I’m attempting to use Application Only Authentication in Google Script to access the Twitter Search API.
I followed the setup instructions on the Application Authentication page and have successfully received and stored my Bearer Token.
However, whenever I try to make a GET request to the Search API, it returns this response:
{errors=[{code=86, message=This method requires a GET or HEAD.}]}
However, I do include a GET in my method and using Google Script’s UrlFetchService worked successfully with a POST for obtaining the Bearer Token.
I’ve checked in the forums and the only mentions of Code 86 have a slightly different response:
{errors=[{code=86, message=This method requires a DELETE or POST.}]}
This user on StackOverflow had a similar error, but his fix was in Java which couldn’t be used in Google Script. And this person had the same error in R although they weren’t even able to obtain the bearer token in the first place.
Below is the code that successfully retrieves and stores a Bearer Token
function getToken() {
// STEP 1 - ENCODE CONSUMER KEY AND SECRET
var consumerKey = PropertiesService.getScriptProperties().getProperty("twitterConsumerKey");
var secret = PropertiesService.getScriptProperties().getProperty("twitterSecret");
var encoded_consumerKey = encodeURIComponent(consumerKey);
var encoded_secret = encodeURIComponent(secret);
var encoded_joined = encoded_consumerKey+':'+encoded_secret;
var base64_joined = Utilities.base64Encode(encoded_joined);
Logger.log(base64_joined);
//STEP 2 - OBTAIN A BEARER TOKEN
var bearer_url = 'https://api.twitter.com/oauth2/token';
var options = {
"method": "post",
"headers":{
"Authorization": "Basic "+base64_joined,
"Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"
},
"payload": {
"grant_type": "client_credentials"
}
}
var response = UrlFetchApp.fetch(bearer_url, options);
var data = JSON.parse(response.getContentText());
var access_token = PropertiesService.getScriptProperties().setProperty("access_token", data.access_token);
}
And below is the code for when I use that Bearer Token and receive the “This method requires a GET or HEAD” error.
function checkTwitter(){
//SEARCH API
var bearer_token = PropertiesService.getScriptProperties().getProperty("access_token");
var search_url = 'https://api.twitter.com/1.1/search/tweets.json';
var search_term = 'http://www.theverge.com/2015/10/6/9463931/tom-hanks-lauren-student-id';
var encoded_search = encodeURIComponent(search_term);
var payload = {
"q": encoded_search,
"result_type": "recent",
"count": "10"
};
var options = {
"method": "get",
"payload": payload,
"headers":{
"Authorization": "Bearer "+bearer_token,
"Content-Type": "application/x-www-form-urlencoded;charset=UTF-8",
"Accept-Encoding": "gzip"
},
"followRedirects": true,
"muteHttpExceptions": true
};
var response = UrlFetchApp.fetch(search_url, options);
var data = JSON.parse(response.getContentText());
}
Any help or insights would be greatly appreciated!
