常用封装curl函数​httpGet() 、httpPost()

常用封装curl函数

/**
* curl类,get方式提交数据到指定url
* @param $url: 提交数据的地址
* @param @data: 提交的数据
* @return json
*/
function httpGet($url){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, 500);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);//在服务器还没有开启https验证的时候跳过验证
    $res = curl_exec($curl);
    curl_close($curl);
    return $res;
}

/**
* post提交信息到地址(application/x-www-form-urlencoded方式)
* @param $url: 提交数据的地址
* @param $data: 提交的数据  
* @param $useCert:包含证书路径的数组,如果存在则启用证书
* @return json
*/
function httpPost($url,$data,$useCert=''){
  // echo ."````".dirname(dirname(__FILE__));exit;
	$ch = curl_init();
	 curl_setopt($ch, CURLOPT_URL,$url);
	 curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
	 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
	 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
	 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.33 Safari/537.36');
	 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
	 curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
	 if($data != ""){
	 	curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
	 }
    if(!empty($useCert)){
            //设置证书
            //使用证书:cert 与 key 分别属于两个.pem文件
            curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');
            curl_setopt($ch,CURLOPT_SSLCERT, $useCert['apiclient_cert']);
            curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');
            curl_setopt($ch,CURLOPT_SSLKEY, $useCert['apiclient_key']);
    }
	 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	 $tmpInfo = curl_exec($ch);
	 
	 if (curl_errno($ch)) {
		return ("curl_error: ".curl_error($ch));
	 }
	 curl_close($ch);
	 return $tmpInfo;
}

又一个封装curl函数 

//把请求发送到微信服务器换取二维码 // $result = httpRequest( $url, $param_json_arr ,"POST");
  function httpRequest($url, $data='', $method='GET'){
    $curl = curl_init();  
    curl_setopt($curl, CURLOPT_URL, $url);  
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);  
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);  
    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);  
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);  
    curl_setopt($curl, CURLOPT_AUTOREFERER, 1);  
    if($method=='POST')
    {
        curl_setopt($curl, CURLOPT_POST, 1); 
        if ($data != '')
        {
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);  
        }
    }

    curl_setopt($curl, CURLOPT_TIMEOUT, 30);  
    curl_setopt($curl, CURLOPT_HEADER, 0);  
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
    $result = curl_exec($curl);  
    curl_close($curl);  
    return $result;
  } 

添加cookie

    $cookie_file = dirname(__FILE__) . '/cookie.txt';

	
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
