Features and Usage

(Only works for REST endpoints.)

This module is designed as a dependency for developing other modules.

1. Support for Content-Type: application/x-www-form-urlencoded
Magento WEBAPI_REST recognizes application/json, application/xml, application/xhtml+xml, text/xml Content-Type out of the box, any others will result in an error message like "message": "Server cannot understand Content-Type HTTP header media type application/x-www-form-urlencoded"

However, application/x-www-form-urlencoded is commonly used in forms and many third part software could only POST this content type.

How to use?
Just make the request normally using Content-Type: application/x-www-form-urlencoded and add an additional custom header Use-Deprecated-Content-Type: 1.
Note: You MUST include the Use-Deprecated-Content-Type: 1 header in your request, otherwise it does not work!

2. Conditionally modifies JSON output behavior
When developing a service class(usually a file called someActionManagement.php in Model folder), if it returns an array like below,

return [
    'code' => 0,
    'message' => 'Success',
    'data' => [
        'customer_id' => 1
    ]
];

Magento encloses the returned data in an array parentheses and property names got stripped out.
Output:

[
    0,
    "Success",
    {
        "customer_id": 1
    }
]

This may be not what you want.
If the service class returns

return [
    'dummy' => [
        'code' => 0,
        'message' => 'Success',
        'data' => [
            'customer_id' => 1
        ]
    ]
];

the output becomes

[
    {
        "code": 0,
        "message": "Success",
        "data": {
            "customer_id": 1
        }
    }
]

Note the outermost [], many third party software expects the output to be an object, though.

How to use?
Add 'type' => 'simple_array' in the output array, i.e.,

return [
    'code' => 0,
    'message' => 'Success',
    'data' => [
        'customer_id' => 1
    ],
    'type' => 'simple_array' // Add this key-value pair
];

Then output will be

{
    "code": 0,
    "message": "Success",
    "data": {
        "customer_id": 1
    }
}

Note: the JSON output will not have "type": "simple_array", it got removed!
