CURL請求

一般的CURL

//1.啓動一個curl事務，也可以此時不設置，通過curl_setopt($curl,CURLOPT_URL,'http://unun.in')進行設置
//$curl = curl_init('https://pic3.zhimg.com/e8fdec7f795d217f16faa1e2cd100522_l.png');
$curl = curl_init('https://www.baidu.com');
//2.可以多次調用curl_setopt進行設置
//curl_setopt($curl);
//爲真時，設置curl_exec()返回的數據以文件流（字符串）的形式返回，而不是直接輸出
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
//curl_setopt($curl,CURLOPT_HEADER,0);

//對於https協議出錯的可以嘗試設置本項
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

//3.使用curl_exec執行事務
$res = curl_exec($curl);
//header('Content-Type:image/png');
echo $res;
//4.關閉curl
curl_close($curl);

帶文件頭的CURL

$curl = curl_init();
//curl_setopt($curl,CURLOPT_URL,'https://www.zhihu.com/people/wangerhei/activities');
curl_setopt($curl,CURLOPT_URL,'https://www.zhihu.com/r/answers/43605938/comments');
//設置結果不直接顯示
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
//準備header的數據
$header = array();

CURL上傳

//1.啓動一個curl事務

//2.可以多次調用curl_setopt進行設置
//請求地址
curl_setopt($curl,CURLOPT_URL,'http://localhost/oop/3.php');
//爲真時，設置curl_exec()返回的數據以文件流（字符串）的形式返回，而不是直接輸出
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
//爲真時會發送POST請求
curl_setopt($curl,CURLOPT_POST,1);
//設置POST過去的數據
//普通的post請求
///$data = array('a'=>'abc','b'=>222);
//curl_setopt($curl,CURLOPT_POSTFIELDS, $data);


//如果通過CURLOPT_POSTFIELDS設置上傳文件的話，在PHP5.5以後的版本需要設置CURLOPT_SAFE_UPLOAD爲假，爲使用不安全模式
curl_setopt($curl,CURLOPT_SAFE_UPLOAD,0);
//單文件上傳
//$data = array('a'=>'abc','b'=>222,'file'=>'@./1.png');
//多文件上傳
$data = array('a'=>'abc','b'=>222,'file[0]'=>'@./1.png','file[1]'=>'@./2.png;type=image/png');
curl_setopt($curl,CURLOPT_POSTFIELDS, $data);



//3.使用curl_exec執行事務
$res = curl_exec($curl);
//4.關閉curl
