curl-builder

curl-builder is a curl command generator which can generate curl commands automatically from PSR-7 server requests and manually by specifying options and URL.

Installation

composer require alexkart/curl-builder

Examples

Generating curl command from PSR-7 request

$request = new Request('POST', 'http://example.com', [
    'Connection' => ['keep-alive'],
    'Accept' => [
        'text/html',
        'application/xhtml+xml',
    ],
], 'data');
$command = new Command();
$command->setRequest($request);
$curl = $command->build();
// curl -H 'Connection: keep-alive' -H 'Accept: text/html, application/xhtml+xml' -d 'data' http://example.com

Constructing curl command manually

$command = new Command();
$command->setUrl('http://example.com');
$command->addOption('-v');
$command->addOption('-H', 'Connection: keep-alive');
$command->addOption('-H', 'Cache-Control: max-age=0');
// curl -v -H 'Connection: keep-alive' -H 'Cache-Control: max-age=0' http://example.com

Adding options

Options can be added to the command one by one with addOption()

$command->addOption('-L');
$command->addOption('-v');
$command->addOption('-H', 'Connection: keep-alive');
// curl -L -v -H 'Connection: keep-alive' ...

or add several of them at once with addOptions()

$command->addOption('-v');
$command->addOptions([
    '-L',
    '-d' => 'test'
]);
// curl -v -L -d 'test' ...

setOptions() can be used to override previously set options

$command->setOptions(['-L', '-v']);
// curl -L -v ...

addOptions() and setOptions() formats:

// options without arguments
// the following lines will generate the same command
$command->setOptions(['-L' => [null], '-v' => [null]]);
$command->setOptions(['-L' => null, '-v' => null]);
$command->setOptions(['-L', '-v']);
// curl -L -v ... 

// options with arguments
$command->setOptions(['-H' => 'test']);
// curl -H 'test' ...
$command->setOptions(['-H' => ['test1', 'test2']]);
// curl -H 'test1' -H 'test2'

Specifying command template

Default template for the command is {name}{option}{url}. But you can change it with setTemplate() method

$command = new Command();
$command->setUrl('http://example.com');
$command->addOption('-v');
$command->addOption('-L');
$curl = $command->build();
// curl -v -L http://example.com

// change order
$command->setTemplate(Command::TEMPLATE_COMMAND_NAME . Command::TEMPLATE_URL . Command::TEMPLATE_OPTIONS);
$curl = $command->build();
// curl http://example.com -v -L

// remove options
$command->setTemplate(Command::TEMPLATE_COMMAND_NAME . Command::TEMPLATE_URL);
$curl = $command->build();
// curl http://example.com

Quoting and escaping arguments

By default arguments are quoted with single quotes and if single quote appears in the argument it will be escaped

$command->addOption('-d', 'data');
// curl -d 'data'

$command->addOption('-d', "data'1");
// curl -d $'data\'1'

Quoting character can be changed to double quote or removed

$command->addOption('-d', 'data1');
$command->addOption('-d', 'data"2');
$command->setQuoteCharacter(Command::QUOTE_CHARACTER_DOUBLE);
// curl -d "data" -d "data\"2"

$command->addOption('-d', 'data');
$command->setQuoteCharacter(Command::QUOTE_CHARACTER_NONE);
// curl -d data
