Question

我遇到与this问题完全相同的问题，但对于Angular 2。

总之，当向另一个域发送HTTP请求时，即使正确设置了CORS头，也不会发送JSESSIONID cookie。 Angular 1.x解决方案是设置以下配置：

.config(function ($routeProvider, $httpProvider) {
    $httpProvider.defaults.withCredentials = true;
    //rest of route code

但是我无法找到Angular 2的替代解决方案。

有什么想法吗？谢谢！

您需要扩展默认的Http服务并将withCredentials设置为true

http.service.ts

import { Injectable } from '@angular/core';
import { Headers, Http, Request, RequestOptions, Response, XHRBackend } from '@angular/http';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class HttpService extends Http {
  constructor(backend: XHRBackend, options: RequestOptions) {
    super(backend, options);
  }

  request(url: string | Request, options?: any): Observable<Response> {
    if (typeof url === 'string') {
        if (!options) {
            options = {headers: new Headers()};
        }
        options.withCredentials = true;
    } else {
        url.withCredentials = true;
    }

    return super.request(url, options);
  }
}

http.service.factory.ts

import { RequestOptions, XHRBackend } from '@angular/http';
import { HttpService } from './http.service';

export function HttpServiceFactory(backend: XHRBackend, defaultOptions: RequestOptions) {
  return new HttpService(backend, defaultOptions);
};

并在您的模块文件中，您需要替换您的http服务

import { HttpServiceFactory } from './http.service.factory';
import { Http, RequestOptions, XHRBackend } from '@angular/http';

...

providers: [
  {
    provide: Http,
    useFactory: HttpServiceFactory,
    deps: [XHRBackend, RequestOptions]
  }
]

Answer 2

当您从'@ angular / http'导入{Http，Response，Headers}使用Http服务时，您可以设置withCredentials：true;

post(params:string, obj:any): Observable<any> {
    let headers = new Headers();
    headers.append("content-type", "application/json"); 
    return this.http.post(this.apiUrl + params, JSON.stringify(obj), { headers: headers, withCredentials: true })
        .map((response : Response)=>{
                return response.json();
            });;           
}

Angular2替换$ httpProvider.defaults.withCredentials
