Node.JS，服务器关闭请求中的Keep-Alive连接

Question

我有Node.js HTTP服务器，如果它们的空闲时间为10秒，并且使用Keep-Alive连接池请求此服务器的客户端，它将关闭传入连接。当我以10秒的间隔开始发送请求时，我定期收到错误消息ECONNRESET，我想因为连接在HTTP请求中间关闭。除简单的重新发送请求外，是否有任何优雅的解决方案

server.js

var server = require('http').createServer(function(req, res) { 
    console.log(new Date(), "Request ", req.method); 
    res.end("Nice"); 
}); 

server.timeout = 10000; 

server.on("connection", function(socket) { 
    console.log("New connection"); 
    socket._created = new Date().getTime(); 
    socket.on("close", function() { 
    var now = new Date().getTime(); 
    console.log(new Date(), "Socket closed, TTL", (now - socket._created)/1000); 
    }); 
}); 
server.listen(3000); 

client.js

var http = require("http"); 

var agent = new http.Agent({ 
    keepAlive: true 
}); 

var reqSent = 0; 
var NEED_REQS = 10; 
var TIMEOUT = 10000; 

function _req() { 
    var start = new Date().getTime(); 
    var req = http.get({ 
    host: "localhost", 
    port: 3000, 
    agent: agent 
    }, function(res) { 
    reqSent++; 
    var now = new Date().getTime(); 
    console.log("Sent:", reqSent, (now - start)/1000); 

    if(reqSent >= NEED_REQS) { 
     agent.destroy(); 
     return; 
    } 
    res.setEncoding('utf8'); 
    res.on('data', function (chunk) { 
    }); 

    setTimeout(function() { 
     _req(); 
    }, TIMEOUT); 
    }); 
    req.on("error", function(err) { 
    console.error(err); 
    }); 
} 

_req(); 

运行client.js

$ node client.js

{ [Error: read ECONNRESET] code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' }

我认为有只有一个解决方案 - 重发请求，如果ECONNRESET获得，我发现很好的lib包装这样的逻辑https://github.com/FGRibreau/node-request-retry
