使用Silex框架开发restapi

Question

我开始使用 silex 来休息 api。这是我的第一个 api!

我做了什么：

更新： Federic 的提示改进了代码。添加使用 Symfony JsonResponse。暂时不工作。

<?php
require_once __DIR__.'/vendor/autoload.php';

use Symfony\Component\HttpFoundation\JsonResponse;

// init Silex app
$app = new Silex\Application();
$app['debug'] = true;

//configure database connection
$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
    'db.options' => array(
        'driver' => 'pdo_mysql',
        'host' => '127.0.0.1',
        'dbname' => 'db',
        'user' => 'root',
        'password' => '',
        'charset' => 'utf8',
    ),
));

$app->get('/apps', function () use ($app){
    $sql = "select apps.id, apps.guid, apps.title, clients.client, countries.country, langs.lang, apps.active from apps
            inner join countries on apps.id_country = countries.id
            inner join clients on clients.id = apps.id_client
            inner join langs on langs.id = apps.id_lang
            order by apps.created_at desc";
    $results = $app['db']->fetchAll($sql);


        $response['status'] = array(
            'code' => 200,
            'message' => 'OK'
        );

        $response['data'] = $results;

    //return $app->json($response);
    $jsonResponse = new JsonResponse($response);
    $jsonResponse->setEncodingOptions(JsonReponse::DEFAULT_ENCODING_OPTIONS | JSON_PRETTY_PRINT);

    return $jsonResponse;
});


$app->run();

什么return？

{"status":{"code":200,"message":"OK"},"data":[{"id":"2","guid":"a8559e9b-d850-4964-b672-335a87fe9e8b","title":"Coverdine Plus Light","client":"Servier","country":"England","lang":"English","active":"1"},{"id":"1","guid":"4f242e9d-c041-4c79-bc82-b62604de403c","title":"Coverdine","client":"Servier","country":"England","lang":"English","active":"0"}]}

我如何使用 JSON_PRETTY_PRINT 来改进我的 json 对象的人类阅读？

Answer 1

不使用 $app->json($response);，而是使用 JsonResponse。你可以用他的setEncodingOptions方法设置JSON_PRETTY_PRINT标志。

<?php
use Symfony\Component\HttpFoundation\JsonResponse;

// ...
$jsonResponse = new JsonResponse($response);
$jsonResponse->setEncodingOptions(JsonResponse::DEFAULT_ENCODING_OPTIONS | JSON_PRETTY_PRINT);

return $jsonResponse;

Answer 2

我也遇到过这个困难，经过大量研究我找到了功能：do_dump，click here在github中看到它。

要使用它，只需这样做：



$var = json_decode('{"a":1,"b":2,"c":3,"d":4,"e":5}');
do_dump($var);

Answer 3

这对我有用：

...
require_once(__DIR__ .'/../vendor/autoload.php');
use Symfony\Component\HttpFoundation\Response;

...
$response = $sth->fetchALL(PDO::FETCH_ASSOC);
return $app->json($response, Response::HTTP_OK)->setEncodingOptions(JSON_PRETTY_PRINT);
