这就是我想要做的.
我制作了一些包含 JavaScript 代码的 .html 页面,并将它们托管在 Yahoo 服务器上.
现在,当具有特定浏览器的客户端查看这些网页时,JavaScript 代码使用 XMLHTTPRequest
在 h1ttp://localhost:8080/myservlet/servlet1 建立连接以读取一些数据.
我知道,我想连接到客户端计算机上运行的 Web 服务器,如果客户端有一个,即我在我的 xmlHTTPRequest 中使用 localhost.
但是,即使客户端在端口 8080 上运行 Web 服务器,这也不起作用.在客户端的计算机上,我可以访问 http://localhost:8080/mysevlet/servlet1
并且 servlet 是运行良好,但通过 Yahoo 服务器上托管的 .html
页面无法正常工作.
我在这里做错了什么?

您无法访问不在您域中的内容,除非它是返回 XML 或 JSONP 的 Web 服务
this is what I am trying to do.
I have made a few .html pages with JavaScript code in it and hosted them on a Yahoo server.
Now when a client with a certain browser views these web pages, the JavaScript code uses XMLHTTPRequest
to make a connection at h1ttp://localhost:8080/myservlet/servlet1 to read some data.
I know, I want to connect to the web server running on the client's computer if the client has one i.e. I am using localhost in my xmlHTTPRequest.
But this is not working even when a client has a web server running on port 8080. On the client's computer I can access http://localhost:8080/mysevlet/servlet1
and the servlet is running fine, but through the .html
page hosted on Yahoo server it does not work.
Anything that I am doing wrong here?

You cannot access what is not on your domain, unless it is a Web Service returning XML or JSONP
