| ## Description |
| |
| Routes match the client's request based on defined rules, load and execute the corresponding [plugins](./plugin.md), and forwards the request to the specified [Upstream](./upstream.md). |
| |
| A Route mainly consists of three parts: |
| |
| 1. Matching rules (`uri`, `host`, `remote address`) |
| 2. Plugin configuration (current-limit, rate-limit) |
| 3. Upstream information |
| |
| The image below shows some example Route rules. Note that the values are of the same color if they are identical. |
| |
|  |
| |
| All the parameters are configured directly in the Route. It is easy to set up, and each Route has a high degree of freedom. |
| |
| When Routes have repetitive configurations (say, enabling the same plugin configuration or Upstream information), to update it, we need to traverse all the Routes and modify them. This adds a lot of complexity, making it difficult to maintain. |
| |
| These shortcomings are independently abstracted in APISIX by two concepts: [Service](service.md) and [Upstream](upstream.md). |
| |
| ## Example |
| |
| The Route example shown below proxies the request with the URL `/index.html` to the Upstream service with the address `127.0.0.1:1980`. |
| |
| :::note |
| You can fetch the `admin_key` from `config.yaml` and save to an environment variable with the following command: |
| |
| ```bash |
| admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g') |
| ``` |
| |
| ::: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 \ |
| -H "X-API-KEY: $admin_key" -X PUT -i -d ' |
| { |
| "uri": "/index.html", |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "127.0.0.1:1980": 1 |
| } |
| } |
| }' |
| ``` |
| |
| ```shell |
| HTTP/1.1 201 Created |
| Date: Sat, 31 Aug 2019 01:17:15 GMT |
| Content-Type: text/plain |
| Transfer-Encoding: chunked |
| Connection: keep-alive |
| Server: APISIX web server |
| |
| {"node":{"value":{"uri":"\/index.html","upstream":{"nodes":{"127.0.0.1:1980":1},"type":"roundrobin"}},"createdIndex":61925,"key":"\/apisix\/routes\/1","modifiedIndex":61925}} |
| ``` |
| |
| A successful response indicates that the route was created. |
| |
| ## Configuration |
