錯誤: Warning: fopen() [function.fopen]: Unable to find the wrapper "https" - did you forget to enable it when you configured PHP?
解決方案有3:
1.windows下的PHP,只需要到php.ini中把extension=php_openssl.dll前面的;刪掉,重啟服務就可以了。
2.linux下的PHP,就必須安裝openssl模塊,安裝好了以後就可以訪問了。
3.如果服務器你不能修改配置的話,那麼就使用curl函數來替代file_get_contents函數,當然不是簡單的替換啊。還有相應的參數配置才能正常使用curl函數。
對curl函數封裝如下:
復制代碼 代碼如下:
function http_request($url,$timeout=30,$header=array()){
if (!function_exists('curl_init')) {
throw new Exception('server not install curl');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
if (!emptyempty($header)) {
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
}
$data = curl_exec($ch);
list($header, $data) = explode("\r\n\r\n", $data);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 301 || $http_code == 302) {
$matches = array();
preg_match('/Location:(.*?)\n/', $header, $matches);
$url = trim(array_pop($matches));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
$data = curl_exec($ch);
}
if ($data == false) {
curl_close($ch);
}
@curl_close($ch);
return $data;
}
