我目前正在尝试使用socket.io创建一个安全连接，但是目前我真的无法实现。为了检查我的证书是否正确，我尝试在nodeJS中创建了一个基本的https服务器。
var fs = require('fs');
var certDir = "/path/to/the/certificates/cert-test/";
require("https").createServer(
{
key : fs.readFileSync(certDir + 'srv.key'),
cert : fs.readFileSync(certDir + 'crt.pem'),
},
function(request, response){
response.writeHeader(200, {"Content-Type": "text/plain"});
response.write("Hello World!\n");
response.end();
}).listen(8082).on('clientError', function(e){
console.log(e);
});
等同于http的情况运行良好，但是这个无法使其工作。我升级了节点版本到v0.12.4，npm到2.11.0，https到1.0.0（进一步查询socket.io为1.3.5）。服务器在AWS上，使用bitnami实例，Ubuntu 12.04.5 LTS，内核版本为3.2.0-84-virtual，并且OpenSSL为1.0.1i。
我尝试通过https://node.foobar.com:8082（在浏览器和curl中）访问服务器，但我从未完成过适当的握手。
服务器检测到以下错误：
- [错误：3074971392：错误：1408A0C1：SSL例程：SSL3_GET_CLIENT_HELLO：没有共享密码：../deps/openssl/openssl/ssl/s3_srvr.c:1389：] - [错误：3074971392：错误：140A1175：SSL例程：SSL_BYTES_TO_CIPHER_LIST：不合适的回退：../deps/openssl/openssl/ssl/ssl_lib.c:1481：]
我尝试检查服务器上可用的密码和我的计算机上可用的密码，发现有很多匹配项。所以，各位，我真的没有想法了，我会感激您能提供帮助...

顺便问一下，除了将`http` 改成 `https`来请求 `socket.io/socket.io.js` 文件以创建连接之外，我是否还需要改变其他内容才能在我的网站上使用此软件包？
谢谢。
openssl s_client -connect my.url.com:8082 -tls1 -servername my.url.com超时了。看起来没有服务器在监听。您能否验证该端口上是否有服务器正在监听？ - jwwnode.inkive.com:8082后触发了一个过滤器。现在我立即收到connect: Connection refused。看起来有东西在监听该端口，但它并没有使用 HTTP 或 HTTPS 进行通信。如果您没有被禁止，请尝试使用-tls1_2的s_client。我知道-ssl3和tls1不起作用。 - jww
