gitbook-plugin-changyan

A comment hosting service for Web sites and online communities that uses a networked platform.

畅言平台的gitbook插件，给gitbook集成评论功能

how to install

旧版本需要安装到gitbook所在目录，如果build时提示无法找到插件，可能是由于使用了nvm或n之类的模块所致，请将插件安装到gitbook模块所在的目录

npm install gitbook-plugin-changyan -g

gitbook 3.0在book.json中添加完插件依赖以后可以直接运行下面的命令进行安装

gitbook install

how to use

Add config in book.json, the config will be changyan object as a global variable.

在book.json中添加设置，属性名为changyan

{
    "plugins": [
        "changyan"
    ],
    "pluginsConfig": {
        "changyan": {
            "appid": "your changyan's appid",
            "conf": "the conf in the code generate by changyan"
        }
    }
}

how to work

Load comment elements when gitbook's page.change event triggered.

由于gitbook特殊的页面加载方式，动态加载评论框的方法

urls like /a/b/

Sometimes a page can have different urls.

www.example.com/ and www.example.com/index.html refer to the same page.

Add some code to process these situation,the procedure to generate unique page id is:

1. get the location.pathname from browser
2. replace all the '/' with '-'
3. if the last char of the result string is '-',append 'index.html' to it(eg: /a/b/ will be cast to -a-b-,final result is -a-b-index.html).

为了处理同一个页面有不同的url的情况，要求一个单独的id来分辨页面。

www.example.com/ 和 www.example.com/index.html 是同一个页面，应该显示相同的评论。

为了兼容这种情况，插件生成惟一id的过程如下：

1. 从location.pathname 中获取url
2. 替换'/'为'-'
3. 如果最后一个字符为-，在末尾添加'index.html'。（/a/b/ 会被转换为 -a-b-，再加上index.html即为最后的id）
