Quick start

It is recommended to use java to define the interface jar first, and use the erlanalysis tool to parse the java interface to Erlang lib

Import dependent libraries

Use the Rebar compilation tool.

Add dubblerl to rebar.config to your project

{deps, [
    {dubboerl, {git, "https://github.com/apache/dubbo-erlang.git", {branch, "master"}}}
]}.

Use erlang.mk compilation tool

in progress...

Import interface library

Suppose the interface lib you exported is called dubbo_service.

• If you didn’t upload your lib to your git repository, It is recommended that you copy the dubbo_service lib into the project’s apps directory.
• If it is uploaded to your git repository, you can import like this:

{deps, [
    {dubboerl, {git, "https://github.com/apache/dubbo-erlang.git", {branch, "master"}}},
    {dubbo_service,{git,"${INTERFACE_LIB_URL}",{branch,"master"}}} %% replace ${INTERFACE_LIB_URL} with your lib git repos url
]}.

Consumer configuration

Please reference Reference Config

Init dubbolib in your project

It is need you

dubboerl:init().

How to call？

Synchronous call

Request = #userInfoRequest{requestId = 123, username = "testname"},
{ok,RequestRef,Response,RpcContent}  = userOperator:queryUserInfo(Request,#{sync=> true}).

If it occur error, is reponse {error,Reason}.

Asynchronous call

Default is Async call.

Request = #userInfoRequest{requestId = 123, username = "testname"},
{ok,RequestRef} = userOperator:queryUserInfo(Request).

%% you can receive the message after.
handle_cast({msg_back,RequestRef,Response,RpcContent},State).
