HarmonyOS鸿蒙Next中axios请求

HarmonyOS鸿蒙Next中axios请求 我这边在请求拦截器里打印request里data里面的内容是有值

但是request打印出来data却为空

demo如下：

postMethod() {

  let postUrl: string = 'http://***.***:8848/checkParams';

  let simpleForm: rcp.FormFields = {};

  simpleForm['txnBody'] = "XXX";

  simpleForm['txnHeaderInfo'] = "xxx"

  let rcpSession: rcp.Session = rcp.createSession();

  let result = rcpSession.post(postUrl, simpleForm)

  result.then((res) => {

    console.log('res： ' + JSON.stringify(res))

    if (res.body) {

      let re = this.ArrayBuffer2String(res.body)

      console.log('re： ' + re)

    }
  }).catch((err: BusinessError) => {

    console.error(`err: err code is ${err.code}, err message is ${err.message}`);

  });
 }

 ArrayBuffer2String(buf: ArrayBuffer) {

  const decoder = util.TextDecoder.create("utf-8");

  const str = decoder.decodeWithStream(new Uint8Array(buf));

  return str;
}

simpleForm支持动态增减入参对象。请求到后台后，Java侧可以使用IOUtils.toString(request.getReader())解析出响应参数

在HarmonyOS鸿蒙Next中，axios请求可以通过使用@ohos.net.http模块来实现。@ohos.net.http是鸿蒙系统提供的网络请求库，支持HTTP和HTTPS协议的请求。以下是使用@ohos.net.http进行GET请求的示例代码：

import http from '@ohos.net.http';

// 创建http请求对象
let httpRequest = http.createHttp();

// 发起GET请求
httpRequest.request(
  "https://api.example.com/data", 
  {
    method: http.RequestMethod.GET,
    header: {
      'Content-Type': 'application/json'
    }
  }, (err, data) => {
    if (err) {
      console.error(`Request failed, code is ${err.code}, message is ${err.message}`);
    } else {
      console.info(`Request success, data is ${data.result}`);
    }
  }
);

在上述代码中，http.createHttp()用于创建一个HTTP请求对象，httpRequest.request()用于发起请求。请求方法可以通过method参数指定，本例中使用了http.RequestMethod.GET。请求头可以通过header参数设置，返回结果在回调函数中处理。

对于POST请求，只需将method参数改为http.RequestMethod.POST，并在extraData参数中传递请求体数据。

在HarmonyOS鸿蒙Next中，使用axios进行网络请求时，首先需确保已安装axios库。创建请求时，可使用axios.get、axios.post等方法，并传入URL和配置参数。处理响应时，通过.then获取数据，.catch捕获错误。注意，鸿蒙系统对网络权限有严格要求，需在config.json中配置相应权限。以下是示例代码：

import axios from 'axios';

axios.get('https://api.example.com/data')
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error('Error:', error);
  });

确保网络权限配置正确，以保证请求成功执行。
