微信OAuth

提示

Superagent需要Node版本大于6

使用方法

获取code所需的redirect_url，已经encode

var wxoauth = require('./lib/oauth')
var redirect_url = new wxoauth.wechatOAuth(params).getRedirectUrl();
return res.redirect(redirect_url);

params = {
    redirect_url: REDIRECTURL,  // 回调地址
    app_id: APPID // appid
}

获取userinfo

1、scope: snsapi_base 2、scope: snsapi_userinfo

new wxoauth.wechatOAuth(params).getAccessToken();

Tips：scope为base时，getAccessToken执行完返回数据；scope为userinfo时，执行完getAccessToken后会继续执行getUserInfo方法获取到用户信息后再返回数据

params = {
    app_id: APPID, // appid
    app_secret: APPSECRET, // appsecret
    callback: callback(result), // 业务代码函数，返回openid&用户信息
    scope: snsapi_base/snsapi_userinfo, // 可选，默认snsapi_userinfo
    code: code // 从微信获取的code
}

例子：

var express = require('express');
var router = express.Router();

var wxoauth = require('wx-oauth-base');

var config = {
    appid: xxx,
    appsecret: xxx
}
router.get('/wxoauth', function (req, res) {
    if (req.query.code) {
        var redirect_uri = new wxoauth.wechatOAuth({app_id: config.appid, redirect_url: xxxx}).getRedirectUrl();
        return res.redirect(redirect_uri)
    } else {
        new wxoauth.wechatOAuth({
            app_id: config.appid,
            app_secret: config.appsecret,
            code: req.query.code,
            scope: snsapi_base,
            callback: function (response) { /* do something */}
        }).getAccessToken();
    }
})
