设置 HTTP 请求记录器的最简单方法是什么

在本地设置某些内容以侦听自定义端口上的 GET 请求的最简单方法是什么？

这样我就可以做curl -X GET -i 'localhost:34331/hello'

验证是否收到请求并检查请求以查看标头（如果发送了标头）以及用于请求的 URL

答案1

您可以使用netcat。就像是：

nc -l 34331

-v如果你想查看调用的详细信息，使用curl的选项并调用真实的服务会更容易。

curl -v http://www.google.com > /dev/null
* Connected to localhost (127.0.0.1) port 3128 (#0)
> GET http://www.google.com/ HTTP/1.1
> Host: www.google.com
> User-Agent: curl/7.47.0
> Accept: */*
> Proxy-Connection: Keep-Alive
>

答案2

如果您安装了 Perl，则可以使用 HTTP::Daemon 模块（您需要在 Perl 库中拥有该模块）编写一个非常简单的 http 守护进程：

#!/usr/bin/perl
use strict;
use HTTP::Daemon;
use HTTP::Response;
use threads;

my $httpd = HTTP::Daemon->new( LocalPort => 8081, Listen => 20, Reuse=>1) || die;
print "httpd started...\n";

sub process_one_req
{
  my $con = shift;
  my $rq = $con->get_request;

  print "<< ".$rq->uri." : ".$rq->header('User-Agent')."\n";

  my $rsp = HTTP::Response->new(200, 'OK' );
  $con->send_response($rsp);
} 

while (my $con = $httpd->accept)
{
 process_one_req $con;
}
