apache mod_rewrite-将纯净网址转换为带有可变数量参数的查询字符串网址

Question

Using the following .htaccess in my application (adapted from apache mod_rewrite one rule for any number of possibilities )

RewriteCond %{REQUEST_URI} ^/api
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^([^/]+)/([^/]+)/(.*) $1?$2=$3
RewriteCond %{QUERY_STRING} (.*) 
RewriteRule ^([^/]+)/ $1/$1.php?%1

I want to convert

/api/test/1/2/3/4/5        (for any number of params as only 6 are shown after /api)

into

api/api.php?test=1&2=3&4=5    (for any number of params)

However, using https://htaccess.madewithlove.be/

I only get to step 4 below

1   RewriteCond %{REQUEST_URI} ^/api                 This condition was met.
2   RewriteCond %{REQUEST_FILENAME} !-d              This condition was met.
3   RewriteCond %{REQUEST_FILENAME} !-f              This condition was met.
4   RewriteRule ^([^/]+)/([^/]+)/(.*) $1?$2=$3       The new url is :80/api?test=1/2/3/4/5
5   RewriteCond %{QUERY_STRING} (.*)                 This rule was not met.
6   RewriteRule ^([^/]+)/ $1/$1.php?%1               This rule was not met

How do I complete the url rewrite?

Answer 1

I just modified my .htaccess file in question in the root of /api directory in my app

by removing in my original code not shown in my question

RewriteBase /api
RewriteOptions InheritDown

I am left with the following that handles only even number of tokens after api/

<IfModule mod_rewrite.c> 
    Options +FollowSymlinks
    RewriteEngine On
    DirectoryIndex api.php
    FallbackResource index.php
    RewriteCond %{REQUEST_URI} ^/api
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_URI} ^/api
    #RewriteRule (.*) $1
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{QUERY_STRING} ^(.*)$
    RewriteRule ^(.*/)([^/]+)/([^/]+) $1?$2=$3&%1 [QSA,L]
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{QUERY_STRING} ^(.*)$
    RewriteRule ^([^/]+)/ $1/$1.php?%1 [L]
</IfModule>


http://<host>/api/key1/val1/key2/val2/key3/val3/key4/val4

Now Produces a json (outputting the key value pairs) in my php script api.php

    {
        "key1": "val1",
        "key2": "val2",
        "key3": "val3",
        "key4": "val4"
    }

api.php script

<?php
    $requestURI = $_GET;

    $method = strtolower($_SERVER['REQUEST_METHOD']);
    switch ($method){
        case 'get':
             //var_dump($_GET);
             echo json_encode($requestURI);
            break;
        case 'post':
            echo json_encode($requestURI);
            break;
        case 'put':
            echo json_encode($requestURI);
            break;
        case 'delete':
            echo json_encode($requestURI);
            break;
        default:
            // unimplemented method
            http_response_code(405);
    }

EDIT: Addition of the first condition block resulted in a more correct output, see comments

    #then get handled by the 403 error document in .htaccess in /api folder

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule  (.*/)([^/]+).php$ /$1 [R=302,L]

    #Non exisitng resoruce then rewrite all items with one token to {'endpoint': <endpoint>}
    RewriteCond %{REQUEST_URI} ^/api

    RewriteCond %{REQUEST_FILENAME} !-d

    RewriteCond %{QUERY_STRING} ^(.*)$
    RewriteRule ^([^/]+)/ $1/$1.php?%1 [L]
