我有一个如下的JSON文件。尽管文件本身看起来不必要地冗长，但我将其包含在内是有原因的。基本上，对我来说，我的文件太大了，无法通过TCP到达我的活动站点。

"Team_Members": 15,
"Team_Mascot": "Too"
},
{
"Team_Name": "Long",
"Team_Members": 16,

},
{

]
}
]
}
我用来解析的Node.js代码如下：
var express = require('express');
var net = require("net");
var fs = require("fs");
var request = require('request');
var app = express();
var server = net.createServer();
var pack;
app.use(function(req, res, next){
res.header("Access-Control-Allow-Origin", "*");
next();
});
server.on("connection", function(socket){
pack = "";
socket.setEncoding('utf8');
socket.on("data", function(d){
pack = JSON.parse(d);
console.log(pack.Timestamp.LocalTimestamp);
app.set('dee', d);
app.get("/"+pack.FormatNumber, function(req, res){
res.writeHead(200, {'Content-Type': 'text/plain'});
res.write(req.app.get('dee'));
res.end();
});
});
socket.once("close", function(){
console.log("connection closed");
});
});
server.on("error", function(){
console.log("connection error");
});
server.listen(9000, function(){
console.log("Server Listening to Port 9000");
});
app.listen(8081, function(){
});
该JSON文件以TCP数据包的形式发送到我的Node服务器，该服务器依次对其进行解析。该代码和功能可以在我的本地主机环境中完美运行。但是，当尝试通过Digitalocean Node.js服务器推送JSON文件时，出现以下错误。
undefined:57
"Cha
^
SyntaxError: Unexpected token C
at Object.parse (native)
at Socket.<anonymous>
at emitOne (events.js:77:13)
at Socket.emit (events.js:169:7)
at readableAddChunk (_stream_readable.js:146:16)
at Socket.Readable.push (_stream_readable.js:110:10)
at TCP.onread (net.js:523:20)
如果我减少JSON数组中的对象数量，则将其传递到实时服务器即可。我不清楚为什么会这样。TCP数据包仅通过较小的JSON文件进行解析。
尽管TCP通过IP数据包发送数据，但TCP并不是数据包协议。TCP套接字只是数据流。因此，将
data事件视为逻辑消息是不正确的。换句话说，socket.write一端不等于另一端的单个data事件。单个data事件可能包含多个消息，单个消息或仅消息的一部分。
好消息是这是一个已经解决了很多次的问题。我建议：
