在C ++中使用NPAPI开发Chrome扩展 [英] Developing Chrome Extensions Using NPAPI in C++

问题描述

我想用C ++开发一个简单的Chrome扩展，使用NPAPI，它可以将当前页面的HTML内容转储到文件上。我在开发插件/扩展方面没有太多的专业知识。 http://code.google.com/chrome/extensions/getstarted.htmlrel =noreferrer> http://code.google.com/chrome/extensions/getstarted.html

<2> - 创建一个NPAPI插件...

3 - 在您的扩展的清单中添加插件...

 plugins：[
 { path：your_npapi_plugin.dll} 
]，
  

4 - 背景页面创建插件

 < script> 
 var plugin = document.getElementById（MyNPAPIPluginId）; 
 ... 
< / script> 
  

5 - 创建一个JavaScript，您将用作每个页面上注入的内容脚本。
在该脚本中与您的npapi脚本对象进行通信并完成您想要完成的工作。

我如何获得MyNPAPIPluginId的值？我所有的就是DLL的名称？

当您添加插件的标签时，在您的背景页面上，将ID

 < embed type =application / my-plugin-mimetypeid =MyNPAPIPluginId> 
  

在Windows上，在DLL的资源文件上添加MIMEType，添加一个条目：

  VALUEMIMEType，application / my-plugin-mimetype
  

I want to develop a simple Chrome extension in C++, using NPAPI, which does the job of dumping the HTML content of the current page onto a file. I don't have much expertise in developing plugins/extensions. How do I get started on this?

解决方案

1 - Create a Extension... http://code.google.com/chrome/extensions/getstarted.html

2 - Create a NPAPI plugin... http://colonelpanic.net/2009/03/building-a-firefox-plugin-part-one/

3 - On the manifest of your extension add the plugin...

"plugins": [
    { "path": "your_npapi_plugin.dll" }    
  ],

4 - On your extension background page create the plugin

<script>
var plugin = document.getElementById("MyNPAPIPluginId");
...
</script>

5 - Create a javascript that you will use as a content script injected on every page. On that script communicate with your npapi scriptable object and do the work you want to do.

How do I get the value of MyNPAPIPluginId? All I have is the name of the DLL?

On your background page when you add the tag of your plugin, you place the id

<embed type="application/my-plugin-mimetype" id="MyNPAPIPluginId">

On Windows you add the MIMEType on the resource file of the DLL, add a entry with:

VALUE "MIMEType", "application/my-plugin-mimetype"
