Question

我正在研究从API获取数据并使用 Socket.io 将其显示到UI的脚本，该脚本同时运行。

const express = require("express");
const app = express();
const http = require("http").Server(app);
const io = require("socket.io")(http);

function mainBody() {
oldTime = new Date().getTime();
// Set the headers
let headers = {
Authorization: "Bearer XXXXXXXXXXX",
"Content-Type": "application/json"
};
let n = 0;
let r = 0;

j = 0;
const handleResultsForRequest = function(err, response, body) {
 if (!err && response.statusCode === 200) {
  const js = JSON.parse(body);
  if (undefined !== JSON.stringify(js)) {
    const data_key = js.eventId + "_" + JSON.parse(body).start;
    data[data_key] = js;
  } else console.log("status code:" + response.statusCode);
}
};

 let array = [
    103307565,
    103771668,
    103621400,
    103675790,
    103887500,
 ];
 itemCal = 0;
 array.forEach(async function(item, index, array) {
 n = 0;
 // Configure the request
 options = {
  url: "https://api.XXXXXXXXXXXXX",
  method: "GET",
  headers: headers,
  qs: { eventId: item, pricingsummary: true, rows: "250", start: n }
};
Request(options, function(err, response, body) {
  itemCal++;
  if (err) {
    console.log("ERROR: " + err);
  } else {
    try {
      const js = JSON.parse(body);
      r = js.totalListings;
      r = Math.floor(r / 250) + 1;
      n = 0;
      for (let i = 0; i < r; i++) {
        // Configure the request
        options = {
          url:
            "https://api.XXXXXXXXXXXXXXXXXXXX",
          method: "GET",
          headers: headers,
          qs: { eventId: item, pricingsummary: true, rows: "250", start: n }
        };
        n += 250;
        Request(options, handleResultsForRequest);
      }
    } catch (e) {
      console.log(e);
    }
  }
  if (itemCal == array.length) {
    var currentTime = new Date().getTime();
    io.emit("data",diff);
    mainBody();
  }
});
});
}
mainBody();

在文件中，具有5个ID的数组在循环中执行，并且在所有循环执行后脚本的末尾都有 socket.emit（），并在发出数据mainBody（）之后再次运行，并且执行将连续运行，并在每次执行时将数据传递给客户端。

问题：：目前，我在数组中有5个ID的示例中显示此脚本在500个ID之前可以正常工作，但我输入了500至550个ID，然后返回此错误。

socket hang up

at process._tickCallback (internal/process/next_tick.js:181:9) code: 'ECONNRESET' }

并停止将数据传递给客户端。任何帮助将不胜感激。 :)预先感谢。
