如何使用LWP :: UserAgent接受自签名证书

问题描述

我正在尝试设置使用HTTPS的node.js服务器.然后，我将在Perl中编写脚本以向服务器发出HTTPS请求，并测量往返的延迟.

I am attempting to set up a node.js server that uses HTTPS. I will then write a scripts in Perl to make a HTTPS request to the server and measure latency of the round trip.

这是我的node.js:

Here is my node.js:

var express = require('express');
var https = require('https');
var fs = require('fs');

var key = fs.readFileSync('encrypt/rootCA.key');
var cert = fs.readFileSync('encrypt/rootCA.pem');

// This line is from the Node.js HTTPS documentation.
var options = {
  key: key,
  cert: cert
};

https.createServer(options, function (req, res) {
    res.writeHead(200);
    res.end("hello world - https\n");
}).listen(8088);

密钥/证书的生成如下:

Key/cert generation was done as follows:

openssl genrsa -out rootCA.key 2048
openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out rootCA.pem

这是我的Perl脚本:

This is my Perl script:

#!/usr/bin/perl
use LWP::UserAgent;


my $ua = LWP::UserAgent->new;
my $req = HTTP::Request->new(GET => 'https://127.0.0.1:8080');
my $res = $ua->request($req);

if ($res->is_success) {
  print $res->as_string;
} else {
  print "Failed: ", $res->status_line, "\n";
}

返回错误:

Failed: 500 Can't verify SSL peers without knowing which Certificate Authorities to trust

node.js文档描述了如何设置HTTPS服务器，但是对于生成主证书和中间证书是含糊的.

The node.js documentation describes how to set up an HTTPS server but it is vague about generating primary cert and intermediate cert.

推荐答案

要使LWP :: UserAgent忽略服务器证书，请使用以下配置:

To make LWP::UserAgent ignore server certificate use the following configuration:

my $ua = LWP::UserAgent->new;
$ua->ssl_opts(
    SSL_verify_mode => IO::Socket::SSL::SSL_VERIFY_NONE,
    verify_hostname => 0
);
