使用SSL UNABLE_TO_VERIFY_LEAF_SIGNATURE的Node.js错误

Question

系统:Windows 7

NodeJS版本:0.10.2

WS模块:ws,最后一个版本

错误:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE
    at SecurePair. (tls.js:1283:32)

服务器:

(function(){

    "use strict";

    var fs = require('fs');

    // you'll probably load configuration from config
    var cfg = {
        ssl: true,
        port: 8080,
        ssl_key: 'crt/server1.key',
        ssl_cert: 'crt/server1.crt'
    };

    var httpServ = require('https') 

    var WebSocketServer   = require('ws').Server;

    var app      = null;

    // dummy request processing
    var processRequest = function( req, res ) {

        res.writeHead(200);
        res.end("All glory to WebSockets!\n");
    };

    if ( cfg.ssl ) {

        app = httpServ.createServer({

            // providing server with  SSL key/cert
            key: fs.readFileSync( cfg.ssl_key ),
            cert: fs.readFileSync( cfg.ssl_cert ),
            //requestCert: true,
            //rejectUnauthorized: false

        }, processRequest ).listen( cfg.port );

    } else {

        app = httpServ.createServer( processRequest ).listen( cfg.port );
    }

    // passing or reference to web server so WS would knew port and SSL capabilities
    var wss = new WebSocketServer( { server: app } );


    wss.on( 'connection', function ( wsConnect ) {

        wsConnect.on( 'message', function ( message ) {

            console.log( message );

        });

    });


}());

客户:

var WebSocket = require('ws');
var ws = new WebSocket('wss://localhost:8080');
ws.on('open', function() {
    ws.send('something');
});

证书确认.

帮助>请!

我正在使用一个名为"superagent"的包并得到同样的错误.在尝试了几个可能的修复之后,我遇到了一个对我来说100%有效的方法:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

没有必要做任何要求或者其他任何事情:只需在网络呼叫之前将其添加到您的代码中,您就可以了.

WebSocket客户端可能不完全信任您的示例中服务器使用的SSL证书,因此NodeJS在客户端的网络库中引发错误.

您需要设置rejectUnauthorized为false(这是大多数高级网络库允许您通过传递到较低级别NodeJS网络库的选项进行设置的选项).

我浏览了ws模块源代码,看起来你应该试试这个:

var ws = new WebSocket('wss://localhost:8080', null, {rejectUnauthorized: false});

注意:rejectUnauthorized应仅false在测试/开发期间.生产应用程序应始终rejectUnauthorized: true用于完全安全.

我以前遇到过类似的问题，你可以尝试使用 https.globalAgent.options.secureProtocol = 'SSLv3_method' https设置SSLv3连接。
