[英]error handler is getting called twice angular http_interceptor
in my angular application I have a global error handler which handles all the error.在我的 angular 应用程序中,我有一个全局错误处理程序来处理所有错误。 also, I have http interceptor where I am trying to log the error when it happens.另外,我有 http 拦截器,我试图在错误发生时记录错误。 but, the http interceptor requires to return the observable when it catches error, right now I am throwing the error so internally its triggering the global error handler makes the error handler getting called twice.但是,http 拦截器需要在捕获错误时返回可观察对象,现在我正在抛出错误,因此在内部触发全局错误处理程序会使错误处理程序被调用两次。 I can remove the error handler from the http interceptor and let the global error handler does the job but I will not get the correlation ID of the request to stitch the entire requests.我可以从 http 拦截器中删除错误处理程序,让全局错误处理程序完成这项工作,但我不会获得请求的相关 ID 来拼接整个请求。 I am having two questions, when an error happens is there a way we can access request headers (so that I can get the correleation ID) or instead or throwing the error again is there anything else I can do?我有两个问题,当发生错误时,我们是否可以访问请求标头(以便我可以获取关联 ID),或者再次抛出错误,我还能做些什么吗?
here is the current interceptor.这是当前的拦截器。
catchError((error: HttpErrorResponse) => {
this.logger.logError(
error
nextReq.headers.get('x-correlation-id') ?? ''
);
return throwError(error);
I have added a check in the global error handler, that will only call the logger when its not an instance of HTTPError.我在全局错误处理程序中添加了一个检查,它只会在它不是 HTTPError 实例时调用记录器。
if (error instanceof HttpErrorResponse) {
// HTTP errors will be handled in interceptor itself.
} else {
this.logger.logException(error);
}
