Get方式

根据JSON内容设置接口

//如果是数组，则用data:Data[] = []
//如果是具体类型，则用dataModule:DataModule = new DataModule
Interface Data{
    data1:CommonType
    data2:sonType
}
class DataModule implements Data{
    data1:CommonType
    data2:specialType
    constructor(info:Data){
      this.data1 = info.data1
      this.data2 = info.data2
    }
}
class specialType{
    constructor(){

    }
}
//初始化
@State dataList:DataModule[] = [
  new DataModule({data1:xx,data2:yy}),
  new DataModule({data1:xx,data2:yy}),
]

获取

import { http } from '@kit.NetworkKit'
let url = 'xxx'
//创建http
let httpRequest = http.createHttp()
//请求
//含method,header
httpRequest.request(url,{
  method:http.RequestMethod.GET,
  header:{
    cookie:'',
    agent:''
  }
}).then((info)=>{
  this.result = JSON.parse(info.result.toString())
})
//Json.stringify()

使用

this.data.xxx?.yyy

申请网络权限

src/main/resources/module.json5中的module添加"requestPermissions": [{“name”: “ohos.permission.INTERNET”
}],

模板

import { http } from '@kit.NetworkKit'
import { promptAction } from '@kit.ArkUI'
import { BaseRespData } from '../models/BaseRespData'

//泛型，让调用者决定是什么类型
export async function requestHttp<T>(url:string,method:http.RequestMethod=http.RequestMethod.GET,data?:object):Promise<T>{
  let httpRequest = http.createHttp()
  let options:http.HttpRequestOptions={
    header:{},
    method:method,
    extraData:data,
    readTimeout:10*1000,
    connectTimeout:10*1000
  }
  let httpResult = await httpRequest.request(url,options)
  console.log('???:'+httpResult.result.toString())
  try {
    if (httpResult.responseCode === 401) {
      promptAction.showToast({message:"Token已过期"})
      return Promise.reject((new Error(JSON.stringify(httpResult))))
    } else if(httpResult.responseCode === 404){
      promptAction.showToast(({message:"请求地址错误"}))
      return Promise.reject(new Error(JSON.stringify(httpResult)))
    }else {
      let result = JSON.parse(httpResult.result.toString()) as BaseRespData<T>
      if(result.code === 200){
        return result.data
      } else{
        promptAction.showToast({message:"业务执行失败"+result.msg})
        return Promise.reject(new Error("业务执行失败")+result.msg)
      }
    }
  }catch (err) {
    console.error("网络请求错误"+JSON.stringify(err))
    return Promise.reject(new Error("网络请求错误"+JSON.stringify(err)))
  } finally {
    httpRequest.destroy()
  }
}
