Laravel开发简书es一章问题:access_control_exception

释放双眼,带上耳机,听听看~!

在我的课程中原本使用下面的template的方法来初始化,里面使用了es的一个动态类型推测

$param = [
            'json' => [
                'template' => config('scout.elasticsearch.index'),
                'mappings' => [
                    '_default_' => [
                        'dynamic_templates' => [
                            [
                                'strings' => [
                                    'match_mapping_type' => 'string',
                                    'mapping' => [
                                        'type' => 'text',
                                        'analyzer' => 'ik_smart',
                                        'fields' => [
                                            'keyword' => [
                                                'type' => 'keyword'
                                            ]
                                        ]
                                    ]
                                ]
                            ]
                        ]
                    ]
                ],
            ],
        ];

后来发现,在java1.9下会出现权限问题问题:

  {"error":{"root_cause":[{"type":"access_control_exception","reason":"access denied (/"java.io.FilePermission/" /"/Users/ (truncated...)  

解决的方法:

<?php

namespace App/Console/Commands;

use GuzzleHttp/Client;
use Illuminate/Console/Command;

class ESInit extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'es:init';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'init laravel es for post';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        // 创建template
        $client = new Client();

        $url = config('scout.elasticsearch.hosts')[0] . '/_template/tmp';

        try {
            $client->delete($url);
        } catch (/Exception $e) {
            $this->info("===delete模版出现错误==" . $e->getMessage());
        }

        $param = [

                        ]
                    ]
                ],
            ],
        ];
        try {
            $client->put($url, $param);
        } catch (/Exception $e) {
            $this->info("===put模版出现错误==" . $e->getMessage());
        }

        $this->info("========= 创建模版成功 ========");

        // 创建index
        $url = config('scout.elasticsearch.hosts')[0] . '/' . config('scout.elasticsearch.index');
        try {
            $client->delete($url);
        } catch (/Exception $e) {

        }
        $param = [
