Currently trying to tweet from matlab. I have set up an app in twitter and then used the API keys respectively as below. But when I log into my twitter account, I am unable to see the tweet posted.

Kindly help me.

consumerkey = 'xxxx';
consumersecret = 'yyyy';
accesstoken = 'zzzz';
accesstokensecret = 'tttt';
c=twitter(consumerkey,consumersecret,accesstoken,accesstokensecret);
c.StatusCode
baseurl = 'https://api.twitter.com/1.1/account/settings.json';
tweetString = "Hello";
d = postdata(c,baseurl,'status',tweetString)

Output: -

ResponseMessage with properties:

StatusLine: 'HTTP/1.1 200 OK'

StatusCode: OK

Header: [1×25 matlab.net.http.HeaderField]

Body: [1×1 matlab.net.http.MessageBody]

Completed: 0

Edited by Guillaume: Replaced keys/secrets that allows anybody to impersonate you on twitter.

Do not post secret keys on a public forum! This allows anybody to tweet on your behalf. I would recommend that you immediately requirest new keys from twitter as you do not know who may have seen the keys before I edited them. See Twitter's help on Securing keys and tokens

What is the content of Header and Body? Again, if it contains any sensitive information, edit that before posting it.

Thanks for your advice Guilaume.

This is what I am able to see when I call the HeaderField anf MessageBody. Am I missing anything?

HeaderField with properties:

Name: []

Value: []

MessageBody with properties:

Data: []

Payload: []

ContentType: []

ContentCoding: [0×0 string]

在 MATLAB Online 中打开

According to this example, the base url to post tweet is

baseurl = 'https://api.twitter.com/1.1/statuses/update.json';

not the one you're using.

I don't have the datafeed toolbox (nor a twitter account) to test.

Clearly, one of your key or secret is no longer valid, so twitter reject your post. It's no longer a problem with the syntax. It's an authentication issue.
