HarmonyOS HTTP请求返回的cookie是一个字符串类型，怎么取值

由于很多系统已解析了http模块的cookie，http模块cookie的格式目前不会调整，开发者可以尝试用如下的方法解析cookie

export function parseCookie(str:string):ResponseCookie[]{
  if(str.length == 0){
    return [];
  }
  let cookies = str.split("\r\n");
  let res:ResponseCookie[] = [];
  for(let item of cookies){
    let citem = item.split("\t");
    let key = citem[5];
    let val = citem.length ==7?citem[6]:"";
    let coo = new ResponseCookie(key,val)
    res.push(coo)
  }
  return res;
}

export class ResponseCookie{
  private name:string;

  private value?:string;

  constructor(name:string,value:string|undefined) {
    this.name = name;
    this.value =value;
  }

  public getName():string{
    return this.name;
  }

  public setName(name:string){
    this.name = name;
  }

  public getValue():string|undefined{
    return this.value;
  }

  public setValue(value:string|undefined){
    this.value = value;
  }
}
