通过 NodeJS 中的代理返回 API JSON

Question

在通过代理发送我的请求后，我正在尝试控制台记录 json 的 API，但是当代码运行时，控制台不会记录任何内容。 这是我的代码。

const express = require('express');
const app = express();
const fetch = require('node-fetch')

app.listen(3000, () => console.log('listening at 3000'));
app.use(express.static('public'));
app.use(express.json())

app.post('/api', (request, response) => {
    let steamIdValue = request.body.steamId
    let steamInventoryApiLink = 'https://steamcommunity.com/profiles/' + steamIdValue + '/inventory/json/730/2'

    require('request-promise')({
        url: 'xxxxx',
        proxy: 'xxxxx'
    }).then(function(data){

        const request = require('request');

        request({
          'url': steamInventoryApiLink,
          'method': "GET",
          'proxy':'http://' + data + ':80'
        },function (error, response, body) {
          if (!error && response.statusCode == 200) {
            console.log(body);
          }
        })
        
        
        }, function(err){ console.error(err); });

});

go 是否有解决方案或更好的方法来执行此操作？

以下是建议更改的日志

（在请求中使用“request-promise”并记录错误，以及 ip 地址。）

你有一个 if 语句。 如果状态码不是 200，但仍以某种方式被接受为“非错误”，则错误捕获不起作用，因此在 if 中添加 else 并在其中记录错误消息，或者删除 if 语句以获取不管是什么反应。
