Configure JSSDK

{
  appId: 'your app id',                                // 公众号appId，
  secret: 'your secret',                               // 公众号secret，
  corp: false,                                         // 是否企业号，corp account or not, default false
  nonceStrLength: 16,                                  // 随机字符串长度，最长32位，nonceStr length, default 16
  type: 'none',                                        // 票据和token保存方式：file，本地文件，redis，保存在redis，none，默认值，不保存到文件或者redis，type=none时，会强制修改cache=true
  tokenFilename: __dirname + '/local-token.json',      // access_token存储文件，access_token local file，default:__dirname/local-token.json
  ticketFilename: __dirname + '/local-ticket.json'     // jsapi ticket存储文件，jsapi ticket local file，default:__dirname/local-ticket.json
  redisHost: '127.0.0.1',                              // redis server host ip
  redisPort: 6379,                                     // redis server port
  redisAuth: 'your reids passwrd',                     // redis password
  cache: true                                          // 是否缓存在进程内存，默认true
}

Change Log

• 2018-4-24, 添加票据和token保存到redis
• 2019-8-2, 默认会在保存一份token和ticket在运行内存，内存中token和ticket未过时时，直接使用内存数据
• 2019-8-2, 添加Typescript types 文件
• 2019-8-3, 更新usage
• 2019-8-5, 修复回调bug，修订type参数，默认为none方试，只在进程内存缓存，配置项添加cache参数，添加mocha测试用例

TODO

• 支持多公众号版本
