您是否可以提供有关如何在angular4 +执行GET和POST时使用Cookie的示例或参考?在angularJS上有记录但在Angular.io上没有。 任何等价于:Angular4 +上的“//code.angularjs.org/X.Y.Z/angular-cookies.js” 提前致谢

如果你正在使用新的Angular 5,他们引入了名为HttpInterceptor
(https://angular.io/guide/http#intercepting-all-requests-or-responses)
你可以做的是创建一个拦截器来获取你的cookie并相应地处理它。
import {Injectable} from '@angular/core';
import {HttpEvent, HttpInterceptor, HttpHandler, HttpRequest} from '@angular/common/http';
function getCookie(name) {
const splitCookie = cookie.split(';');
for (let i = 0; i < splitCookie.length; i++) {
const splitValue = val.split('=');
if (splitValue[0] === name) {
return splitValue[1];
}
}
return '';
}
@Injectable()
export class AuthInterceptor implements HttpInterceptor {
constructor(private auth: AuthService) {}
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
// Get the auth header from the service.
const authHeader = getCookie('auth');
// Clone the request to add the new header.
const authReq = req.clone({headers: req.headers.set('Authorization', authHeader)});
// Pass on the cloned request instead of the original request.
return next.handle(authReq);
}
}
您还可以使用此类库来处理Cookie: https://github.com/salemdar/ngx-cookie

我最后写了如下内容:
public postSomethingToServer(myUrl: string): Observable<any> {
var body = `{"username":"ddd","password":"ddd"}`;
const headers = new Headers();
headers.append('Content-Type', 'application/json');
let options = new RequestOptions({ headers: headers, withCredentials: true });
return this.http.post(myUrl, body, options)
.map((response) => {
return response.json();
})
.catch(this.handleError);
}
要在请求中发送cookie,需要在传递给RequestOptions类的对象中使用(withCredentials:true)。
对于ASP Net Core应用程序,如果客户端和服务器在配置CORS所需的不同服务器上运行
app.UseCors(config =>
config.AllowAnyOrigin()
.AllowCredentials());
