Appweb配置

Appweb配置

      具体配置网页=>

具体参考源码配置demo：/appweb-6.1.1/test/appweb.conf

      Appweb操作通常由Appweb配置文件(appweb.conf)控制。 这个配置文件是在Appweb启动时读取的，它管理着Appweb配置的各个方面，包括监听什么端口和地址，加载哪些模块，在哪里查找网页以及如何记录请求。

      Appweb也可以通过编程来配置。有关详细信息，请阅读
Appweb AP
I( 
Appweb API
)。

      在appweb启动时读取一次。 对配置文件的更改将需要重新启动Appweb。
另一个配置文件可以通过使用-
-config Appweb命令选项指定。

1. Sample configuration file(简单的示例配置文件)

配置指令是每行一个，对指令名称不区分大小写。以“#”字符开头的行是注释，并被忽略

2.Configuration Blocks（配置块）

一个appweb.conf文件由多种配置选项构成:

● 
Global Directives          (全局指令)

● Route Blocks                (路由块)

● Virtual Host Blocks       (虚拟主机块)

● Include Directives         (Include 指令)

● Conditional Directives  (条件指令)

Ⅰ. Global Directives(全局指令)

      没有被任何选项块包含的选项就是全局选项，定义一些 appweb 的全局属性。

Ⅱ. Route Blocks(路由块)

      Route块定义了应用于特定URL的一组指令。该块是由Route指令创建的
例如
：

        

       它表示以 "/myapp/" 开头的 URL 请求转给 esp 处理。

Ⅲ. Virtual Host Blocks(虚拟主机块)

      虚拟主机块定义了应用于虚拟子服务器的一组指令。虚拟服务器可能与虚拟服务器名称或IP地址相关联。虚拟主机使您能够分割web服务器以服务于不同域或IP地址的唯一内容。

      下面是一个基于ip的虚拟主机的例子：

       

      下面是一个基于名称的虚拟主机的示例：

Virtual Hosting
。

Ⅳ. 
Include Directives(Include 指令)

      include指令允许将其他文件包含在配置文件中。include指令可以是带有通配符的单个文件名或文件名(做用户名密码储存数据库的时候会用到)

       

Ⅴ. Conditional Directives  (条件指令) 

      配置文件通过
指令支持条件处理。if指令测试一个符号值，如果是true，它可以解析嵌套的指令。如果值为false，则会忽略嵌套的指令。
