Php 通过curl_setopt()获取文件并将其写入.PNG格式
我需要从我正在通过Php 通过curl_setopt()获取文件并将其写入.PNG格式,php,curl,fwrite,Php,Curl,Fwrite,我需要从我正在通过curl\u setopt()加载的文件中创建一个.PNG文件 将创建.PNG,但不能再读取。 因此,我的想法是,$rawdata没有正确的内容 // Function to download a file (needed in one of the programming missions) function htsGetFile($url, $filename) { $cookiefile = "cookie.txt"; $ch = curl_init()
curl\u setopt()
加载的文件中创建一个.PNG
文件将创建
.PNG
,但不能再读取。因此,我的想法是,
$rawdata
没有正确的内容
// Function to download a file (needed in one of the programming missions)
function htsGetFile($url, $filename) {
$cookiefile = "cookie.txt";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0');
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile); // Cookiejar on creation, cookiefile on use
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // We need tot get the data back.
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //Will not check the ssl sertification.
$rawdata = curl_exec($ch);
if(file_exists($filename)){
unlink($filename);
}
$fp = fopen($filename, 'wb');
fwrite($fp, $rawdata);
fclose($fp);
if(curl_errno($ch)) {
return false;
} else {
return $rawdata;
}
curl_close ($ch);
}
$username = "*******";
$password = "*******";
$url = "https://www.domain/path/";
$file = "download.png";
if (htsLogin($username, $password))
if (htsGetHTML($url) !== false)
if (htsGetFile($url, $file) !== false)
$img = htsGetFile($url, $file);
else
echo 'Getting file went wrong.';
else
echo 'Getting page went wrong.';
else
echo 'Can\'t login.';
尝试
file\u put\u contents($file\u name,$rawdata)
而不是
$fp = fopen($filename, 'wb');
fwrite($fp, $rawdata);
fclose($fp);
或者
base64\u encode($rawdata)
在这两种变体中检查png
的内容,在一个太像记事本的记事本++中查看发生了什么。@justonUndermillion,我做了,我得到了一个磨损的文本,我想他们称之为二进制代码。但我看到了一些东西,比如边框背景是黑色的,里面有一个带有nulladdcurl_setopt($ch,CURLOPT_HEADER,0)的文本代码>请看这里,这两种变体中的或base64_encode($rawdata)是什么意思?
如果文件将被破坏,请尝试文件内容($file_name,base64_encode($rawdata))代码>
