Scene Description

Users can enable Http2 to communicate and improve performance through simple configuration.

External Service Communication Configuration

The configuration related to external service communication is written in the microservice.yaml file.

• Enable h2(Http2 + TLS) for communication    When configuring the service listening address, the server can enable TLS communication by appending ?sslEnabled=true to the address. For details, see the section [Using TLS Communication] (../../security/tls.md). Then add &protocol=http2 to enable h2 communication. An example is as follows:

  servicecomb:
    rest:
      address: 0.0.0.0:8080?sslEnabled=true&protocol=http2
    highway:
      address: 0.0.0.0:7070?sslEnabled=true&protocol=http2
  

• Enable h2c(Http2 without TLS) for communication    When the server configures the service listening address, the server can enable h2c communication by appending ?protocol=http2 to the address. An example is as follows:

  servicecomb:
    rest:
      address: 0.0.0.0:8080?protocol=http2
    highway:
      address: 0.0.0.0:7070?protocol=http2
  

• The client will communicate using http2 by reading the configuration in the server address from the service center.
