Question

我已经使用Lumen构建了一个Rest API接口，应该使用Angular HTTP Requests进行寻址。

现在的问题是，如果我用PUT寻址路由/api/blog，我会得到一个不允许来自Lumen的405方法。我已经为CORS编写了一个middlware，它也允许包括PUT在内的方法。我还使用JWT进行客户端身份验证。

我需要你的帮助。

BlogInformationService：

import {Injectable} from '@angular/core';
import {HttpClient, HttpHeaders} from '@angular/common/http';
import {environment} from '../../environments/environment';
import {BlogInformation} from '../models/BlogInformation';

@Injectable()
export class BlogInformationService {
  private endPoint = environment.apiUrl + '/api/blog';

  constructor(private http: HttpClient) {
  }

  getAll() {
    return this.http.get<BlogInformation[]>(this.endPoint);
  }

  getByHash(hash: string) {
    return this.http.get<BlogInformation>(this.endPoint + '/' + hash);
  }

  create(blogInformation: BlogInformation) {
    return this.http.post(this.endPoint + '/add', blogInformation);
  }

  update(blogInformation: BlogInformation) {
    const httpOptions = {
      headers: new HttpHeaders({
        'Authorization': localStorage.getItem('access_token')
      })
    };
    return this.http.put(this.endPoint, blogInformation, httpOptions);
  }

  delete(blogInformation: BlogInformation) {

  }
}

流明路由：

$router->group([
    "middleware" => [
        "authMiddleware",
        "secureBlogMiddleware"
    ]
], function ($router) {
    $router->post('/api/blog/add', ["uses" => "BlogController@addBlog"]);
    Route::put("/api/blog", "BlogController@editBlog");
});

Cors Middleware：

<?php

namespace App\Http\Middleware;


class CorsMiddleware
{
    public function handle($request, \Closure $next)
    {
        $response = $next($request);
        $response->header('Access-Control-Allow-Headers', $request->header('Access-Control-Request-Headers'));
        $response->header('Access-Control-Allow-Method', 'POST, GET, OPTIONS, PUT, DELETE');
        $response->header('Access-Control-Allow-Origin', '*');
        return $response;
    }
}

中间件配置：

/*
|--------------------------------------------------------------------------
| Register Middleware
|--------------------------------------------------------------------------
|
| Next, we will register the middleware with the application. These can
| be global middleware that run before and after each request into a
| route or middleware that'll be assigned to some specific routes.
|
*/

$app->middleware([
    App\Http\Middleware\CorsMiddleware::class
]);

请求标题：

Answer 1

尝试更改

Route::put("/api/blog", "BlogController@editBlog");

的

$router->put("/api/blog", "BlogController@editBlog");

Answer 2

Lumen喜欢Laravel作弊与PUT / PATCH等请求。这些需要是带有额外POST变量的POST请求＆＃39; _method＆＃39;设置为请求类型（例如）PUT。

Angular和Lumen不想通过PUT请求进行通信
