# NAME

HTTP::Request::FromCurl - create a HTTP::Request from a curl command line

# SYNOPSIS

    my $req = HTTP::Request::FromCurl->new(
        # Note - curl itself may not appear
        argv => ['https://example.com'],
    );

    my $req = HTTP::Request::FromCurl->new(
        command => 'https://example.com',
    );

    my $req = HTTP::Request::FromCurl->new(
        command_curl => 'curl -A mycurl/1.0 https://example.com',
    );

    my @requests = HTTP::Request::FromCurl->new(
        command_curl => 'curl -A mycurl/1.0 https://example.com https://www.example.com',
    );
    # Send the requests
    for my $r (@requests) {
        $ua->request( $r->as_request )
    }

# METHODS

## `->new`

    my $req = HTTP::Request::FromCurl->new(
        # Note - curl itself may not appear
        argv => ['--agent', 'myscript/1.0', 'https://example.com'],
    );

    my $req = HTTP::Request::FromCurl->new(
        # Note - curl itself may not appear
        command => '--agent myscript/1.0 https://example.com',
    );

The constructor returns one or more [HTTP::Request::CurlParameters](https://metacpan.org/pod/HTTP::Request::CurlParameters) objects
that encapsulate the parameters. If the command generates multiple requests,
they will be returned in list context. In scalar context, only the first request
will be returned.

    my $req = HTTP::Request::FromCurl->new(
        command => '--data-binary @/etc/passwd https://example.com',
        read_files => 1,
    );

## `->squash_uri( $uri )`

    my $uri = HTTP::Request::FromCurl->squash_uri(
        URI->new( 'https://example.com/foo/bar/..' )
    );
    # https://example.com/foo/

Helper method to clean up relative path elements from the URI the same way
that curl does.

# GLOBAL VARIABLES

## `%default_headers`

Contains the default headers added to every request

## `@option_spec`

Contains the [Getopt::Long](https://metacpan.org/pod/Getopt::Long) specification of the recognized command line
parameters.

The following `curl` options are recognized but ignored:

- ` --dump-header `
- ` --include `
- ` --progress-bar `
- ` --silent `
- ` --verbose `

# KNOWN DIFFERENCES

## Incompatible cookie jar formats

Until somebody writes a robust Netscape cookie file parser and proper loading
and storage for [HTTP::CookieJar](https://metacpan.org/pod/HTTP::CookieJar), this module will not be able to load and
save files in the format that Curl uses.

## Loading/saving cookie jars is the job of the UA

You're expected to instruct your UA to load/save cookie jars:

    use Path::Tiny;
    use HTTP::CookieJar::LWP;

    if( my $cookies = $r->cookie_jar ) {
        $ua->cookie_jar( HTTP::CookieJar::LWP->new()->load_cookies(
            path($cookies)->lines
        ));
    };

## Different Content-Length for POST requests

## Different delimiter for form data

The delimiter is built by [HTTP::Message](https://metacpan.org/pod/HTTP::Message), and `curl` uses a different
mechanism to come up with a unique data delimiter. This results in differences
in the raw body content and the `Content-Length` header.

# MISSING FUNCTIONALITY

- File uploads / content from files

    While file uploads and reading POST data from files are supported, the content
    is slurped into memory completely. This can be problematic for large files
    and little available memory.

- Sequence expansion

    Curl supports speficying sequences of URLs such as
    ` https://example.com/[1-100] ` , which expands to
    ` https://example.com/1 `, ` https://example.com/2 ` ...
    ` https://example.com/100 `

    This is not (yet) supported.

- List expansion

    Curl supports speficying sequences of URLs such as
    ` https://{www,ftp}.example.com/ ` , which expands to
    ` https://www.example.com/ `, ` https://ftp.example.com/ `.

    This is not (yet) supported.

- Multiple sets of parameters from the command line

    Curl supports the `--next` command line switch which resets
    parameters for the next URL.

    This is not (yet) supported.
