php - Can't Http Delete Method on Simple PHP API using Silex - 超出子请求限制
问题描述
我试图通过编写一个简单的购物清单应用程序来掌握 PHP 和 REST。目前，我可以 GET 和 POST 到 API，但是，每次我尝试运行 DELETE 方法时，我的 apache 日志中都会出现 500 Internal Server 错误和以下内容：

这是我的 index.php 的样子：
<?php
require 'vendor/autoload.php';
include 'bootstrap.php';
use smart_shopper_api\Models\ShoppingListItem;
use smart_shopper_api\Middleware\Logging as ApiLogging;
use Symfony\Component\HttpFoundation\Request as Request;
use Symfony\Component\HttpFoundation\Response as Response;
$app = new Silex\Application();
// never use in production
$app['debug'] = true;
ini_set('display_errors', 'On');
error_reporting(E_ALL);
$app->before(function($request, $app) {
ApiLogging::log($request, $app);
});
$app->get('/shopping-list', function () use ($app) {
$_shoppingList = new ShoppingListItem();
$shoppingListItems = $_shoppingList->all();
$payload = [];
foreach ($shoppingListItems as $_item) {
$payload[$_item->id] = [
'name' => $_item->name,
'description' => $_item->description,
'price' => $_item->price,
'created_at' => $_item->created_at,
'updated_at' => $_item->updated_at
];
}
return $app->json($payload, 200);
});
$app->post('/shopping-list', function(Request $request) use($app) {
$_name = $request->get('name');
$_description = $request->get('description');
$_price = $request->get('price');
$shoppingListItem = new ShoppingListItem();
$shoppingListItem->name = $_name;
$shoppingListItem->description = $_description;
$shoppingListItem->price = $_price;
$shoppingListItem->save();
if($shoppingListItem->id) {
$code = 201;
$payload = [
'id' => $shoppingListItem->id
];
} else {
$code = 400;
$payload = [];
}
return $app->json($payload, $code);
});
$app->delete('/shopping-list/{item_id}', function($item_id) use($app) {
$shoppingListItem = ShoppingListItem::where('id', $item_id);
if($shoppingListItem != null) {
$shoppingListItem->delete();
} else {
return new Response('Shopping List Item not found. It may be deleted before or it may have never existed.', 200);
}
if($shoppingListItem->exists) {
return new Response('', 400);
} else {
return new Response('', 204);
}
});
$app->get('/test', function () use ($app) {
return "This route confirms that Silex is running. This doesn't contain a call to the Database However.";
});
$app->run();
我做了一些研究“AH00125：由于可能的配置错误，请求超出了 10 个子请求嵌套级别的限制。如有必要，请使用 'LimitInternalRecursion' 来增加限制。使用 'LogLevel debug' 来获取回溯。” 意思是，我能够将内部递归更改为 1000，但是它创建了 1000 个条目，所以有些东西在循环，我无法指望。
这是我的虚拟主机配置：
<VirtualHost *:443>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
SSLEngine On
SSLCertificateFile /etc/ssl/apache2/smart-shopper/cert.pem
SSLCertificateKeyFile /etc/ssl/apache2/smart-shopper/key.pem
ServerName smart-shopper.example.com
ServerAdmin webmaster@localhost
Alias /smart-shopper-api/ /var/www/html/smart-shopper/smart-shopper-api/
<Directory "/var/www/html/smart-shopper/smart-shopper-api/">
FallbackResource index.php
</Directory>
DocumentRoot /var/www/html/smart-shopper/smart-shopper-api/
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/smart-shopper-error.log
CustomLog ${APACHE_LOG_DIR}/smart-shopper-access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
任何帮助将不胜感激。
解决方案
好的，我无法在 Apache 中对此进行排序，因此我更改了 Web 服务器软件。
在 Web 服务器在 Ubuntu Server 18.04 上运行 Apache2 之前，我已将其更改为 nginx。这是我的 Nginx 虚拟主机配置对于可能遇到相同问题的任何人的外观：
server {
listen 443 ssl default_server;
ssl_certificate /etc/ssl/nginx/certs/cert.crt;
ssl_certificate_key /etc/ssl/nginx/certs/key.key;
#listen [::]:80 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;
root /var/www/html/smart-shopper/smart-shopper-api;
# Add index.php to the list if you are using PHP
index index.php index.html index.htm index.nginx-debian.html;
server_name mywebsite.com;
if (!-e $request_filename)
{
rewrite ^/(.*)$ /index.php?/$1 last;
break;
}
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
#try_files $uri $uri/ =404;
try_files $uri /index.php$is_args$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}
location ~ /\.ht {
deny all;
}
# pass PHP scripts to FastCGI server
#
#location ~ \.php$ {
# include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
所以它现在正在工作，这是主要的事情。现在我将 Nginx 用于一切，因为我无法在 Apache 中解决这个问题。所以 bazaar 你不能运行 DELETE 方法来重写 index.php。也许有人可能知道答案，但目前这是最好的方法。
