使用 twitter4j 发布推文

Question

I have a twiiter app with:

// Bearer token

// API key

// API key secret

// Access token:

// Access token secret:

and Read, Write, and Direct Messages permissions

I use a ConfigurationBuilder class to configure Twitter4J programmatically in Java:

ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
            .setOAuthConsumerKey("IX9qalH5azhSk61ZoFMiL83Jg")   // API key
            .setOAuthConsumerSecret("tidoT2GgVZE3B3txDb64tuinlv0wZHbKesX5bNIcjPWpxmcYcs") // API key secret
            .setOAuthAccessToken("1345093646195010258-goY3W4oyqSltGFSUNPwJy8pSjSmfI5") // Access token:
            .setOAuthAccessTokenSecret("ijkpYB8sacVcBdvKHOnh95Y3QRITzD3c4Uq8nUUMLTN8O"); //Access token secret:
    TwitterFactory tf = new TwitterFactory(cb.build());
    return tf.getInstance();

But I have this error when I try to publish:

401:Authentication credentials (https://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.
{"request":"\/1.1\/media\/upload.json","error":"Read-only application cannot POST."}

I send the tweets from an Ubuntu server, already sync ( https://vitux.com/how-to-sync-system-time-with-internet-time-servers-on-ubuntu-20-04/ )

Answer 1

From this response below, I think you are using this API .

401:Authentication credentials (https://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.
{"request":"\/1.1\/media\/upload.json","error":"Read-only application cannot POST."}

As there is an error message like below you need to create a Twitter application with Read & Write permissions. For more details about error messages, check this .

Read-only application cannot POST.

Here is the official developer document about app permissions . Change this: to this:

I hope, this is clear enough.
