Add method constants to php Server class

[antonkomarev]

It may be useful when writing tests. To not hardcode method names and use constants.

Current

$response = $this->postJson(
    $browser,
    $employeeServiceServer->getPathPrefix() . 'ListEmployee',
);

Proposal

Generator may look like this:

{{- range $method := .Service.Methods }}
    public const METHOD_{{ $method.Desc.Name | upperCase }} = {{ $method.Desc.Name }};
{{- end }}

Then we will have constants for methods:

final class EmployeeServiceServer implements RequestHandlerInterface
{   
    public const METHOD_LIST_EMPLOYEE = 'ListEmployee';
}

Future usage:

$response = $this->postJson(
    $browser,
    $employeeServiceServer->getPathPrefix() . EmployeeServiceServer::METHOD_LIST_EMPLOYEE,
);

Extra

Or go further and make method to Server class which will build a full path:

public function getMethodPath(string $method): string
{
    return $this->getPathPrefix() . $method;
}

Usage:

$response = $this->postJson(
    $browser,
    $employeeServiceServer->getMethodPath(EmployeeServiceServer::METHOD_LIST_EMPLOYEE),
);
