中文 🇨🇳

Apache Dubbo-go, a Dubbo implementation written in Golang, is born to bridge the gap between Java/Dubbo and Go/X. Please visit our Dubbo official website for the quick start and documentation.

RPC invocation

Dubbo-go has supported many RPC protocols, like Triple, Dubbo, JSONRPC, gRPC, HTTP, HTTP2. The Triple, Dubbo and gRPC protocols supported security connections via TLS.

  • Triple is the supported protocol of Dubbo3 ecology, and is gRPC extended protocol based on HTTP2, which is compatible with gRPC service.In other words, on the basis of gRPC's reliable invocation, it adds Dubbo's service governance capability.
  • Dubbo protocol is tradition Dubbo ecology protocol, which is compatible with Dubbo 2.x, and is a good choice for cross-language invocation between GO and Java legacy service.
  • HTTP support: As you can see in the figure above, you can invoke Triple/Dubbo service using HTTP protocol through dubbo-go-pixiu gateway.

Service governance capability

Getting started

Tools

  • imports-formatter formatting dubbo-go project import code block.
  • dubbo-go-cli dubbo-go command line tools, by which you can define your own request pkg and gets rsp struct of your server, test your service as telnet and generate hessian.POJO register method body.
  • dubbo-go-cli-v2 new dubbo-go line tools, you can get services from register center, create a demo , create application templates, one-click installation of protoc-gen-go-triple and imports-formatter tools,and has the same features with dubbo-go-cli.
  • protoc-gen-go-triple tripe protocol pb file generation tool.
  • protoc-gen-dubbo3grpc dubbo3 grpc pb file generation tool.

If you want to know more about dubbogo tools, please visit https://github.com/apache/dubbo-go/blob/master/dubbogo-cli and read its readme carefully.
