Question

I'm using .htaccess to rewrite urls and I used html base tag in order to make it work.(我正在使用.htaccess重写网址，我使用了html基本标记以使其正常工作。)

Now, when I try to make an ajax request I get the following error:(现在，当我尝试发出ajax请求时，我收到以下错误：) XMLHttpRequest cannot load http://www.example.com/login.php .(XMLHttpRequest无法加载http://www.example.com/login.php 。) No 'Access-Control-Allow-Origin' header is present on the requested resource.(请求的资源上不存在“Access-Control-Allow-Origin”标头。) Origin ' http://example.com ' is therefore not allowed access.(因此，不允许来源“ http://example.com ”访问。)   ask by Th3lmuu90 translate from so

Use addHeader Instead of using setHeader method,(使用addHeader而不是使用setHeader方法，)

response.addHeader("Access-Control-Allow-Origin", "*"); * in above line will allow access to all domains .(*在上面一行将允许access to all domains 。) For allowing access to specific domain only :(access to specific domain only允许access to specific domain only ：) response.addHeader("Access-Control-Allow-Origin", "http://www.example.com"); Check this blog post .(查看此blog post 。)
