使用 php 保存网址截图

Question

我每天都有一些网址，需要从这些网址中截取屏幕截图。我想在我的主机中保存特定的 url screenShot。现在我想在 localhost/wamp 和 linux 主机中尝试。

我尝试了一些库但没有成功。我想尝试 google api pagespeed v5 .

<?php
$url = 'mysite.com';
$response =     file_get_contents("https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=$url&screenshot=true");
$googlePagespeedObject = json_decode($response, true);
$screenshot = $googlePagespeedObject['screenshot']['data'];
$screenshot = str_replace(array('_','-'), array('/','+'), $screenshot);
echo "<img src=\"data:image/jpeg;base64,{$screenshot}\"     alt=\"Screenshot\" />";
file_put_contents('...', base64_decode($screenshot));

我的错误，没有任何成功的图像：

Warning: file_get_contents(https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=mysite.com&screenshot=true): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden in

Answer 1

这里是用于 php 截图的函数：

function ScreenShotUrl($url){
$link = $url ;
$name = parse_url($link)['host'];
$googlePagespeedData = file_get_contents("https://www.googleapis.com/pagespeedonline/v2/runPagespeed?url=$link&screenshot=true");
$googlePagespeedData = json_decode($googlePagespeedData, true);
$screenshot = base64_decode($googlePagespeedData['screenshot']['data']);
$data = str_replace('_','/',$googlePagespeedData['screenshot']['data']);
$data = str_replace('-','+',$data);
$decoded = base64_decode($data);
file_put_contents('images/screenshots/'.$name.'.jpg',$decoded);
$file_name = "$name.jpg";
}

我稍微修改了你的代码，试试这个代码。工作 example, saved image here

function ScreenShotUrl($url){
  $link = $url ;
  $name = parse_url($link)['host'];
  $resp = file_get_contents("https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=$link&screenshot=true");
  $resp = json_decode($resp, true);
  $data = str_replace('_','/',$resp['lighthouseResult']['audits']['final-screenshot']['details']['data']);
  $data = str_replace('-','+',$data);
  echo '<img src="' . $data . '" />';
  $img = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data)); 
  file_put_contents('tmp/'.$name.'.jpg', $img);
} 
$url = 'http://bajukakilima.com'; 
ScreenShotUrl($url);
