角度全局错误处理-指定发生错误的模块

Question

我有一个Angular应用程序，用于容纳多个子应用程序。在这个应用程序中，我实现了一个GlobalErrorHandlerService，它覆盖了Angular的默认ErrorHandler：

global-error-handler.service.ts

import { Injectable, ErrorHandler, Injector } from '@angular/core';
import {ErrorLogger} from '../services/error-logger.service';
import { HttpErrorResponse } from '@angular/common/http';

// Global error handler for logging errors
@Injectable()
export class GlobalErrorHandlerService extends ErrorHandler {
    constructor(private injector : Injector, private errorLoggerService: ErrorLoggerService) {


        super();
    }

    handleError(error: any) {
      let loggerService = this.injector.get(ErrorLoggerService);
      loggerService.logError(error)    
      .subscribe(
        data => console.warn(data),
        error => {throw error},
        () => console.log("empty")
      );

  }
}

这会自动捕获所有错误并将其发送到全局ErrorLoggerService，以将这些错误记录到数据库中：

error-logger.service.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpResponse, HttpRequest, HttpHeaders, HttpInterceptor, HttpHandler, HttpEvent, HttpParams, HttpErrorResponse} from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { from } from 'rxjs';
import { map, filter, catchError, mergeMap } from 'rxjs/operators';
import { AppConstants } from '../app-constants/app-constants';


@Injectable({
  providedIn: 'root'
})
export class ErrorLoggerService {

  constructor(private http: HttpClient) { };

  logError(error: any):Observable<any> {

    const date = new Date().toUTCString();

    const httpOptions = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json'
      }),
      withCredentials: true
    };

    //******** log errors based on type ********//
    if (error instanceof HttpErrorResponse) {

      //** POST error to db **//
      return this.http.post('http://path-to-my-api-model-which-logs-to-db',
      { Date: date, type: error.type, message: error.message, stackTrace: "testStackTraceSERVICE", lineNumber: "testLineNumber", code: "testCode" },
      httpOptions)

    }
    else if (error instanceof TypeError) {

      //** POST error to db **//
      return this.http.post('http://path-to-my-api-model-which-logs-to-db',
      { Date: date, type: error.name, message: error.message, stackTrace: error.stack, lineNumber: "TypeError lineNumber", code: "testCode" },
      httpOptions)
    }
    else if (error instanceof Error) {
      console.error(date, AppConstants.generalError, error.message, error.stack);
    }
    else if(error instanceof ErrorEvent){
      //A client-side or network error occurred. Handle it accordingly.
      console.error(date, AppConstants.generalError, error.message, error.filename);
    }
    else {
      console.error(date, AppConstants.somethingHappened, error.message, error.stack);
    }
  }
}

这将正确记录到数据库。但是，在此数据库表中记录了我们的错误，我想创建一个Application列，并希望用发生错误的子应用程序的名称填充。

我该如何完成？有没有办法拉出发生错误的模块，或者类似的方法？这样，我可以将ErrorLoggerService条件包装在较大的if语句中，该语句的内容如下：

if (error is from Application A) {
    var appName = Application A; 
    //log errors to db
} else if (error is from Application B) {
    var appName = Application A:
    //log errors to db
}
