[英]Ajax call to Controller and XML response Symfony2
I'm new to Symfony2. 我是Symfony2的新手。 Now I want to implement my previous practice for ajax call using Symfony2.
现在,我想使用Symfony2实现我以前的ajax调用实践。
I want to make an ajax call to a server side code and get XML response and extract it. 我想对服务器端代码进行ajax调用,并获取XML响应并将其提取。 Here is what I do.
这是我的工作。
var data={
type:'1'
};
jQuery.ajax({
url: 'server_script/check.php', //load data
global: false,
type: "POST",
dataType: "xml",
data: data,
async: false,
success: load_data2
});
In flat php file I can catch that and using 在平面php文件中,我可以捕获并使用
$type=$_POST['type'];
In Symfony2 I'm making AJAX call by using 在Symfony2中,我通过使用AJAX进行呼叫
jQuery.ajax({
url: '{{ path('create_label') }}', //load data
global: false,
type: "POST",
dataType: "xml",
data: data,
async: false,
success: load_data2,
error: problem
});
And in Controller that comes from the create_label,I catch it using 在来自create_label的Controller中,我使用
$type->request->get('type');
I'm not sure yet though if it's really working. 我还不确定是否真的有效。 Got it from this link Link

Next in flat PHP I produce a XML response by 接下来在平面PHP中,我通过生成XML响应
header("Content-type: text/xml");
echo "<?xml version=\"1.0\" ?>\n";
echo "<Loadinglist>\n";
echo "</Loadinglist>";
It gave me a response that I extract in function load_data2(xmlindata)
method. 它给了我在
function load_data2(xmlindata)
方法中提取的响应。
Now I'm not able to make any valid XML response in Symfony2. 现在,我无法在Symfony2中进行任何有效的XML响应。 I tried few tricks but none of them are working.
我尝试了一些技巧,但没有一个起作用。 I want to send a XML response from Controller , catch it and extract in with the
load_data2
method. 我想从Controller发送一个XML响应,捕获它并使用
load_data2
方法提取。 If you have time please provide an wiki type answer that how the xml response work is done. 如果您有时间,请提供一个Wiki类型的答案,说明xml响应工作是如何完成的。
(NB In flat php I could check the XML response in console or firebug, will I be able to view the same in Symfony2 ) (注意,在平面php中,我可以在控制台或firebug中检查XML响应,我可以在Symfony2中查看该响应)
To get the POST parameter, it's better to be explicit and use $request->request->get('type')
. 要获取POST参数,最好是显式的并使用
$request->request->get('type')
。 This will only get the POST parameter 'type' and not the GET parameter 'type'. 这只会获取POST参数“ type”,而不会获取GET参数“ type”。
Next, a controller always returns a Response
. 接下来,控制器始终返回
Response
。 This class can be seen as a PHP port of the real HTTP response. 此类可以视为实际HTTP响应的PHP端口。 So you can tweak it to return XML.
因此,您可以对其进行调整以返回XML。
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class YourController // ...
{
function someAction(Request $request)
{
// ...
$response = new Response(<<<EOX
<?xml version="1.0" ?>
<Loadinglist>
</Loadinglist>
EOX
);
$response->headers->set('Content-Type', 'text/xml');
}
}
