curl_exec() 需要参数 1,给定 sting
curl_exec() expects parameter 1, sting is given
我之前是这样用的file_get_content
if($html = @DOMDocument::loadHTML(file_get_contents($url))) {.. }
但切换到 curl 因为它更安全,但我收到错误
curl_exec() expects parameter 1, sting is given
我的代码
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$html = curl_exec($url);
curl_close($ch);
if($html) {
$xpath = new DOMXPath($html);
..
..
}
您正在执行 URL 字符串而不是 curl 句柄
$html = curl_exec($url);
改为
$html = curl_exec($ch);
错误是说你正在给 curl_exec
字符串,给它 curl 句柄。使用下面的代码
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$html = curl_exec($ch);
curl_close($ch);
if($html) {
$xpath = new DOMXPath($html);
..
..
}
