php - Slim Framework always return 404 Error

Question

These days i'm using Slim Framework as my simplest tool to develop the php web api. Using these two articles:

I follow some of the steps from there. Downloading the Slim Framework, putting the correct directory & files. Adjusting the initation statements such as;

//1. Require Slim
require('Slim/Slim.php');

//2. Instantiate Slim
$app = new Slim();

//3. Define routes
$app->get('/books', function ($id) {
    //Show book with id = $id
});

And then, I modify the rest accordingly.

Such as my checklist that already done:

LoadModule rewrite_module modules/mod_rewrite.so -> enabled
Slim .htaccess:

RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ bootstrap.php [QSA,L]

httpd.conf: (Shared Link).

But, after Once I run this statement;

$app->run();

And I run it on my browser.... then, I got 404 Error while testing it on my Localhost. What's the solution for fixing that?

FYI, here is my simplest PHP file that i'm currently using it. (shared Link)

Problem is solved!

My apache is actually normal, and the .htaccess file provided earlier also normal.

The clue is the URL that I used. Previously I used the invalid URL, thus it returned the 404 page error. I just realized it when I Tried to access the newer GET URL via browser with this one;

http://localhost/dev/index.php/getUsers/user1

and now that works!

I just realized it once I found these statements;

If Slim does not find routes with URIs that match the HTTP request URI, Slim will automatically return a 404 Not Found response.

If Slim finds routes with URIs that match the HTTP request URI but not the HTTP request method, Slim will automatically return a 405 Method Not Allowed response with an Allow: header whose value lists HTTP methods that are acceptable for the requested resource.

我在谷歌搜索“slimframework 404”时发现了这篇文章。该帖子使我找到了解决问题的方法。

问题

我使用Composer使用 Slim 框架建立了一个站点，并使用以下示例代码 form slimframework.com 创建了一个 index.php：

<?php
$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
    echo "Hello, $name";
});
$app->run();

然后我尝试使用http://localhost/hello/bob. 我返回一个 404 Page Not Found 页面。

我能够使用http://localhost/index.php/hello/bob.

解决方案

我通过查看/vendor/slim/.htaccess（包括 Composer Slim 安装）和 Slim 框架文档的URL 重写部分找到了解决方案。

我将该文件的副本添加/vendor/slim/.htaccess到与我的 index.php 文件相同的文件夹中。该文件的内容是：

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]

现在我可以使用http://localhost/hello/bob.

您将 index.php 包含在您的文件中是正确的，但这是因为您无法正常使用 mod-rewrite 请检查以下链接：

在入门部分，您可以看到如何配置您的服务器（如果您使用的是 apache / lighttpd / ngynx）

我认为您的问题出在“资源解析器”上，因为您没有在请求中定义 $id 参数，所以请尝试以下操作：

//1. Require Slim
require('Slim/Slim.php');

//2. Instantiate Slim
$app = new Slim();

//3. Define routes
$app->get('/books/:id/', function ($id) {
    echo json_encode( getBook($id) );
});

// some stuff
$app->run();

请告诉我们是否可以

对我来说，问题是我忘记.htaccess在我的文档根目录中提供一个文件。

.htaccess

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php [L]

此外mod_rewrite.so，必须加载模块，httpd.conf否则您将收到错误 500。

LoadModule rewrite_module modules/mod_rewrite.so

如果您在 Ubuntu 16.04 上使用 Slim 并且收到 404 错误。试试上面 Tod Birdsall 的这个测试：

如果这有效

http://localhost/index.php/hello/bob

这不起作用

http://localhost/hello/bob

和您的 .htaccess 文件在与您的 index.php 相同的目录中，配置如下：

    <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^ index.php [QSA,L]
    </IfModule>

而且您仍然会在 Apache 上收到 404 错误。

尝试如下开启 Apache mod_rewrite 并重启 Apache：

$sudo a2enmod 重写

$sudo 服务 apache2 重启

Slim API 现在应该可以正常工作了，因为提供的 .htaccess 文件只有在 mod_rewrite 启用并且不是全新安装的默认设置时才能工作。

如果需要，这是关闭 mod_rewirte 的方法。

$sudo a2dismod 重写

$sudo 服务 apache2 重启

对于因为以前不起作用而仍在搜索答案的人，这对我有用：

RewriteBase /<base_of_your_project>/
