+## Route
+
+*地址*:/apisix/admin/routes/{id}?ttl=0
+
+*说明*: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。
+
+> 请求方法:
+
+|名字      |请求 uri|请求 body|说明        |
+|---------|-------------------------|--|------|
+|GET      |/apisix/admin/routes/{id}|无|获取资源|
+|PUT      |/apisix/admin/routes/{id}|{...}|根据 id 创建资源|
+|POST     |/apisix/admin/routes     |{...}|创建资源,id 由后台服务自动生成|
+|DELETE   |/apisix/admin/routes/{id}|无|删除资源|
+|PATCH    |/apisix/admin/routes/{id}/{path}|{...}|修改已有 Route 的部分内容,其他不涉及部分会原样保留。|
+
+> uri 请求参数:
+
+|名字      |可选项   |类型 |说明        |示例|
+|---------|---------|----|-----------|----|
+|ttl     |可选 |辅助   |超过这个时间会被自动删除,单位:秒|ttl=1|
+
+> body 请求参数:
+
+|名字      |可选项   |类型 |说明        |示例|
+|---------|---------|----|-----------|----|
+|desc     |可选 |辅助   |标识路由名称、使用场景等。|客户 xxxx|
+|uri      |必须 |匹配规则|除了如 `/foo/bar`、`/foo/gloo` 这种全量匹配外,使用不同 [Router](architecture-design-cn.md#router) 还允许更高级匹配,更多见 [Router](architecture-design-cn.md#router)。|"/hello"|
+|host     |可选 |匹配规则|当前请求域名,比如 `foo.com`;也支持泛域名,比如 `*.foo.com`。|"foo.com"|
+|hosts    |可选 |匹配规则|列表形态的 `host`,表示允许有多个不同 `host`,匹配其中任意一个即可。|{"foo.com", "*.bar.com"}|
+|remote_addr|可选 |匹配规则|客户端请求 IP 地址: `192.168.1.101`、`192.168.1.102` 以及 CIDR 格式的支持 `192.168.1.0/24`。特别的,APISIX 也完整支持 IPv6 地址匹配:`::1`,`fe80::1`, `fe80::1/64` 等。|"192.168.1.0/24"|
+|remote_addrs|可选 |匹配规则|列表形态的 `remote_addr`,表示允许有多个不同 IP 地址,符合其中任意一个即可。|{"127.0.0.1", "192.0.0.0/8", "::1"}|
+|methods  |可选 |匹配规则|如果为空或没有该选项,代表没有任何 `method` 限制,也可以是一个或多个的组合:`GET`, `POST`, `PUT`, `DELETE`, `PATCH`, `HEAD`, `OPTIONS`,`CONNECT`,`TRACE`。|{"GET", "POST"}|
+|vars       |可选  |匹配规则(仅支持 `radixtree` 路由)|由一个或多个`{var, operator, val}`元素组成的列表,类似这样:`{{var, operator, val}, {var, operator, val}, ...}`。例如:`{"arg_name", "==", "json"}`,表示当前请求参数 `name` 是 `json`。这里的 `var` 与 Nginx 内部自身变量命名是保持一致,所以也可以使用 `request_uri`、`host` 等;对于 `operator` 部分,目前已支持的运算符有 `==`、`~=`、`>`、`<` 和 `~~`。对于`>`和`<`两个运算符,会把结果先转换成 number 然后再做比较。查看支持的[运算符列表](#运算符列表)|{{"arg_name", "==", "json"}, {"arg_age", ">", 18}}|
+|filter_func|可选|匹配规则|用户自定义的过滤函数。可以使用它来实现特殊场景的匹配要求实现。该函数默认接受一个名为 vars 的输入参数,可以用它来获取 Nginx 变量。|function(vars) return vars["arg_name"] == "json" end|
+|plugins  |可选 |Plugin|详见 [Plugin](architecture-design-cn.md#plugin) ||
+|upstream |可选 |Upstream|启用的 Upstream 配置,详见 [Upstream](architecture-design-cn.md#upstream)||
+|upstream_id|可选 |Upstream|启用的 upstream id,详见 [Upstream](architecture-design-cn.md#upstream)||
+|service_id|可选 |Service|绑定的 Service 配置,详见 [Service](architecture-design-cn.md#service)||
+|service_protocol|可选|上游协议类型|只可以是 "grpc", "http" 二选一。|默认 "http",使用gRPC proxy 或gRPC transcode 时,必须用"grpc"|
+
+对于同一类参数比如 `host` 与 `hosts`,`remote_addr` 与 `remote_addrs`,是不能同时存在,二者只能选择其一。如果同时启用,接口会报错。
+
+示例:
+
+```shell
+# 创建一个路由
+$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -i -d '
+{
+    "uri": "/index.html",
+    "hosts": ["foo.com", "*.bar.com"],
+    "remote_addrs": ["127.0.0.0/8"],
+    "methods": ["PUT", "GET"],
+    "upstream": {
+        "type": "roundrobin",
+        "nodes": {
+            "39.97.63.215:80": 1
+        }
+    }
+}'
+
+HTTP/1.1 201 Created
+Date: Sat, 31 Aug 2019 01:17:15 GMT
+...
+
+# 创建一个有效期为 60 秒的路由,过期后自动删除
+$ curl http://127.0.0.1:9080/apisix/admin/routes/2?ttl=60 -X PUT -i -d '
+{
+    "uri": "/aa/index.html",
+    "upstream": {
+        "type": "roundrobin",
+        "nodes": {
+            "39.97.63.215:80": 1
+        }
+    }
+}'
+
+HTTP/1.1 201 Created
+Date: Sat, 31 Aug 2019 01:17:15 GMT
+...
+
+```
+
+> 应答参数
+
+目前是直接返回与 etcd 交互后的结果。
+
+### 运算符列表
+
+|运算符   |描述       |例子|
+|--------|-----------|-------|
+|==      |相等      |{"arg_name", "==", "json"}|
+|~=      |不等于    |{"arg_name", "~=", "json"}|
+|>       |大于      |{"arg_age", ">", 24}|
+|<       |小于      |{"arg_age", "<", 24}|
+|~~      |正则匹配   |{"arg_name", "~~", "[a-z]+"}|
+
+请看下面例子,匹配请求参数 name 等于 json ,age 大于 18 且 address 开头是 China 的请求:
+
+```shell
+curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -i -d '
+{
+    "uri": "/index.html",
+    "vars": [
+        ["arg_name", "==", "json"],
+        ["arg_age", ">", "18"],
+        ["arg_address", "~~", "China.*"]
+    ],
+    "upstream": {
+        "type": "roundrobin",
+        "nodes": {
+            "39.97.63.215:80": 1
+        }
+    }
+}'
+```
