Scenario

Users can easily enable Http2 protocol for better performance through configuration.

External Service Communication Configuration

The configuration for external service communication is in the microservice.yaml file.

• Enable h2(Http2 + TLS)

  Append ?sslEnabled=true to the listening address to enable TLS communication on server side. For details, see the section Using TLS Communication. Then add &protocol=http2 to enable h2 communication. Here is the sample configuration:

  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)

  Simply add ?protocol=http2 to enable h2c communication in the server's configuration:

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

• The client will read the server's address configuration from service center, then communicate with the server by http2 protocol.
