在服务器上上传 php CodeIgniter 文件时出现错误 404答案

【问题标题】：Error 404 when uploading php CodeIgniter files on server在服务器上上传 php CodeIgniter 文件时出现错误 404

【问题描述】：

我已经在生产环境中上传了我在框架 CodeIgniter 上制作的 PHP 网站文件。尽管我更改了 .htaccess 文件及其依赖项（配置等），但仍然出现错误 404，就好像服务器无法访问控制器文件一样。这是我第一次尝试将网站投入生产，有什么想法吗？

.htaccess

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

### Canonicalize codeigniter URLs

# If your default controller is something other than
# "welcome" you should probably change this
RewriteRule ^(welcome(/index)?|index(\.php)?)/?$ / [L,R=301]
RewriteRule ^(.*)/index/?$ $1 [L,R=301]

# Removes trailing slashes (prevents SEO duplicate content issues)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [L,R=301]

# Enforce www
# If you have subdomains, you can add them to 
# the list using the "|" (OR) regex operator
RewriteCond %{HTTP_HOST} !^(www|subdomain) [NC]
RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]

# Enforce NO www
#RewriteCond %{HTTP_HOST} ^www [NC]
#RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]

###

# Removes access to the system folder by users.
# Additionally this will allow you to create a System.php controller,
# previously this would not have been possible.
# 'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [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 index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

# Without mod_rewrite, route 404's to the front controller
ErrorDocument 404 /index.php

config.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

$config['base_url'] = 'http://mywebsite.com';
$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'REQUEST_URI';
$config['url_suffix'] = '';

【问题讨论】：

请提供有关问题的更多详细信息。例如您的代码和您尝试上传到的路径。
请提供一些代码和你的路径。这将有助于我们帮助您。
服务器上的 mod_rewrite 是否处于活动状态？如果是，请确保 .htaccess 文件具有 Options -Multiviews +FollowSymlinks 指令，并且您可以覆盖选项。

【解决方案1】：

您是否配置了 base_url() 函数？它在 config.php 文件中。如果它是空的，它假定你正在使用本地主机，所以你必须把你的域放在那里。

转到 config.php 并找到这一行：

$config['base_url'] = '';

把你的域名放在那里。

$config['base_url'] = 'http://YOURDOMAINHERE.com';
