Slim 2.6.2 render() 仅适用于 Index.html
Slim 2.6.2 render() Only Works for Index.html
我目前正在 TeamTreehouse.com 学习 Slim 框架，运行 遇到一个我无法解决的问题。
在项目的这一点上，我们已经通过 Composer 安装了 Slim，并在我们的文档根目录（在我的计算机上是 /home/daniel/src/public_html/treehouse/build_websites_php/）中设置了 .htaccess 和 index.php 文件。
在模板文件夹中，我们有 index.html 和 contact.html。这是文件夹的布局。
- 文档根目录 (/home/daniel/src/public_html/treehouse/build_websites_php/)
- index.php
- .htaccess
- composer.json
- composer.lock
- 供应商/
- 模板/
- index.html
- contact.html
在index.php中，我实例化了一个新的Slim对象：
$app = new \Slim\Slim();
然后在url为localhost/treehouse/build_websites/和localhost/treehouse/build_websites/联系人，分别为。
$app->get('/', function () use($app) {
$app->render('index.html');
});
$app->get('/contact', function () use($app) {
$app->render('contact.html');
});
然后 运行 应用：
$app->run();
我的 index.html 页面显示正常，但是当我尝试访问 /contact url 时出现 404 错误（不是通过 Slim，只是服务器的默认错误）。以下是我的系统的一些规格：
- Ubuntu 16.04.1 LTS
- 阿帕奇 2.4.18
- 纤薄 2.6.2
- PHP7.0.8
我的 /home/daniel/src/public_html/ 目录中的任何内容都可以通过 Apache 访问，因为我在过去的一年里从那里 运行 PHP 脚本。
我已经尝试了 here 的建议（并在每次更新到 conf.d 或其他文件后重新启动服务器）但没有成功。
任何帮助将不胜感激，我只使用 PHP/Ubuntu/Apache 大约一年，所以我可能遗漏了一些明显的东西！
这里是 index.php 文件：
<?php
require 'vendor/autoload.php';
$app = new \Slim\Slim();
$app->get('/', function () use($app) {
/* When using render(), the url localhost/treehouse/build_websites_php/ to
gets you the home page. */
$app->render('index.html');
});
/* This SHOULD bring up the contact page at url
localhost/treehouse/build_websites_php/contact, but it doesn't! */
$app->get('/contact', function () use($app) {
$app->render('contact.html');
});
$app->run();
?>
这里是 .htacess 文件：
RewriteEngine On
# Some hosts may require you to use the `RewriteBase` directive.
# If you need to use the `RewriteBase` directive, it should be the
# absolute physical path to the directory that contains this htaccess file.
#
# RewriteBase /home/daniel/src/public_html/treehouse/build_websites_php/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]
下面是 Apache 的各种 conf.d 文件：
/etc/apache2/apache2.conf
# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.
<Directory />
Options FollowSymLinks
AllowOverride None
Require all denied
</Directory>
<Directory /usr/share>
AllowOverride None
Require all granted
</Directory>
<Directory /home/daniel/src/public_html>
Order allow,deny
Allow from all
Require all granted
</Directory>
我尝试按照建议 here 将 AllowOverride All 添加到最后一条指令，然后我根本无法从服务器访问 PHP 文件，并收到 500 错误而不是 404错误。
/etc/apache2/sites-available/000-default.conf

# value is not decisive as it is used as a last resort host regardless.

您的 Apache 设置似乎不允许 .htaccess 文件覆盖任何设置。在 apache2.conf.
中添加如下内容
<Directory /home/daniel/src/public_html>
AllowOverride All
Order allow,deny
Allow from all
Require all granted
</Directory>
好的哇，感谢 Mika 为我指明了正确的方向，我终于弄明白了。事实证明，我的 /etc/apache2/sites-available/mysite.conf 文件需要以下指令：
<Directory /home/daniel/src/public_html >
AllowOverride All
</Directory>
除了像这样的其他指令之外，我还尝试将该指令添加到 /etc/apache2/apache2.conf：
<Directory />
Options FollowSymLinks
AllowOverride None
Require all denied
</Directory>
<Directory /usr/share>
AllowOverride None
Require all granted
</Directory>
<Directory /home/daniel/src/public_html>
Order allow,deny
Allow from all
Require all granted
AllowOverride All #THIS DIDN'T WORK
</Directory>
但是上面的 AllowOverride All 通过来自服务器的 500 错误。显然，它必须单独存在于 /etc/apache2/sites-available/mysite.conf 文件中，谁知道呢！
我还 运行 sudo a2enmod rewrite && sudo /etc/init.d/apache2 restart 以确保 mod_rewrite 在发现此错误消息后已加载（感谢 Mika 指出检查日志文件！）：
[Sun Nov 13 10:37:51.054347 2016] [core:alert] [pid 10979] [client ::1:51900] /home/daniel/src/public_html /treehouse/build_websites_php/.htaccess: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
我在添加 AllowOverride All 指令之前这样做了，所以我不确定它是否在解决问题中发挥了作用，但我想我会记录它以供感兴趣的人使用。
这些站点提供了有关如何最终解决问题的宝贵信息：
- 1 - solved mod_rewrite issue
- 2 - solved where to place the AllowOverride All directive
