Angular 5 HttpClient忽略了来自WordPress REST API的Post-Cookie标头

[英]Angular 5 HttpClient ignores Set-Cookie header from wordpress REST api post response

我已经在Google上搜索了很多,但似乎无法找到解决我问题的明确答案。 许多类似的情况/解决方案,但没有一个对我有用。

我的设置如下:

环境 :XAMP,Wordpress 4.9和在Angular 5之上运行的Angular Material Design

后端(REST API服务器) :我有一个可以正常运行的Wordpress设置,可以在以下地址顺利运行: http:// localhost /〜XXXX / wordpress 我打算使用后端,以便通过内置的json REST API接口将数据提供给客户端,为此,我为它设置了一个自定义/测试端点:

add_action('rest_api_init', function () {

    register_rest_route('cookie-test/v1', 'set', [
      'methods' => 'POST',
      'callback' => function () {
          setcookie('cookieKey', $_POST['cookieValue'], time()+60*60*24*30);
          return [
            'responseKey' => 'responseValue',
          ];
      },
    ]);
});

实际上,我要实现的是针对前端的某种基于cookie的身份验证,而不是基于wordpress的身份验证! 这段(伪)代码基本上是一个测试平台,目的是检查Cookie的正确功能/在后端和前端之间的交换。

前端 :(部分)

// auth.service.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/mergeMap';

@Injectable()
export class AuthService
{
    constructor(
        private http: HttpClient
    )
    {
    }

    cookieTest() {
        return this.http.post(
            'http://localhost/~XXXX/wordpress/wp-json/cookie-test/v1/set',
            {cookieValue: 'randomValue'},
            {
                observe: 'response', // Full response instead of the body only
                withCredentials: true, // Send cookies
            }
        );
    }
}

// login.component.ts

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

import { Router } from '@angular/router';
import { AuthService } from '../services/auth.service';

@Component({
    selector   : 'login',
    templateUrl: './login.component.html',
    styleUrls  : ['./login.component.scss'],
})

export class LoginComponent implements OnInit
{
    loginForm: FormGroup;
    loginFormErrors: any;

    constructor(
        private formBuilder: FormBuilder,
        private authService: AuthService,
        private router: Router,
    )
    {
        this.loginFormErrors = {
            email   : {},
            password: {}
        };
    }

    ngOnInit()
    {
        this.loginForm = this.formBuilder.group({
            email   : ['', [Validators.required, Validators.email]],
            password: ['', Validators.required],
        });
    }

    onCookieTest()
    {
        this.authService.cookieTest()
            .subscribe(
                response => {
                    const keys: string[] = response.headers.keys();
                    console.log(keys);
                    console.log(response);
                },
                error => {
                    console.log(error);
                }
            );
    }
}

问题 :前端可以到达wordpress REST API端点,而端点又可以正确响应角度的“ post”请求, 但是 ...但是未在浏览器中设置cookie!

从浏览器的调试器控制台中,我可以看到POST响应中的Set-Cookie标头包含正确的字段,但显然浏览器(或Angular的HttpClient?)完全忽略了它!

谷歌搜索我找不到关于<Wordpress REST API> / Angular5的任何信息。 各种各样的后端(ruby,laravel,java,C#等),但是与Angular5的HttpClient的Wordpress无关。

预先感谢您的任何帮助/提示

您需要在后端指定路径(例如,根路径)

setcookie('cookieKey', $_POST['cookieValue'], time()+60*60*24*30, '/')

如果您在设置cookie时未指定路径,则该路径仅在当前路径( .../wp-json/cookie-test/v1/set )上可用,这意味着cookie不会如果您在该域上尝试其他路径,则在将来的请求中被发送到后端
