Hello,
Could some one help me out to post a tweet from js. As there is no SDK/Nu-get package. I have tried and after some work Im able to get token and all the stuff. I stuck bound at POSTwhere it always return me with 400 or 401 errors with messages Bad Authentication data,215 or Unable to authenticate you ,32.
Where as GET for https://api.twitter.com/1.1/users/show.json’ is working fine. Unable to cope up with post.
Below is my code snippet.
function posttoTwitter() {
//https://dev.twitter.com/docs/api/1.1/post/statuses/update_with_media
//https://dev.twitter.com/docs/api/1.1/post/statuses/update
var status = encodeURIComponent("Explore show Case metro app from the store");
var twitterURL = "https://api.twitter.com/1.1/statuses/update.json";
var ClientID = "ZQBIILZI9PiA8aKG1RjNHw";
var ClientSecret = "zKJ9l9qutrdIhCM7rVS7Rd5PPRfU3gCshJrMQ3s00";
var callbackURL = "http://itshowcase.cloudapp.net/";
// Acquiring a request token
var timestamp = Math.round(new Date().getTime() / 1000.0);
var nonce = Math.random();//Windows.Security.Cryptography.CryptographicBuffer.generateRandomNumber();//
nonce = Math.floor(nonce * 1000000000);
// Compute base signature string and sign it.
// This is a common operation that is required for all requests even after the token is obtained.
// Parameters need to be sorted in alphabetical order
// Keys and values should be URL Encoded.
var sigBaseStringParams = "oauth_callback=" + encodeURIComponent(callbackURL);
sigBaseStringParams += "&" + "oauth_consumer_key=" + ClientID;
sigBaseStringParams += "&" + "oauth_nonce=" + nonce;
sigBaseStringParams += "&" + "oauth_signature_method=HMAC-SHA1";
sigBaseStringParams += "&" + "oauth_token=" + userAccessToken;
sigBaseStringParams += "&" + "oauth_timestamp=" + timestamp;
sigBaseStringParams += "&" + "oauth_version=1.0";
sigBaseStringParams += "&" + "status=" + encodeURIComponent(status);
var sigBaseString = "POST&";
sigBaseString += encodeURIComponent(twitterURL) + "&" + encodeURIComponent(sigBaseStringParams);
var keyText = encodeURIComponent(ClientSecret) + "&" + encodeURIComponent(userAccessTokenSecret);
var keyMaterial = Windows.Security.Cryptography.CryptographicBuffer.convertStringToBinary(keyText, Windows.Security.Cryptography.BinaryStringEncoding.Utf8);
var macAlgorithmProvider = Windows.Security.Cryptography.Core.MacAlgorithmProvider.openAlgorithm("HMAC_SHA1");
var key = macAlgorithmProvider.createKey(keyMaterial);
var tbs = Windows.Security.Cryptography.CryptographicBuffer.convertStringToBinary(sigBaseString, Windows.Security.Cryptography.BinaryStringEncoding.Utf8);
var signatureBuffer = Windows.Security.Cryptography.Core.CryptographicEngine.sign(key, tbs);
var signature = Windows.Security.Cryptography.CryptographicBuffer.encodeToBase64String(signatureBuffer);
var dataToPost = "OAuth oauth_callback=" + encodeURIComponent(callbackURL) + "\",oauth_consumer_key=\"" + ClientID + "\", oauth_nonce=\"" + nonce + "\",oauth_signature=\"" + encodeURIComponent(signature) + "\",oauth_signature_method=\"HMAC-SHA1" + "\",oauth_timestamp=\"" + timestamp + "\",oauth_token=\"" + userAccessToken + "\", oauth_version=\"1.0\"";
var response = sendTweetRequest(twitterURL, dataToPost, encodeURIComponent(status));
}
function sendTweetRequest(url, authzheader, requestbody) {
try {
var request = new XMLHttpRequest();
request.open("POST", url, false);
request.setRequestHeader("Authorization:", authzheader);
request.send(requestbody);
if (request.status != "200") {
console.log(request);
}
return request.responseText;
} catch (err) {
WinJS.log("Error sending request: " + err, "Web Authentication SDK Sample", "error");
}
}
Tried a lot… could some one help me on this please.
