统一资源标志符方案

在计算机科学， URI方案是统一资源标志符 (URI)命名结构的第一级。所有的统一资源定位符是从模式名称后跟两个点构建的（“:”）构建的。对句法和语义的具体一部分，在很大程度上，留给不同的技术规范。

由于大多数模式最初设计用于协议，因此它们通常被错误地称为“协议”或“URI协议”。例如，超文本传输协定方案通常用于使用超文本传输协定协议指定网络资源。现在，此模式中的URI用于其他应用程序，例如与协议无关的资源描述框架资源（请参阅资源描述框架方案）或XML的命名空间。

移动深度连结是一类非官方URI方案例子。

## 通用的语法

```
`<方案名稱>:<等級部分>[吗？ <查询>][#<片段>]`
```

### 例子

以下是URI的两个示例及其不同的组件：

```
  foo://username:password@example.com:8042/over/there/index.dtb?type=animal;name=ferret#nose
  \ /   \________________/\_________/ \__/            \___/ \_/ \_____________________/ \__/
   |           |               |       |                |    |           |                |
   |          用戶            主機    端口              |    |          查詢             片段
   |    \_______________________________/ \_____________|____|/
  方案                  |                         |     |    |
   |                   域名                      路徑   |    |
   |                                                    |    |
   |             路徑                              可以解釋為文件名
   |   ___________|____________                              |
  / \ /                        \                             |
  urn:example:animal:ferrett:nose                  可以解釋為擴展名
```
