PHP curl

这是PHP的CURL模拟浏览器去发送POST提交，首先我们看下test.php这是用来发送POST提交的程序，代码如下

<?php
$remote = "http://localhost/curl/post.php";
$nameArr = array("a","b","c","d","e");

for($i=0;$i<10;$i++) {
$post_data = array (
    "username" => $nameArr[rand(0,5)].rand(0,1000000),
    "email" => rand(100000,20000000)."@qq.com",
    "password" => "111111111",
    "confirm_password" => "1211111111",
    "extend_field2" => "654333311257",
    "extend_field3" => "0551-5588774",
    "extend_field4" => "0551-5588774",
    "extend_field5" => "13865498754",
    "sel_question" => "friend_birthday",
    "passwd_answer" => "1990-01-28",
    "agreement" => 1,
    "act" => "act_register"
);


$ch = curl_init($remote);
//$fp = fopen($local,"w");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
//curl_setopt($cp, CURLOPT_FILE, $fp);
//curl_setopt($cp, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$out =curl_exec($ch);
//$info = curl_getinfo($cp);
//echo "获取". $info["url"] . "耗时". $info["total_time"] . "秒";
curl_close($ch);
//fclose($fp);
print_r($out);
}
?>

那个 post.php其实什么都没有就是用来接收test.php传递过来的数据的

<?php
print_r($_POST);
echo "<hr>";
?>

大家可以试试看得到什么效果。记得PHP要开启CURL。（PS：今天发现一个问题就是向不是PHP的程序发送数据时，需要http_build_query用这个函数处理下数据，然后就可以正常接收了，我测试的是ASP程序，其他不清楚，估计都是需要的。）

下面这个是通过CURL来远程下载，直接上代码，自己可以去运行看效果，PHP虽然很多方法可以进行远程下载，但是本人觉得CURL速度最快。

<?php
$remote = "http://ptts.iflytek.com/test.wav";
$local = "C:/a.wav";
/*$nameArr = array("a","b","c","d","e");

for($i=0;$i<10;$i++) {
$post_data = array (
    "username" => $nameArr[rand(0,5)].rand(0,1000000),
    "email" => rand(100000,20000000)."@qq.com",
    "password" => "111111111",
    "confirm_password" => "1211111111",
    "extend_field2" => "654333311257",
    "extend_field3" => "0551-5588774",
    "extend_field4" => "0551-5588774",
    "extend_field5" => "13865498754",
    "sel_question" => "friend_birthday",
    "passwd_answer" => "1990-01-28",
    "agreement" => 1,
    "act" => "act_register"
);*/


$cp = curl_init($remote);
$fp = fopen($local,"w");
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($cp, CURLOPT_FILE, $fp);
curl_setopt($cp, CURLOPT_HEADER, 0);
//curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_exec($cp);
$info = curl_getinfo($cp);
echo "获取". $info["url"] . "耗时". $info["total_time"] . "秒";
curl_close($cp);
//fclose($fp);
//print_r($out);
//}
?>

如果是get请求，页面发生跳转的

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);//获取跳转后的页面
$content =curl_exec($ch);
curl_close($ch);

不需要https信任验证 

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);   

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,0);
