[PHP知识库]PHP中用CURL实现GET和POST请求

??

CURL 发送 GET 请求

function?curl_get_request($url,$data=null){
	if(is_array($data)){
		$data?=?http_build_query($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);//不返回头部信息
	if($data!=null){
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);//设置Agent
	}
	$data?=?curl_exec($ch);
	curl_close($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	return?$data;
}

CURL 发送 POST 请求

function?curl_post_request($url,$data=null){
	if(is_array($data)){
		$data?=?http_build_query($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);//不返回头部信息
	curl_setopt($ch,?CURLOPT_POST,?1);
	if($data!=null){
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);
	}
	$data?=?curl_exec($ch);
	curl_close($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	return?$data;
}

封装GET和POST请求

function?curl_request($url,$data=null,$method="GET"){
	if(is_array($data)){
		$data?=?http_build_query($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);//不返回头部信息
	if(strtolower($method)!='get'){
		curl_setopt($ch,?CURLOPT_POST,?1);
	}
	if($data!=null){
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);
	}
	$data?=?curl_exec($ch);
	curl_close($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	return?$data;

}

CURL 使用 COOKIE 实现模拟用户登录爬取信息

//$cookie?cookie文件链接
function?curl_request($url,$data=null,$cookie='',$method='GET'){
	if(is_array($data)){
		?$data?=?http_build_query($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);
	if($method!='GET'){
		curl_setopt($ch,?CURLOPT_POST,?1);
	}
	if($data!=null){
		
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);
	}
	$cookie_file?=?file_get_contents($cookie);
	curl_setopt($ch,?CURLOPT_COOKIE,?$cookie_file);
	$data?=?curl_exec($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	curl_close($ch);
	
	return?$data;
}

CURL加请求header参数

function?curl_get_request($url,$data=null,$header=null){
	if(is_array($data)){
		$data?=?http_build_query($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);//不返回头部信息
	if($data!=null){
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);//设置Agent
	}
	if($header!=null){
	????/**
	?????????$header?=?array(
???????????????　　?'api-key:'.$key,
???????????????　　?'authorization:'.$authorization,
??????????????????);
	????**/
	???curl_setopt($ch,?CURLOPT_HTTPHEADER,?$header);
	}
	$data?=?curl_exec($ch);
	curl_close($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	return?$data;
}

CURL 发送JSON数据

function?curl_get_request($url,$data=null){
	if(is_array($data)){
		$data?=?json_encode($data);
	}
	$ch?=?curl_init();
	curl_setopt($ch,?CURLOPT_URL,?$url);
	curl_setopt($ch,?CURLOPT_HEADER,?false);//不返回头部信息
	if($data!=null){
		curl_setopt($ch,?CURLOPT_POSTFIELDS,?$data);	
	}
	curl_setopt($ch,?CURLOPT_RETURNTRANSFER,1);??//结果是否显示出来，1不显示，0显示????
	//判断是否https
	if(strpos($url,'https://')!==false){
		curl_setopt($ch,?CURLOPT_SSL_VERIFYPEER,?false);
		curl_setopt($ch,?CURLOPT_SSL_VERIFYHOST,?false);
		$UserAgent?=?'Mozilla/4.0?(compatible;?MSIE?7.0;?Windows?NT?6.0;?SLCC1;?.NET?CLR?2.0.50727;?.NET?CLR?3.0.04506;?.NET?CLR?3.5.21022;?.NET?CLR?1.0.3705;?.NET?CLR?1.1.4322)';
		curl_setopt($ch,?CURLOPT_USERAGENT,?$UserAgent);//设置Agent
	}
	curl_setopt($ch,?CURLOPT_HTTPHEADER,
　　　　　　array(
　　　　　　'Content-Type:?application/json;?charset=utf-8',
　　　　　　'Content-Length:'?.?strlen($data))
　　　　??);
????	
	$data?=?curl_exec($ch);
	curl_close($ch);
	if($data?===?FALSE)?
	{?
	??$data?=?"curl?Error:".curl_error($ch);
	}?
	return?$data;
}
