表达发送不完整的响应json数据

Question

The version info: "express": "~4.15.2", "express-session": "^1.15.5",

I use this code send large json data to client:

   router.get('/exportAllData',function(req,res,next){
    async function getData(){
    let sql="SELECT * FROM int_information "
    let rows=await query(sql);
    let data=await JSON.stringify(rows);
    return JSON.parse(data);
  }
  getData().then(data=>res.send({flag:1,data:data})).catch(error=>{
    res.send({flag:0,err:error});
  });  
})

I tried wget localhost on server and can get full data, But the remote client got broken json data and different each time refresh. Where is the problem? Seems response closed before get all data.

This is an open bug in node js 8.x, I use 7.10 solved this problem. Or you can set server.keepAliveTimeout=30000 in app.js to extend timeout setting
