I'm trying to connect to Ubuntu One from YQL to get Ubuntu One data as YQL table.
This requires to generate with Javascript the XML as outlined in http://developer.yahoo.com/yql/guide/yql-execute-chapter.html.
The only implementation in JS I found is on maemo.org for a QT client (http://goo.gl/ztuiw). Being in the YQL environment allows to use y.rest instead of XMLHttpRequest. There are example in php (http://askubuntu.com/questions/54185/ubuntu-one-oauth-login-from-php) and in Phyton (on the Ubuntu One site).
Basically the code should:
1) Create a new token in Ubuntu SSO (login.ubuntu.com)
2) Tell Ubuntu One about that new token
3) Use that new token to sign a request to the Ubuntu One files API
The code for the YQL is on github (https://github.com/emaV/labs/tree/master/oneubuntu-js).
<code>
// Include the OAuth libraries from oauth.net
y.include("http://oauth.googlecode.com/svn/code/javascript/oauth.js");
y.include("http://oauth.googlecode.com/svn/code/javascript/sha1.js");
function getToken(user, pass, token_name) {
var url = "https://login.ubuntu.com/api/1.0/authentications";
var uri = url + "?ws.op=authenticate&token_name=" + encodeURIComponent(token_name);
var header_auth = 'Basic ' + y.crypto.encodeBase64(user + ":" + pass);
// Get authentication
var resp = y.rest(uri).header('Accept', 'application/xml').header('Authorization', header_auth).get().response;
// cast to string
var secrets = {
consumerKey: String(resp.consumer_key),
consumerSecret: String(resp.consumer_secret),
token: String(resp.token),
tokenSecret: String(resp.token_secret)
};
return secrets;
}
function registerToken(secrets, user) {
var url = "https://one.ubuntu.com/oauth/sso-finished-so-get-tokens/" + user;
reg = oAuthRequest(url, secrets);
return reg;
}
function oAuthRequest(url, secrets, method, range) {
if(!method) method = "GET";
var message = {
action: url,
method: method,
parameters: [
["oauth_consumer_key", secrets.consumerKey],
["oauth_token", secrets.token],
["oauth_version","1.0"]
]
};
OAuth.setTimestampAndNonce(message);
OAuth.SignatureMethod.sign(message, secrets);
var auth = OAuth.getAuthorizationHeader("", message.parameters);
return = y.rest(url).header('Authorization', auth).get().response;
}
// Main
var OAuth;
var token_name = "Ubuntu One @test";
// 1 ) Get the token using HTML authentication
var secrets = getToken(email, pwd, token_name); // works
// 2) Register the token
var reg = registerToken(secrets, email); // works
// 3) Use API
var APIurl = "https://one.ubuntu.com/api/account/";
resp = oAuthRequest(APIurl, secrets);
</code>
Steps 1) and 2) seems ok but 3) still return "Invalid access token". The result from step 2 reads:
<log>oAuthRequest - url: https://one.ubuntu.com/oauth/sso-finished-so-get-tokens/emanuele.quinto@gmail.com</log>
<url execution-start-time="843" execution-stop-time="3236"
execution-time="2393" proxy="DEFAULT"><![CDATA[https://one.ubuntu.com/oauth/sso-finished-so-get-tokens/emanuele.quinto@gmail.com]]></url>
<log>oAuthRequest (https://one.ubuntu.com/oauth/sso-finished-so-get-tokens/emanuele.quinto@gmail.com) - resp: </log>
<log>ok 0/1
</log>
So everything seems fine, but:
<log>oAuthRequest - url: https://one.ubuntu.com/api/account/</log>
<url execution-start-time="3257" execution-stop-time="3783"
execution-time="526" http-status-code="401"
http-status-message="UNAUTHORIZED" proxy="DEFAULT"><![CDATA[https://one.ubuntu.com/api/account/]]></url>
<log>oAuthRequest (https://one.ubuntu.com/api/account/) - resp: </log>
<log>Invalid access token: PZvMjSewNiphQkDTtFAexTcOkrxbVSKPNBhOqOnFSeZUaLmmAt
</log>
I'm not sure if the issue is related to YQL but given the log doesn't seems so. |
