Slim\Exception\HttpNotFoundException

我正在创建一个新的 Slim 项目并收到以下错误： 苗条应用程序错误： 由于以下错误，应用程序无法运行：

错误详情

Type: Slim\Exception\HttpNotFoundException
Code: 404
Message: Not found.

这是我的index.php

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

require '../vendor/autoload.php';

$app = AppFactory::create();
$app->addRoutingMiddleware();
$errorMiddleware = $app->addErrorMiddleware(true, true, true);

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

$app->run();

这可能是一个基本问题。但我是新人。需要帮助。

为了解决 Slim 4 的问题，我这样做了：

1/ 就在之后

$app = AppFactory::create();

我补充道：

$app->setBasePath("/myapp/api"); // /myapp/api is the api folder (http://domain/myapp/api)

2/在我的.htaccess中：

RewriteEngine on  
RewriteCond %{ENV:REDIRECT_STATUS} !200 
RewriteRule ^api/(.*)$ api/index.php/$1

3/最后为了处理“HttpNotFoundException”Slim异常，我添加了一个try/catch（我不知道为什么Slim不内部处理它=>也许是为了给我们更多的可能性？）

try {
    $app->run();     
} catch (Exception $e) {    
  // We display a error message
  die( json_encode(array("status" => "failed", "message" => "This action is not allowed"))); 
}

希望它能有所帮助

** 编辑 => 强制 Slim 处理异常，之后：**

$app = AppFactory::create();

add :

$app->addErrorMiddleware(true, true, true);
