我怎样才能获得和处理从PHP API响应 [英] How can I get and process a response from a PHP API

问题描述

好吧，我会努力保持这个短。我做一个简单的PHP API可以通过AJAX通过JavaScript或JQuery的做的请求，但是我要让使用PHP请求。什么是做到这一点的最好方法是什么？使用的file_get_contents（）函数或CURL？如果是的话我怎么做卷曲通过的API需要我用GET POST没有。我也知道响应是XML，我怎么再处理响应一旦回来？

这问题可能已经问了很多次，审查了很多的问题和答案然而，当他们并不是专门针对我的这一个，所以请与请看到这个链接我可以保证它没有获得答案的需求ŧ回答充满了一个问题，他们中的很多正在无论从Facebook的API或其他API请求没有做什么我使用的API一样。

解决方案

 函数的getXML（）
{ $ CH = curl_init（）;
 curl_setopt（$ CH，CURLOPT_URLhttp://127.0.0.1/index.html）;
 curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，真正的）;
 curl_setopt（$ CH，CURLOPT_USERPWD，用户：密码）;
 curl_setopt（$ CH，CURLOPT_HTTPAUTH，CURLAUTH_ANY）;
 $解析度= curl_exec（$ CH）; 返回$资源;}    $ xml_data =的getXML（）;    $ DOC =新的DOMDocument（）;
    $ doc-＆GT;的loadXML（$ xml_data）;    $ WMS = $ doc-＆GT;的getElementsByTagName（'WowzaMediaServer'）;
    $ wmstotalactive = $ wms-＆GT;项（0） - ＆GT;的getElementsByTagName（ConnectionsCurrent） - ＆GT;项（0） - ＆GT;的nodeValue;
    $ wmstotaloutbytes = $ wms-＆GT;项（0） - ＆GT;的getElementsByTagName（MessagesOutBytesRate） - ＆GT;项（0） - ＆GT;的nodeValue;
 

让你从XML从ConnectionsCurrent键和MessagesOutBytesRate值提取

如果您的链接并不需要权威性删除：

curl_setopt（$ CH，CURLOPT_USERPWD，用户：密码）;

curl_setopt（$ CH，CURLOPT_HTTPAUTH，CURLAUTH_ANY）;

Ok I will try and keep this short. I'm making a request to a simple PHP API which can be done by AJAX through Javascript or JQuery, however I want to make the request using PHP. What is the best way to do this? Using the file_get_contents() function or CURL? If so how do I do it through CURL as the API requires I use GET not POST. Also the response I know is in XML, how do I then process the response once it comes back?

This question may have been asked many times, however when reviewing a lot of the questions and answers they are not specific to my needs on this one so please no answers with "Please see this link" as I can guarantee it won't answer the question in full as a lot of them are making requests from either Facebook API or another API that does not do what the API I am using does.

解决方案

function  getXML()
{

 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, "http://127.0.0.1/index.html");
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_USERPWD, "user:password");
 curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
 $res = curl_exec($ch);

 return  $res;

}

    $xml_data = getXML();

    $doc = new DOMDocument();
    $doc->loadXML($xml_data);

    $wms = $doc->getElementsByTagName('WowzaMediaServer');


    $wmstotalactive = $wms->item(0)->getElementsByTagName("ConnectionsCurrent")->item(0)->nodeValue;
    $wmstotaloutbytes = $wms->item(0)->getElementsByTagName("MessagesOutBytesRate")->item(0)->nodeValue;

so you extracted from xml the value from ConnectionsCurrent key and MessagesOutBytesRate .

If your link does not need to auth remove :

curl_setopt($ch, CURLOPT_USERPWD, "user:password");

curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
