Authorize URI Extension

Generate Authorize URI.

Install

``
yarn add @rc-ex/authorize-uri
`

Usage

`ts
import RingCentral from '@rc-ex/core';
import AuthorizeUriExtension from '@rc-ex/authorize-uri';

const rc = new RingCentral(...);
const authorizeUriExtension = new AuthorizeUriExtension();
await rc.installExtension(authorizeUriExtension);
const authorizeUri = authorizeUriExtension.buildUri({
state: 'hello',
redirect_uri: 'https://example.com',
});
`

For a working sample, please check this
test case.

PKCE

Ref:
https://medium.com/ringcentral-developers/use-authorization-code-pkce-for-ringcentral-api-in-client-app-e9108f04b5f0

First and foremost, you should not specify client secret in your project, that's
the whole point of PKCE.

Secondly, specify code_challenge_method: 'S256':

`ts
const authorizeUri = authorizeUriExtension.buildUri({
state: "hello",
redirect_uri: "https://example.com",
code_challenge_method: "S256",
});
`

And you should save the codeVerifier:

`ts
const codeVerifier = authorizeUriExtension.codeVerifier;
`

You may need to persist codeVerifier in case browser web page refreshes.

And when you make the authorize API call, remember to specify code_verifier:

`ts
await rc.authorize({
code: "...",
redirect_uri: "...",
code_verifier: codeVerifier,
});
`

Base Authorization URI

Optionally, you can specify baseAuthorizationUri as parameter to the
constructor of this extension. If it's not specified,
${rc.rest.server}/restapi/oauth/authorize is used as baseAuthorizationUri`.
