gọi HTTP bằng restful nhiều lần để xử lý 1 list data
Em chào anh, em làm chức năng là gửi notification cho user, ví dụ có 1 event thì phía server phải gửi 1 loạt HTTP restful tới từng client riêng biệt, có cách nào để gửi cả cụm được k ạ

Hơi khó hiểu, bởi vì theo kiến trúc Rest thì server sẽ không lưu trạng thái của client, vì vậy thông thường khi có 1 request thì server sẽ có 1 response trả lại luôn. (Timeout cao nhất là 90s, thường là vậy)

Chính vì vậy sẽ không có việc Server chủ động gửi data cho client.

Ví dụ 1 trường hợp Call APi request yêu cầu thực hiện công việc nào đó và kết quả sẽ có trong tương lai (Chạy job jenkins).

Thì với Rest sẽ trả về response với Header có chứa thông tin tới Link của job để chúng ta call kiểm tra trạng thái và thông tin.
