I am building a chatbot using Dialogflow, and I deployed the cloud function using inline editor to firebase.

However, compared to V1 there is no javascript SDK to interact with the API. I'm stuck and I cannot find anything helpful in the docs.

Can you please share some example code on how to interact with the dialogflow API using angular ou any j framework ?

Thanks !

I tried to read the dialogflow doc especially the part about http requests. I tried some code with simple http post request which didn't work.

There is no concrete example on stackoverflow.

You can use Dialogflow Rest APIs, You need to generate access token with Google cloud sdk (scope: cloud platform, dialogflow)

  public df_client_call(request) {
    var config = {
      headers: {
        'Authorization': "Bearer " + this.accessToken,
        'Content-Type': 'application/json; charset=utf-8'
      }
    };   
   return this.http.post(
      'https://dialogflow.googleapis.com/v2/projects/' + environment.project_id +
      '/agent/sessions/' + sessionId + ':detectIntent',
      request,
      config
    )
  }

In the request you have to pass,

{
    queryInput: {
        text: {
            text: action.payload.text,
            languageCode: 'en-US',
        },
    }
}

sessionId => unique Id for your user 

const googleAuth = require('google-oauth-jwt');

getToken: async function() {
    return new Promise((resolve) => {
        googleAuth.authenticate(
            {
                email: config.googleClientEmail,
                key: config.googlePrivateKey,
                scopes: ['https://www.googleapis.com/auth/cloud-platform'],
            },
            (err, token) => {
                resolve(token);
            },
        );
    });
},

  • Thanks a lot for you answer, however I'm working with cloud functions deployed to firebase, and I don't want my user to be logged! do you have an idea on how to achieve it ? – TK06 Jul 30 '19 at 06:21
  • session id is something that just need to be unique for user you can define – Nikhil Savaliya Jul 30 '19 at 08:26
  • ok great understood, just a last question. I have some issues installing gcloud sdk to generate the access token, is there any package like in nodejs to generate the token ? https://gist.github.com/weikangchia/d5bb0aa1466407c86692ba00d8f16332 ? thanks so much – TK06 Jul 31 '19 at 09:37
  • thank for your help. For this we will need to set up another server while we are working on firebase. I will try to install gcloud and give it a try. You can see an example of react-native implementation https://www.npmjs.com/package/react-native-dialogflow ! Thanks for your help :) – TK06 Jul 31 '19 at 10:11
