Route 字面意思就是路由，通过定义一些规则来匹配客户端的请求，然后根据匹配结果加载并执行相应的
插件，并把请求转发给到指定 Upstream。

Route 中主要包含三部分内容：匹配规则(比如 uri、host、remote_addr 等)，插件配置(限流限速等)和上游信息。
请看下图示例，是一些 Route 规则的实例，当某些属性值相同时，图中用相同颜色标识。

![路由示例](../../../assets/images/routes-example.png)

我们直接在 Route 中完成所有参数的配置，优点是容易设置，每个 Route 都相对独立自由度比较高。但当我们的 Route 有比较多的重复配置（比如启用相同的插件配置或上游信息），一旦我们要更新这些相同属性时，就需要遍历所有 Route 并进行修改，给后期管理维护增加不少复杂度。

上面提及重复的缺点在 APISIX 中独立抽象了 [Service](service.md) 和 [Upstream](upstream.md) 两个概念来解决。

下面创建的 Route 示例，是把 URL 为 "/index.html" 的请求代理到地址为 "39.97.63.215:80" 的 Upstream 服务：

```shell
$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "39.97.63.215:80": 1
        }
    }
}'

```

当我们接收到成功应答，表示该 Route 已成功创建。
