Fosrestbundle: No matching accepted Response format could be determined

[Gnucki]

Since the last updates, I got a "No matching accepted Response format could be determined" when I call a route with an url starting with /api.

Here is the configuration:

# FOSRest Configuration
fos_rest:
    param_fetcher_listener: force
    routing_loader:
        default_format: json
    access_denied_listener:
        json: true
    format_listener:
        rules:
            - { path: ^/api, priorities: ['json', 'html', '*/*'], fallback_format: json, prefer_extension: true }
            - { path: ^/, priorities: ['html', '*/*'], fallback_format: html, prefer_extension: true }

I didn't change anything.

can you also paste some information on the request?

If I call /api/participations.json?search=060606 it works of course.

[Gnucki]

I investigated a bit on my problem. Seems the new system works differently with the accept header. When there is no Accept header containing, for instance application/json, a */* is returned by the following code (with my configuration):

// FOS\RestBundle\Util\FormatNegotiator

/**
 * Detect the request format based on the priorities and the Accept header
 *
 * @param   Request         $request          The request
 * @return  void|string                       The format string
 */
public function getBestMediaType(Request $request)
{
    // ...

    $mimeTypes = $this->formatNegotiator->normalizePriorities($options['priorities']);
    $mediaType = $this->formatNegotiator->getBest($acceptHeader, $mimeTypes);
    if (null !== $mediaType) {
        return $mediaType->getValue(); // return '*/*'
    }

    if (isset($options['fallback_format'])) {
        // if false === fallback_format then we fail here instead of considering more rules
        if (false === $options['fallback_format']) {
           return null;
        }

        // stop looking at rules since we have a fallback defined
        return $request->getMimeType($options['fallback_format']);
    }

    // ...

Before, the format variable was null and the format was taken on the fallback_format:

// FOS\RestBundle\Util\FormatNegotiator

/**
 * Detect the request format based on the priorities and the Accept header
 *
 * @param   Request         $request          The request
 * @return  void|string                       The format string
 */
public function getBestMediaType(Request $request)
{
    // ...

    $format = $this->formatNegotiator->getBestFormat($acceptHeader, $options['priorities']);
    if (null !== $format) {
        return $format;
    }

    if (isset($options['fallback_format'])) {
        // if false === fallback_format then we fail here instead of considering more rules
        if (false === $options['fallback_format']) {
           return null;
        }

        // stop looking at rules since we have a fallback defined
        return $request->getMimeType($options['fallback_format']);
    }

    // ...

So, I think I should be stricter and set my Accept header.

[lsmith77]

Ah I see .. I need to check this out as it might be an unwanted regression.

[phiamo]

shit should have looked here before :-)
having the same, there seems not to be any fallback for sending

Accept: */*

headers.

My config is:

fos_rest:
    ...
    format_listener:
        rules:
            - { path: '^/api', priorities: ['json', 'html'], fallback_format: html, prefer_extension: true }
            - { path: '^/', priorities: [ 'html', '*/*'], fallback_format: ~, prefer_extension: true }
    ...

in https://github.com/liip-forks/symfony-standard/blob/techtalk/app/config/config.yml the last line does not contain

'*/*' 

does the techtalk sandbox not support _wdt cause this is issueing the request:

or is there any other way implemented i didnt see (.htaccess does not change the request in that way or?)

[phiamo]

btw this is probably the same as the error i am having now for fosrouting request:
