在Angular 10应用程序中,如果跨源请求不发送JWT刷新令牌,可以通过设置Angular的HTTP拦截器来解决此问题。以下是一个示例:
auth.interceptor.ts
的文件,并在其中编写以下代码:import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable()
export class AuthInterceptor implements HttpInterceptor {
intercept(request: HttpRequest, next: HttpHandler): Observable> {
// 获取存储在本地的JWT刷新令牌
const refreshToken = localStorage.getItem('refreshToken');
// 如果请求是跨源请求,则添加Authorization header并发送JWT刷新令牌
if (request.withCredentials) {
request = request.clone({
setHeaders: {
Authorization: `Bearer ${refreshToken}`
}
});
}
return next.handle(request);
}
}
app.module.ts
文件中,将AuthInterceptor
添加到提供的HTTP_INTERCEPTORS
令牌中。如果还没有HTTP_INTERCEPTORS
,则需要导入它。import { NgModule } from '@angular/core';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { AuthInterceptor } from './auth.interceptor';
@NgModule({
imports: [HttpClientModule],
providers: [
{
provide: HTTP_INTERCEPTORS,
useClass: AuthInterceptor,
multi: true
}
]
})
export class AppModule { }
withCredentials
属性。import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
@Injectable()
export class ApiService {
constructor(private http: HttpClient) { }
getSomeData() {
return this.http.get('https://example.com/api/somedata', { withCredentials: true });
}
}
在以上代码中,withCredentials
属性设置为true
,表示发送跨源请求,并且会在请求中包含相应的JWT刷新令牌。
请确保在服务器端配置允许跨源请求,并正确处理JWT刷新令牌。
