access-token-redis's Introduction

access-token-redis

使用Redis读取和保存access_token

目的

当我们调用某些基于OAuth认证的API时,常常需要使用保存在一定时间范围内有效的access_token信息。 access-token-redis组件为此类功能提供了统一的解决方案,使用Redis保存需要access_token。

安装

npm install access-token-redis

用法

保存和读取微信企业号平台操作时生成的access_token

var API = require('wechat-enterprise-api');

var redis_host = 'localhost';
var redis_prot = 6379;
var appId = 'your appId';
var expire_time = 7000;
var AccessToken = require('access-token-redis'),
    at = new AccessToken(redis_host, redis_port, appId, expire_time);

var wxapi = new API(options.corpId, options.secret, options.agentId,
    function(callback){                     // 获取数据库中保存的access_token
        at.getToken(callback);
    },
    function(token, callback){              // 保存access_token到数据库中
        at.saveToken(token, callback);
    });

API

初始化


var redis_host = 'localhost';           // redis 服务器host
var redis_prot = 6379;                  // redis端口
var appId = 'your appId';               // app id
var expire_time = 7000;                 // Access token 的保存时间(单位:秒),默认7000

var AccessToken = require('access-token-redis'),
    at = new AccessToken(redis_host, redis_port, appId, expire_time);
    

当我们需要使用 access-token-redis时,首先需要初始化。

读取access_token

getToken(callback) 参数: - callback 回调函数 - err - token

保存access_token

saveToken(token, callback) 参数: - token - callback - err - token
