[英]Send an XML post request to a web server with CURL
I am trying to send a request to a web server using php and curl. 我正在尝试使用php和curl向Web服务器发送请求。 I haven't done something like this before and although there are many nice examples online I have some difficulties understanding some of the curl commands. 我之前没有做过类似的事情,虽然网上有很多不错的例子,但我对理解一些curl命令有些困难。
This is what I want to do: There is an established web service (for example: Web map service) and I want my php code to send a post XML request to this service. 这就是我想要做的:有一个已建立的Web服务(例如:Web地图服务),我希望我的php代码向此服务发送一个发布XML请求。 As a respond I want to get an XML file. 作为回应,我想获得一个XML文件。
This is what I have till now: 这就是我现在所拥有的:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, '');
/*curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));*/
/* curl_setopt($ch, CURLOPT_HEADER, 0);*/
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
/*curl_setopt($ch, CURLOPT_REFERER, '');*/
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$ch_result = curl_exec($ch);
curl_close($ch);
echo $ch_result;
As I said I am quite new in php and also in using curl and I think I am missing some concepts. 正如我所说,我在php中也很新,也使用curl,我想我缺少一些概念。 My questions are: 1) What is the string (link) that I have to put in the: 我的问题是:1)我必须放入的字符串(链接)是什么:
curl_setopt($ch, CURLOPT_URL, '');
Is it the host name of the service which I want to send the request? 它是我要发送请求的服务的主机名吗?
2) In row 6 the variable $xml contains the xml file that I want to send as a request. 2)在第6行中,变量$ xml包含我要作为请求发送的xml文件。 Is it correct or this variable is supposed to contain something else? 它是正确的还是这个变量应该包含其他内容?
3) In which cases do I need to use a httpheader or header (row3 and row4); 3)在哪些情况下我需要使用httpheader或header(row3和row4);
Thanks for the help. 谢谢您的帮助。 Dimitris 季米特里斯
Try it this way: 试试这种方式:
$url = 'https://android.googleapis.com/gcm/send';
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, "<xml>here</xml>" );
$result = curl_exec($ch);
curl_close($ch);

I think using the HTTP classes may be better suited for making HTTP requests. 我认为使用HTTP类可能更适合发出HTTP请求。

Also, there are specific WMS libraries for PHP, eg http://docs.huihoo.com/geoserver/1.6.0/Parsing%20and%20using%20WMS%20capabilities%20with%20PHP.html . 此外,还有适用于PHP的特定WMS库,例如http://docs.huihoo.com/geoserver/1.6.0/Parsing%20and%20using%20WMS%20capabilities%20with%20PHP.html 。
