Twitter
Integration with Application
Dependencies:
Ø To achieve automation of twitter, we will use a third party
component called TweetSharp that can
also be integrated to our application using Manage NuGet Packages from Visual Studio.
Ø Once we
have installed the TweetSharp in our
project, we need to follow one more step and that is to register our app to
Twitter.
Register your Website on Twitter.com:
Everything you need to know can be
found on the Twitter Developers Portal (Of Course you need a Twitter Account)
Ø After Login to your Twitter account
follow below process:-
Step-1:
Step-2:
After clicking above link it
will take you to the below page:
Step-3:
Click on "Create New App" which will open like this below:
Step-4:
Completely Fill Out the "Application Details" Form. The
Callback URL field, you can leave it blank.
Step-5:
After filling the “Application Details”
accept the agreement and click on “Create
your Twitter Application” button
which will create your twitter application.
Step-6:
After your Application is created your Consumer Key/Secret are created,
which are needed for authorization. So note it for future use.
Step-7:
In the Application Settings the Application Type needs to be set to
"Read and Write". You can
change the type by clicking “Permissions”
tab like below.
Step-8:
After
creation of application, you will be taken to “App management” web page where click on “Keys and Access Tokens” tab.
Here you can see “Consumer Key”, “Consumer Secret” and you can generate “Access Token” also.
Step-9:
Here you can generate
Access Token by clicking “Create my
access token” button it will generate your “Access Token” and “Access
Token Secret” like below.
Step-10:
Now copy following from the
above page
·
Consumer Key
·
Consumer Secret
·
Access Token
·
Access Token Secret
Step-10:
Using C# code to Tweet:
Ø
First add a new web form page in your Solution named it as
MessagePosting.aspx
Ø
Now write HTML markup in MessagePosting.aspx page that will create
a user interface.
HTML Markup:
<body>
<form id="form1" runat="server">
<div>
<p>Twitter message:<br />
<asp:TextBox ID="txtMessage" runat="server" TextMode="MultiLine" Rows="5" Columns="50" /></p>
<p>Twitter Image:<br />
<asp:FileUpload runat="server" id="FileUpload1" /></p>
<asp:Button ID="btnTwit" runat="server" Text="Tweet" OnClick="btnTwit_Click" /><hr />
<asp:Label ID="lblResult" runat="server" EnableViewState="false" />
</div>
</form>
</body>
Clicking on the Tweet button, will call following
method of the code behind page.
Step-11:
C# Code:
Ø Now import
these two namespaces:
using
TweetSharp;
using TwitterOAuth;
Ø Write c#
code in button’s OnClick event i.e.- OnClick="btnTwit_Click"
protected void btnTwit_Click(object sender, EventArgs e)
{
string key = "T0CQ6WQ9ITAjwzhfeHWpOUOFM";
string secret = "
9x09s4PN1NzjWx6XkTKZIICTLKqjLF0Zze5QdqIz9HPT86r1pW";
9x09s4PN1NzjWx6XkTKZIICTLKqjLF0Zze5QdqIz9HPT86r1pW";
string token = "
836141164331950080-6h5bdSPg6ZpJYyNeT5AlmCZxjKTUGFT";
836141164331950080-6h5bdSPg6ZpJYyNeT5AlmCZxjKTUGFT";
string tokenSecret = "
6FHUXMAZD8a042VqRblPrRNKRfvxa5VC9sjkR8nsFbjPf";
6FHUXMAZD8a042VqRblPrRNKRfvxa5VC9sjkR8nsFbjPf";
string message = txtMessage.Text.Trim();
//check
if file is there, upload it
string imagePath = string.Empty;
if (FileUpload1.HasFile)
{
string fileName = System.IO.Path.GetFileName(FileUpload1.FileName);
imagePath = Server.MapPath("~/Images/" +
fileName);
FileUpload1.SaveAs(imagePath);
}
var service = new TweetSharp.TwitterService(key, secret);
service.AuthenticateWith(token,
tokenSecret);
//Tweet
with image
if (imagePath.Length > 0)
{
using (var stream = new FileStream(imagePath, FileMode.Open))
{
var result = service.SendTweetWithMedia(new SendTweetWithMediaOptions
{
Status = message,
Images = new Dictionary<string, Stream> { { "Images", stream
} }
});
lblResult.Text =
result.Text.ToString();
}
}
else // just message
{
var result = service.SendTweet(new SendTweetOptions
{
Status = message
});
lblResult.Text =
result.Text.ToString();
}
}
Ø In the
above code, first we are creating variables for keys and secrets to be used
from twitter app registrations page. Then we are checking if the user is
uploading the file to tweet, if yes then uploading the file into
"Image" folder otherwise simply authenticating to Twitter service
using keys and secrets.
Ø If image
is being uploaded, we are calling SendTweetWithMedia() method to
send the message as well as image as stream to the twitter otherwise we are
calling SendTweet() method
that simply sends the plain text message to the twitter to tweet.
Ø Now once
you go to your twitter account, you can cross check that all your tweets are
available on twitter website.
Conclusion:
Even
if Twitter has its own API that can be consumed directly to tweet however using
TweetSharp makes it easy for us to
call methods and pass necessary arguments. TweetSharp
is a wrapper around Twitter API that exposes methods and property to simplify
tweeting.
