Swagger is not working in integration with ZendFramework2

Question

Could you please suggest why Swagger is not working for me in integration with ZendFramework2. I followed the instructions given here .

composer.json :

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.5",
        "outeredge/swagger-module": "dev-master"
    },
}

config/application.config.php :

<?php
    return array(
        'modules' => array(
            'MyApp',
            'SwaggerModule',
        ),
        'module_listener_options' => array(
            'module_paths' => array(
                './module',
                './vendor',
            ),
        ),
    );
?>

/config/autoload/swagger.global.php :

return array(
    'swagger' => array(
        'paths' => array(
            __DIR__ . '/../../module/Morpho/src/Morpho/Controller',
        ),
        'resource_options' => array(
            'output' => 'array',
            'json_pretty_print' => true, // for outputtype 'json'
            'defaultBasePath' => null,
            'defaultApiVersion' => null,
            'defaultSwaggerVersion' => '1.2',
        ),
    )
);

After I deploy the application under Apache, when call http://myapp/public/api/docs , I get:

{"errors":[{"message":"An error occurred during execution;
please try again later.","error":"error-exception","exception":
"class":"Zend\ServiceManager\Exception\ServiceNotCreatedException",
"file":"\vendor\zendframework\zendframework\library\Zend\ServiceManager\ServiceManager.php",
"line":930,
"message":"An exception was raised while creating "Swagger\Swagger";

Answer 1

swagger-module seems not active. Please try https://github.com/zircote/swagger-php instead.

Answer 2

I was getting same type of error and able to fix the issue by following.

Create file in in Development system swagger.development.php 在创建文件在开发系统中为swagger.development.php

have following content. 具有以下内容。

return array(
    'swagger' => array(
        'paths' => array(
            __DIR__ . '/../../module/Api/src/Api/Controller',
        ),
        'resource_options' => array(
            'output' => 'array',
            'json_pretty_print' => true, 
            'defaultBasePath' => '/',
            'defaultApiVersion' => null,
            'defaultSwaggerVersion' => '1.2',
        ),
    )
);
