问题 I need to deploy my node-XMLHttpRequest app to a server that uses a proxy to access the internet. In a terminal on that server, I can curl -d "" http://website/path and it works fine. I think curl recognizes the environment variable http_proxy in that case. The node app times out because it doesn't see the proxy. How can I get the node app to use the proxy? For instance, could I use http.globalAgent to send the requests through the proxy? 回答1: Did you provide the proxy options to the http

问题 I have developed a Google Chrome extensions that uses YouTube Data API v2 . My permission field in the manifest looks like this, because the script is injected in pages under youtube.com and I also need access to tabs: "permissions": ["tabs", "*://*.youtube.com/*"] This also works when I do a request to YouTube Data API v2 because the request is done to http://gdata.youtube.com/, so it is the same domain.

问题 I don't really get Access-Control-Allow-Origin and CORS. If I allow request from any domain to my page, does that imply any security issues for my page? I always thought, that SOP ensures, that there can't run any script on a page, which requests data from another server, as that data might be malicious.

问题 Today, I had to restart my browser due to some issue with an extension. What I found when I restarted it, was that my browser (Chromium) automatically updated to a new version that doesn't allow synchronous AJAX-requests anymore. Quote: Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/. I need synchronous AJAX-requests for my node.js applications to work though, as they

问题 I'm working with an API which needs extra security information sent along with an HTTP request as meta-information in headers.
