在 Angular 中添加 Xsrf-Token 的问题 6

Question

通过 API 从表单提交中发布数据成功。

但是在将 X-CSRF-TOKEN 添加到 header 并设置 withCredentials: true 之后结果数据未发布到名为 insert.php

的脚本

错误：

Failed to load http://localhost/simple_api/insert.php: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:4200' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

删除 withCredentials: true 结果数据已成功发布。但是看不到 X-CSRF-TOKEN

app.module.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 { }

user.services.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");
?>

安慰 header 的值，Xsrf-Token 未设置。我应该如何设置 Xsrf-Token 值？

更新：

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);
                }
            ); 
  }

app.module.ts

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

imports: [
    ...
    HttpClientModule,
    HttpClientXsrfModule.withOptions({
      cookieName: 'XSRF-TOKEN',
      headerName: 'X-CSRF-TOKEN'
    })
  ],
...

Answer 1

将以下 header 添加到您的 php 代码中

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

此外，为什么要混合使用旧的 HttpModule 和新的 HttpClient 模块？ RequestOptions 和 Headers 在 angular 6

中已弃用

如果您使用HttpClient，内容类型默认设置为json，withCredentials由HttpClientXsrfModule设置。

您的请求可以简化为

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

编辑 HttpClientXsrfModule 在幕后创建的默认拦截器似乎不处理绝对 url....

Answer 2

Server-side，XSRF-TOKEN不是header，而是cookie来设置预先。此 cookie 应从服务器发送到您的 Angular 应用程序所在的页面，即在下面的示例中，模板 'some.template.html.twig' 应加载 Angular 应用程序。

这样 Angular 将添加并发送正确的 X-XSRF-etc。 header 正确。

请注意：生成 cookie 时必须将 HttpOnly 选项设置为 FALSE , 否则 Angular 将看不到它。

例如如果您使用的是 Symfony，则可以在控制器操作中设置 XSRF cookie，如下所示：

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;
  }
}
