配置

配置

ThinkJS 提供了灵活的配置,可以在不同模式下使用不同的配置,且这些配置在服务启动时就已经生效,后续逻辑处理中可以直接使用这些配置。

注意:不可将一个 http 请求中的私有值设置到配置中,这将会被下一个 http 设置的值给冲掉。

项目环境

ThinkJS 默认支持 3 种项目环境,可以根据不同的环境进行配置,以满足不同情况下的配置需要。

  • development 开发环境
  • testing 测试环境
  • production 线上环境

项目里也可以扩展其他的环境,当前使用哪种环境可以在 入口文件 中设置,设置 env 值即可。

定义配置文件

项目里可以设置公共配置文件和模块下的配置文件:

  • 公共配置目录 src/common/config
  • 模块配置目录 src/[module]/config

config/config.js

存放一些基本的配置,如:

export default {
  port: 8360, 
  host: "",
  encoding: "utf-8",
  ...
}

config/[name].js

存放具体功能的配置文件,如:db.js 为数据库配置,redis 为 redis 配置。

// db.js
export default {
  type: "mysql",
  host: "127.0.0.1",
  port: "",
  name: "",
  user: "",
  ...
};

config/env/[mode].js

项目模式的配置,如:env/development.jsenv/testing.jsenv/production.js

//env/development.js
export default {
  db: { //开发模式下数据库配置
    type: "mysql",
    host: "127.0.0.1",
    port: "",
    ...
  }
}

config/locale/[lang].js

国际化语言包配置,如: locale/en.jslocale/zh-CN.js


配置格式采用 key: value 的形式,并且 key 不区分大小写。

加载配置文件

框架支持多种级别的配置文件,会按以下顺序进行读取:

框架默认的配置 -> 项目模式下框架配置 -> 项目公共配置 -> 项目模式下的公共配置 -> 模块下的配置

配置读取

通过 config 方法获取

在 Controller,Logic,Middleware 等地方可以通过 this.config 来获取。如:

let db = this.config("db"); //读取数据库的所有配置
let host = this.config("db.host"); //读取数据库的 host 配置,等同于 db.host

通过 http 对象上的 config 方法获取

http 对象也有 config 方法用来获取相关的配置,如:

let db = http.config("db");

其他地方配置读取

其他地方可以通过 think.config 来读取相关的配置:

let db = think.config("db"); //读取通用模块下的数据库配置
let db1 = think.config("db", undefined, "home"); //获取 home 模块下数据库配置

注: 路由解析前,无法通过 config 方法或者 http 对象上的 config 方法来获取非通用模块下的配置,所以路由解析前就使用的配置需要定义在通用模块里。

系统默认配置

env

项目模式下的配置,config/env/development.js

export default {
  auto_reload: true,
  log_request: true,
  gc: {
    on: false
  },
  error: {
    detail: true
  }
}

config/env/testing.js 和 config/env/produciton.js 无默认配置。

locale

国际化语言包配置,默认的配置如下:

// config/locale/en.js
export default {
  CONTROLLER_NOT_FOUND: "controller `%s` not found. url is `%s`.",
  CONTROLLER_INVALID: "controller `%s` is not valid. url is `%s`",

扩展配置

项目里可以根据需要扩展配置,扩展配置只需在 src/common/config/ 建立对应的文件即可,如:

// src/common/config/foo.js
export default {
  name: "bar"
}

这样就可以通过 think.config('foo') 来获取对应的配置了。
