是否可以像多部分请求一样提供HTTP多部分响应(使用Perl /
PHP)？场景就像是,我想提供一个URL,它为EmployeeID提供一个参数,作为回报,响应应该包括员工的照片,最新的工资单以及姓名,年龄和地址等信息.接收端不是浏览器,但它将是一个获得此响应并稍后处理它们的程序.有关如何做到这一点的任何想法？
为了提供有关上述问题的更多信息,我必须向我的朋友提供一个URL,以便以编程方式接收回复.对于例如(在Perl中)：
$response = $ua->request($my_url)
我的应用程序应该不仅响应数据,还响应文件！我被要求让它返回多部分回复.
我现在不知道如何从编码本身开始.谷歌搜索“多部分响应”没有返回我可以学习和开始的页面.然而,chansen的评论非常有用,以及他的代码示例https://gist.github.com/1391017.非常感谢.
解决方法

#!/usr/bin/perl
use strict;
use warnings;
use HTTP::Response;
my $response = HTTP::Response->new(
200,'OK',[ 'Content-Type' => 'multipart/form-data' ]
);
$response->protocol('HTTP/1.1');
$response->date(time);
$response->server('Foo/1.0');
my $name = HTTP::Message->new([
'Content-Type' => 'text/plain; charset=UTF-8','Content-Disposition' => 'form-data; name="name"',],'John Doe');
$response->add_part($name);
my $note = HTTP::Message->new([
'Content-Type' => 'text/plain; charset=UTF-8','Content-Disposition' => 'form-data; name="note"',<<'NOTE');

$response->add_part($note);
my $blob = HTTP::Message->new([

$blob->add_content('a chunk');
$blob->add_content(' of data');
$response->add_part($blob);
print $response->as_string;
输出：
