Parable Http

Parable Http is a minimalist Http library used to receive requests and send responses. It is not a full implementation, offering just-enough functionality.

Install

Php 8.0+ and composer are required.

$ composer require parable-php/http

Usage

To create a Request object automatically from the server variables, use:

$request = RequestFactory::createFromServer();

To create a Request from scratch, use:

$request = new Request(
    'GET', 
    'http://url.here/path?param=value'
);

To set up a minimal response you want to send to the client:

$response = new Response(200, 'This is the body');

And to send it, use the Dispatcher:

$response = new Response(200, 'This is the body');
$dispatcher = new Dispatcher();

$dispatcher->dispatch($response);

This will send a response with stat us code 200, with the body set as passed to the Response upon creation.

API

Request

• getMethod(): string - returns GET, POST, etc.
• getUri(): Uri - return a Uri object representing the uri being requested
• getRequestUri(): ?string - the path of the Uri
• getProtocol(): string - the protocol used (i.e. HTTP/1.1)
• getProtocolVersion(): string - the version part of the protocol (i.e. 1.1)
• getBody(): ?string - the body of the request, if any
• getUser(): ?string - the username from the uri
• getPass(): ?string - the password from the uri
• isHttps(): bool - whether the request was made over https. This represents a 'best guess' based on multiple checks
• isMethod(string $method): bool - check whether the method matches $method

From the HasHeaders trait:

• getHeader(string $header): ?string - get a single header by string, null if non-existing
• getHeaders(): string[] - get all headers

Response

• getBody(): ?string - the body to be sent
• setBody(string $body): void - set the body as a string
• prependBody(string $content): void - prepend the value to the body
• appendBody(string $content): void - append the value to the body
• getContentType(): string - the content type (i.e. text/html, application/json)
• setContentType(string $contentType): void - set the content type
• getProtocol(): string - the protocol to be sent with (i.e. HTTP/1.1)
• getProtocolVersion(): string - the protocol version (i.e. 1.1)
• setProtocol(string $protocol): void - set the protocol
• setHeaders(array $headers): void - set multiple headers, resetting
• addHeaders(array $headers): void - add multiple headers
• addHeader(string $header, string $value): void - add single header

From the HasHeaders trait:

• getHeader(string $header): ?string - get a single header by string, null if non-existing
• getHeaders(): string[] - get all headers

From the HasStatusCode trait:

• getStatusCode(): int - the status code to be sent (i.e. 200)
• getStatusCodeText(): ?string - the status code text to be sent (i.e. OK)
• setStatusCode(int $statusCode): void - set the status code

Dispatcher

• dispatch(Response $response): void - dispatch a Response, sending all its content as set
• dispatchAndTerminate(Response $response, int $exitCode = 0): void - dispatch a Response and terminate, i.e., ending program flow immediately afterwards
