ich eine Klasse gemacht zu verlängern versuchen, die die Exception in Angular 2. ich das Bootstrap erweitert:Kein Anbieter Ausnahme, wenn die Winkel 2 Exception Klasse
bootstrap(App, [
APP_ROUTER_PROVIDERS,
HTTP_PROVIDERS,
provide(ExceptionHandler, { useClass: CustomExceptionHandler }),
Das funktioniert gut, ergeben sich die Probleme, wenn ich versuche zu injizieren mein API-Dienst. Ich versuchte dies:
@Injectable()
export class CustomExceptionHandler extends ExceptionHandler {
constructor(_exceptionApiService: ExceptionApiService) {
super(new ArrayLogger(_exceptionApiService), true);
}
call(error, stackTrace = null, reason = null) {
super.call(error, stackTrace, reason);
}
}
Dann meine ArrayLogger Klasse:
export class ArrayLogger {
private _exceptionApiService: ExceptionApiService;
constructor(_exceptionApiService: ExceptionApiService) {
this._exceptionApiService = _exceptionApiService;
}
res = [];
log(s: any): void { this.res.push(s); }
logError(s: any): void { this.res.push(s); }
logGroup(s: any): void { this.res.push(s); }
logGroupEnd() {
let error: Error;
let message = this.res[0].replace('EXCEPTION: ', '');
let stack = [];
let index = this.findStackTrace(this.res);
if (index === -1) {
stack.push('Could not find stackTrace!');
} else {
this.res[index].split('\n').map(line => stack.push(line.trim()));
}
error = new Error({
url: window.location.href,
error: message,
stack: stack,
browser: this.getBrowser(navigator.userAgent),
userAgent: navigator.userAgent,
platform: navigator.platform,
datetime: ''
});
this._exceptionApiService.post(error);
}
(...)
}
Das gibt mir den Fehler:
zone.min.js:1 Unhandled Promise rejection: (SystemJS) EXCEPTION: Error during instantiation of ApplicationRef_! (ApplicationRef -> ApplicationRef_).
ORIGINAL EXCEPTION: No provider for ExceptionApiService! (ExceptionHandler -> ExceptionApiService)
ORIGINAL STACKTRACE:
Error: DI Exception
at NoProviderError.BaseException [as constructor] (http://localhost:4200/vendor/@angular/core/src/facade/exceptions.js:27:23)
at NoProviderError.AbstractProviderError [as constructor]
Wie kann ich meine exceptionAPIService injizieren richtig?
