如何使在PHP中的异步GET请求? [英] How do I make an asynchronous GET request in PHP?
问题描述
我希望做一个简单的GET请求,另一个脚本不同的服务器上。我该怎么做呢?
I wish to make a simple GET request to another script on a different server. How do I do this?
在一种情况下,我只需要请求外部脚本,而不需要任何输出。
In one case, I just need to request an external script without the need for any output.
make_request('http://www.externalsite.com/script1.php?variable=45'); //example usage
在第二种情况下,我需要的文本输出。
In the second case, I need to get the text output.
$output = make_request('http://www.externalsite.com/script2.php?variable=45');
echo $output; //string output
说实话,我并不想与卷曲勾搭,因为这是不是真的卷曲的工作。我也不想利用HTTP_GET,因为我没有PECL扩展。
To be honest, I do not want to mess around with CURL as this isn't really the job of CURL. I also do not want to make use of http_get as I do not have the PECL extensions.
会的fsockopen工作?如果是这样,我怎么做没有在文件的内容读?难道就没有别的办法吗?
Would fsockopen work? If so, how do I do this without reading in the contents of the file? Is there no other way?
感谢所有
我要加入,在第一种情况下,我不想等待脚本返回任何东西。据我了解file_get_contents()函数将等待页面加载完全等?
I should of added, in the first case, I do not want to wait for the script to return anything. As I understand file_get_contents() will wait for the page to load fully etc?
推荐答案
的file_get_contents
将你想要做什么
$output = file_get_contents('http://www.example.com/');
echo $output;
编辑:一个方式来火了一个GET请求并立即返回
One way to fire off a GET request and return immediately.
从<带引号的href=\"http://petewarden.typepad.com/searchbrowser/2008/06/how-to-post-an.html\">http://petewarden.typepad.com/searchbrowser/2008/06/how-to-post-an.html
function curl_post_async($url, $params)
{
foreach ($params as $key => &$val) {
if (is_array($val)) $val = implode(',', $val);
$post_params[] = $key.'='.urlencode($val);
}
$post_string = implode('&', $post_params);
$parts=parse_url($url);
$fp = fsockopen($parts['host'],
isset($parts['port'])?$parts['port']:80,
$errno, $errstr, 30);
$out = "POST ".$parts['path']." HTTP/1.1\r\n";
$out.= "Host: ".$parts['host']."\r\n";
$out.= "Content-Type: application/x-www-form-urlencoded\r\n";
$out.= "Content-Length: ".strlen($post_string)."\r\n";
$out.= "Connection: Close\r\n\r\n";
if (isset($post_string)) $out.= $post_string;
fwrite($fp, $out);
fclose($fp);
}
这样做是开放的插座,火了一个GET请求,并立即关闭套接字,并返回。
What this does is open a socket, fire off a get request, and immediately close the socket and return.
