要在Angular中解决CORS中忽略设置Cookie和删除Cookie的头信息问题,可以通过修改请求头信息的方式来实现。以下是一个代码示例:
import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpHandler, HttpRequest, HttpEvent } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable()
export class CookieInterceptor implements HttpInterceptor {
intercept(req: HttpRequest, next: HttpHandler): Observable> {
// 添加Cookie到请求头中
req = req.clone({
withCredentials: true
});
return next.handle(req);
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { AppComponent } from './app.component';
import { CookieInterceptor } from './cookie.interceptor';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
HttpClientModule
],
providers: [
{
provide: HTTP_INTERCEPTORS,
useClass: CookieInterceptor,
multi: true
}
],
bootstrap: [AppComponent]
})
export class AppModule { }
这样,每个HTTP请求都会被拦截器拦截,并在请求头中添加withCredentials: true
,从而告诉服务器需要设置和读取Cookie信息。
请注意,该解决方法需要确保服务器已经配置了合适的CORS策略,允许跨域请求,并且响应头中包含了Access-Control-Allow-Credentials: true
。
