Hi Sven, I created the ZnOAuth1DropboxUserAccess with the ZnOAuth1Service and ZnOAuth1ConsumerData instances in it. Then I assigned the accessToken from an inspector. That worked. I was able to read the file from the dropbox with getFile:. Great! I used that code (please note "STON fromString: in contents asString ") save the ZnOAuth1DropboxUserAccess as file: (Path * 'plonk.txt') asFileReference fileStreamDo: [ :stream | STON put: self onStreamPretty: stream ]. Read and create the ZnOAuth1DropboxUserAccess instance and then get contents of the demo file ((Path * 'plonk.ston') asFileReference readStreamDo: [ :in | STON fromString: in contents asString ]) getFile: #( 'demo.txt' ). This is fine. My next question is how can I create an instance of ZnOAuth1Token from WITHIN my application? When I need this ZnOAuth1Token, I am in a subclass of WAComponent. I don't want the user to click at a link like localhost:8100/sso-dropbox. Clicking at a button within my application should send the user directly to the dropbox page to grant access and create the ZnOAuth1Token. Cold you perhaps create a small code example like this renderContentOn: method html anchor script: html jQuery this button; url: '???http://localhost:8100/sso-dropbox???'; with: 'send me to dropbox, create ZnOAuth1Token and return it in some way'.

Hi Sven,
great! The file was created in my dropbox account:-)
And it will be read, updated and written from now on, every time you run the demo.
I will try to use it now in my application and will come back with questions if they occur.
Yesterday I used STON to serialize a ZnOAuth1DropboxUserAccess instance that was created from the demo web app demo.
To make such an instance you use the codes that were also needed to set up the web demo and the 2 part access token that the web app requested and was granted by the user. To access this token, you currently have to inspect/explore the sessions in the ZnServer instance (there will normally only be one) and assign it to the following object (this is all in hack/debug mode):
| data service |
data := ZnOAuth1ConsumerData newForDropbox consumer: 'vqzexpgl5rvzXXX'; consumerSecret: '13uygcdbou8lXXX'; yourself.
service := ZnOAuth1Service new providerAccount: data ; yourself.
ZnOAuth1DropboxUserAccess new oauth1Service: service; yourself.
(And send it #accessToken:).
This will give you a representation like this:
ZnOAuth1DropboxUserAccess { #oauth1Service : ZnOAuth1Service { #providerAccount : ZnOAuth1ConsumerData { #getRequestTokenUrl : ' https://api.dropbox.com/1/oauth/request_token', #authorizeTokenUrl : ' https://www.dropbox.com/1/oauth/authorize', #getAccessTokenUrl : ' https://api.dropbox.com/1/oauth/access_token', #consumer : 'vqzexpgl5rvzXXX', #consumerSecret : '13uygcdbou8lXXX', #accessTokenClass : nil } }, #accessToken : ZnOAuth1Token { #value : 'qdcm6mivqesdXXX', #secret : '39w7r9wqamdgXXX', #sessionid : nil } }
I don't know what the lifetime is of this, but from other apps using Dropbox I am guessing it must be pretty long, even close to infinite. So one day later, with the demo web app long gone and image restarted, I can do this:
('ZnOAuth1DropboxUserAccess.ston' asFileReference readStreamDo: [ :in | STON fromString: in ]) getFile: #( 'demo.txt' ).
And it just works.
Now, we have to work out a way to make this flow easier and secure at the same time.
Thank you very much.
We wrote this so that others can use it, so we are happy with other developers trying out our stuff.
Thanks for testing and for the feedback.
Sven

Sven,
could you provide a simple code fragment which shows how to write and how to read a file from the smalltalk image to the connected dropbox app folder?
The whole API is not (yet) implemented.
https://www.dropbox.com/developers/reference/api
Have a look at ZnOAuth1TwitterUserAccess.
If I find more time, I might try myself.
GET is pretty straightforward, for PUT or POST you will have to supply a ZnEntity of a specific mime-type with bytes or a string.
Note that for file access the host is different.
I added a bit more Dropbox API and a little demo accessing files.
There is now #manipulateDemoFile: which will try to access a file called 'demo.txt' and read an id out of it. If found the file is written again, with the id increased and some other fields updated as well. If the file did not exist, it is created with id 1. All this happens automatically if you access /sso-dropbox and log in. You'll get the updated id in the web page and you'll see your Dropbox client doing a local update immediately!
Here are the details (http://mc.stfx.eu/Zinc-HTTP-Components):

This should get you started.
Note that it is not necessary to log in each time: the access token is valid until you get an unauthorized response. With the access token and the consumer data you can create service objects separate from the web app that did the setup.
HTH,
Sven

Hi Sven, hi Jan,
thank you. I am one step further now but there must be something else missing to load. I failed with my current image, so I tried the following:
I took a fresh image - the Pharo 1.4. one click app from the pharo homepage ( http://gforge.inria.fr/frs/download.php/31258/Pharo-1.4-14557-OneClick.zip )
Then I loaded seaside 3.0 (from the welcome screen - MetacelloConfigurationBrowser open).
After that, I loaded
Gofer it url: 'http://mc.stfx.eu/ZincHTTPComponents'; package: 'ConfigurationOfZincHTTPComponents'; load.
And then the bleeding Edge version ConfigurationOfZincHTTPComponents project bleedingEdge load: 'SSO'.
Then this was possible: (ZnServer startDefaultOn: 8100) logToTranscript; debugMode: true; delegate: (ZnSSOServerDelegate new dropboxData: (ZnOAuth1ConsumerData newForDropbox
consumer: 'my appdata';
consumerSecret: 'my appdata';
yourself);
yourself).
No I tried in my browser localhost:8100/sso-dropbox
Then I got a walkback in my Image: No secure socket stream class set
or available
Well, the error says it all: you need TLS/SSL support. As is noted in
https://github.com/svenvc/docs/blob/master/zinc/zinc-sso-paper.md#installati...
You can get Zodiac to work in 1.4
Don't forget that you also need the plugin next to your VM !
In Pharo 2.0 Zodiac is included by default the latest VM's there
should have the plugin.
But in 2.0 it will be slightly more difficult to load Seaside, but it does work.
Sorry, but all this is still a bit in motion, hopefully you will keep trying.
==>> I do not have the class ZdcSecureSocketStream in my Image self secureSocketStreamClass is Nil in

Can you tell me what is missing to load?

Hi Sven,
after loading:
Gofer it url: 'http://mc.stfx.eu/ZincHTTPComponents'; package: 'ConfigurationOfZincHTTPComponents'; load.
ConfigurationOfZincHTTPComponents project latestVersion load: 'SSO'.
The ZnOAuth1ConsumerData does not have a method called newForDropbox (but >>newForGoogle and >>newForTwitter). Also, ZnSSOServerDelegate does not have a method >>dropboxData: (but facebook, twittter and google)
Did I miss something?
Yes and no. The latest stable version of the configuration does not yet include the Dropbox code. The following will load what is called bleedingEdge, the very latest version of everything, regardless of its release status.
ConfigurationOfZincHTTPComponents project bleedingEdge load: 'SSO'.
Sorry about that.

If anyone is interested, I can write another email explaining how you can run this demo for yourself on your own account.
How to run the Dropbox code yourself:
1. Get yourself a free Dropbox account at http://www.dropbox.com
2. Install some client software on one or more of your computers (Mac, Windows, Linux) or devices (iOS [iPhone, iPad, iPod], Android, BlackBerry, Kindle Fire) and move some files around to get a feel for the service.
3. When you give other applications access to (part of) your Dropbox files, you can check that at https://www.dropbox.com/account#applications
4. Define your own app that will try to access Dropbox files. Go to https://www.dropbox.com/developers (Developer home) and start defining a new app by clicking the 'Create an app' button at https://www.dropbox.com/developers/apps - start with the access type 'App folder'.
5. The two important elements you need are the 'App key' and 'App secret', make sure to copy them correctly.
6. Get the very latest code in your image (we develop in Pharo 2.0, but 1.4 or even 1.3 should work - SSL has to be fully operational).
Gofer it url: 'http://mc.stfx.eu/ZincHTTPComponents'; package: 'ConfigurationOfZincHTTPComponents'; load.
ConfigurationOfZincHTTPComponents project latestVersion load: 'SSO'.
7. Start a Zn server with an appropriate delegate, configured for your app
(ZnServer startDefaultOn: 8100) logToTranscript; debugMode: true; delegate: (ZnSSOServerDelegate new dropboxData: (ZnOAuth1ConsumerData newForDropbox
consumer: 'vqz-app-key-zoca';
consumerSecret: '13u-app-secret-8l006';
yourself);
yourself).
(The above is a demo setup limited to Dropbox, the other demos are
not configured and won't work).
8. Go to http:://localhost:8100/sso-dropbox and click the link to
log in - you will be transferred to Dropbox to log in (if you aren't already) and asked to authorise your demo app, after which Dropbox will redirect you back to your app.
9. Once back in your app, sso-dropbox-callback
(#ssoDropboxCallback:) will access your account info and list the app root folder, which will then be shown.
10. For the rest of the API, (currently not yet implemented), see
https://www.dropbox.com/developers/reference/api - you don't have to worry about the whole authentication thanks to Zinc-SSO.
We would love for others to try this (as well as the other Zinc-SSO
options, Google, Facebook, Twitter) out, in their own projects, and to provide actual feedback and generally help improve the code and documentation.
As always, May the Source be with you!
Sven
PS: The demo app is not (yet) a production app: only you and up to
5 explicitly listed users can use it. You have to apply for production status later on. Also, the whole ZnSSOServerDelegate code is a demo, for an actual project, it would be best to extract the necessary parts out of it, reusing the underlying Zinc-SSO-OAuth1-Core framework.
