如何使用Javascript/Ajax但不使用jQuery获取远程URL的状态代码? [英] How to get status code of remote url using Javascript/Ajax but NOT using jQuery?

问题描述

我正尝试在不使用jQuery或从该URL加载图像的方法的情况下，检查URL是否可访问或是否使用javascript.如果我可以获取该网址的状态码，那将是很好的，因为我只关心状态码为200.

I am trying to check if a url is reachable or not using javascript without using jQuery or the method of loading an image from that url. It would be great if I can get the status code of that url, because all I care about is that status code being 200.

我已经尝试过XMLHttpRequest，但是我了解到它不支持跨域调用.

I have tried XMLHttpRequest but I learned that it does not support cross domain calls.

请帮助.

谢谢.

推荐答案

使用

Create a server side script using a server side language, have this script return the status code. This "proxy" script, will request the URL for you, so that no cross domain requests need to be made.

有关Python响应代码脚本的示例，请参见此处:从URL获取HTTP响应代码的最佳方法是什么?

For an example of a Python response code script, see here: What’s the best way to get an HTTP response code from a URL?
