Question

我正面临着moongoose scoket cloased问题。在几个小时内启动服务器后，我遇到了这个问题。如果我向服务器发送请求我收到套接字关闭错误，并在一段时间后我得到套接字挂起错误。我的代码：

var mongoose = require('mongoose')
// here i am connecting mongo db with particular api
// mongoose.connect('mongodb://localhost/vs-court-agent')

var mongoUrl = 'mongodb://localhost/db-agent'

var connectWithRetry = function() {
  return mongoose.connect(mongoUrl, function(err) {
    if (err) {
      console.error('Failed to connect to mongo on startup - retrying in 5 sec', err);
      setTimeout(connectWithRetry, 5000);
    }
  });
};
connectWithRetry();

setInterval(function(){
  if(!mongoose.connection.readyState){
    console.log("mongo trying to reconnect")
    connectWithRetry()
  }
},1000)

路线代码：

app.post('/agent', function(req,res){
console.log(req.body)
// var newagent = new agent(req.body)
if(req.body.agentName && req.body.agentNo && req.body.agentType && req.body.agentYear){
  Agent.findOne({ agentName: req.body.agentName, agentNo: req.body.agentNo, agentType: req.body.agentType, agentYear: req.body.agentYear }, function(err, result){
        if(err){
          return res.json({info: "Unable to get data", error:err})
        }
        if(result){
          // return res.json({data: result})
          // _.merge(result, req.body)
          result.agentDetails = req.body.agentDetails
          result.save(function(error){
            if(error){
              return res.json({info: "Error while updating data", error: err})
            }
            return res.json({info: "agent updated Successfully"})
          })
        }else{
          var newAgent = new Agent(req.body, false)
          newAgent.save(function(err){
            if(err){
             return res.json({info: "Unable to create agent", error:err})
            };
            return res.json({info: 'agent Created Successfully'})
          })
        }
  })
}else{
  return res.json({info: 'agentNo,agentName,agentType,agentYear are mandatory'})
}

}）

对于mongo connect call，传递keepAlive标志的选项。当TCP套接字计时器达到零时，它将重新建立连接。 var mongoOptions = {socketOptions：{keepAlive：1}}; mongoose.connect（YOUR_URI，mongoOptions）;`

请参阅以下链接： http://mongoosejs.com/docs/connections.html

在nodejs中关闭了Moongoose Socket
