#ArrestDB
ArrestDB is a "plug-n-play" RESTful API for SQLite, MySQL and PostgreSQL databases.
ArrestDB provides a REST API that maps directly to your database stucture with no configuation.
Lets suppose you have set up ArrestDB at http://api.example.com/
and a table named customers
.
To get a list of customers you would simply need to do:
GET http://api.example.com/customers/
Where customers
is the table name. As a response you would get a JSON formatted list of customers.
Or, if you only want to get one customer, then you would append the customer id
to the URL:
GET http://api.example.com/customers/123/
##Requirements
- PHP 5.3+ & PDO
- SQLite / MySQL / PostgreSQL
##Installation
Edit index.php
and change the $dsn
variable located at the top, here are some examples:
- SQLite:
$dsn = 'sqlite://./path/to/database.sqlite';
- MySQL:
$dsn = 'mysql://[user[:pass]@]host[:port]/db/;
- PostgreSQL:
$dsn = 'pgsql://[user[:pass]@]host[:port]/db/;
If you want to restrict access to allow only specific IP addresses, add them to the $clients
array:
$clients = array
(
'127.0.0.1',
'127.0.0.2',
'127.0.0.3',
);
After you're done editing the file, place it in a public directory (feel free to change the filename).
If you're using Apache, you can use the following mod_rewrite
rules in a .htaccess
file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>
Nota bene: You must access the file directly, including it from another file won't work.
##API Design
The actual API design is very straightforward and follows the design patterns of the majority of APIs.
(C)reate > POST /table
(R)ead > GET /table[/id]
(R)ead > GET /table[/column/content]
(U)pdate > PUT /table/id
(D)elete > DELETE /table/id
To put this into practice below are some example of how you would use the ArrestDB API:
# Get all rows from the "customers" table
GET http://api.example.com/customers/
# Get a single row from the "customers" table (where "123" is the ID)
GET http://api.example.com/customers/123/
# Get all rows from the "customers" table where the "country" field matches "Australia" (`LIKE`)
GET http://api.example.com/customers/country/Australia/
# Get 50 rows from the "customers" table
GET http://api.example.com/customers/?limit=50
# Get 50 rows from the "customers" table ordered by the "date" field
GET http://api.example.com/customers/?limit=50&by=date&order=desc
# Create a new row in the "customers" table where the POST data corresponds to the database fields
POST http://api.example.com/customers/
# Update customer "123" in the "customers" table where the PUT data corresponds to the database fields
PUT http://api.example.com/customers/123/
# Delete customer "123" from the "customers" table
DELETE http://api.example.com/customers/123/
Please note that GET
calls accept the following query string variables:
by
(column to order by)order
(order direction:ASC
orDESC
)
limit
(LIMIT x
SQL clause)offset
(OFFSET x
SQL clause)
Additionally, POST
and PUT
requests accept JSON-encoded and/or zlib-compressed payloads.
POST
andPUT
requests are only able to parse data encoded inapplication/x-www-form-urlencoded
.
Support for
multipart/form-data
payloads will be added in the future.
If your REST client does not support certain requests, you can use the X-HTTP-Method-Override
header:
PUT
=POST
+X-HTTP-Method-Override: PUT
DELETE
=GET
+X-HTTP-Method-Override: DELETE
Alternatively, you can also override the HTTP method by using the _method
query string parameter.
As of version 1.5.0, it's also possible to atomically INSERT
a batch of records by POSTing an array of arrays.
##Responses
All responses are in the JSON format. A GET
response from the customers
table might look like this:
[
{
"id": "114",
"customerName": "Australian Collectors, Co.",
"contactLastName": "Ferguson",
"contactFirstName": "Peter",
"phone": "123456",
"addressLine1": "636 St Kilda Road",
"addressLine2": "Level 3",
"city": "Melbourne",
"state": "Victoria",
"postalCode": "3004",
"country": "Australia",
"salesRepEmployeeNumber": "1611",
"creditLimit": "117300"
},
...
]
Successful POST
responses will look like:
{
"success": {
"code": 201,
"status": "Created"
}
}
Successful PUT
and DELETE
responses will look like:
{
"success": {
"code": 200,
"status": "OK"
}
}
Errors are expressed in the format:
{
"error": {
"code": 400,
"status": "Bad Request"
}
}
The following codes and message are avaiable:
200
OK201
Created204
No Content400
Bad Request403
Forbidden404
Not Found409
Conflict503
Service Unavailable
Also, if the callback
query string is set and is valid, the returned result will be a JSON-P response:
callback(JSON);
Ajax-like requests will be minified, whereas normal browser requests will be human-readable.
