同一域(localhost)上的XHR跨域错误 [英] XHR cross-domain error on the same domain (localhost)

问题描述

我在使用javascript进行某些XHR的计算机上的apache服务器上运行了一个小型Web应用程序.很长时间以来，它一直没有问题，但是今天，所有XHR都停止工作了，但只能在localhost上运行，如果您从外部访问它的话，它的运行效果很好.

I have a small web application running on apache server on a machine that uses javascript to do some XHR's. For a long time it worked with no problems, today all the XHR's stopped working but only on localhost, if you access it from outside it works perfectly.

firebug警告:使用mozilla firefox:

Using mozilla firefox, firebug warns:

"跨域请求被阻止:同一起源策略不允许在http://127.0.0.1:3581/datasnap/rest/TdssMloteamento/getLoteamento/true/处读取远程资源.可以通过将资源移至相同域或启用CORS来解决此问题."

"Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:3581/datasnap/rest/TdssMloteamento/getLoteamento/true/. This can be fixed by moving the resource to the same domain or enabling CORS."

但是我在本地主机上访问具有XHR的本地内容，该内容在同一台机器上调用了本地datasnap服务器，在本地恢复，并在网络上失败了.

But i'm on localhost acessing a local content that have XHR calls a local datasnap server on the same machine, resuming, locally it fails, and from web it works.

我正在访问URL中的apache网页:http://127.0.0.1:3582/beeWebLoteamento/Principal.php

I am acessing apache web page within url: http://127.0.0.1:3582/beeWebLoteamento/Principal.php

这对我来说完全是古怪，这毫无意义，没有逻辑，如果我使用相同的域，为什么会出现跨域错误?

This is totally, really, weird for me, that just does not make sense, no-logic, why i get a cross-domain error if i'm acessing the same domain?

我想知道发生了什么并解决此问题，以便继续在本地和通过Web(外部)进行XHR.

I want to know what is happening and solve this problem to continue doing my XHR's locally and via the web (external) too.

推荐答案

我找到了解决方案/问题，即:

将所有127.0.0.1替换为192.168.25.100(即本地计算机ip)，并且一切正常，因此请求为:

I found the solution/problem, that is:

Replaced all 127.0.0.1 to 192.168.25.100(that is the local machine ip) and everything worked fine, so the request was:

http://127.0.0.1:3581/datasnap/rest/TdssMloteamento/getLoteamento/true/

并成为:

http://192.168.25.100:3581/datasnap/rest/TdssMloteamento/getLoteamento/true/

然后我在URL中访问了我的Web应用程序(apache):

And i acessed my web application (apache) within the URL:

http://192.168.25.100:3582/beeWebLoteamento/Principal.php

恢复:

为避免这些跨域问题，请使用计算机通常以192.168.xxx.xxx开头"的本地ip地址.可以访问托管在其上的所有内容，也可以访问XHR或Apache，而不是使用127.0.0.1或localhost

Resuming:

To avoid these cross-domain problems, use the local ip address of the machine "that usually starts with 192.168.xxx.xxx" to access everything that are hosted on it, nor XHR either Apache, instead of using 127.0.0.1 or localhost
