step: to get a token works fine.

Step two is a POST where I send a JSON GRAPGQL request together with the token and some extra parameters

( I do the same query in POSTMAN and it works fine)

I feed the Token from a file due to the size(>1000 char)

I feed the GraphQL from a file as well

SAS CODE :

PROC HTTP 
   url="https://apis.collabor8.no/stable/graph" 
   method="POST"
   ct="application/json"
   OAUTH_BEARER=token
   out=proddata
   in=query;
   headers 
	 "Ocp-Apim-Subscription-Key" = "&opcSubscriptionKey"
 ; 
    DEBUG LEVEL=3 ;
run;

The HTTP input looks like this:

> POST /stable/graph HTTP/1.1
> User-Agent: SAS/9
> Host: apis.collabor8.no
> Accept: */*
> Authorization: Bearer

The HTTP respons is:

I Googled "HTTP Error 411. The request must be chunked or have a content length", and the results suggests

adding "Content-Length" = "0" to your headers statement

Hope this helps,

Ahmed

Thanks for your repsonse.

I updated my code to include "Content-Length=0" in the headers - but still I get the same error.

Error:

Required</TITLE><META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD><BODY><h2>Length
Required</h2><hr><p>HTTP Error 411. The request must be chunked or have a content length.</p></BODY></HTML>

When I do not include the : "Content-Length=0" SAS sends the length ( e,g. Content-Length: 618 )

SAS code with added Conent-Length

PROC HTTP 
   url="https://apis.collabor8.no/stable/graph" 
   method="POST"
   ct="application/json"
   OAUTH_BEARER=token
   out=proddata
   in=query;
     *VERBOSE ;  
   headers 
   	 "Content-Length" = "0"
	 "Ocp-Apim-Subscription-Key" = "&opcSubscriptionKey"
	 ; 
    DEBUG LEVEL=3 ;
run;
