We also tried nw.js (Formerly known as Node-Webkit) and we had no problem making cross domain ajax call with it. Is Atom Shell (Electron) restricts cross domain calls by default ? 回答1: If the webpage is loaded in "file://" mode and not served by an http server, you can make ajax calls by default. If you still have troubles with CORS restrictions, you can

It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed.

Anyone can give me a link to explain this ? 回答1: TL;DR The DACR not only decreases the context switch code path, but can also speed execution after the context switch occurs. There are several links which explain the specifics of Domain Access Control Register or DACR . For example ARM's Memory access permissions and domains . However, this page and many others don't explain why you might need this feature;

Is there some way to get this to work in IE7? Unfortunately, I cannot use a server side proxy for security reasons. Perhaps using an iFrame? I forgot to mention, but I control the other server also. 回答1: The Easy XDM library was developed to solve the cross origin problem : easyXDM is a Javascript library that enables you as a developer to easily work around the limitation set in place by the Same

Here is my code: from math import sqrt def distance(x1,y1,x2,y2): x3 = x2-x1 xFinal = x3^2 y3 = y2-y1 yFinal = y3^2 final = xFinal + yFinal d = sqrt(final) return d 回答1: Your issue is that exponentiation in Python is done using a ** b and not a ^ b ( ^ is bitwise XOR) which causes final to be a negative value, which causes a domain error. Your fixed code: def distance(x1, y1, x2, y2): return ((x2 - x1) ** 2 + (y2 - y1) ** 2) ** .5 # to

It will be a virtual domain that just like my actual domain except for one difference: it will only serve files that end in .jpg .jpeg .gif .png etc. This way I can refer to img.mydomain.com/some_image.jpg. it will speed up the page speed by making the browser think that it's two separate domains (google page speed analyzer is always nagging me to do this). I'm running apache on a linux server. Should I do this in httpd.conf? If so, what is my first step? 回答1: create 2 folder for each

Suppose I want to get a page outside my domain using jQuery AJAX: $.get('http://www.domain.com/mypage.html', function(data) { alert(data); }); I will probably get this error message: XMLHttpRequest cannot load http://www.domain.com/path/filename . Origin null is not allowed by Access-Control-Allow-Origin. we can't load cross domain page using AJAX because of the Same-origin policy .

Every thing works fine until more than one app domain not come into play like NUnit or WCF hosting i.e. with one app domain. I have stored managed object in gcroot in cli for callback. I have read that this is the root cause of app domain issue ("Cannot pass a GCHandle across AppDomains") because they don't have app domain info ( http://lambert.geek.nz/2007/05/29/unmanaged-appdomain-callback/ ). someone suggested to
