从文件系统HTML页面向Chrome扩展名发送消息 [英] Sending messages from file system html page to a chrome extension
问题描述
我是创建Chrome扩展程序的新手.我要测试将网页中的消息发送到扩展程序，如下所述: https://developer.chrome.com/extensions/messaging#external-webpage .
I'm new to creating chrome extensions. I want to test sending messages from a web page to an extension as described here: https://developer.chrome.com/extensions/messaging#external-webpage.
我只想在文件系统中使用html文件(例如"file:///C:/Users/johng/Documents/TestExtensionCall.html")进行初始测试，但开发人员文档指出您需要在扩展程序清单中包括"externally_connectable"以公开消息传递api，并且url模式必须包含第二级域.
I'd like to just use an html file in my file system, like "file:///C:/Users/johng/Documents/TestExtensionCall.html", to do the initial testing but the developer documentation indicates that you need to include "externally_connectable" in your extension manifest to expose the messaging api and the url pattern must include a second-level domain.
文件系统中的html文件可以用于测试从网页向chrome扩展名发送消息的情况吗?我是否真的需要使用网站上的网页进行测试?
Can an html file from the file system be used to test sending messages from a web page to a chrome extension? Do I actually need to use a web page from a web site to do the testing?
谢谢， 约翰
推荐答案
要测试externally_connectable，您需要 1 可以使用Web服务器.
For testing externally_connectable, you have1 to use a web server.
尽管如此，您仍然可以使用本地开发Web服务器.通常，它的主机名是localhost，但是您可以在DNS主机文件中为其指定别名，例如my.localhost，这样就可以满足Chrome的要求.
Though, you can still use a local development web server. Normally, it would have a localhost hostname, but you can specify an alias for it in your DNS hosts file, say, my.localhost, and it would satisfy Chrome's requirements.
有关主机文件的更多信息，请参见此处.
