tRESTRequest Header and building jobs

Anonymous — Sat, 16 Nov 2024 10:45:05 GMT

Hi,
I currently have a job which look like this :
https://www.talendforge.org/forum/img/members/361125/capture_job.png
And i have some questions :
- How can i get informations from the client (header of the Resquest, client IP, etc …) with tRESTRequest component ?
- Is it possible to make several jobs (with tRESTRequest on the same host) and still get only one war or jar ? Or i need to place all of the tRESTRequest on the same job ?
For examples :
in the first job named SO i have : tRESTRequest_1->Endpoint REST = /SO
in the second job named IS i have : tRESTRequest_1->Endpoint REST = /IS

- As i see, Talend Studio use jetty server :

https://www.talendforge.org/forum/img/members/361125/capture_log4j.png
And i have seen that i can deploy the job on Talend Runtime (with the jar builded) but how can i deploy this job on tomcat ? (When i build my job he forced me to get a jar with OSGI Bundle, cause of tRESTRequest)

I definitely posted a reply this morning but it has not been persisted, may be I got it lost,
but what I typed was that all HTTP headers are available as a map on the request context, the property name is something like "ALL.HTTP.HEADERS" or similar. Another option is to add schema parameters and map them to individual HTTP headers (with a Comment field set to 'header', no quotes).

Thanks for the reply,

I tried to add one parameter (Host) with ‘header’ in comment column and “empty header” in default, and i tried to return the value with tJavaFlex : (tRESTRequest ? tJavaFlex)
main code :
        // try to get all headers
        System.out.println((context.getProperty("ALL_HEADER_PARAMS")));
        // try to get the host
        System.out.println((String)myRowName.Host);
the first row return null, the second return the host !

But i only have the host, what i want is to get all of the headers (Http-Method, Adress, …) like:
mars 15, 2016 4:47:14 PM org.apache.cxf.interceptor.LoggingInInterceptor
INFOS: Inbound Message
----------------------------
ID: 1
Address: http://<host>:<port>/<Uri>?<queryParameter1>=<value1>&<queryParameter2>=<value2>
Http-Method: GET
Content-Type:
Headers: {Accept=, accept-encoding=, Accept-Language=, Cache-Control=, connection=, Content-Type=, Host=, Upgrade-Insecure-Requests=, User-Agent=}
--------------------------------------

(i can’t add schema parameters named like ‘User-Agent’ cause of ‘-’)
I also want to get the client IP.

And i tried to get the response time from tRESTRequest to tRESTResponse (with tStatCatcher, tChronometerStart/Stop) but i can only returned the job execution time when i shutdown my job.
I always try to deploy my jobs on tomcat, but i will probably use Talend Runtime.
Thank you in advance,
Csen.

Hi,
As i said before : context.getProperty("ALL_HEADER_PARAMS") is null.
But i found how to get request parameters (all headers params, URI, query params, ...),
I put this code in my tJavaFlex main code :

// return all request params
java.util.Map<String, java.util.Map<String, List<String>>> restReq = 
(java.util.Map<String, java.util.Map<String, List<String>>>)globalMap.get("restRequest");
System.out.println(restReq);
// return all headers params
//java.util.Map<String, List<String>> headers = restReq.get("ALL_HEADER_PARAMS");
//System.out.println(headers);

and this give me something like :

{URI_ABSOLUTE=, PATTERN=/, 
OPERATION=getInfo, 
ALL_HEADER_PARAMS={Accept=,
 accept-encoding=, Accept-Language=, 
Cache-Control=, connection=, 
Content-Type=, 
CorrelationID=, 
Host=, User-Agent=, Via=, X-Forwarded-For=}, 
VERB=GET, 
MESSAGE_CONTEXT=org.apache.cxf.jaxrs.impl.tl.ThreadLocalMessageContext@6060d0,
 URI_BASE=, 
CorrelationID=urn:uuid:d7285947-8bff-46e1-bd48-cf11504ebe56, PARAMS={}, 
URI=/, ALL_QUERY_PARAMS={id=, q=}, 
URI_REQUEST=}

I still need to deploy this job on tomcat,
Thanks again for your help,
Csen
