CORS错误在同一个域？ [英] CORS error on same domain?

问题描述

我现在遇到一个奇怪的CORS问题。

以下是错误讯息：

  XMLHttpRequest无法加载http： / localhost：8666 / routeREST / select？q = [...] 
原产地http：// localhost：8080 Access-Control-Allow-Origin不允许
  
 
 
 
两个服务器：
 
 
 
 
 
 localhost：8666 / routeREST /：这是一个简单的Python瓶子服务器。
 
 
 localhost：8080 /：Python simpleHTTPserver我运行Javascript应用程序。这个应用程式正在上方的伺服器上执行Ajax要求。
 
 
 
 
 
有什么可能的问题吗？
 
 
 
编辑：
 
 
 
而且端口是问题。感谢您的答案：）
 
 
 
如果任何人也使用Python瓶子服务器，你可以按照这篇文章的答案解决CORS问题：

解决方案
如果协议，主机 和端口是相同的：同源政策 
 
 
 
如果您要启用它，您必须遵循 cors 添加标题。 Mozilla有示例 
 
 
 
您需要在响应中将Access-Control-Allow-Origin添加为标头。允许所有人（您应该 不 ）：
  Access-Control-Allow-Origin：* 
  
 
I'm running into a weird CORS issue right now. 

Here's the error message:
XMLHttpRequest cannot load http://localhost:8666/routeREST/select?q=[...] 
Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin
Two servers:


localhost:8666/routeREST/ : this is a simple Python Bottle server.
localhost:8080/ : Python simpleHTTPserver where I run y Javascript application. This app is executing Ajax requests on the server above.


Any thought on what could be the problem?

EDIT:

And... the port was the problem. Thanks for your answers :)

If anyone is using a Python bottle server as well, you can follow the answer given on this post to solve the CORS issue:
Bottle Py: Enabling CORS for jQuery AJAX requests
解决方案
It is only considered to be the same if the protocol, host and port is the same: Same Origin Policy

If you want to enable it you must follow cors by adding headers. Mozilla has examples

You need to add Access-Control-Allow-Origin as a header in your response. To allow everyone (you should probably NOT do that): 
Access-Control-Allow-Origin: *
