Question

我对Socket.io和SSL有一个奇怪的问题。我在日志中看到了这一点：

可以看出，套接字因原因而关闭：运输关闭

这种情况时不时发生，间隔不一致（间隔大小为秒（10-60））。

为什么会这样？日志中没有错误。

实例化服务器的代码：

＆＃13;

var fs = require( 'fs' );
var app = require('express')();
var https        = require('https');
https.globalAgent.maxSockets = 20000;
https.globalAgent.keepAlive = true;
var server = https.createServer({
    key: fs.readFileSync('/path/to/key.key'),
    cert: fs.readFileSync('/path/to/crt/.crt'),
    ca: fs.readFileSync('/path/to/ca-bundle.crt'),
    requestCert: false,
    rejectUnauthorized: false
},app);
server.listen(4003);

var io = require('socket.io').listen(server);

＆＃13;

当使用此代码交换代码（从而禁用SSL）时，不会出现问题：

＆＃13;

var fs = require('fs');
var io = require('socket.io').listen(4002);

＆＃13;

＆＃13; `

Socket.io随机与SSL断开连接
