在Laravel 5.5中，在根目录中创建。htess文件，并放置以下代码

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ ^$1 [N]

    RewriteCond %{REQUEST_URI} (\.\w+$) [NC]
    RewriteRule ^(.*)$ public/$1 

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ server.php

</IfModule>

我使用的另一种方法是在htdocs或www中使用ln命令创建一个符号链接(在Linux中，不知道Win)，即ln projectname/public project 因此，站点可以通过localhost/project访问

1)我还没有找到L5中公共目录移动的工作方法。虽然可以修改bootstrap index.php中的一些内容，但似乎有几个辅助函数是基于公共目录存在的假设。总之，老实说，你真的不应该移动公共目录。

2)如果你使用MAMP，那么你应该为每个项目创建新的vhosts，每个服务于项目的公共目录。创建后，您可以通过定义的服务器名访问每个项目，如下所示:

http://project1.dev
http://project2.dev

请将这些行添加到您的根.htaccess文件中，它隐藏了/public并重定向到所有没有public的url

RewriteEngine on
RewriteCond %{REQUEST_URI} !public/
RewriteRule (.*) /public/$1 [L]

与Laravel 5.5相关：

在第一次安装Laravel后，我遇到了著名的“公共文件夹问题”，我想出了这个解决方案，在我个人看来，它比我在网上找到的其他解决方案更“干净”。

成就

URI中没有公共词 保护.env文件，防止好奇的人

只要使用mod_rewrite和四个简单的规则编辑.htaccess，一切都可以完成。

步骤

移动.htaccess文件到public/。Htaccess在主根目录下 编辑如下

I commented everything, so it should be clear (I hope) also to those who have never used mod_rewrite (not that I'm an expert, all the opposite). Also, to understand the rules, it must be clear that, in Laravel, if Bill connects to https://example.com, https://example.com/index.php is loaded. This file just contains the command header("refresh: 5; https://example.com/public/"), which sends the request to https://example.com/public/index.php. This second index.php is responsible to load the controller and other stuff.

# IfModule prevents the server error if the app is moved in an environment which doesn’t support mod_rewrite
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # RULES ORIGINALLY IN public/.htaccess ---
    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Handle Front Controller...
#    RewriteCond %{REQUEST_FILENAME} !-d
#    RewriteCond %{REQUEST_FILENAME} !-f
#    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    # --- END

    # PERSONAL RULES ---
    # All the requests on port 80 are redirected on HTTPS
    RewriteCond %{SERVER_PORT} ^80$
    RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

    # When .env file is requested, server redirects to 404
    RewriteRule ^\.env$ - [R=404,L,NC]

    # If the REQUEST_URI is empty (means: http://example.com), it loads /public/index.php
    # N.B.: REQUEST_URI is *never* actually empty, it contains a slash that must be set as match as below
    # .* means: anything can go here at least 0 times (= accepts any sequence of characters, including an empty string)
    RewriteCond %{REQUEST_URI} ^/$
    RewriteRule ^(.*) /public/index.php [L]

    # If the current request is asking for a REQUEST_FILENAME that:
    # a) !== existent directory
    # b) !== existent file
    # => if URI !== css||js||images/whatever => server loads /public/index.php, which is responsible to load the app and the related controller
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule !^(css|js|images|media)/(.*)$ /public/index.php [L,NC]

    # If the current request is asking for a REQUEST_FILENAME that:
    # a) !== existent directory
    # b) !== existent file
    # => if URI == css||js||images[=$1]/whatever[=$2] => server loads the resource at public/$1/$2
    # If R flag is added, the server not only loads the resource at public/$1/$2 but redirects to it
    # e.g.: bamboo.jpg resides in example.com/public/media/bamboo.jpg
    #       Client asks for example.com/media/bamboo.jpg
    #       Without R flag: the URI remains example.com/media/bamboo.jpg and loads the image
    #       With R flag: the server redirects the client to example.com/public/media/bamboo.jpg and loads the image
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(css|js|images|media)/(.*)$ /public/$1/$2 [L,NC]
    # --- END

</IfModule>

下面的规则(原来在public/.htaccess中)可以被删除。事实上，同样的规则在最后两条规则中以更详细的方式进行了显式说明。

# Handle Front Controller...
#    RewriteCond %{REQUEST_FILENAME} !-d
#    RewriteCond %{REQUEST_FILENAME} !-f
#    RewriteRule ^ index.php [L]

编辑:我错过了阿比纳夫·萨拉斯瓦特的解决方案，他的答案应该是公认的。只有一个简单而明确的规则，可以将所有流量重定向到公用文件夹，而无需修改任何文件。

对于拉拉维尔 5：

将Laravel根文件夹中的server.php重命名为index.php 从/public目录复制.htaccess文件到你的Laravel根目录 文件夹中。

就是这样!
