Missing the response_type when using decision page in implicit mode

[wascou]

When I use the Implict mode, using the decisionPage options triggers an error :

{
error: "invalid_request",
error_description: "Missing required parameter: response_type"
}

It seems that the following line is missing :

response_type: req.oauth2.req.type,

in the following block code in oauth2-loopback.js

if (options.decisionPage) {
        var urlObj = {
          pathname: options.decisionPage,
          query: {
            response_type: req.oauth2.req.type,
            transactionId: req.oauth2.transactionID,
            userId: req.oauth2.user.id,
            clientId: req.oauth2.client.id,
            scope: req.oauth2.req.scope,
            redirectURI: req.oauth2.redirectURI
          }
        };
        return res.redirect(url.format(urlObj));
      }

Your client should send a request to the authorization endpoint as follows:

https://localhost:3001/oauth/authorize?client_id=123&redirect_uri=https://localhost:3001/server-side-app.html&response_type=token&scope=demostate=123

Please the response_type param MUST be token.

Hi,

I tried what you said but got another error : client_id is required. I set it, and then 'redirect_uri' error popped. It seems that their is a wrong mapping at this point.

I actually drop this feature and use the regular decisionView option that works well.

Thank you.

If you take the request @raymondfeng posted as an example, you see it requires a client_id in it's params. The client_id is unique identifier of the application you should have created.

Actually, I tested this in the following way :

• Set up a classic gateway project
• Add the decisionPage options
• Use implict mode with client included inside the project

I got the error on each of the params and it seems that clientId is forwarded instead of _clientid.

I drop this configuration as it was not working and I use the dialogView instead and set every parameters I needed.

Thank you for the answer !
