鸿蒙~与服务端网络通信(二) ： 第三方网络请求库 Axios

• axios 是一个基于promise的网络请求库
• 安装 三方工具 axios

 ohpm install @ohos/axios

• 移动端：demo： 需要自己二次封装

import axios, { AxiosResponse, FormData } from '@ohos/axios'

const TAG = "huxiubo"
@Entry
@Component
struct Index {
  @State user:gData = null
  @State pData: pData = null;

 // get 请求
  getUserinfo() {
    console.info(TAG, `getUerinfo`);
    axios.get("http://192.168.0.113:8080/userinfo")
      .then((res: AxiosResponse<gData>) => {
        console.info(TAG, `Successed  ${JSON.stringify(res.data)}`);
        this.user = res.data
      })
      .catch((err: Error) => {
        console.error(TAG,  `error: ${JSON.stringify(err)}`)
      })
  }

 // post请求
  postData() {
    let form = new FormData()
    form.append('firstName', 'hu')
    form.append('lastName', 'xiubo')

    console.info(TAG, `${JSON.stringify(form)}`);

    axios.post("http://192.168.0.113:8080/addName", form)
      .then((res: AxiosResponse) => {
        console.info(TAG, `Successed  ${JSON.stringify(res.data)}`);
        this.pData = res.data
        console.info(TAG, `Successed  ${this.pData.fName}`);

      })
      .catch((err: Error) => {
        console.error(TAG,  `error: ${JSON.stringify(err)}`)
      })

  }

  build() {
    Column({space:15}) {
      Text(`get请求结果: ${this.user ? this.user.name :""}`)
      Text(`post请求结果 ${this.pData ? this.pData.fName: ""}`)
      Button("get")
        .onClick(()=> {
          this.getUserinfo()
        })

      Button("post")
        .onClick(()=> {
          this.postData()
        })
    }
    .width('100%')
    .height('100%')
  }
}

interface user {
  firstName:string,
  lastName: string
}

class gData {
  name: string;
  data: string;
}

class pData {
  fName: string;
  lName: string;
}

• server端 ，采用go ,gin

package main

import (
    "fmt"
    "github.com/gin-gonic/gin"
)

func main() {
    server := gin.Default()
    //get 请求
    server.GET("/userinfo", func(ctx *gin.Context) {
        ctx.JSON(200, gin.H{
            "name": "hongmeng",
            "data": "2023-10-11",
        })
    })
       // post
    server.POST("/addName", func(ctx *gin.Context) {
        firstName := ctx.PostForm("firstName")
        lastName := ctx.PostForm("lastName")
        ctx.JSON(200, gin.H{
            "fName": firstName + "  server",
            "lName": lastName + "  server",
        })

        fmt.Printf(" %s ", firstName)

    })

    server.Run()

}
