我正试图使用curl和php将动态生成的图像下载到我的服务器上，但由于某种原因，我一直失败有人能帮忙吗。。。下面是我的代码
function download_image($image_url){
$ch = curl_init($image_url);
// curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1000); // some large value to allow curl to run for a long time
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
curl_setopt($ch, CURLOPT_WRITEFUNCTION, "curl_callback");
curl_setopt($ch, CURLOPT_VERBOSE, true); // Enable this line to see debug prints
curl_exec($ch);
curl_close($ch); // closing curl handle
}
/** callback function for curl */
function curl_callback($ch, $bytes){
global $fp;
$len = fwrite($fp, $bytes);
// if you want, you can use any progress printing here
return $len;
}
$image_file = "ram.png";
$fp = fopen ($image_file, 'w+'); // open file handle
download_image("http://chart.apis.google.com/chart?chl=30%&chs=300x120&cht=gm&chco=77AB10,FFFF00|FF0000&chd=t:30&chf=bg,s,232526");
fclose($fp);
对于这个url，当在url中使用&时，使用htmlspecialchars_decode可能会有所帮助。
$url = htmlspecialchars_decode("http://chart.apis.google.com/chart?chl=30%&chs=300x120&cht=gm&chco=77AB10,FFFF00|FF0000&chd=t:30&chf=bg,s,232526");
download_image($url);
尝试在此处删除编码的符号：
download_image("http://chart.apis.google.com/chart?chl=30%&chs=300x120&cht=gm&chco=77AB10,FFFF00|FF0000&chd=t:30&chf=bg,s,232526");
所以它看起来像：
download_image("http://chart.apis.google.com/chart?chl=30%&chs=300x120&cht=gm&chco=77AB10,FFFF00|FF0000&chd=t:30&chf=bg,s,232526");
这段代码对我来说很好
$ch = curl_init('http://soundcheck.xyz:8000/playingart?sid=1?'.$fresh);
var_dump($ch);
$fp = fopen('/home/soundcheck/public_html/images/artwork.png', 'wb');
curl_setopt($fp, CURLOPT_FRESH_CONNECT, TRUE);
curl_setopt($fp, CURLOPT_FORBID_REUSE, TRUE);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
