I have set up Google Drive UI integration with my web app. When a user chooses to create a new file in Drive using my app, they are sent to
https://[mysite]?state={"folderId": "...", "action": "create", "userId":"..."}
I am signed in to multiple Google accounts (A and B) in my browser.
Account A opts to create a file, and is sent to my app with "userId": "[A's user id]" in the url.
However, with the gapi.auth2 JS library:
authInstance.signIn()
// Listen for sign in, and then:
authInstance.currentUser.get().getAuthResponse().access_token
Returns an access token for Account B.
This causes 404 errors when I try to create a file in folderId, which is only accessible to Account A.
How can my app authenticate with Google as the specific userId that opted to create a file?
The docs for Drive UI Integration do not seem to cover this issue, and the docs for Google Sign-In for Websites do not (as far as I can tell) provide a way to specify which account I want to sign in with (except through broad filters like "use a specific G Suite domain").
Update: The HTTP Google OAuth docs allow the client to specify a login_hint, which is an "email address or sub identifier" – it is not entirely clear what a "sub identifier" is. And, strangely, the Javascript API docs imply that login_hint is a response parameter, not something I can set.
Update 2 userId is an opaque Google-provoded integer value that I don't recognise. My app, Including the Drive upload, is fully client-side in JS and has no long-term data storage.
I created a website for my Students Organization.
On that website there is a page where I list all the people who helped organize our Activities. Theres a picture of every member there.
To get the images, I used their facebook profile pictures.
I used http://graph.facebook.com/USERNAME/picture?height=250&width=250
This code did work a few days ago, but now the images dont seem to load. I followed the url and got a JSON object:
{
"error": {
"message": "(#803) Cannot query users by their username (user.name)",
"type": "OAuthException",
"code": 803
}
}
So it seems to me that facebook might have changed their security... (after googling I found out about some changes in their API 2.0 but I didnt fully understand that..)
This link does still seem to work if you have the userID, but I'm unable to get that userID because of the same error message through graph.facebook.com...
Is there still a way to get facebook profile pictures of people on your website or did facebook totally block this off??
Any help is appreciated!
If you want to use the data, you'll need to implement Facebook Login for your website, where the users can give their permissions to your app to use their data.
The username field is no longer accessible with the Graph API v2.0. There are at least 5-10 questions on this on StackOverflow today.
Look at the docs:
https://developers.facebook.com/docs/apps/changelog#v2_0
Okay what I want is to post to the Facebook Page as an Page(This is developing mode application only viewable to ne).
I have done with Facebook login.
So basically I ask for 2 permissions and they are
Manage Pages
Publish Pages
I can post to the page using the Facebook graph explorer tool but can't via my Javascript code.
Here is the code that I write using JS. This code is written inside a function.
FB.api('me/accounts', function(response){
token = response.data[0].access_token;
post_with_token(token);
});
function post_with_token(token){
var message = $('#post_body').html();
var page_id = 'page_id';
FB.api('page_id/feed', 'post',
{ message : message,
access_token : token},
function (response){
console.log(response);
});
The error object in the console says this
message: "(#200) The user hasn't authorized the application to perform this action"
Both the apps My and Graph explorer have the same permissions granted.Is any new permission to be asked. I am unable to figure out what exactly the problem is.Correct me if I am wrong anywhere.
I got the answer that I posted below but didn't got why I need additional permission.?
publish_pages has only been introduced with Graph API version 2.3.
Before that, publish_actions was used to allow posts on pages by the page as well – now with v2.3, they have made that into two separate permissions. publish_actions is for everything you publish as/in the name of a user, and publish_pages is for publishing as a page.
Graph API Explorer has API version 2.3 selected by default – that is why your call was successful there. Most likely, with your own API call from your JS code, you did not use v2.3, but specified a lower API version when initializing the JS SDK.
So just specify version: 'v2.3' in your FB.init parameters (see Basic Setup section in JS SDK docs), and it should work fine with publish_pages.
Okay I solved the problem . I have to ask for publish_actions permission also. So I asked through the Login Dialog and used the same code as above to post to the page!
The error implies exactly what it says. They've designer their API so it's not going to let you post without proper authorization first.
Facebook provides a guide on how to give proper authorization to your registered app
I'm creating a web page which pulls all posts for certain hashtag from Twitter, Instagram, and Facebook.
I'm trying to get facebook posts by hashtag and show those posts in my web page, and trying to use graph API javascript SDK for it. Twitter and instagram was easier... but facebook is actually giving me some challenge.
I see there's a documentation here:
https://developers.facebook.com/docs/graph-api/reference/hashtag
Javascript SDK says
FB.api(
"/{hashtag-id}",
function (response) {
if (response && !response.error) {
/* handle the result */
}
}
);
What's supposed to go into "/{hashtag-id}"?
I've tried putting in the real hashtag (something like %23fail) instead of {hashtag-id} but it seems to give this error:
"(#803) Some of the aliases you requested do not exist: #fail"
I've also played around with the Graph API explorer, but I can't seem to be able to pull any posts by the hashtag.
It seems to be working on the facebook website.
https://www.facebook.com/hashtag/fail
is that possible for developers to do using Graph API?
Thanks.
I'm trying to figure out a way to display data collected from Google Analytics on my web site. I'm using NopCommerce, and I want to display this information/statistics in a view in the Admin Section.
There might be many ways to achieve this, and after searching the web I found some examples using JavaScript, but I couldn't find a good tutorial for this.
I have also looked into integrating Google Analytics with C#, and I found this example: http://biasecurities.com/2012/02/using-the-google-analytics-api-with-asp-net-mvc/#comment-1310
A demo project can be downloaded from GitHub here: https://github.com/jgeurts/Analytics-Example
However the demo project doesn't seem to work as the google URL (https://www.google.com/analytics/feeds/accounts/default) is no longer in use.
As I'm using a MVC application it would be preferable to make this happen by applying the Google Analytics logic within a Controller and displaying it in a view. Or something like that.
Google provides a query tool to experiment with here, so it shouldn't be to hard extracting data from Google Analytics and display the data on the website: https://ga-dev-tools.appspot.com/explorer/
Has anyone been able to successfully display Google Analytics data on their website?
In case some one else is having the same problem here's what I did and it pretty much answers the question.
1.
Here is the basic code for a API client that access data from Google Analytics via your Google Service Account. https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#service_account
In order to make this application work you need to have several things ready before you start coding.
*Google Analytics Account - once registered a "tracker" code is generated for you to put on each webpage you want to track. You may not see any statistics right away and it can take up to 24h before any statistics are shown in the Google Analytics Dashboard.
An OAuth Authorisation (API-Key) with CLIENT_ID, CLIENT SECRET and EMAIL ADRESS (This is not your normal email but a service account email that is created for you when you make an OAuth Authorisation).
console.developers.google.com/
A serverkey, can also be created here: console.developers.google.com/.
You can also create a browser key, haven't bothered with that though and don't know what it does.
Finally you need a certificate key. Your application will only be able to access your Google Analytics account by using the key and credentials. The key is an encrypted p.12 file. You can find the key in https://code.google.com/apis/console/.
Here is a guide for the key: http://www.pimcore.org/wiki/display/PIMCORE/Setup+Google+Analytics+Reporting+with+OAuth2+Service+Accounts+(since+1.4.6)
2.
Now that you have all keys and credentials you need it is time to start looking at the code I linked in "1". Here is the basic for it again: https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#service_account
Create a console application and implement the code above.
Note: your not making a "Google Plus service" so you have to change those parts for "AnalyticsService". Go to manage nuget and install packages:
Google Apis Core Library
Google Apis Client Library
Google Apis Auth Client Library
Google Apis Analytics.v3 Library
Google GData Client (This provides properties used to query data, metrics, demensions etc)
Google GData Extensions Library
Analytics
Might forgot something but here are the namespaces I use:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Analytics.v3;
3
Finally, here's is some of my code. Note I'm creating a new Analytics as supposed to "new ServiceAccountCredentials" as in the code from Google. That's the main difference:
Retrieve data from Google Analytics API with .NET, multiple metrics?
With this I'm able to access and query data from Google Analytics account. The best part is that you don't have to log in to Google for this as the key and credentials gives you access to the account data directly.
I will migrate this code to MVC now I might make an update later on for how to implement this Analytics client in Mvc.
This document explains how to get Google Access tokens and use them to get Google Analytics data to be displayed in our websites.
Example: A live example is available in
https://newtonjoshua.com
Note: Use the same Gmail account for all the below steps.
STEP 1: Set Up Google Analytics
Follow the below steps to set up Google Analytics on your website
Sign in to your Analytics account.
Select the Admin tab.
Select an account from the drop-down menu in the ACCOUNT column.
Select a property from the drop-down menu in the PROPERTY column.
Under PROPERTY, click Tracking Info -> Tracking Code.
To collect data, you must copy and paste the Analytics tracking code
into the source code on every web page you wish to track.
Once you have the JavaScript tracking code snippet for your
property, copy the snippet exactly without editing it.
Paste your tracking code snippet (unaltered, in its entirety) before
the closing </head> tag on every web page on your site you wish to
track.
Once you have successfully installed Analytics tracking, it may take
up to 24 hours for data such as traffic referral information, user
characteristics, and browsing information to appear in your reports
Refer to:
https://support.google.com/analytics/answer/1008080?hl=en
https://analytics.google.com
STEP 2: Get Tokens
Google Project:
To create a Google Cloud Platform project, open the Google Developers Console (https://console.developers.google.com) and click Create Project.
Enable OAuth 2.0 API access:
Your application will need to access user data and contact other Google services on your behalf. Use OAuth 2.0 to grant your app API access.
To enable that, you need a client ID:
Open the Google API Console Credentials page (https://console.developers.google.com/apis/credentials).
From the project, drop-down and select your project.
Select Create credentials and choose OAuth client ID.
Under Application type, select Web application, enter a Name and
set the Restrictions by entering JavaScript origins, Redirect URIs to point the website where you are planning to display the data, and then click Create.
Make note of the OAuth 2.0 client_id and client_secret. You will need them to configure the UI.
Get Authorization code:
Enter in browser:
https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/analytics.readonly&response_type=code&client_id={{
client_id}}&redirect_uri={{redirect_uri }}
&approval_prompt=force&access_type=offline
You will get redirected to
{{redirect_uri }}?code=={{authorization_code}}#
Get Refresh Token:
Send a POST request, possibly via a REST console to
https://www.googleapis.com/oauth2/v3/token?code={{authorization_code}}
&client_id={{client_id}}&client_secret={{client_secret}}
&redirect_uri={{redirect_uri }}&grant_type=authorization_code
You will get a JSON response with
{"refresh_token": refresh_token}
You can use the refresh token to get access token to access to Google APIs.
Get the Access Token:
Send a POST request to,
https://www.googleapis.com/oauth2/v3/token?client_id={{client_id}}
&client_secret={{client_id}}
&grant_type=refresh_token&refresh_token={{refresh_token}}
You will get a JSON with access_token in the response.
{access_token: {{access_token}}}
Example:
var access_token = '';
function getAccessToken(){
$.post('https://www.googleapis.com/oauth2/v3/token', {
client_id: {{client_id}},
client_secret: {{client_secret}},
grant_type: 'refresh_token',
refresh_token: {{refresh_token}}
}, function (data, status) {
if (status === 'success') {
access_token = data.access_token;
// Do something eith the access_token
}
else {
console.error(status);
}
});
}
Check Token validity:
Send a POST request to,
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={{access_token}}
Example:
function checkValidity() {
$.post('https://www.googleapis.com/oauth2/v1/tokeninfo', {
access_token:{{access_token}}
}).done(function (data, status) {
if (status === 'success') {
console.debug(data.expires_in);
var check = false;
check = data.hasOwnProperty('expires_in');
if (check) {
// Token is valid
}
if (!check) {
getAccessToken();
}
}
else {
console.debug(status);
}
})
.fail(function (data) {
console.error(data);
getAccessToken();
});
}
Step 3: Fetch Data
Embed API:
The GA Embed API is a JavaScript library that allows you to easily create and embed your GA dashboard on your website in a matter of minutes.
Refer to https://developers.google.com/analytics/devguides/reporting/embed/v1/getting-started.
Query Explorer:
Visit Embed API Query Explorer and authorize
https://ga-dev-tools.appspot.com/query-explorer/
Select the view for which you want to fetch the data.
Select the required metrics and dimensions.
Example:
Get Country Data (I want to know the number of users accessing my website from each country).
To get that data, select the metrics as 'users' and the dimensions as 'country'.
Click on Run Query.
You will find the analytics data for the query displayed in a table.
Copy the API Query URI. And add access_token={{access_token}} to the URI.
Example:
https://www.googleapis.com/analytics/v3/data/ga?ids={{ids}}&start-date=2015-07-01&end-date=today&metrics=ga%3Ausers&dimensions=ga%3Acountry&access_token={{access_token}}
Send POST request to the URIs to get the data in your browser.
Example:
function gaGetCountry() {
$.get('https://www.googleapis.com/analytics/v3/data/ga?' +
'ids={{ids}}' +
'start-date=2015-07-01&' +
'end-date=today&' +
'metrics=ga%3Ausers&' +
'dimensions=ga%3Acountry&' +
'sort=ga%3Ausers&' +
'filters=ga%3Ausers%3E10&' +
'max-results=50' +
'&access_token=' + {{access_token}},
function (data, status) {
if (status === 'success') {
// Display the Data
drawRegionsMap(data.rows);
} else {
console.debug(status);
}
});
}
Step 4: Display Data
Now we have gathered the data. Finally we have to display them on our website.
"Display live data on your site" is the title of Google Charts. And that is what we are going to do.
Refer to https://developers.google.com/chart/.
The following example will draw a GeoChart in the div with id='countryChart'.
// Draw country chart
function drawRegionsMap(data) {
var head = data[0];
head[0] = 'Country';
head[1] = 'Users';
for (var i = 1; i < data.length; i++) {
var d = data[i];
d[1] = Number(d[1]);
}
var chartData = google.visualization.arrayToDataTable(data);
var options = {
title: 'My Website is viewed from,',
domain: '{{Country Code eg: IN for India}}',
tooltip: {
textStyle: {
color: 'navy'
},
showColorCode: true
},
legend: {
textStyle: {
color: 'navy',
fontSize: 12
}
},
colorAxis: {
colors: ['#00FFFF', '#0000FF']
}
};
var chart = new google.visualization.GeoChart(document.getElementById('countryChart'));
chart.draw(chartData, options);
}
Refer to https://newtonjoshua.com to view the above example in action.
I'd recommend to use the new Google APIs Client Library for .NET (currently in beta). Information about the Analytics API can be found here. Note that the Client Library for .NET (google-api-dotnet-client) supersedes the .NET library for the Google Data API (google-gdata).
Unfortunately, there is no sample code available yet from Google (see this issue) but this question on SO should help.
If you don't want to login every time you access Analytics data, you can use OAuth 2.0 authorization with offline access. You have to grant initial access to your web application, though. This requires you to login once but you can use a refresh token later on.
To date, the easiest solution is to create a report of your Google Analytics data in Google Data Studio (free, native connector to GA), and share that report to embed in an <iframe>
See details on https://support.google.com/datastudio/answer/7450249?hl=en
You get
flexible vizualisation
security and control on the data being shared
0 code nor maintenance
result is being cached for better performance
I spent a couple of days trawling the Internet to get some sample ASP.NET code with no luck. I used Koffe14's method for authentication, and also Linda Lawton's excellent ASP.NET analytics example.
I've posted the code on my website. It's not MVC, but it might help other people who need to get data from Google analytics into an ASP.NET web page using the v3 Google API.
Check out embeddedanalytics.com (disclaimer - I work with them).
This is a simple yet powerful solution geared for people that don't want deal with learning the GA API and then having to link it to visualization (e.g. charts/graphs).
Basically define your charts and embed a snippet of code where you want the chart to show. We also support mechanisms so that it is easy to integrate into a custom built CMS or other web portal.
