Facebook 图 API 长寿命令牌

Question

I am working with Facebook Graph API and I have followed the instruction on the official documentation page to obtain a Long-Lived Token using a previously extracted access token by running the below code

 //Get long-lived access token var longLiveToken = "https://graph.facebook.com/v8.0/oauth/" + req.authInfo + "?grant_type=fb_exchange_token&client_id=" + process.env.FACEBOOK_CLIENT_ID + "&client_secret=" + process.env.FACEBOOK_CLIENT_SECRET + "&fb_exchange_token=" + req.authInfo + "&redirect_uri=http://localhost:4000/"; https.get(longLiveToken, (res) => { console.log('statusCode:', res.statusCode); console.log('headers:', res.headers); res.on('data', (d) => { console.log(d); }); }).on('error', (e) => { console.error(e); });

However I am getting the below error message

'www-authenticate': 'OAuth "Facebook Platform" "invalid_request" "client_secret should not be passed to /oauth

My query is in line with the official documentation, not sure why I am getting this error message or how to go about resolving it

Answer 1

I figured out what is wrong with the code, I passed in wrong params. Below is the correct query

 var longLiveToken = "https://graph.facebook.com/v8.0/oauth/" + "access_token" + "?grant_type=fb_exchange_token&client_id=" + process.env.FACEBOOK_CLIENT_ID + "&client_secret=" + process.env.FACEBOOK_CLIENT_SECRET + "&fb_exchange_token=" + req.authInfo;

Answer 2

You should not provide client_secret value. Try to not provide client parameters. Maybe you're providing wrong uri , or not passing required parameters. It works if you would take a look again.
