url 路由在 CodeIgniter 4 中拋出 400 Bad Request 錯誤

Question

在無數次其他網友的幫助下，我終於要問我的第一個問題了。

我想做什么：
在實時服務器上運行 CodeIgniter 項目（版本 4.2.8）。

問題：
URL 路由不工作（400 錯誤請求錯誤）。 這是全新安裝，因此除了默認的 CodeIgniter 主頁（上面寫着“歡迎使用 CodeIgniter”的那個）之外沒有其他頁面。

當我這樣訪問它時，歡迎頁面正確顯示：

www.example.com
www.example.com/index.php

我在嘗試時收到 Bad Request 錯誤：

www.example.com/home

這是我所做的：

服務器上的文件夾結構：

root
 |
 +  | dir public_html
 |  |  
    +  | dir www.example.com //web root, this is where I put the files that were in the CI public folder
    +  | dir exampleCI4 //here I put all the other CI files and folders app, vendor, writable...

我調整了以下文件：

• 例子CI4/app/Config/App.php

public $baseURL = 'http://www.example.com'

• www.example.com/index.php

// Load our paths config file
// This is the line that might need to be changed, depending on your folder structure.
require FCPATH . '../exampleCI4/app/Config/Paths.php';
// ^^^ Change this line if you move your application folder

起初我總是收到 500 Internal Server 錯誤。 經過數小時的尋找解決方案后，我發現了這篇文章：

CodeIgniter4.htaccess 不適用於 Options All -Indexes

這確實解決了 500 Internal Server 錯誤，歡迎頁面正在顯示。 我還與我的托管服務提供商確認過，事實證明他們不允許 Options All 和 FollowSymlinks。

我很確定 .htaccess 文件中有一些東西需要調整，但我不知道是什么。

這是完整的.htaccess 文件：

• public_html/www.example.com/.htaccess

#Disable directory browsing
 Options -Indexes

# ----------------------------------------------------------------------
# Rewrite engine
# ----------------------------------------------------------------------

# Turning on the rewrite engine is necessary for the following rules and features.
# FollowSymLinks must be enabled for this to work.
<IfModule mod_rewrite.c>
    # Options +FollowSymlinks
    Options +SymLinksIfOwnerMatch
    RewriteEngine On

    # If you installed CodeIgniter in a subfolder, you will need to
    # change the following line to match the subfolder you need.
    # http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritebase
    # RewriteBase /

    # Redirect Trailing Slashes...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Rewrite "www.example.com -> example.com"
    RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
    RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

    # Checks to see if the user is attempting to access a valid file,
    # such as an image or css document, if this isn't true it sends the
    # request to the front controller, index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^([\s\S]*)$ ../index.php/$1 [L,NC,QSA]

    # Ensure Authorization header is passed along
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    ErrorDocument 404 index.php
</IfModule>

# Disable server signature start
    ServerSignature Off
# Disable server signature end

如果有人能告訴我需要更改哪些內容才能使其正常工作，那就太棒了。

Answer 1

讓它運行。

原來我忘記在 spark 文件中進行必要的調整。

在這里更改了這部分：

    /*
 *---------------------------------------------------------------
 * BOOTSTRAP THE APPLICATION
 *---------------------------------------------------------------
 * This process sets up the path constants, loads and registers
 * our autoloader, along with Composer's, loads our constants
 * and fires up an environment-specific bootstrapping.
 */

// Load our paths config file
// This is the line that might need to be changed, depending on your folder structure.
require FCPATH . 'app/Config/Paths.php';
// ^^^ Change this line if you move your application folder

你能在配置文件中試試這個嗎？ 將基數 URL 設置為：

$base_url = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$base_url .= "://". @$_SERVER['HTTP_HOST'];
$base_url .=     str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
$config['base_url'] = $base_url;
