I am building a google contextual gadget in it i use the following code to load a page:
var params = {};
url = "http://example.com:2057/tasks/create";
params[gadgets.io.RequestParameters.CONTENT_TYPE] = gadgets.io.ContentType.JSON;
params[gadgets.io.RequestParameters.AUTHORIZATION] = gadgets.io.AuthorizationType.SIGNED;
params["OAUTH_SERVICE_NAME"] = "HMAC";
params[gadgets.io.RequestParameters.METHOD] = gadgets.io.MethodType.GET;
gadgets.io.makeRequest(url, function(response)
{
if (response.data && response.data.RedirectUrl)
HandleLogin(response.data.RedirectUrl);
else if(response.text)
{
showOneSection('main');
$('#main').append(response.text);
}
else
ShowDebug(response);
}, params);
The call does not reach my server. and when i try reaching the url in a browser it returns fast.
what can be the problem? how can i trouble shoot it?
Thanks
I finally found the problem.
when making a signed request you have to first obtain a consumer key + secret key.
see http://www.google.com/support/forum/p/apps-apis/thread?tid=31db71169fb6fc77&hl=en
you can do that here: https://www.google.com/gadgets/directory/verify
without the keys google is unable to sign the request (although one would expect a proper error message).

I have read many posts, all the Google documentation I can find and tried many iterations of the following and still can't get an access and refresh token. I do get an authorization code but can't seem to get that to trade for the access and refresh tokens.
if(authCode == null || authCode.equals("")) {
String url = "https://accounts.google.com/o/oauth2/v2/auth?"
+ "scope=https://mail.google.com/&"
+ "response_type=code&"
+ "redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&"
+ "client_id=" + clientId +
"&access_type=offline";
URI uri = new URI(url);
logger.debug("URI for auth is: " + uri);
if (Desktop.isDesktopSupported() && Desktop.getDesktop().isSupported(Desktop.Action.BROWSE)) {
Desktop.getDesktop().browse(uri);
}
}
else {
logger.debug("Refreshing");
initRefreshToken();
}
With that, I get an access code I can cut and paste (just testing and trying to get this to work first) in my properties to get the refresh and access token.
In the initRefreshToken() method, the source is like this:
if(refreshToken.equals("")) {
logger.debug("Getting refresh token");
HttpPost post = new HttpPost("https://oauth2.googleapis.com/token");
// add request parameter, form parameters
List<NameValuePair> urlParameters = new ArrayList<>();
urlParameters.add(new BasicNameValuePair("code", authCode));
urlParameters.add(new BasicNameValuePair("client_id", clientId));
urlParameters.add(new BasicNameValuePair("client_secret", clientSecret));
urlParameters.add(new BasicNameValuePair("redirect_uri", "http://localhost:8000/"));
urlParameters.add(new BasicNameValuePair("grant_type", "authorization_code"));
try {
post.setEntity(new UrlEncodedFormEntity(urlParameters));
System.out.println("***** URL: " + urlParameters);
CloseableHttpClient httpClient = HttpClients.createDefault();
CloseableHttpResponse response = httpClient.execute(post);
System.out.println(EntityUtils.toString(response.getEntity()));
}
If this is a second or subsequent time using the code, what will be printed is:
Refersh token:
***** URL: [code=4/1AY0e-g..., client_id=370...i1h2u1s.apps.googleusercontent.com, client_secret=bAOH..., redirect_uri=https://localhost:8000/, grant_type=authorization_code]
{
"error": "invalid_grant",
"error_description": "Bad Request"
}
If the code is run and it's the first time using an authentication code, it will print:
{
"error": "redirect_uri_mismatch",
"error_description": "Bad Request"
}
I read in the Google console that exceptions are made for localhost domains so there's no need to register them. However, if there were a need to register them, it won't let you register them anyway as a domain must be a top level domain you own in order to register it. Therefore, how do I register localhost and/or exchange an authorization code for an access and refresh token in Java?
Thank you for your help.
DaImTo provided a great video about this and in that video and the blog post associated with it, the redirect_uri is listed correctly as: "urn:ietf:wg:oauth:2.0:oob". I didn't find this in the documentation but when I added it to my source code, I got access and refresh tokens as a response. Thank you very much for that help, DaImTo.
I am trying to write a simple electron app to interface with a REST server. The server doesn't have the appropriate certificates. When I try to make a 'GET' request (using fetch()), I get the following error message:
Failed to load resource: net::ERR_BAD_SSL_CLIENT_AUTH_CERT
Fixing the certs is not currently an option. I tried to use the 'ignore-certificates-error' flag (see below). It seems like it should allow me to skip over this error, but it doesn't.
var electron = require('electron');
var app = electron.app
app.commandLine.appendSwitch('ignore-certificate-errors');
...
The result is the same error.
Questions:
I am correct in assuming this options is supposed to help here?
If so, any ideas what I am doing wrong?
Electron version: 1.2.8
Thanks!
You can update your version of electron and use this callback:
app.on('certificate-error', (event, webContents, link, error, certificate, callback) => {
if ('yourURL/api/'.indexOf(link) !== -1) {
// Verification logic.
event.preventDefault();
callback(true);
} else {
callback(false);
}
});
That you going do the fetch to your api with https.
Hello it's my first time doing a sign in process in a mobile app with Titanium and I wonder what information should I save and the best practice to do it?
My server is configured in this way:
The server requires I send a user and password and if the information match it will provide a token session.
This is the code I use for signing in:
function signIn(e) {
//function to use HTTP to connect to a web server and transfer the data.
var sendit = Ti.Network.createHTTPClient({
onerror : function(e) {
Ti.API.debug(e.error);
alert('There was an error during the connection');
},
timeout : 100000,
});
//Here you have to change it for your local ip
sendit.open('POST', 'http://myserver');
var params = {
user : $.txtUsuario.value,
password : $.txtPassword.value
};
sendit.send(params);
//Function to be called upon a successful response
sendit.onload = function() {
var json = this.responseText;
var response = JSON.parse(json);
if (response.success == "true")
{
var landing = Alloy.createController("menu").getView();
$.index.close();
landing.open();
}
else
{
alert(response);
}
};
};
the code above is working, however I do not know how to manage the sign out. I would like my application works like the most apps do, e.g:
You sign in once and after that if you do not close the app you are able to continues using it and even making a request.
Thank you for any explanation.
It depends on your app requirements. for exemple if you will use the token in your app later you can save it as an AppProperty :
Ti.App.Properties.setString('token',yourTokenGoHere);
and in the app starting you can get it back :
var myToken = Ti.App.Properties.getString('token');
and then you can make a test for example if the token is still valid or not :
if(myToken === 'invalidtoken')
youSholdLogin();
else
youCanGoFurther();
and when the user disconnect rest the token to be invalid :
Ti.App.Properties.setString('token', 'invalidtoken');
Just finished breakfast and already hit a snag. I'm trying to call the salesforce REST api from my google sheets. I've written a working script locally in python, but converting it into JS, something went wrong:
function authenticateSF(){
var url = 'https://login.salesforce.com/services/oauth2/token';
var options = {
grant_type:'password',
client_id:'XXXXXXXXXXX',
client_secret:'111111111111',
username:'ITSME#smee.com',
password:'smee'
};
var results = UrlFetchApp.fetch(url, options);
}
Here is the error response:
Request failed for https://login.salesforce.com/services/oauth2/token
returned code 400. Truncated server response:
{"error_description":"grant type not
supported","error":"unsupported_grant_type"} (use muteHttpExceptions
option to examine full response) (line 12, file "Code")
Mind you, these exact parameters work fine in my local python script (putting the key values inside quotations).
Here are the relevant docs:
Google Script: Connecting to external API's
Salesforce: REST API guide
Thank you all!
Google's UrlFetchApp object automatically defaults to a GET request. To authenticate, you have to explicitly set in the options the method "post":
function authenticateSF(){
var url = 'https://login.salesforce.com/services/oauth2/token';
var payload = {
'grant_type':'password',
'client_id':'XXXXXXXXXXX',
'client_secret':'111111111111',
'username':'ITSME#smee.com',
'password':'smee'
};
var options = {
'method':'post',
'payload':payload
};
var results = UrlFetchApp.fetch(url, options);
}
I'm trying to write a front end to an API service with Node JS.
I'd like to be able to have a user point their browser at my node server and make a request. The node script would modify the input to the request, call the api service, then modify the output and pass back to the user.
I like the solution here (with Express JS and node-http-proxy) as it passes the cookies and headers directly from the user through my site to the api server.
proxy request in node.js / express
I see how to modify the input to the request, but i can't figure out how to modify the response. Any suggestions?
transformer-proxy could be useful here. I'm the author of this plugin and I'm answering here because I found this page when looking for the same question and wasn't satisfied with harmon as I don't want to manipulate HTML.
Maybe someone else is looking for this and finds it useful.
Harmon is designed to plug into node-http-proxy https://github.com/No9/harmon
It uses trumpet and so is stream based to work around any buffering problems.
It uses an element and attribute selector to enable manipulation of a response.
This can be used to modify output response.
See here: https://github.com/nodejitsu/node-http-proxy/issues/382#issuecomment-14895039
http-proxy-interceptor is a middleware I wrote for this very purpose. It allows you to modify the http response using one or more transform streams. There are tons of stream-based packages available (like trumpet, which harmon uses), and by using streams you can avoid buffering the entire response.
var httpProxy = require('http-proxy');
var modifyResponse = require('http-proxy-response-rewrite');
var proxy = httpProxy.createServer({
target:'target server IP here',
});
proxy.listen(8001);
proxy.on('error', function (err, req, res) {
res.writeHead(500, {
'Content-Type': 'text/plain'
});
res.end('Something went wrong. And we are reporting a custom error message.');
});
proxy.on('proxyRes', function (proxyRes, req, res) {
modifyResponse(res, proxyRes.headers['content-encoding'], function (body) {
if (body && (body.indexOf("<process-order-response>")!= -1)) {
var beforeTag = "</receipt-text>"; //tag after which u can add data to
// response
var beforeTagBody = body.substring(0,(body.indexOf(beforeTag) + beforeTag.length));
var requiredXml = " <ga-loyalty-rewards>\n"+
"<previousBalance>0</previousBalance>\n"+
"<availableBalance>0</availableBalance>\n"+
"<accuruedAmount>0</accuruedAmount>\n"+
"<redeemedAmount>0</redeemedAmount>\n"+
"</ga-loyalty-rewards>";
var afterTagBody = body.substring(body.indexOf(beforeTag)+ beforeTag.length)+
var res = [];
res.push(beforeTagBody, requiredXml, afterTagBody);
console.log(res.join(""));
return res.join("");
}
return body;
});
});
