php通用扩展

图片处理扩展

https://packagist.org/packages/intervention/image
https://image.intervention.io/v2/introduction/installation
支持 Laravel 集成的图像处理和操作库

//安装
composer require intervention/image

代码示例

// 打开图像文件
$img = Image::make('public/foo.jpg');
//可以直接传入request请求的文件对象
$img = Image::make($request()->file('file'));
//或者传入 使用 response file 移动后返回的文件
$file=$request()->file('file')->move('路径','名字');
$img = Image::make($file);
// 调整图像实例的大小
$img->resize(320, 240);
// 自适应高度
$img->resize(300, null, function ($constraint) {
        $constraint->aspectRatio();
    });
// 插入水印
$img->insert('public/watermark.png');
// 以所需格式保存图像 第二个参数为质量可选  可选第三个参数修改文件格式
$img->save('public/bar.jpg',100);

使用自动加载类来实现

// 使用自动加载
require 'vendor/autoload.php';
//导入干预图像管理器类
use Intervention\Image\ImageManager;
//使用受青睐的驱动程序创建映像管理器实例
$manager = new ImageManager(['driver' => 'imagick']);
//以最终创建图像实例
$image = $manager->make('public/foo.jpg')->resize(300, 200);

使用静态

// 使用自动加载
require 'vendor/autoload.php';
//导入干预图像管理器类
use Intervention\Image\ImageManagerStatic as Image;
//使用喜爱的图像驱动程序进行配置（默认为gd）
Image::configure(['driver' => 'imagick']);
//你已经准备好出发了。。。
$image = Image::make('public/foo.jpg')->resize(300, 200);

集成成到laravel中去

在config/app.php中添加

// $providers数组中添加
Intervention\Image\ImageServiceProvider::class
//$aliases 数组中添加
'Image' => Intervention\Image\Facades\Image::class

默认情况下，Intervention Image 使用 PHP 的 GD 库扩展来处理所有图像。如果您想切换到 Imagick，您可以通过运行以下 artisan 命令之一将配置文件拉入您的应用程序。

在laralvel中发布配置

php artisan vendor:publish --provider="Intervention\Image\ImageServiceProviderLaravelRecent"
# laravel版本<=4的时候用这个
php artisan config:publish intervention/image

markdown处理

https://packagist.org/explore/?query=markdown
可以把markdown的内容转化为html

es扩展 (elasticsearch )

官网: https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/index.html

文档:
https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/getting-started-php.html

软件下载: https://elasticsearch.cn/download/

扩展安装
composer require elasticsearch/elasticsearch

ElasticSearch重置密码步骤（忘记密码的情况）

1.停止Elasticsearch服务
2.编辑elasticsearch.yml文件，设置以下两项为false;
	xpack.security.enabled: false
	xpack.security.transport.ssl.enabled: false
3.重启es服务，删除.security-7索引
	curl -XDELETE -u elastic:changeme http://localhost:9200/.security-7
3.关闭ES服务设置以下两项为true;
	xpack.security.enabled: true
	xpack.security.transport.ssl.enabled: true
4.重启es服务，进入es的bin目录下
	./elasticsearch-setup-passwords interactive
	依次设置每个账号密码即可

获取密码:
进入es安装目录的bin文件中执行一下命令会返回最新的密码
命令 : elasticsearch-reset-password -u elastic
默认用户名: elastic
密码: QhW4NJSQGzP13o2kVI6o
修改密码的其他命令
https://devpress.csdn.net/cloud-native/65195642aae4e179c0b77cc4.html

开启各种安全验证后需要ssl证书才能正常登录

xpack.security.enabled: true
xpack.security.enrollment.enabled: true
xpack.security.http.ssl:
  enabled: true
  keystore.path: certs/http.p12
xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12

证书位置 config\certs\http_ca.crt

config/es.php文件配置

return [
    'host'=>['https://127.0.0.1:9200'],
    'user'=>'elastic',
    'pwd'=>'VX_IuVXQ6_WcfmBO8Mxc',
];

//初始化
use Elastic\Elasticsearch\ClientBuilder;
use Elastic\Elasticsearch\Exception\ClientResponseException;
use Elastic\Elasticsearch\Exception\ServerResponseException;
$client = ClientBuilder::create()
    ->setHosts(config('es.host'))
    ->setBasicAuthentication(config('es.user'), config('es.pwd'))
    ->setCABundle('cacrt/http_ca.crt')
    ->build();

分词器要下载对应的版本
https://github.com/medcl/elasticsearch-analysis-ik
下载地址
https://github.com/medcl/elasticsearch-analysis-ik/releases

下载后解压到 plugins/ik 目录下面 重启 es即可

//创建映射
curl -XPOST http://localhost:9200/index/_mapping -H 'Content-Type:application/json' -d'
{
        "properties": {
            "content": {
                "type": "text",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_smart"
            }
        }
}'

使用案例

$response = WpOrg\Requests\Requests::get('https://api.github.com/events');

var_dump($response->body);
// string(42865) "[{"id":"15624773365","type":"PushEvent","actor":{...
//post请求
$response = WpOrg\Requests\Requests::post('https://httpbin.org/post');

//设置请求头
$url = 'https://api.github.com/some/endpoint';
$headers = array('Content-Type' => 'application/json');
$data = array('some' => 'data');
$response = WpOrg\Requests\Requests::post($url, $headers, json_encode($data));
