本文实例讲述了PHP封装CURL扩展类。分享给大家供大家参考。具体如下:
ch_ = curl_init($url);
curl_setopt($this->ch_, CURLOPT_HEADER, 1);
curl_setopt($this->ch_, CURLOPT_RETURNTRANSFER , 1 );
}
/**
* @返回响应头
*/
public function ResponseHeader($url){
if (!function_exists('http_parse_headers')) {
function http_parse_headers ($raw_headers){
$headers = array();
foreach (explode("\n", $raw_headers) as $i => $h) {
$h = explode(':', $h, 2);
if (isset($h[1])) {
if(!isset($headers[$h[0]])) {
$headers[$h[0]] = trim($h[1]);
} else if(is_array($headers[$h[0]])) {
$tmp = array_merge($headers[$h[0]],array(trim($h[1])));
$headers[$h[0]] = $tmp;
} else {
$tmp = array_merge(array($headers[$h[0]]),array(trim($h[1])));
$headers[$h[0]] = $tmp;
}
}
}
return $headers;
}
}
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_);
$this->body_=$this->Execx();
$header_size = curl_getinfo($this->ch_, CURLINFO_HEADER_SIZE);
$this->response_header_ = substr($this->body_, $start = 0, $offset = $header_size);
$this->response_header_ = http_parse_headers($this->response_header_);
print_r($this->response_header_);
return $this->Close($this->body_);
}
/**
* @读取cookie
*/
public function LoadCookie($url,$cookie_file){
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_COOKIE, 1);
curl_setopt($this->ch_, CURLOPT_COOKIEFILE , $cookie_file);
$this->body_=$this->Execx();
return $this->Close($this->body_);
}
/**
* @写入cookie
*/
public function SaveCookie($url){
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_COOKIE, 1);
curl_setopt($this->ch_, CURLOPT_COOKIEFILE ,'cookie.txt');
curl_setopt($this->ch_, CURLOPT_COOKIEJAR , 'cookie.txt');
$this->body_=$this->Execx();
return $this->Close($this->body_);
}
/**
* @设置HEADER
*/
public function SetHeader($headers = null){
if (is_array($headers) && count($headers) > 0) {
curl_setopt($this->ch_, CURLOPT_HTTPHEADER, $headers);
}
}
/**
* @GET请求
*/
public function Get($url, array $params = array()) {
if ($params) {
if (strpos($url, '?')) {
$url .= "&".http_build_query($params);
}
else {
$url .= "?".http_build_query($params);
}
}
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_);
if (strpos($url, 'https') === 0) {
curl_setopt($this->ch_, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($this->ch_, CURLOPT_SSL_VERIFYPEER, 0);
}
$this->body_=$this->Execx();
return $this->Close($this->body_);
}
/**
* @POST请求
*/
public function Post($url, array $params = array()) {
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($this->ch_, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded"));
curl_setopt($this->ch_, CURLOPT_POST, true);
curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_);
if ($params) {
curl_setopt($this->ch_, CURLOPT_POSTFIELDS, http_build_query($params));
}
$this->body_=$this->Execx();
return $this->Close($this->body_);
}
/**
* @tips: google http head 方法
*/
public function Head($url, array $params = array()) {
$this->Start($url);
curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_);
curl_setopt($this->ch_, CURLOPT_RETURNTRANSFER , 0);
curl_setOpt($this->ch_,CURLOPT_NOBODY, true);
$this->body_=$this->Execx();
return $this->Close($this->body_);
}
/**
* @执行CURL会话
*/
public function Execx(){
return curl_exec($this->ch_);
}
/**
* @关闭CURL句柄
*/
public function Close($body_){
if ($body_ === false) {
echo "CURL Error: " . curl_error($body_);
return false;
}
curl_close($this->ch_);
return $body_;
}
}
