Passport-wechat-auth

Passport strategies for authenticating with [wechat] using OAuth 1.0a and OAuth 2.0.

This module lets you authenticate using wechat in your Node.js applications. By plugging into Passport, wechat authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-wechat-auth

Usage of OAuth 2.0

Configure Strategy

The wechat OAuth 2.0 authentication strategy authenticates users using a wechat account and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a app ID, app secret, and callback URL.

passport.use(new GoogleStrategy({
    appId: WECHAT_APP_ID,
    appSecret: WECHAT_APP_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/wechat/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ openid: profile.openid }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'wechat' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/wechat',
  passport.authenticate('wechat'));

app.get('/auth/wechat/callback', 
  passport.authenticate('wechat', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });
