微信公共平台OAuth接口消息接口服务中间件与API SDK
OAuth2.0网页授权,使用此接口须通过微信认证,如果用户在微信中(Web微信除外)访问公众号的第三方网页,公众号开发者可以通过此接口获取当前用户基本信息(包括昵称、性别、城市、国家)。详见:官方文档
详细参见API文档
$ npm install wechat-oauth
引入OAuth并实例化
var OAuth = require('wechat-oauth');
var client = new OAuth('your appid', 'your secret');
以上即可满足单进程使用。 当多进程时,token需要全局维护,以下为保存token的接口。
var oauthApi = new OAuth('appid', 'secret', function (openid, callback) {
// 传入一个根据openid获取对应的全局token的方法
// 在getUser时会通过该方法来获取token
fs.readFile(openid +':access_token.txt', 'utf8', function (err, txt) {
if (err) {return callback(err);}
callback(null, JSON.parse(txt));
});
}, function (openid, token, callback) {
// 请将token存储到全局,跨进程、跨机器级别的全局,比如写到数据库、redis等
// 这样才能在cluster模式及多机情况下使用,以下为写入到文件的示例
// 持久化时请注意,每个openid都对应一个唯一的token!
fs.writeFile(openid + ':access_token.txt', JSON.stringify(token), callback);
});
附上全局维护AccessToken的示例代码:
Mongodb|mongoose
var TokenSchema = new Schema({
access_token: String,
expires_in: Number,
refresh_token: String,
openid: String,
scope: String,
create_at: String
});
自定义getToken方法
TokenSchema.statics.getToken = function (openid, cb) {
this.findOne({openid:openid}, function (err, result) {
if (err) throw err;
return cb(null, result);
});
};
自定义saveToken方法
TokenSchema.statics.setToken = function (openid, token, cb) {
// 有则更新,无则添加
var query = {openid: openid};
var options = {upsert: true};
this.update(query, token, options, function (err, result) {
if (err) throw err;
return cb(null);
});
};
mongoose.model('Token', 'TokenSchema');
初始化:
var client = new OAuth(appid, secret, function (openid, callback) {
// 传入一个根据openid获取对应的全局token的方法
// 在getUser时会通过该方法来获取token
Token.getToken(openid, callback);
}, function (openid, token, callback) {
// 持久化时请注意,每个openid都对应一个唯一的token!
Token.setToken(openid, token, callback);
});
MySQL:
建表SQL
CREATE TABLE `token` (
`access_token` varchar(200) COLLATE utf8_bin NOT NULL COMMENT '令牌',
`expires_in` varchar(10) COLLATE utf8_bin NOT NULL COMMENT '有效期',
`refresh_token` varchar(200) COLLATE utf8_bin NOT NULL COMMENT '刷新参数',
`openid` varchar(50) COLLATE utf8_bin NOT NULL COMMENT '用户编号',
`scope` varchar(50) COLLATE utf8_bin NOT NULL COMMENT '作用域',
`create_at` varchar(20) COLLATE utf8_bin NOT NULL COMMENT '令牌建立时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='微信令牌表';
设置openid为唯一索引
ALTER TABLE `token`
ADD UNIQUE KEY `openid` (`openid`);
使用示例:
var client = new Oauth(appid, secret, function (openid, callback) {
var sql = 'SELECT * FROM token WHERE openid = ?';
db.query(sql, [openid], function (err, result) {
if(err) {
return callback(err);
}
return callback(null, result[0]);
});
}, function (openid, token, callback) {
var sql = 'REPLACE INTO token(access_token, expires_in, refresh_token, openid, scope, create_at) VALUES(?, ?, ?, ?, ?, ?)';
var fields = [token.access_token, token.expires_in, token.refresh_token, token.openid, token.scope, token.create_at];
db.query(sql, fields, function (err, result) {
return callback(err);
});
});
使用小程序时,需要在初始化OAuth时指定isMiniProgram
参数为true
单进程
var OAuth = require('wechat-oauth');
var client = new OAuth('your appid', 'your secret', null, null, true); // 最后一个参数即isMiniProgram
多进程
var oauthApi = new OAuth('appid', 'secret', getToken, saveToken, true);
注意:微信不会将用户的sessionKey过期时间告知开发者,该时间会根据用户与小程序互动频繁程度等因素发生变化,建议根据小程序客户端wx.checkSession()
方法检验凭证是否依旧有效,若失效应该再次使用code换取新的sessionKey。故而此例中的getToken
和saveToken
方法过期机制须有不同。
官方文档
生成引导用户点击的URL。
var url = client.getAuthorizeURL('redirectUrl', 'state', 'scope');
如果是PC上的网页,请使用以下方式生成
var url = client.getAuthorizeURLForWebsite('redirectUrl');
用户点击上步生成的URL后会被重定向到上步设置的 redirectUrl
,并且会带有code
参数,我们可以使用这个code
换取access_token
和用户的openid
client.getAccessToken('code', function (err, result) {
var accessToken = result.data.access_token;
var openid = result.data.openid;
});
如果我们生成引导用户点击的URL中scope
参数值为snsapi_userinfo
,接下来我们就可以使用openid
换取用户详细信息(必须在getAccessToken方法执行完成之后)
client.getUser(openid, function (err, result) {
var userInfo = result;
});
