Want to redirect page to a url after the service completes (passin output from service as parameter to the url)

Appreciate help- from people already familiar with this.
Thanks,

Could your output template just include a <HEAD> and some <META> to redirect?

Something like the following may work:

<HTML>
<HEAD>
<TITLE>Your title</TITLE>
<META HTTP-EQUIV=Refresh CONTENT=“0; URL=URL TO REDIRECT TO”>
</HEAD>
<BODY></BODY>
</HTML>

Good idea , thanks but can I dynamically pass the data from flow as parameter to the URL. Because I guess output templates are prebuilt files… which means the META URL “has” to be prebuilt too…
isn’t it?
Thanks,

You can pass dynamic information to the template. Just use

URL=%value url%

and then the redirect URL to the url pipeline variable in your flow.

Thats nice to know. I didnt know that output templates accept variable substitutions,
Thanks!!!

Tried this, but it would have been very neat if there existed a way to call the URL directly instead of having to redirect to it…the small refresh delay is unavoidable in the case of redirection…

You could do a call to pub.client:http to the URL that you would redirect to and then call pub.flow:setResponse to override the return of the service with the result from the redirect URL.

Following up on this thread…

Can IS 4.6 issue an HTTP redirect?

ie: In the HTTP exchange below, can IS 4.6 set the “Location:…” response header?

POST /invoke/test HTTP/1.0
…
HTTP/1.1 302 Found
Location: [url]http://www/login?ticket=83298589822536[/url]

The pub.flow:setResponse service doesn’t seem useful.
There is a HTTP response header object in the server’s Java API:
com.wm.net.HttpHeader header = Service.getHttpResponseHeader(…)
We can use this method to set the HTTP response status:
header.setResponse(302, “Found”);
However, this only sets the response status line, not the “Location” response header line below it.

We’ve got to use an HTTP redirect since we’re implementing the OCI/Roundtrip standard which requires a redirect – but we can’t be sure user’s browsers will obey HTTP meta-tags (<meta>) or Javascript location directives (doc.location=“…”).

Sonam,

You can use header.setField(fieldName, fieldValue) to set any field on the response header.

Thanks Rupinder. I just got the same answer from WM Support too.

The com.wm.net.HttpHeader class in the IS Server Java API is undocumented. Here’s what I know about three methods in that class:

// Set HTTP response code
setResponseCode(ResponseCode_Integer);
// Set HTTP response code with reason phrase
setResponseCode(ResponseCode_Integer, ResponseReasonPhrase_String);
//Add HTTP response field.
addField(HeaderFieldName_String, HeaderFieldValue_String);

So the following code in a Java service redirects HTTP invokes of that service to yahoo.com:

com.wm.net.HttpHeader h = Service.getHttpResponseHeader(null);
h.setResponse(302, “Found”);
h.addField(“Location”, “http://yahoo.com”);

Sorry, in my post above, the following method:
setResponseCode
(ResponseCode_Integer, ResponseReasonPhrase_String)

…should really have been:
setResponse
(ResponseCode_Integer, ResponseReasonPhrase_String)
