error when use file_get_contents on gae for php

[Chun-Ta Kung]

Hi,

I tested the sample code on this page: https://developers.google.com/appengine/docs/php/urlfetch/ 

the script is like this:

$data = array('data' => 'this', 'data2' => 'that');

$data = http_build_query($data);

$context =

    array("http"=>

      array(

        "method" => "get",

        "header" => "custom-header: custom-value\r\n" .

                    "custom-header-two: custome-value-2\r\n" ,

        "content" => $data

      )

    );

$context = stream_context_create($context);

$result = file_get_contents("http://app.com/path?query=update", false, $context);

However, I always get an error from server like below:

Warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: A non-recoverable error occurred during a database lookup. in C:\gae_work\helloworld\helloworld.php on line 14

Warning: file_get_contents(http://app.com/path?query=update): failed to open stream: php_network_getaddresses: getaddrinfo failed: A non-recoverable error occurred during a database lookup. in C:\gae_work\helloworld\helloworld.php on line 14

Even I use the simplest code, I will get the same error.

<?php 

file_get_contents('http://www.google.com');

?>

Any idea?

It sounds like your computer might be having trouble resolving hostnames-- have you noticed any other indications of that?

Hello Chun-Ta,

 

+1 on Amy's suggestion, that your local computer is most likely having difficulties with DNS resolving.

 

You can double check if this is the problem by trying to send http requests directly to IP addresses. For example, instead of attempting to access http://google.com, try accessing http://74.125.227.192 (this IP address is listed as one of the A records for google.com, you can double check this by looking up the DNS information for Google).

 

If the direct query to the IP address works, then your computer is failing to resolve DNS properly. If this still fails, you may have a more complex issue.
