连接时间过长时重试连接 [英] Retry connection when it takes too long

问题描述

当呼叫在挂起时停留超过几秒钟时，Angular 是否可以重试连接?

Is it possible in Angular to retry a connection when the calls stays for more then a couple of seconds on pending?

推荐答案

应该可以结合 pipe、timeout 和 retry来自 Rxjs.如果超过timeout，retry 4次，否则，catchError.

Should be doable with a combination of pipe, timeout and retry from Rxjs. If timeout is exceeded, retry 4 times, else, catchError.

return this.httpClient.post(url, data, httpOptions).pipe(
  timeout(3000),
  retry(4),
  catchError(<DO SOMETHING>)
);
