注意post和get数据获取的区别
get
//初始化
$ch = curl_init();
//设置选项,包括URL
curl_setopt($ch, CURLOPT_URL, "http://www.jb51.net");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
//执行并获取HTML文档内容
$output = curl_exec($ch);
//释放curl句柄
curl_close($ch);
//打印获得的数据
print_r($output);
Post
$url = "http://localhost/web_services.php";
$post_data = array ("username" => "bob","key" => "12345");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// post数据
curl_setopt($ch, CURLOPT_POST, 1);
// post的变量
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$output = curl_exec($ch);
curl_close($ch);
//打印获得的数据
print_r($output);
