Question

我是卷曲的新人，我无法找到答案。我想获取页面的http状态，所以我使用

$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);

但如果有重定向（例如301重定向到另一个页面，它会给我200个答案），这不起作用，因为curlinfo_http_code给出了最后收到的HTTP代码

知道如何获得第一个收到的http代码吗？感谢

Answer 1

您需要使用CURLOPT_FOLLOWLOCATION = 0配置curl

Answer 2

我实现这一目标的方法是让PHP查询带有不同返回码的INI文件，并用可读的东西替换它们

<?php
$ch = curl_init(); // create cURL handle (ch)
if (!$ch) {
    die("Couldn't initialize a cURL handle");
}
// set some cURL options
$ret = curl_setopt($ch, CURLOPT_URL,            "http://mail.yahoo.com");
$ret = curl_setopt($ch, CURLOPT_HEADER,         1);
$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
$ret = curl_setopt($ch, CURLOPT_TIMEOUT,        30);

// execute
$ret = curl_exec($ch);

if (empty($ret)) {
    // some kind of an error happened
    die(curl_error($ch));
    curl_close($ch); // close cURL handler
} else {
    $info = curl_getinfo($ch);
    curl_close($ch); // close cURL handler

    if (empty($info['http_code'])) {
            die("No HTTP code was returned"); 
    } else {
        // load the HTTP codes
        $http_codes = parse_ini_file("HTMLCodes.ini");

        // echo results
        echo "The server responded: <br />";
        echo $http_codes[$info['http_code']];
    }

}
?> 

example of the ini file with return codes

[Informational 1xx]
100="Continue"
101="Switching Protocols"

[Successful 2xx]
200="OK"
201="Created"
202="Accepted"
203="Non-Authoritative Information"
204="No Content"
205="Reset Content"
206="Partial Content"

[Redirection 3xx]
300="Multiple Choices"
301="Moved Permanently"
302="Found"
303="See Other"
304="Not Modified"
305="Use Proxy"
306="(Unused)"
307="Temporary Redirect"

用重定向卷曲http代码
