我想创建一个HttpURLConnection的PHP脚本,并获得由脚本返回的HTTP响应。有没有办法在Perl做到这一点?
在短我想的Perl等效于以下:
java.net.URL url = new java.net.URL(urlPath);
java.net.HttpURLConnection conn = (java.net.HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestProperty("content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", Integer.toString(body.length()));
conn.setRequestProperty("Cookie", "ONTCred=" + cookie);
conn.connect();
java.io.PrintWriter pw = new java.io.PrintWriter(conn.getOutputStream());
pw.print(body); // "send" the body
pw.flush();
pw.close();
if (conn.getResponseCode() != java.net.HttpURLConnection.HTTP_OK) {
throw new java.io.IOException("Error on POST to " + url + ": " + conn.getResponseMessage());
}
// for debugging, if you want to see the header info, uncomment this section
// for (String key : conn.getHeaderFields().keySet()) {
// System.out.println("header: '" + key + "' = '" + conn.getHeaderField(key) + "'");
// }
我试图寻找类似的Perl模块,但找不到任何。 任何帮助将是非常有用。
解决方案
尝试 LWP :
# Create a user agent object
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
# Create a request
my $req = HTTP::Request->new(POST => $url);
$req->content_type('application/x-www-form-urlencoded');
# cookies
$ua->cookie_jar({ file => "$ENV{HOME}/.cookies.txt" });
# Pass request to the user agent and get a response back
my $res = $ua->request($req);
# Check the outcome of the response
if ($res->is_success) {
print $res->content;
} else {
print $res->status_line, "\n";
}
