HarmonyOS ArkTS上怎么做网络并行化请求？

Answer 1

HarmonyOS支持并发请求，建议使用rcp：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/remote-communication-rcp-V5\#section18613443123412

参考使用代码：

sendRequest() {
  const session = rcp.createSession();
  let req = new rcp.Request("xxx", "POST");
  let req1 = new rcp.Request("xxx", "POST");
  let req2 = new rcp.Request("xxx", "POST");

  session.fetch(req).then((response) => {
    console.info(`${response}` + '第一个请求');
  }).catch((err: BusinessError) => {
    console.error(`err: err code is ${err.code}, err message is ${err.message}`);
  });

  session.fetch(req1).then((response) => {
    console.info(`${response}` + '第二个请求');
  }).catch((err: BusinessError) => {
    console.error(`err1: err code is ${err.code}, err message is ${err.message}`);
  });

  session.fetch(req2).then((response) => {
    console.info(`${response}` + '第三个请求');
  }).catch((err: BusinessError) => {
    console.error(`err2: err code is ${err.code}, err message is ${err.message}`);
  });
}
