HarmonyOS 鸿蒙Next rcp get请求传参编码问题

你好，在环境上已经验证过，request.url.search = paramsObject.toString()不会对歧义字符转义两次，只是在toString时会转义，如“+”会被转义为“%2B”，赋值给request.url.search后，request.url.search使用log打印时也是为“%2B”，如果将paramsObject.toString()的字符串使用decodeURIComponent解码，则request.url.search变为“+”，具体代码如下，运行结果见注释：

import { url, util } from '@kit.ArkTS';
import { request } from '@kit.BasicServicesKit';
import { rcp } from '@kit.RemoteCommunicationKit';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    RelativeContainer() {
      Row(){
        Image('media/Photo/17/IMG_1735268301_016/001.webp')
      }.onClick(() =>{
        let urlObject = url.URL.parseURL('https://developer.exampleUrl/?fod=1&bard=2');
        console.log('urlObject slice 1 ' + urlObject.search.slice(1));   //结果为：fod=1&bard=2
        let params = new url.URLParams(urlObject.search.slice(1));
        params.set('baz', '3+'); // Add a third parameter.
        let headers: rcp.RequestHeaders = {
          "accept": "application/json"
        };
        let content = "data to send";
        let configuration: rcp.Configuration = {
          transfer: {
            timeout: { connectMs: 60000, transferMs: 60000 }
          }
        };
        let cookies: rcp.RequestCookies = { 'name1': 'value1', 'name2': 'value2' };
        let transferRange: rcp.TransferRange = { from: 100, to: 200 };
        let req = new rcp.Request("http://example.com", "POST", headers, content, cookies, transferRange, configuration);
        console.log('params.toString() ' + params.toString());   //结果为：fod=1&bard=2&baz=3%2B
        req.url.search = params.toString();
        console.log('req.url.search' + req.url.search);          //结果为：?fod=1&bard=2&baz=3%2B
        req.url.search = decodeURIComponent(params.toString());
        console.log('req.url.search decodeURIComponent' + req.url.search);//结果为：?fod=1&bard=2&baz=3+
      })
    }
    .height('100%')
    .width('100%')
  }
