There is no explicit handling for errors that might occur on the request (req) object itself

[jiangcuo]

What happened?

Error reported as follows

node:events:489
      throw er; // Unhandled 'error' event
      ^

Error: connect ECONNREFUSED 10.10.10.54:8006
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1570:16)

}

In the code below does not handle the req error

Lines 295 to 340 in c58f4cb

	let req = this.#http.request(options, (response) => {
	response.setEncoding("utf8");
	let chunks = "";
	response.on("data", (chunk) => {
	chunks += chunk;
	});
	response.on("end", () => {
	let data = null;
	if (ref.responseType == ResponseType.JSON) {
	data = JSON.parse(chunks);
	} else if (ref.responseType == ResponseType.PNG) {
	data = "data:image/png;base64," + chunks;
	}
	const result = new Result(
	data,
	response.statusCode,
	response.statusMessage,
	resource,
	parameters,
	response.method,
	ref.responseType
	);
	ref.#lastResult = result;
	//debug
	this.#log(result.toString());
	this.#log(result.response);
	resolve(result);
	});
	response.on("error", (error) => {
	this.#error(error);
	reject(error);
	});
	});
	if (body != "") {
	req.write(body);
	}
	req.end();

We can add an error event listener on the req object to handle potential request errors.

req.on('error', (error) => {
  this.#error(error);  
  reject(error);     
});

This way we can use catch to handle errors in our own code
