[英]Spring Boot - Calling a controller from another controller without using RedirectAttributes
我想做的事:
用戶執行特定操作后,將推送通知發送給管理員。
問題:
如果我使用RedirectAttributes,則需要返回一個字符串值以調用另一個端點,但是我還需要向用戶返回http響應和模型。 所以我想知道是否還有另一種方法可以調用另一個端點,或者使用RedirectAttributes進行調用的正確方法是什么?
@GetMapping("get_admin")
public ResponseEntity<Admin> getAdminById(@RequestHeader("lang") String locale,
@RequestParam("id") Integer id,
RedirectAttributes redirectAttrs) throws EntityNotFoundException {
Admin admin = adminService.getAdminById(id);
if (admin == null) {
return new ResponseEntity(new ResponseAdmin(new LangString().getNoSuchAnAdmin(locale),"0"), HttpStatus.OK);
}
redirectAttrs.addFlashAttribute("locale",locale);
redirectAttrs.addFlashAttribute("opType","0");
redirectAttrs.addFlashAttribute("message","message");
redirectAttrs.addFlashAttribute("type","type");
redirectAttrs.addFlashAttribute("data","data");
return new ResponseEntity(new ResponseAdmin(admin), HttpStatus.OK);
>>> I can't write "return redirect:/push_call;" since return type must be ResponseEntity, not String.
}
@GetMapping("push_call")
public ResponseEntity<String> redirectedPush(Model model){
int opType = (int) model.asMap().get("opType");;
String locale = (String) model.asMap().get("locale");;
String messageStr = (String) model.asMap().get("message");;
String dataStr = (String) model.asMap().get("data");;
String typeStr = (String) model.asMap().get("type");;
JSONObject body = new JSONObject();
body.put("to", "XXXXXX");
HttpEntity<String> request = new HttpEntity<>(body.toString());
CompletableFuture<String> pushNotification = androidPushNotificationsService.send(request);
try {
String firebaseResponse = pushNotification.get();
return new ResponseEntity<>(firebaseResponse, HttpStatus.OK);
} catch (InterruptedException | ExecutionException e) {
e.printStackTrace();
}
return new ResponseEntity<>("Push Notification ERROR!", HttpStatus.BAD_REQUEST);
}
只需return redirectedPush(model)
然后
