Perl学习笔记，十一--发送http请求

Perl发送http请求依赖于LWP模块，模块的安装可以使用ppm，也可以去cpan下载后自行安装。

#发送一个get请求：

 use LWP::UserAgent;
  $ua = LWP::UserAgent->new;
  $ua->agent("$0/0.1 " . $ua->agent);
  # $ua->agent("Mozilla/8.0") # pretend we are very capable browser

  $req = HTTP::Request->new(
     GET => 'http://www.baidu.com');
  $req->header('Accept' => 'text/html');

  # send request
  $res = $ua->request($req);
  print $res->decoded_content;

　　#发送一个post请求

    use LWP::UserAgent;  
     my $ua = LWP::UserAgent->new;  
     my $req = HTTP::Request->new('POST' => 'http://localhost:8080/webtest/a.jsp');  
     $req->content_type('application/x-www-form-urlencoded');#post请求,如果有发送参数，必须要有这句  
     $req->header('Cookie' => "key1=value1;key2=value2"); #如果想发送cookie，则需这句  
     $req->header('Accept-Language' => 'zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3');#如需发送请求头，  #只需像这行代码一般  
     $req->content("name=zhangsan&);#发送post的参数  
     my $res = $ua->request($req);  
     print $res->status_line."\n";  
     print $res->as_string();#获取的是原始内容，包括响应头，响应正文  
      #$res->content();获取的是响应正文  

　　这个是个完整的处理了
