Hi Everyone, I am using following code to get tweets “only tweets”, but getting error:
string access_token;
string tweets;
String keyencoded = EncodingUtil.urlEncode('CYXp886M6g04xwouOHLYg4UJf','UTF-8');
String secretkeyencoded = EncodingUtil.urlEncode('5qC4A3JZDF8you0VtKx95AJqROlXi2oihTkJgVNNsv8pVQ2cjT', 'UTF-8');
String sFinal = keyencoded + ':' + secretkeyencoded;
Blob headerValue = Blob.valueOf(sFinal);
HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.twitter.com/oauth2/token');
req.setMethod('POST');
String authorizationHeader = 'Basic ' + EncodingUtil.base64Encode(headerValue);
req.setHeader('Authorization', authorizationHeader);
req.setBody('grant_type=client_credentials');
Http http = new Http();
HTTPResponse res = http.send(req);
JSONParser parser = JSON.createParser(res.getBody());
while(parser.nextToken() != null)
{
if(parser.getCurrentToken() == JSONToken.FIELD_NAME)
{
String fieldName = parser.getText();
parser.nextToken();
if(fieldName == 'access_token')
{
access_token = parser.getText();
}
}
}
Http http1 =new Http();
HttpRequest request=new HttpRequest();
request.setEndpoint('https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=virendersehwag');
request.setMethod('GET');
string authorizationHeader1 ='Bearer'+access_token;
request.setHeader('Authorization',authorizationHeader1);
HTTPResponse response=http1.send(request);
if(response.getStatusCode()==200)
{
Map<string,object>results=(Map<string, Object>)JSON.deserializeUntyped(response.getBody());
List<object>a=(List<object>)results.get('text');
system.debug(results);
system.debug(a);
}
