change getRawParameter to getParameter because group never appears in special meta information
```java
public String getRawParameter(String key) {
if ("protocol".equals(key))
return protocol;
if ("username".equals(key))
return username;
if ("password".equals(key))
return password;
if ("host".equals(key))
return host;
if ("port".equals(key))
return String.valueOf(port);
if ("path".equals(key))
return path;
return getParameter(key);
}
```
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.
HTTP request format:
{application Name}/{Interface name}?version={version}&group={group}
Group and version is the mapping data in Dubbo service.
http POST body:
{ "methodName" : "sayHello", "paramTypes" : ["org.apache.dubbo.demo.model.User"], "paramValues": [ { "id": 23, "username": "testUser" } ] }
application.ymlproxy.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
