I want to know if I can use Google spreadsheet as a back-end database for my Blogger website. I have done so in past using Google Fusion Tables.
I can use Web Apps as well by using a custom domain to direct to their long URL. But when I update the script, I have to deploy the web app. This changes the long URL, so I need to update my redirection.
Is there a way to access & update a Google Spreadsheet from my website.
You cannot do this with Blogger.
However, you can do this with Sites.
If you setup a spreadsheet like this:
Then you create a web app from that like this:
var sheet = SpreadsheetApp.openByUrl("YOUR URL").getSheetByName("LinkConfig");
function getDataIndex(key) {
var Keys = sheet.getRange(2, 1, sheet.getMaxColumns(), 1).getValues().map(function(row) {return row[0]});
for (var i=0; i<Keys.length; i++) {
if (Keys[i]==key) return i+2;
}
}
function getData(key) {
return sheet.getRange(getDataIndex(key), 2).getValue();
}
function test() {
Logger.log(getData("url1"));
Logger.log(getData("url2"));
}
function webApp(key) {
//Get contents from target URL
var content = UrlFetchApp.fetch(getData(key)).getContentText();
return HtmlService.createHtmlOutput(content); //Returns new page with the same content
}
function doGet(e) {
if (e.parameter.key != null && e.parameter.key != undefined) {
return webApp(e.parameter.key);
} else {
return HtmlService.createHtmlOutput("<h1>Error! You didn't specify a 'key' parameter</h1>");
}
}
And deploy it.
Now, as long as you don't change that one URL (meaning you don't edit this main "config" webapp, you are able to change values on the spreadsheet and access the pages linked there by passing the key.
To use it in Sites, add an Embed element and set the URL to : yourwebappurl?key=keyvalue
I am using $this->redirect to redirect from one action to another
$this->redirect(array('site/payment','bookingID'=>$bookingID,'orderID'=>$model->quoteNo,'amount'=>$rent));
But I don't why it showing parameter in url
https://www.siteurl.com/bookingID/5/orderID/123456/amount/220.00
How do I hide my data from user?
You can do it using sessions. You can access current Session with Yii::$app->session. You can send those parameters in session.. For Example
public function actionOne() {
// Check if the Session is Open, and Open it if it isn't Open already
if (!Yii::$app->session->getIsActive()) {
Yii::$app->session->open();
}
Yii::$app->session['bookingID'] = $bookingID;
Yii::$app->session['orderID'] = $model->quoteNo;
Yii::$app->session['amount'] = $rent;
Yii::$app->session->close();
$this->redirect(['site/payment']);
}
public function actionTwo() {
// Then you can get those values like this...
$bookingID= Yii::$app->session['bookingID'];
$orderID= Yii::$app->session['orderID'];
$amount= Yii::$app->session['amount'];
// do whatever you want..
}
I am trying to get my friend name and ids with Graph API v2.0, but data returns empty:
{
"data": [
]
}
When I was using v1.0, everything was OK with the following request:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
But now I cannot get friends!
In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
Although Simon Cross's answer is accepted and correct, I thought I would beef it up a bit with an example (Android) of what needs to be done. I'll keep it as general as I can and focus on just the question. Personally I wound up storing things in a database so the loading was smooth, but that requires a CursorAdapter and ContentProvider which is a bit out of scope here.
I came here myself and then thought, now what?!
The Issue
Just like user3594351, I was noticing the friend data was blank. I found this out by using the FriendPickerFragment. What worked three months ago, no longer works. Even Facebook's examples broke. So my issue was 'How Do I create FriendPickerFragment by hand?
What Did Not Work
Option #1 from Simon Cross was not strong enough to invite friends to the app. Simon Cross also recommended the Requests Dialog, but that would only allow five requests at a time. The requests dialog also showed the same friends during any given Facebook logged in session. Not useful.
What Worked (Summary)
Option #2 with some hard work. You must make sure you fulfill Facebook's new rules: 1.) You're a game 2.) You have a Canvas app (Web Presence) 3.) Your app is registered with Facebook. It is all done on the Facebook developer website under Settings.
To emulate the friend picker by hand inside my app I did the following:
Create a tab activity that shows two fragments. Each fragment shows a list. One fragment for available friend (/me/friends) and another for invitable friends (/me/invitable_friends). Use the same fragment code to render both tabs.
Create an AsyncTask that will get the friend data from Facebook. Once that data is loaded, toss it to the adapter which will render the values to the screen.

//parse /me/invitable_friend
this.facebookId = jsonObject.getString("id");
this.name = jsonObject.getString("name");
// Handle the picture data.
JSONObject pictureJsonObject = jsonObject.getJSONObject("picture").getJSONObject("data");
boolean isSilhouette = pictureJsonObject.getBoolean("is_silhouette");
if (!isSilhouette) {
this.pictureUrl = pictureJsonObject.getString("url");
} else {
this.pictureUrl = "";
}
this.invitable = true;
} else {
// Parse /me/friends
this.facebookId = jsonObject.getString("id");
this.name = jsonObject.getString("name");
this.available = true;
this.pictureUrl = "";
}
isValid = true;
} catch (JSONException e) {
Log.w("#", "Warnings - unable to process Facebook JSON: " + e.getLocalizedMessage());
}
}
}
Facebook has revised their policies now. You can’t get the whole friendlist anyway if your app does not have a Canvas implementation and if your app is not a game. Of course there’s also taggable_friends, but that one is for tagging only.
You will be able to pull the list of friends who have authorised the app only.
The apps that are using Graph API 1.0 will be working till April 30th, 2015 and after that it will be deprecated.
See the following to get more details on this:
User Friends
Facebook Application Development FAQ
In Swift 4.2 and Xcode 10.1:
If you want to get the friends list from Facebook, you need to submit your app for review in Facebook. See some of the Login Permissions:
Login Permissions
Here are the two steps:
1) First your app status is must be in Live
2) Get required permissions form Facebook.
1) Enable our app status live:
Go to the apps page and select your app
https://developers.facebook.com/apps/
Select status in the top right in Dashboard.
Submit privacy policy URL
Select category
Now our app is in Live status.
One step is completed.
2) Submit our app for review:
First send required requests.
Example: user_friends, user_videos, user_posts, etc.
Second, go to the Current Request page
Example: user_events
Submit all details
Like this submit for all requests (user_friends , user_events, user_videos, user_posts, etc.).
Finally submit your app for review.
If your review is accepted from Facebook's side, you are now eligible to read contacts, etc.
As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.
this is against Facebook policy, so depending on the country where you live, this may not be legal
you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
this is bypassing the OAuth concept
on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API
Sample implementation using WatiN:
class FacebookUser
{
public string Name { get; set; }
public long Id { get; set; }
}
public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
Settings.Instance.MakeNewIeInstanceVisible = false;
using (var browser = new IE("https://www.facebook.com"))
{
try
{
browser.TextField(Find.ByName("email")).Value = email;
browser.TextField(Find.ByName("pass")).Value = password;
browser.Form(Find.ById("login_form")).Submit();
browser.WaitForComplete();
}
catch (ElementNotFoundException)
{
// We're already logged in
}
browser.GoTo("https://www.facebook.com/friends");
var watch = new Stopwatch();
watch.Start();
Link previousLastLink = null;
while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).LastOrDefault();
if (lastLink == null || previousLastLink == lastLink)
{
break;
}
var ieElement = lastLink.NativeElement as IEElement;
if (ieElement != null)
{
var htmlElement = ieElement.AsHtmlElement;
htmlElement.scrollIntoView();
browser.WaitForComplete();
}
previousLastLink = lastLink;
}
var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([0-9]+))");
foreach (var link in links)
{
string hovercard = link.GetAttributeValue("data-hovercard");
var match = idRegex.Match(hovercard);
long id = 0;
if (match.Success)
{
id = long.Parse(match.Groups["id"].Value);
}
users.Add(new FacebookUser
{
Name = link.Text,
Id = id
});
}
}
return users;
}
Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.
Try /me/taggable_friends?limit=5000 using your JavaScript code
Or
try the Graph API:
https://graph.facebook.com/v2.3/user_id_here/taggable_friends?access_token=
If you are still struggling with this issue on a development mode.
Follow the same process as mentioned below:
create a test app of your main app,
create test users, automatically install app for test users and assign them 'user_friend' permission.
Add your test users as a friend with each other.
I followed the same process after going through alot of research and finally it worked.
In the Facebook SDK Graph API v2.0 or above, you must request the user_friends permission from each user in the time of Facebook login since user_friends is no longer included by default in every login; we have to add that.
Each user must grant the user_friends permission in order to appear in the response to /me/friends.
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
fbLoginManager.logIn(withReadPermissions: ["email","user_friends","public_profile"], from: self) { (result, error) in
if (error == nil) {
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if fbloginresult.grantedPermissions != nil {
if (fbloginresult.grantedPermissions.contains("email")) {
// Do the stuff
}
else {
}
}
else {
}
}
}
So at the time of Facebook login, it prompts with a screen which contain all the permissions:
If the user presses the Continue button, the permissions will be set. When you access the friends list using Graph API, your friends who logged into the application as above will be listed
if ((FBSDKAccessToken.current()) != nil) {
FBSDKGraphRequest(graphPath: "/me/friends", parameters: ["fields" : "id,name"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil) {
print(result!)
}
})
}
The output will contain the users who granted the user_friends permission at the time of login to your application through Facebook.
{
data = (
{
id = xxxxxxxxxx;
name = "xxxxxxxx";
}
);
paging = {
cursors = {
after = xxxxxx;
before = xxxxxxx;
};
};
summary = {
"total_count" = 8;
};
}
I'm shortening my "news" page's long URLs by using this code.
var api_key = 'AIzaSyCNGB0ddmvRkn5h************';
var docURL = document.URL;
function makeRequest() {
var request = gapi.client.urlshortener.url.insert({
'resource': {'longUrl': docURL}
});
request.execute(function(response) {
var newItem = {
url : response.id
}
$(".googlURL").html($("#shareButtons").tmpl({url : response.id , title : $('.newsDetail h3').text()));
});
}
function load() {
gapi.client.setApiKey(api_key);
gapi.client.load('urlshortener', 'v1', makeRequest);
}
this code creates goo.gl URL perfectly.
When someone visit the news details, it creates a shorten url automatically even any url is not created before.
But i would like to see the URLs in my goo.gl panel.
When i visit http://goo.gl/ with my account, i can not see how many URLs created and how many times they visited.
Is there a way to do this?
Thanks
I have found a solution as below about your question. May be that can help you
If you have already created a shortened goo.gl url just type .info at
the end (e.g. goo.gl/url.info)
I would be able to retrieve HTML markup of what is stored in Twitter Card (https://dev.twitter.com/docs/cards).
Up until now I used TweetSharp library to retrieve tweets from some user's timeline. But, what is not surprising, because cards are new thing, it is not included.
Does anyone know, if it is possible to access card (data cached by Twitter crawler) with API?
The Twitter cards themselves are not exposed through the Twitter API.
What you'll need to do is make a request to the URL mentioned and examine the <head> element to see if they have the Twitter Card info in there.
Twitter apis do not provide the twitter-card info out of the box. You can extract the card info for a url by looking it up in its html. Below code in csharp gets card image src from the url-
public static TweetMedia[] GetTwitterCardDetails(string url)
{
string HTML;
using (var wc = new WebClient())
{
HTML = wc.DownloadString(url);
}
var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(HTML);
HtmlNode element = doc.DocumentNode.SelectSingleNode("//meta[#name='twitter:image:src']");
if (element != null)
{
return new TweetMedia[] { new TweetMedia { url=url, media_url_https = element.Attributes["content"].Value, type = TweetTypes.TweetType.Photo.ToString() } };
}
return null;
}
