Problem with SOAP with Attachment

[Moxom160]

Hello

First i want to say that most of my problems i can solve while scripting by looking at the forum or in the help file but im stuck on this specific problem. I have been writing scripts to consume Web services and this works fine when its just plain XML responses. I work on a project now where i need to consume a SOAP response with an Attachment. I can make the plain SOAP call and get a response as well but i dont know how to handle the multipart and binary data. I have tried ADODB.Stream to write the data to a file but this just writes everything. I would be very grateful if someone could point me into the right direction.

Please find below the Request and the Response i get at the momen

Moxom160,

.SaveToFile(@ScriptDir&'\captcha.arf', 2)

As the Forum rules are clear on the fact that we do not support anything that deals with CAPTCHAs, could you please explain what this line is doing.

Hello Melba

I think there is missunderstanding. I was trying around different bits of code and found one snipped where the file name was set to captcha.png. since i was only testing i did not change the file name to something else. Im not planning on dealing with CAPTCHAs or anything like this.

To prove my indention please find below a link to the service im trying to access. Im trying to retrieve webex recordings via the NBR(network based recording) API.

https://developer.cisco.com/site/webex-developer/develop-test/nbr-web-services-api/api-functions.gsp#downloadNBRStorageFile

Sorry for the missunderstanding.

regards

[Melba23]

Moxom160,

Fine - but please be careful which "snippets" you use in future.

You need to parse returned data to extract the attachment. It shouldn't be hard since it's standard MIME.

Can you post the exact response? Parts are missing from your post.

[Moxom160]

Hello trancexx

The response i posted above is every thing i get in human readable form .after the last ------=_Part_5_987625235.1444159091234 and the content ids it streams down binary data.

I have tested today to stream the reponse via ADODB.Stream to a local file and this works fine. The only think im stuck at on how to seperate the binary data from the top 30 lines of response. Im only interested in the binary which i require to generate the recording file.

I have attached a response so you can have look at it. Thank you already for looking at this.

test.xml

[trancexx]

That file misses the most important data to process it correctly - the original MIME header.

Does this help further? I have this from the API doc from Cisco.

Does this work?

It should extract "attachment" with Content-Id <16F8B262D5B9C561D8899E638D3B3D8C> from "test.xml" to file named "YourAttachment.txt". All located in the script's folder.

Hello trancexx

thanks for the script but running the above on my XML gives me "no such attachment exists".  I have tried different Content-ID's to see if i get different result but its always the same error.

Hello trancexx

I told you that the file you posted here isn't full. It's missing header part where boundary is defined.

[trancexx]

Something like this:

Content-Type: Multipart/Related; boundary=----=_Part_39_1838099744.1444244895679; type=text/xml;

 

[trancexx]

My guess is that you're missing headers. For your original code it could be:

With $oDATA
    .Type = 2
    .Open()
    .WriteText($objHTTP.getAllResponseHeaders() & $objHTTP.ResponseText)
    .SaveToFile(@ScriptDir & '\captcha.arf', 2)
    .Close()
EndWith

 

[Moxom160]

Hello trancexx

I have just tried you suggestions and you were absolutly right i need to get the full headers and formating corrected. Its working now perfectly. thank you for the support.

Have day.

As always, again I learned something interesting, as I wast thought that IMessage is only for EML , now I re read MSDN doc for this.
Thanks
