Re: How do download a binary file as a stream with Zinc?

Hi Mariano,

(I can't access the file you gave as an example, probably an extra #username:password: is needed)

You are making it more difficult than it has to be: this gives you the bytes you want

ZnClient new
        get: 'http://zn.stfx.eu/zn/string.fuel'.

With some better system parameters this becomes

ZnClient new
        systemPolicy;
        beOneShot;
        accept: ZnMimeType applicationOctetStream;
        url: 'http://zn.stfx.eu/zn/string.fuel';
        get.

But what you really want is something like:

ZnClient new
        systemPolicy;
        beOneShot;
        accept: ZnMimeType applicationOctetStream;
        url: 'http://zn.stfx.eu/zn/string.fuel';
        contentReader: [ :entity | FLMaterializer materializeFromByteArray: entity contents ];
        get.

You can experiment with #streaming: true but that is only worth it for large (MB) files. IMHO.

HTH,

Sven

Hi Sven. Indeed, this last piece of code was what I was searching for. 

However, my "experiment" was to be able to directly revive test failures form Jenkins. 

But it turns out that it is not possible to have each .fuel separated...instead we have one big zip for all of them.

So at the end what Sean did is to have a zip with all .fuel files and the image itself. And he even wrote a UI for that. So my experiment ended there regarding Zinc.

anyway, at least I learnt how to do it. 

thanks Sven!
