chrome-php(一款php模拟chrome或chrome浏览器的插件)

一、安装

Mac：首先安装chromedriver

brew tap homebrew/cask
brew cask install chromedriver

brew cask install chromium

brew cask reinstall chromium

引入包地址：https://github.com/chrome-php/headless-chromium-php

使用常见的错误：

Exception 'RuntimeException' with message 'Chrome process stopped before startup completed. Additional info: sh: chromium-browser: command not found'

使用说明：这个是由于你配置里面引入包的地址不对正确使用如下：
$browserFactory = new BrowserFactory("/Applications/Chromium.app/Contents/MacOS/chromium");
$browser = $browserFactory->createBrowser(['noSandbox' => $sandBox,
                                            'headless'  => true,
                                            'connectionDelay' => 0.8,
                                            'debugLogger'=> 'php://stdout']);
$page = $browser->createPage();
$page->navigate($url)->waitForReload();
$browser->close();

安装可以参考的地址：

二、包的引入：

composer require chrome-php/chrome

https://packagist.org/packages/chrome-php/chrome

三、各使用方法

1、模拟浏览器访问

$browserFactory = new BrowserFactory("/Applications/Chromium.app/Contents/MacOS/chromium");
$browser = $browserFactory->createBrowser(['noSandbox' => $sandBox,
                                            'headless'  => true,
                                            'connectionDelay' => 0.8,
                                            'debugLogger'=> 'php://stdout']);
$page = $browser->createPage();
$page->navigate($url)->waitForReload();
$browser->close();

2、浏览器截图

$browserFactory = new BrowserFactory("/Applications/Chromium.app/Contents/MacOS/chromium");
$browser = $browserFactory->createBrowser(['noSandbox' => $sandBox,
                                            'headless'  => true,
                                            'connectionDelay' => 0.8,
                                            'debugLogger'=> 'php://stdout']);
$page = $browser->createPage();
$page->navigate($url)->waitForReload();

if ($sleepTime) {
    sleep(6); // 6s等待资源加载及渲染完成，一般异步处理的脚本需要等待
}

$x = 10;$y = 10;//离X、Y的边距
$width = 100;$height = 100;//截图的宽高
$clip = new Clip($x, $y, $width, $height);
$screenshot = $page->screenshot([
'clip'  => $clip
    ]);
$screenshot->saveToFile('save-address.jpg');//地址保存的地址

问题：在liunx上有的截图可能会出现中文乱码，是因为系统缺少中文字体，可以安装yum install cjkuni-uming-fonts cjkuni-ukai-fonts 系统装字体

三、生成pdf文件，前面一样的后面加：

$options = [
            'landscape'       => true,  // default to false
            'printBackground' => true,   // default to false
            'displayHeaderFooter' => true, // default to false
            'preferCSSPageSize' => true, // default to false ( reads parameters directly from @page )
            'marginTop' => 0.0, // defaults to ~0.4 (must be float, value in inches)
            'marginBottom' => 1.4, // defaults to ~0.4 (must be float, value in inches)
            'marginLeft' => 5.0, // defaults to ~0.4 (must be float, value in inches)
            'marginRight' => 1.0 // defaults to ~0.4 (must be float, value in inches)
        ];
        $pdf = $page->pdf($options);

        // 文件保存地址
        $pdf->saveToFile($outputImgFullPath);

四、加载js:

$page->addScriptTag([
'url' => 'https://code.jquery.com/jquery-3.3.1.min.js'
])->waitForResponse();

$page->evaluate('$(".my.element").html()');//计算页面上线文给定字符串
