php使用curl如何实现简单模拟提交表单功能的代码实例

//初始化curl

$ch= curl_init();

$url='xxx'

$option= [

 CURLOPT_URL =>$url,

 CURLOPT_HEADER => 1,

 CURLOPT_RETURNTRANSFER => 1,

];

curl_setopt_array($ch,$option);

$output= curl_exec($ch);

preg_match_all('/Set-Cookie: (.*);/i',$output,$str);//正则匹配

//如果有token的话就获取token

preg_match('/token = "(.*)"/i',$output,$token);

if(empty($str)) {

 returnfalse;

}

$cook=$str[1];

$cookie= implode('',$cook);

$up_url='xxx'

$post_data= [

 'name'=>'test_',

 'tel'=>�',

 'email'=>'[email protected]',

 'message'=>'this is my message;',

 '_token'=>$token[1],

];

$options= [

 CURLOPT_URL =>$up_url,

 CURLOPT_RETURNTRANSFER => 1,

 CURLOPT_HEADER => 1,

 CURLOPT_USERAGENT  =>"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36  (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36",

 CURLOPT_COOKIESESSION => 1,

 CURLOPT_POST => 1,

 CURLOPT_POSTFIELDS =>$post_data,

 CURLOPT_COOKIE =>$cookie

];

curl_setopt_array($ch,$options);

$res= curl_exec($ch);

// $info = curl_getinfo($ch);

if($res=== FALSE) {

 p('curl Error: '. curl_error($ch));

}

curl_close($ch);

p($res);
