Chrome Extensions - onRequest/sendRequest vs onMessage/sendMessage
提问by FRD
Checking out this sample extensionlinked by a page in the Chrome Extension center, I see they used
查看Chrome 扩展中心页面链接的这个示例扩展，我看到他们使用了
chrome.extension.onRequest.addListener(onRequest);
in the background.js page in order to listen to the contentscript.js and
在 background.js 页面中以收听 contentscript.js 和
chrome.extension.sendRequest({}, function(response) {});
in the contentscript.js in order to talk to the background.js page.
在 contentscript.js 中，以便与 background.js 页面对话。
But I can't find the documentation for these functions anywhere in the web and Google's Message Passing guideonly mentions
但是我在网络上的任何地方都找不到这些功能的文档，而且谷歌的消息传递指南只提到了
chrome.extension.sendMessage(...)
to send, and
发送，和
chrome.extension.onMessage.addListener(...)
to listen.
听。
Which functions should I use? Is sendRequest/onRequest obsolete? Is the Google's dev guide still up-to-date?
我应该使用哪些功能？sendRequest/onRequest 过时了吗？Google 的开发指南是否仍然是最新的？

It seems sendMessageis favored over sendRequest, which is to be deprecated: http://codereview.chromium.org/9965005/
它似乎sendMessage受到青睐sendRequest，但将被弃用：http: //codereview.chromium.org/9965005/
