[slimPHP](Ver3)の基本的ルートの設定

基本設定

〇〇.php

<?php
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
require "vendor/autoload.php";
use \Slim\App;

$configuration = [
    'displayErrorDetails' => true //エラーの情報をえるか？　開発は欲しいのでtrue 本番はエラーをユーザーに表示するのは危険なのでfalse
];

$app = new \Slim\App($configuration);

/*
以下記述はここにかく
*/

$app->run();

指定パスのみ

〇〇.php

//methoがGETでPassがhelloの場合
$app->get('/hello', function (ServerRequestInterface $request, ResponseInterface  $response, $args = []) {
    $response->getBody()->write("Hello");
    return $response;
});

//methoがPOSTでPassがhelloの場合
$app->post('/hello', function (ServerRequestInterface $request, ResponseInterface  $response, $args = []) {
    $response->getBody()->write("Hello");
    return $response;
});

出力:

指定パス+任意パス

〇〇.php

$app->get('/hello/{name}', function (ServerRequestInterface $request, ResponseInterface  $response, $args = []) {
    $name = $args['name'];
    $response->getBody()->write("Hello, $name");
    return $response;
});

出力:

指定パス+任意パス(正規表現)

〇〇.php

$app->get('/user/{id:[0-9]+}', function (ServerRequestInterface $request, ResponseInterface  $response, $args = []) {
    $id = $args['id'];
    $response->getBody()->write("$id, のUserさん");
    return $response;
});

出力:

指定パス+任意パス達(あってもなくても通る)

〇〇.php

$app->get('/news[/{year}[/{month}]]', function ($request, $response, $args) {
    $year = $args['year'] ?: 'year';
    $month = $args['month'] ?: 'month';
    $response->getBody()->write("本日のNews, $year, $month");
    return $response;
});

出力:

クエリ取得

〇〇.php

$app->get('/samples', function (ServerRequestInterface $request, ResponseInterface $response,  $res, $args = []) {
    return '!' . implode( $request->getQueryParams());
});

出力:

※単一で取得したい場合
$myvar = $request->getQueryParams()["myvar"]; //Get 取得

※postで取得したい場合
$request->getParsedBody()

ヘッダー取得

〇〇.php

$app->get('/samples', function (ServerRequestInterface $request, ResponseInterface $response,  $res, $args = []) {
    $headers = $request->getHeaders();
    foreach ($headers as $name => $values) {
        echo $name . ": " . implode(", ", $values);
    }
    return '!';
});

出力:

複数method対応

〇〇.php

app->map(['GET', 'POST'], '/book', function ($request, $response, $args) {
  $response->getBody()->write("book!!");
  return $response;
});

※methos取得したい場合(文字列)
$method = $request->getMethod();

出力方法(JSONで)

〇〇.php

$app->get('/samplesample', function ($request, $response, $args) {
    $data = array('name' => 'Bob', 'age' => 40);
    $newResponse = $response->withJson($data);
    return $newResponse;
});

出力:

出力方法(HTMLタグ使用)

〇〇.php

$app->get('/samplesample', function ($request, $response, $args) {
    $url = 'https://www.php.net';
    $response->write("<a href='$url'>PHPページに飛びます</a>");
    return $response;
});

出力:

group作成

〇〇.php

$app->group('/users/{id:[0-9]+}', function () {
    $this->group('/auth', function () {
        $this->map(['GET', 'POST'], '/books', function ($request, $response, $args) {
            return $response->write("ppppp-");
        });
    });

    $this->group('/a', function () {
        $this->map(['GET', 'POST'], '/books', function ($request, $response, $args) {
            return $response->write("ppppp1");
        });
    });
});
