检查网站是否可以联系 [英] Check if website is contactable

问题描述

我想检查一个特定的网站是否在线。网站的名称来自输入字段，并通过邮件发送。

I want to check if a specific website is online. The name of the website comes from an input field and is sending via post.

有一个用于ping主机的NPM模块，但这不足以帮助我。我需要一个使用参数检查URL的解决方案，如： hostname.com/category

There is an NPM module for ping hosts, but this do not help me so much. I need a solution for checking URL's with params, like: hostname.com/category

我将不胜感激建议。

推荐答案

只需进行HTTP请求。

Just make an HTTP request.

var http = require('http');
http.get('http://example.com/category', function (res) {
  // If you get here, you have a response.
  // If you want, you can check the status code here to verify that it's `200` or some other `2xx`.

}).on('error', function(e) {
  // Here, an error occurred.  Check `e` for the error.

});;
