how to allow ACCESS-CONTROL-ALLOW-ORIGIN aka cross-domain on wampserver

问题

XMLHttpRequest cannot load https://webservice.com?param=hahah. Origin http://{domain} is not allowed by Access-Control-Allow-Origin.

I get this when I try to make a webservice call through wampserver, how could I enable this on wampserver?

or how may i just jsonP to obtain xml data without javascript throwing an error.

You have to enable the headers module first, like so :

• click on the wamp icon in your systray
• go to Apache > Apache modules
• check the option 'headers_module'

And then include this in your apache config:

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin: *
</IfModule>

(in httpd.conf or in the configuration of your vhost)

(Instead of the * you can also specify a specific domain)

Hope this will solve your problem -

To add the CORS authorization to the header using Apache, simply add the following line inside either the , , or sections of your server config (usually located in a *.conf file, such as httpd.conf or apache.conf), or within a .htaccess file:

For all requests -

Header set Access-Control-Allow-Origin "*"

For trusted hosts -

Header set Access-Control-Allow-Origin "your-ip/domain-here"
