import { initDva, initRequest } from 'dva16'
1.初始化model import user from './user' initDva([user]) 2.初始化请求地址 initRequest(requestUrl, (status, data) => { console.log(status, data) })
########## Model ########## model示例:
import { getSetting } from '../services' import { NRemote, RSetState, EGetSetting, EFetchUser, NUser } from './constants'
const delay = (ms = 0) => new Promise(resolve => setTimeout(resolve, ms)) export default { namespace: NRemote, state: { ping: 'pong', user: { name: 'fred' }, setting: null }, effects: { async [EGetSetting]({ payload }, { call, put, select }) { const {user} = select(NRemote) let setting = await call(getSetting, payload) await put(RSetState, { setting }) await put(EFetchUser, 1, NUser) } }, reducers: { [RSetState](state, { payload }) { return { ...state, ...payload } } } }
########## API ##########

modelsArr :
type => Array
explain => model数组
config :
type => Object
explain => 配置项
{
printLog : Boolean, // default => false (打印日志)
useImmer : Boolean // default => true (应用Immer)
}
2.useStore(namespace) //获取model中state的值
namespace :
type => String
explain => model的namespace
例 :
export default () => {
const { count } = useStore(model的namespace)
return (
<>
<p>{count}</p>
</>
)
}
3.reducer(namespace, type, payload)
namespace :
type => String
explain => model的namespace
type :
type => String
explain => reducer名 / 键名
payload ：
type => Any
explain => 传递参数
4.effect(namespace, type, payload)
namespace :
type => String
explain => model的namespace
type :
type => String
explain => reducer名 / 键名
payload ：
type => Any
explain => 传递参数
5.initRequest(serverHome, errorHanlder)
serverHome :
type => String
explain => model的namespace
errorHanlder :
type => Function
explain => 错误回调函数
6.bindJWTToken(token)
token :
type => String
