我知道,这个问题听起来很重复,我已经尝试了所有在stackover流上发现的问题,但无法解决此问题,请耐心等待
为了使您能够重现错误,我向您提供了整个代码,

问题
我收到以下错误:
有关方案的信息(注释)
注意1
文件:response-interceptor.service.ts
路径:./src/app/shared/interceptors/response-interceptor/
我正在拦截HTTPClient
响应以检查401
错误,当错误出现时,我需要让用户重新登录。
为了向用户显示重新登录提示,我制作了一个带有功能“relogin”的global-functions-services
注意2
文件:global-function.service.ts
路径:./src/app/shared/services/helper-services/global-function/
这是所有一切开始发生的地方...
我一注入(inject)PersonService
constructor(
public dialog: MatDialog,
private _personService: PersonService
) { }
我收到此错误,在PersonService中找不到任何可能导致此问题的
import
。PersonService :
./src/app/shared/services/api-services/person/person.service.ts
import { IRequest } from './../../../interfaces/I-request';
import { environment } from 'environments/environment';
import { Injectable } from '@angular/core';
// for service
import 'rxjs/add/operator/map'
import 'rxjs/add/operator/toPromise';
// models
import { Person } from 'app/shared/models/person';
import { RequestFactoryService, REQUEST_TYPES } from 'app/shared/factories/request-factory/request-factory.service';
@Injectable()
export class PersonService {
private _requestService: IRequest;
constructor(
_requestFactoryService: RequestFactoryService
) {
this._requestService = _requestFactoryService.getStorage(REQUEST_TYPES.HTTP);
}
public signup(record): Promise<Person> {
let url = environment.api + 'person/public/signup';
return this._requestService.post(url, record) as Promise<Person>;;
}
public authenticate(code: string, password: string): Promise<Person> {
let url = environment.api + 'auth/signin';
let postData = {
code: code,
password: password
}
return this._requestService.post(url, postData) as Promise<Person>;
}

请为此提出一个解决方案,我已经浪费了两天时间来解决问题,但是没有运气。
非常感谢!!提前
最佳答案
循环依赖,意味着无休止地盘旋,就像行星绕太阳公转。
解决方案:打破依赖关系链,重构代码。
您具有 GlobalFunctionService -> PersonService->等等...-> ResponseInterceptorService->并返回-> GlobalFunctionService 。
循环完成。
从GlobalFunctionService中删除PersonService依赖项。 (无论如何,如果您需要它,请不要使用它,然后找到另一种解决方法。)
import { PersonService } from 'app/shared/services/api-services/person/person.service';
import { Injectable } from '@angular/core';
import { InputModalComponent } from 'app/shared/components/input-modal/input-modal.component';
import { MatDialog } from '@angular/material';
@Injectable()
export class GlobalFunctionService {
constructor(
public dialog: MatDialog
) { }
relogin(): void {
let dialogRef = this.dialog.open(InputModalComponent, {
width: '250px',
data: { title: "Please provide your password to re-login." }
});
dialogRef.afterClosed().subscribe(result => {
debugger
console.log('The dialog was closed');
let password = result;
});
}
}
