HttpInterceptor在Angular 9中用于jwt令牌刷新的问题
我正在使用jwt进行身份验证。我在提神方面有困难。可能我认为这是因为我在rxjs观测值和操作符方面缺乏经验。我使用auth.service.ts的这些方法从后端获取刷新令牌HttpInterceptor在Angular 9中用于jwt令牌刷新的问题,angular,rxjs,jwt,angular-httpclient,angular-http-interceptors,Angular,Rxjs,Jwt,Angular Httpclient,Angular Http Interceptors,我正在使用jwt进行身份验证。我在提神方面有困难。可能我认为这是因为我在rxjs观测值和操作符方面缺乏经验。我使用auth.service.ts的这些方法从后端获取刷新令牌 @Injectable() export class AuthInterceptor implements HttpInterceptor { constructor(private authService: AuthService) {} intercept(request: HttpRequest<an

这是我的拦截器auth interceptor.ts
@Injectable()
export class AuthInterceptor implements HttpInterceptor {
constructor(private authService: AuthService) {}

if (this.authService.hasValidToken()) {
request = this.addAuthenticationToken(request);
}
return next.handle(request).pipe(
catchError(error => {
if (error instanceof HttpErrorResponse && error.status === 401) {
return this.handle401Error(request, next);
} else {
throw error;
}
}));
}
handle401Error(request: HttpRequest<any>, next: HttpHandler) {
return this.authService.getNewAccessToken().pipe(
switchMap((response: Token) => {
return next.handle(this.addAuthenticationToken(request));
})
)
}
addAuthenticationToken(request: HttpRequest<any>) {
const authToken = this.authService.getAuthToken();
return request.clone({
setHeaders: {
'Authorization': `Bearer ${authToken}`
}
});
}
}

我的ide显示以下错误
Property 'intercept' in type 'AuthInterceptor' is not assignable to the same property in base type 'HttpInterceptor'.
Type '(request: HttpRequest<any>, next: HttpHandler) => Observable<unknown>' is not assignable to type '(req: HttpRequest<any>, next: HttpHandler) => Observable<HttpEvent<any>>'.
Type 'Observable<unknown>' is not assignable to type 'Observable<HttpEvent<any>>'.
Type 'unknown' is not assignable to type 'HttpEvent<any>'.
Property 'type' is missing in type '{}' but required in type 'HttpUserEvent<any>'.
类型“AuthInterceptor”中的属性“intercept”不能分配给基类型“HttpInterceptor”中的相同属性。
类型'(请求:HttpRequest,下一个:HttpHandler)=>Observable'不可分配给类型'(请求:HttpRequest,下一个:HttpHandler)=>Observable'。
类型“Observable”不可分配给类型“Observable”。
类型“未知”不可分配给类型“HttpEvent”。
类型“{}”中缺少属性“type”,但类型“HttpUserEvent”中需要属性“type”。
而且
Argument of type '(error: any) => void | Observable<never>' is not assignable to parameter of type '(err: any, caught: Observable<HttpEvent<any>>) => ObservableInput<any>'.
Type 'void | Observable<never>' is not assignable to type 'ObservableInput<any>'.
Type 'void' is not assignable to type 'ObservableInput<any>'.
类型为“(error:any)=>void | Observable”的参数不能分配给类型为“(err:any,capture:Observable)=>ObservableInput”的参数。
类型“void | Observable”不可分配给类型“ObservableInput”。
类型“void”不可分配给类型“ObservableInput”。
我想我可能弄错了返回类型,但我不知道出了什么问题,我终于找到了解决办法。不管怎样,也许有人可以尝试改进它 我做了以下更改,现在它可以工作了 将Observable>添加到截取签名会导致我问题中解释的第一个问题消失。对于第二个问题,我遵循问题评论中的建议。 拦截器类

而我的身份验证服务中获取刷新令牌的功能已修改为
getNewAccessToken(){
return this.httpClient.post<Token>(`${this.baseService.baseUrl}auth-token-refresh/`, { refresh: this.getRefreshToken() }, this.baseService.httpOptions).pipe(
tap((response:Token) => {
this.cookieService.set(environment.tokenAccessName, response.access, null, '/', null, null, 'Strict');
}
));
}
getNewAccessToken(){
返回此.httpClient.post(`${this.baseService.baseUrl}auth-token-refresh/`,{refresh:this.getrefreshttoken()},this.baseService.httpOptions)。管道(
点击((响应:令牌)=>{
this.cookieService.set(environment.tokenAccessName,response.access,null,“/”,null,null,'Strict');
}
));
}
我们可以获得您的身份验证拦截器的内容吗?@htn谢谢,我没有注意到我粘贴了错误的代码。我理解您的意图。很容易找到错误:handle401Error应该返回一个可观察的(此处无效)。第一个返回投掷错误应替换为投掷错误代码>。对于第二个,不要在subscribe的errorHandler中返回任何内容。然而,要给你一个正确的答案并不容易
