将 try-catch 用于 https 但没有发现任何错误

[英]using try-catch for https but don't catch any error

我正在使用 HTTPS 从网站获取数据,我想做的是捕捉任何可能发生的错误,但问题是它什么也没捕捉到,所以这是我的主要代码

test = async() => {
  console.log("Hellow")
  now = new Date();
  const https = require("https");
  https.get("website",{ agent: proxyy },
    (res) => {
      var body = "";
      res.on("data", function (chunk) {
        body += chunk;
      });
      res.on("end", function () {
        var resp = JSON.parse(body);
        data_wanted = resp.data
        const desiredItem = data_wanted.find((item) =>
          item.name.includes("data")
        );
        console.log(desiredItem)
      });
    }
  );
};

我尝试了多种方法来捕获这样的错误

async function run() {
  try {
     await test();
  } catch (error) {
    console.log(error)
  }
  

也是这样

async function f() {
  try{
  run = await test()
}catch(e){
  console.log("Hello world")
}

}

it tried using the try-catch inside the function but also didn't works, my best guess that the try-catch is being executed before the function finish fetching

编辑1 :所以我的真正意图是做一个while循环,不断尝试直到没有错误

const https = require('https');

https.get('https://encrypted.google.com/', (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });

}).on('error', (e) => {
  console.error(e);
});
