+## Dubbo Proxy
+[中文版本](README_zh.md)
+Dubbo Proxy, a gateway of Dubbo, switch from HTTP request to Dubbo protocol，then invoke Dubbo service and return to the result. Later Dubbo Proxy would combine several features, including circuit breaker, current-limiting, api management.
+
+
+### instructions
+
+HTTP request format:
+
+```
+{application Name}/{Interface name}?version={version}&group={group}
+```
+Group and version is the mapping data in Dubbo service.
+
+http POST body:
+
+```json
+{
+ "methodName" : "sayHello",
+ "paramTypes" : ["org.apache.dubbo.demo.model.User"],
+ "paramValues": [
+ {
+ "id": 23,
+ "username": "fwjoifjwie"
+ }
+ ]
+}
+```
+
+* In the Dubbo 2.7 version and later updates versions, paramTypes is optional data, if not filled in, Dubbo Proxy would get related mapping data from metadata center.
+* You can set registry address and metadata center address in `application.yml`
+```
+proxy.registry.address: zookeeper://127.0.0.1:2181 #registry center address, same as Dubbo service's
+proxy.metadata-report.address: zookeeper://127.0.0.1:2181 #metadata center address, used by paramType search, support for dubbo 2.7 or later
+```

+### Dubbo Proxy
+[English Version](README.md)
+Dubbo Proxy是一个Dubbo网关，可以将Http请求转换成Dubbo的协议，调用Dubbo服务并且返回结果，后续还会集成熔断，限流，api管理等功能。
+
+### 用法
+http请求格式如下：
+```
+POST {application Name}/{Interface name}?version={version}&group={group}
+```
+其中group和version是Dubbo服务对应的group和version，为可选参数
+
+http POST body如下:
+
+```json
+{
+ "methodName" : "sayHello",
+ "paramTypes" : ["org.apache.dubbo.demo.model.User"],
+ "paramValues": [
+ {
+ "id": 23,
+ "username": "fwjoifjwie"
+ }
+ ]
+}
+```
+
+* 在Dubbo 2.7及后续版本中，paramTypes为可选，如果不填写，Dubbo Proxy会在元数据中心获取对应的参数类型。
+* 可以在`application.yml`中指定注册中心和元数据中心的地址
+```
+proxy.registry.address: zookeeper://127.0.0.1:2181 #注册中心地址，和Dubbo服务的注册中心相同
+proxy.metadata-report.address: zookeeper://127.0.0.1:2181 #元数据中心的地址，未指定paramTypes时查找使用，支持Dubbo 2.7及以后版本
+```
