An HTTP requests mock generator symfony bundle.

This bundle allows to log HTTP requests and associated responses as json files. This generated json files can be used as API mock in order to test a front app without running the api.

After each request (Kernel::TERMINATE event) containing the x-generate-response-mock header, a json file is created containing the request and the response.

Examples :

GET /categories

app/log/mocks/categories/GET__.json

{
    "request": {
        "uri": "/categories",
        "method": "GET",
        "parameters": [],
        "content": ""
    },
    "response": {
        "statusCode": 200,
        "contentType": "application/json",
        "content": {
            "@context": "/contexts/Category",
            "@id": "/categories",
            "hydra:member": [
                {"name": "foo"},
                {"name": "bar"}
            ]
        }
    }
}

PUT /categories/1 {"foo": "bar"}

app/log/mocks/categories/PUT__1-a5e74.json

{
    "request": {
        "uri": "/categories/1",
        "method": "PUT",
        "parameters": [],
        "content": {
            "foo": "bar"
        }
    },
    "response": {
        "statusCode": 204,
        "contentType": "application/json",
        "content": ""
    }
}

File naming strategy

All files are created with the following convention :

uri/METHOD__segments{--sorted-query=string&others}{__<sha1_substr5(sortedJsonContent)>}{__<sha1_substr5(sortedPostParameters)>}.json

Examples :

The filenames query strings can be hashed by setting the `hash_query_params` option to `true`.
For example, `categories/GET__--order[bar]=desc&order[foo]=asc.json` will be `categories/GET__--b0324.json`

The filenames query strings with non-asssocitive arrays are not indexed by default : `?foo[]=bar`.
You can use the indexed format by setting the `use_indexed_associative_array` option to `true` : `?foo[0]=bar`.

See the ResponseLoggerTest file for more examples.

You can use Composer to install the bundle to your project as a dev dependency :

composer require --dev mroca/request-log-bundle

Then, enable the bundle by updating your app/config/AppKernel.php file to enable the bundle:

<?php
// app/config/AppKernel.php

public function registerBundles()
{
    //...
    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Mroca\RequestLogBundle\RequestLogBundle();
    }

    return $bundles;
}

If necessary, configure the bundle to your needs (example with default values):

# app/config/config_dev.yml

mroca_request_log:
    mocks_dir: %kernel.logs_dir%/mocks/
    hash_query_params: false
    use_indexed_associative_array: false

If your are using the NelmioCorsBundle or another CORS protection, you must add the header in the allowed ones :

nelmio_cors:
    defaults:
        allow_headers: ['x-generate-response-mock']

The request & response logger is not always activated. To log a request, add the x-generate-response-mock header into your request :

GET /categories HTTP/1.1
Host: api.my.domain
x-generate-response-mock: true

Some useful commands are available to manager your mocks :

app/console mroca:request-log:clear 

app/console mroca:request-log:dump /tmp/mocksdirtarget
