JQuery getJSON CORS错误，即使没有交叉原点请求？ [英] JQuery getJSON CORS error even though not making Cross Origin Request?
问题描述
我的学校服务器上的Pi上部署了我的网站。 JS包含对同一个域进行GET请求的调用。 （它运行Flask）。为什么这是一个跨域的请求，当我不试图去一个不同的域？
I have my website deployed on a Pi on my school server. The JS contains calls that make a GET request to the same domain. (It runs Flask). Why is this considered a cross origin request when I'm not trying to hit a different domain?
我的js脚本是在一个目录以外的文档根目录。您也可以直接在浏览器中检查元素。
My js scripts are in a directory other than the document root. You can also inspect the elements in the browser directly.

推荐答案
测试交叉来源时，端口号被视为域的一部分请求，所以它必须和请求页面一样进入相同的端口。您的网站是 http://dvc-raspberrypi.ucsd.edu/ ，但是您正尝试访问 http：// dvc-raspberrypi。 ucsd.edu:5000/door 。端口5000使他们不同的起源。
Port numbers are considered part of the domain when testing cross-origin requests, so it has to be going to the same port as the requesting page. Your website is http://dvc-raspberrypi.ucsd.edu/, but you're trying to access http://dvc-raspberrypi.ucsd.edu:5000/door. Port 5000 makes them different origins.
