Newman: postman.getResponseHeader cant's get full content of Header value

[snk20501]

1. Newman Version (can be found via newman -v): 3.8.3
2. OS details (type, version, and architecture): Ubuntu 16.04.02 64bit LTS server
3. Are you using Newman as a library, or via the CLI? CLI
4. Did you encounter this recently, or has this bug always been there: always been there
   
   Steps to reproduce the problem:
   1. use postman.getResponseHeader in test collection to get header value.
   2. If the header value returned from server is as following. The value postman.getResponseHeader get is not full content. It get "; path=/UpdateService" only.

   <http://redfish.dmtf.org/schemas/v1/ServiceRoot.v1_1_1.json>; rel=describedby, </redfish/v1/TaskService>; path=/Tasks, </redfish/v1/Chassis>; path=/Chassis, </redfish/v1/SessionService/Sessions>; path=/Links/Sessions, </redfish/v1/Managers>; path=/Managers, </redfish/v1/EventService>; path=/EventService, </redfish/v1/JsonSchemas>; path=/JsonSchemas, </redfish/v1/Systems>; path=/Systems, </redfish/v1/Registries>; path=/Registries, </redfish/v1/configurations>; path=/Oem/Ami/Configurations, </redfish/v1/SessionService>; path=/SessionService, </redfish/v1/AccountService>; path=/AccountService, </redfish/v1/UpdateService>; path=/UpdateService

   
   Please help to look into this issue
   Note. This issue can't reproduce in POSTMAN

@snk20501 Could you confirm that this still works correctly with v5.3.1 of the Postman app? I'll dig deeper into the header fetch issue in the meantime. 😄

[snk20501]

@kunagpal The version I use is v5.3.0 and it works correctly. Thank you for looking into this problem. :)

[LeonardoGonzales]

I am also having the same issue.

[kunagpal]

@LeonardoGonzales Which version of Newman are you on? You can find this with newman -v.

[LeonardoGonzales]

Hello @kunagpal,
Thank you for the quick feedback.
I am using version 3.8.3 as well. I installed it using npm (npm install -g newman)

[LeonardoGonzales]

Hello @kunagpal,
postman.getResponseHeader is having the same issue in postman application for linux as well.
I downloaded Postman-linux-x64-5.3.2.tar.gz, installed my machine and faced the same error.
Google chrome application version 5.3.0 works for me.

[zhak]

The issue is reproducible in stand-alone Postman v.5.5.0

[borodaalex]

Google chrome application version 5.4.0 does not have this issue, reproducible in desktop version v.5.5.0

[kunagpal]

@snk20501 @LeonardoGonzales @zhak @borodaalex Could you try the following snippet out and let me know if it works for you?

pm.response.headers.one('my_header_name');

Hi guys, I have same issue,

• Ubuntu 16.04
• standalone Postman 5.5.0

response has following headers (pretty view):

Server →xxxxxxxx-xxxxx
Set-Cookie →APSCOOKIE_9539865665021864916="0%260"; path=/; expires=Tue, 06-Feb-1968 18:34:11 GMT
Set-Cookie →VDOM_9539865665021864916="0%260"; path=/; expires=Tue, 06-Feb-1968 18:34:11 GMT
Set-Cookie →log_filters="0%260"; path=/log/; expires=Tue, 06-Feb-1968 18:34:11 GMT
Set-Cookie →log_type="0%260"; path=/log/; expires=Tue, 06-Feb-1968 18:34:11 GMT

Set-Cookie →ccsrftoken="0%260"; path=/; expires=Tue, 06-Feb-1968 18:34:11 GMT

for single value header all looks good:
postman.getResponseHeader('server') ----> "xxxxxxxx-xxxxx"

but for multi-value header like set-cookie we are receiving last element of array, at index 9:
postman.getResponseHeader('Set-Cookie') ----> "ccsrftoken="0%260"; path=/; expires=Tue, 06-Feb-1968 18:30:59 GMT"

also

pm.response.headers.one('Set-Cookie').value;----> "ccsrftoken="0%260"; path=/; expires=Tue, 06-Feb-1968 19:36:57 GMT"

So the clue is that getResponseHeader works incorrect and return last value of multivalue header
This function should return an array of all values for given header name

My workaround for a moment is to use

// print all Set-Cookie header values
pm.response.headers.all()
    .filter(headerObj => { return headerObj.key == "Set-Cookie";})
    .forEach(headerObj => {
        console.log(headerObj.key +": "+headerObj.value)
    })

BR, Karol

@kunagpal I try following script but still get the same result. The POSTMan version is the latest v5.5.2.
pm.response.headers.one('my_header_name');

My question is sort of related to this:
Is there a way to actually parse out 1 value inside a given header
example: postman gives me this response header

X-Pagination →{"TotalCount":6,"PageSize":5,"CurrentPage":1,"TotalPages":2,"PreviousPageLink":null,"NextPageLink":"http://localhost/v1/accounts?searchQuery=nam&pageNumber=2&pageSize=5"}

How do I extract TotalCount and its value?

[LeonardoGonzales]

@kdp88 did you try it:
var pageHeader = JSON.parse(postman.getResponseHeader('X-Pagination') );
console.log(pageHeader.TotalCount);

thank @ekarpie, your "work around" worked very well for me

Best Regards

Leo

[kdp88]

@LeonardoGonzales you are the man dude, that worked flawlessly
how about extracting the TotalCount key and not the value.

[LeonardoGonzales]

for(var key in pageHeader){
console.log('Key'+key +' value: '+ pageHeader[key])
}

[kdp88]

@LeonardoGonzales 2 for 2

I LIKE IT THANKS MAN!

So the debate is ... should we have a polymorphic function return signature for headers? i.e. return string for single and array for multiple. That may break many current use cases across Postman and Newman.

Or find a way to add another function that takes care of this / extra param to indicate allowing multi-value (and make all returns array when that param is set to true -> including for single value)?

So, what happens with query string duplication? @kamalaknn
