rest request to ebay doesn't return xml object

[jrough]

I don't know if the problem is my windows firewall blocking my return request.
I just got Windows 8 touch and I can't figure out how to disable it as administrator.

I also just installed WAMP. I got apache & php to run. I checked in services and phpinfo.
So that checks.

This is the error I get when I hit the page in www.

asXML(); $parsed_xml = simplexml_load_string($request); print_r($parsed_xml); $xml = new SimpleXmlElement($parsed_xml); if (strpos($request,ERROR) === false){ $result= $parsed_xml->item->title; $title= (string) $result; echo $title; }else{ $request=substr($request,strpos($request,'Errors', (strlen($request)-strpos($request,'Errors')))); echo $request . "
"; }

If someone else can run this html page to see if it is the firewall?
I don't mind sharing my appid since this is just a test case to see if I can get it to work.
I am trying to output the xml object to see if it got any find results.
It seems not. The only part of the request that might be wrong is the product ID.
I can't figure out how to set the line where type=UPC in correct syntax but I don't know how to error check this.
Thanks very much in advance,

}

in case you need to see the format of the xml response object I don't know if it helps but this is the structure from ebay.

I reread the Ebay API and discovered you can use UPC code as productId.
I fixed the productId and doublechecked the request syntax and everything looks right.

I am getting the following reponse in my page? Is there an error in Simple XML capture part of the code?
I checked my phpinfo and simplexml is included. I just want to see some results anywhere I don't care if there is errors I just want some results returned.

I don't know why it is printing out the php code?

item->title; $title= (string) $result; echo $title; }else{ $request=substr($request,strpos($request,'Errors', (strlen($request)-strpos($request,'Errors')))); echo $request . "
"; } ?>
I just want to see if I'm getting the XML object back. It is just returning my code with no errors.
asXML(); $parsed_xml = simplexml_load_string($request); print_r($parsed_xml); $xml = new SimpleXmlElement($parsed_xml); if (strpos($request,ERROR) === false){ $result= $parsed_xml->item->title; $title= (string) $result; echo $title; }else{ $request=substr($request,strpos($request,'Errors', (strlen($request)-strpos($request,'Errors')))); echo $request . "

"; }

error_reporting(E_ALL);
define("ERROR", "Error");

}

I'm not even getting any errors from Error ALL? Do I have to urlencode the request?
Thanks

[jrough]

Okay, I got a proper error message:
( ! ) Warning: file_get_contents(http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByProduct&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=removed&GLOBAL-ID=EBAY-US&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&productId=753759077600): failed to open stream: HTTP request failed! HTTP/1.0 500 Internal Server Error in C:\wamp\www\ebay_test_jrough.php on line 27

Line 27 is the file_get_contents requqest line?

[bradgrafelman]

Try visiting the URL in a browser or otherwise dumping the full response; just because you receive a 500 code response doesn't mean the response won't contain a body with helpful debugging information.

EDIT: Also, not sure how much of the info in that URL was meant to be kept private, but you might want to consider that before posting URLs that potentially contain secret/private "key" values, etc.

[jrough]

This is just a test, not worried about security.
I tried print_r($request); as a dump of the request but it doesn't get past the error in line 27 at all.
It says internal server error? Is that because I can't test a rest request on a localhost? tnx,

[bradgrafelman]

If you can't get your code to work, did you...

That is how I'm viewing the results. I don't know how to do the command line php on a pc.
I tried it in a different browser using firefox and checked in firebug. No messages.
I was checking it in the chrome browser. ok wait I didn't understand you want me to put the url in the location window. just a second I'll try it.
I guess I need to read up on the authentication. There are 3 other keys. maybe I need all of them not just this one? thanks,

Very cool I got a response.
