Quick Start

It is recommended to first define the interface jar using Java, and use the erlanalysis tool to parse Java interfaces into Erlang lib.

Import Dependency Libraries

Using the Rebar Build Tool.

Add dubblerl to your project’s rebar.config

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

Using the erlang.mk Build Tool

To be added

Import Interface Libraries

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 it 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 repo URL
]}.

Consumer Configuration

Please reference Reference Config

Init dubbolib in Your Project

It is need you to

dubboerl:init().

How to Call?

Synchronous Call

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

If an error occurs, the response is {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).
