使用curl加载xsl页面会返回实际的基数错误

we have a DITA XML application that produces on the fly xhtml and when viewed in the browser it looks fine.

我们有一个DITA XML应用程序,它可以即时生成xhtml,在浏览器中查看它看起来很好。

An example url is: http://livecontent.jordanpublishing.co.uk/content/en/FAMILY-201103311115/Family_FLJONLINE_FLJ_2009_07_4

一个示例网址是:http://livecontent.jordanpublishing.co.uk/content/en/FAMILY-201103311115/Family_FLJONLINE_FLJ_2009_07_4

If I try to load the url using curl I get the following error:

如果我尝试使用curl加载url,我会收到以下错误:

Error checking function parameter 3 in call transform:transform($fDoc, LiveContent-UI:get_xsl("ui/ui_skin.xsl", ""), LiveContent-UI:get_xsl_params(untyped-value-check[xs:string, $skin], $extra_params)): The actual cardinality for parameter 1 does not match the cardinality declared in the function's signature: LiveContent-Util:browser_from_user_agent($a as xs:string) xs:string.

and I am completely at a loss as to what is going wrong.

我完全不知道出了什么问题。

The PHP Curl code is as follows:

PHP Curl代码如下:

$ch = curl_init();
/**
* Set the URL of the page or file to download.
*/
curl_setopt($ch, CURLOPT_URL, 'http://onlineservices.letterpart.com/sitemap.xml;jsessionid=1j1agloz5ke7l?id=1j1agloz5ke7l');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec ($ch);
curl_close ($ch);

$xml = new SimpleXMLElement($data);
foreach ($xml->url as $url_list) {
    $url = $url_list->loc;
    echo $url ."<br>"; 
    //file_get_contents($url);




    echo $url ."<br>";   
    $ch = curl_init($url); //load the urls
                    echo $url ."<br>";  
            curl_setopt($ch, CURLOPT_TIMEOUT_m2, 20); //No need to wait for it to load. Execute it and go.
            curl_exec($ch); //Execute
            curl_close($ch); //Close it off

Can anyone help? I'm at a bit of a loss as this is way outside of my skill set.

有人可以帮忙吗?我有点失落,因为这超出了我的技能范围。

Thanks,

EDIT:

It was suggested that I added a User Agent so I added the following:

有人建议我添加了一个用户代理,所以我添加了以下内容:

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");

curl_setopt($ ch,CURLOPT_USERAGENT,“Mozilla / 4.0(兼容; MSIE 5.01; Windows NT 5.0)”);

I now get the following error in my logs:

我现在在日志中收到以下错误:

[13-May-2011 16:30:14] PHP Notice:  Use of undefined constant CURLOPT_TIMEOUT_m2 - assumed 'CURLOPT_TIMEOUT_m2' in /home/digital1/public_html/dev/sitemap.php on line 43

The two line in question here (43) is:

这里讨论的两条线(43)是:

curl_setopt($ch, CURLOPT_TIMEOUT_m2, 20); //No need to wait for it to load. Execute it and go.

I do seem to be having better luck using the Googlebot agent:

我似乎使用Googlebot代理有更好的运气:

Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)

as in I am actually getting content written to the screen but my logs are still showing these errors.

就像在我实际上将内容写入屏幕但我的日志仍然显示这些错误。

My immediate guess is that your Java app is expecting the User-Agent header to be set. Since Curl does not send a User-Agent header by default, you will need to set one. Try adding this above your option to set CURL_TIMEOUT_m2.

我的直接猜测是你的Java应用程序期望设置User-Agent标头。由于Curl默认情况下不发送User-Agent标头,因此您需要设置一个。尝试在选项上方添加此选项以设置CURL_TIMEOUT_m2。

curl_setopt($ch, CURLOPT_USERAGENT, "PHP/".PHP_VERSION );

If for some reason it does not like that User-Agent string, you might want to try using one from an actual browser.

如果由于某种原因它不喜欢User-Agent字符串,您可能想尝试使用实际浏览器中的一个。

EDIT:

Per your edit, this is because you've typoed the curl timeout constant. It should be CURLOPT_TIMEOUT_MS not CURLOPT_TIMEOUT_m2.

根据您的编辑,这是因为您已经错误地卷曲了卷曲超时常量。它应该是CURLOPT_TIMEOUT_MS而不是CURLOPT_TIMEOUT_m2。
