file_get_contents: get full response even on error

问题

Is it possible to make file_get_contents show me the actual response even if an error occurs?

It is difficult to debug otherwise. For instance, say you have the following code:

$url = 'https://api.twitter.com/oauth/request_token';
$data = array();

$options = array(
    'http' => array(
    'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
    'method'  => 'POST',
    'content' => http_build_query($data),
    ),
);
$context  = stream_context_create($options);
$result = @file_get_contents($url, false, $context);

var_dump($result);
var_dump($http_response_header);

This shows me NULL for the result and the HTTP headers, but I want to get the actual message Twitter sends back (should be something like Failed to validate oauth signature and token), which is what you get if you try to load https://api.twitter.com/oauth/request_token in your browser.

回答1:

There is a very simple switch for the context. just add this line to options:

'ignore_errors' => true

so you will get

$options = array(
    'http' => array(
    'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
    'method'  => 'POST',
    'content' => http_build_query($data),
    'ignore_errors' => true
    )
);
