title: React JS - IBM Watson Personality InsightsV3 Token Auth - CORS error
body: <p>I have been attempting to implement the Watson PersonalityInsightsV3 API into my React JS app. In order to circumvent the CORS error that arises when using credentials I have a flask/python server making a request for the token. I then use fetch inside my React JS files to receive the token and attempt to pass it to my Watson profile request. I am still getting the CORS error despite this and am not sure how to complete the request with the token.</p>
  
  <pre><code> try { axios.get('http://project1-m6.c9users.io:8080/token')
          .then(result =&gt; {     console.log('AAA ' + result.data)
  
  
              var  PersonalityInsightsV3 = require('watson-developer-cloud/personality-insights/v3');
              var personality_insights = new PersonalityInsightsV3({
                  username: 'myname',
                  password: 'mypassword',
                  version_date: '2017-10-13',
                  headers: { 'X-Watson-Authorization-Token': result.data }
              });
  
  
                 personality_insights.profile(
                  {
                      content: input,
                      content_type: 'text/plain',
                      consumption_preferences: true,
                      raw_scores: true
                  },
                  function(err, response) {
                      if (err) {
                          console.log('error:', err);
                      } else {
                          console.log(JSON.stringify(response, null, 2));
                          _this.props.history.push(
                              {pathname: '/personality', state: {result:JSON.stringify(response, null, 3)}})
                      }
                  }
              );
          }
          );
      } catch(e) { console.log(e) };
