亚马逊网络刮板

Question

在此网络刮板上工作，

const express = require("express");
const request = require("request-promise");

const app = express();
const PORT = process.env.PORT || 5000;

const apiKey = "";
const baseUrl = "http://api.scraperapi.com?api_key=${apiKey}&autoparse=true";

app.use(express.json());

app.get("/", (req, res) => {
  res.send("Welcome to Scraper API.");
});

//GET Product details
app.get("/products/:productId", async (req, res) => {
  const { productId } = req.params;

  try {
    const response = await request(`enter code here`
      `${baseUrl}&url=https://www.amazon.com/dp/${productId}`
    );

    res.json(JSON.parse(response));
  } catch (error) {
    res.json(error);
  }
});

app.listen(PORT, () => console.log("Server running on port ${PORT}"));
When I run it through the browser choosing a product ID from Amazon 

我会得到以下

Answer 1

这里：

const apiKey = "";
const baseUrl = "http://api.scraperapi.com?api_key=${apiKey}&autoparse=true";

如果您使用实际的空字符串作为API密钥，而不仅仅是为此问题省略它服务器正常抱怨：

“ statuscode”：401，“消息”：“ 401-”未经授权的请求，请做出
确保您的API密钥有效。”
