Simplon/Border

A small library to handle http requests and responses including JSON-RPC., _(*1)

Version

0.5.2, _(*2)

How to install

Since this library is build with PHP 5.4 syntax you are required to have it installed. Simplon/Border can bei installed by either downloading it from github or via Composer. I encourage you to do the latter. Here is a snippet from a possible composer.json file:, _(*3)

{
  "require": {
    "php": ">=5.4",
    "simplon/border": "0.5.2"
  }
}

Request object

The request class is basically an interface wrapper for PHP's $_SERVER variable. I also added some methods which help to identify/handle JSON-RPC requests., _(*4)

Examples

Just a couple of calls to show you how we roll. Have a look at the class to see all methods:, _(*5)

// print request method
echo Request::getInstance()->getMethod();

// print request uri
echo Request::getInstance()->getUri();

// print query string
echo Request::getInstance()->getQueryString();

// print remote ip
echo Request::getInstance()->getRemoteIp();

How to handle JSON-RPC requests?, _(*6)

// is that a json-rpc request?
if(Request::getInstance()->isJsonRpc())
{
  // print request id
  echo Request::getInstance()->getJsonRpcId();

  // print method
  echo Request::getInstance()->getJsonRpcMethod();

  // print params | array
  var_dump(Request::getInstance()->getJsonRpcParams());
}

Response object

In the demand of talking HTTP? The response class does exactly that. You can use it to respond to a http request by sending:, _(*7)

• status codes (e.g. 200, 400, 500 ...)
• initiating a file download
• initiating a streaming process (chunking)
• return to referer
• json-rpc response
• json response
• html response
• text
• redirect to another address

Examples

Here are a couple of examples. Have a look at the class to see all:, _(*8)

// initiating file download
(new Response())->sendFile('/your/file/path/file.pdf', 'application/pdf');

// talk json-rpc
(new Response())->sendJsonRpc('result', ['name' => 'hansi'], 1);

// talk json
(new Response())->sendJson(['name' => 'hansi']);

// send status code
(new Response())->sendStatusCode(500);
