在角度6中添加Xsrf令牌时出现的问题

Question

从通过API提交的表单中发布数据是成功的。

但是，在将X-CSRF-TOKEN添加到头并设置withCredentials:true之后，结果数据没有发布到名为insert的脚本中。php

错误：

加载失败http://localhost/simple_api/insert.php:对飞行前请求的响应未通过访问控制检查：当请求的凭据模式为“包括”时，响应中“访问控制允许来源”标头的值不得为通配符“*”。起源'http://localhost:4200因此，不允许访问。XMLHttpRequest启动的请求的凭据模式由withCredentials属性控制。

用凭据删除：成功发布了true结果数据。但是看不到X-CSRF-TOKEN

应用程序。单元ts

import { HttpModule } from '@angular/http';
import { AppRoutingModule } from './app-routing.module';
import {HttpClientModule, HttpClientXsrfModule} from "@angular/common/http";
import { UsrService } from './usr.service';
import { AppComponent } from './app.component';

@NgModule({
    declarations: [
      AppComponent,
      RegisterComponent,
      LoginComponent
    ],
    imports: [
      BrowserModule,
      FormsModule,
      HttpModule,
      AppRoutingModule,
      HttpClientModule,
      HttpClientXsrfModule.withOptions({
        cookieName: 'XSRF-TOKEN',
        headerName: 'X-CSRF-TOKEN'
      })
    ],
    providers: [UsrService],
    bootstrap: [AppComponent]
  })
  export class AppModule { }

使用者服务。ts

import { Http, Headers, RequestOptions, Response, URLSearchParams } from '@angular/http';
addUser(info){
    console.log(info);
    let headers = new Headers({ 'Content-Type': 'application/json' });
    let options = new RequestOptions({ headers: headers, withCredentials: true });
    console.log(options);
    return this._http.post("http://localhost/simple_api/insert.php",info, options)
      .pipe(map(()=>""));
  }

insert.php

<?php
$data = json_decode(file_get_contents("php://input"));
header("Access-Control-Allow-Origin: http://localhost:4200");
header("Access-Control-Allow-Headers: X-CSRF-Token, Origin, X-Requested-With, Content-Type, Accept");
?>

import {HttpClient, HttpClientModule, HttpClientXsrfModule} from "@angular/common/http";

constructor(private _http:HttpClient) { }

  addUser(info){
    console.log(info);
    // let headers = new Headers({ 'Content-Type': 'application/json' });
    // let options = new RequestOptions({ headers: headers, withCredentials: true });
    // console.log(options);
    return this._http.post("http://localhost/simple_api/insert.php",info)
        .subscribe(
                data => {
                    console.log("POST Request is successful ", data);
                },
                error => {
                    console.log("Error", error);
                }
            ); 
  }

Answer 1

服务器端，XSRF-TOKEN不是头，而是要事先设置的cookie。这个cookie应该从服务器发送到Angular应用程序所在的页面，即下面的示例中的模板“some”。样板html。twig'应加载Angular应用程序。

这样可以正确添加和发送正确的X-XSRF-etc标题。

请注意：cookie必须在生成时将HttpOnly选项设置为FALSE，否则Angular将看不到它。

例如，如果您使用Symfony，您可以在控制器操作中设置如下XSRF cookie：

namespace App\Controller;

use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class MyController extends Controller
{
  /**
   * Disclaimer: all contents in Route(...) are example contents
   * @Route("some/route", name="my_route")
   * @param Request $request
   * @return \Symfony\Component\HttpFoundation\Response
   */
  public function someAction(Request $request, CsrfTokenManagerInterface $csrf)
  {
    $response = $this->render('some.template.html.twig');
    if(!$request->cookies->get('XSRF-TOKEN')){
      $xsrfCookie = new Cookie('XSRF-TOKEN',
        'A_Token_ID_of_your_Choice',
        time() + 3600, // expiration time 
        '/', // validity path of the cookie, relative to your server 
        null, // domain
        false, // secure: change it to true if you're on HTTPS
        false // httpOnly: Angular needs this to be false
      ); 
      $response->headers->setCookie($xsrfCookie);
    }

    return $response;
  }
}

Answer 2

将以下标题添加到php代码中

header("Access-Control-Allow-Credentials: true");

另外，为什么要混合使用旧的HttpModule和新的HttpClient模块<代码>请求选项和标题在angular 6中不推荐使用

如果使用HttpClient，则默认情况下内容类型已设置为json，并且HttpClientXsrfModule已设置withCredentials。

您的请求可以简化为

 return this._http.post("http://localhost/simple_api/insert.php",info);

编辑由HttpClientXsrfModule在幕后创建的默认拦截器似乎无法处理绝对URL。。。。
