Go-zero api example

This example uses go-zero's built-in OpenTelemetry support to export traces to Uptrace.

Step 1. Create an Uptrace project to obtain a DSN, then edit etc/api-api.yaml and put your DSN into OtlpHeaders.uptrace-dsn:

Telemetry:
  Name: api-api
  Sampler: 1.0
  Batcher: otlphttp
  Endpoint: api.uptrace.dev
  OtlpHttpPath: /v1/traces
  OtlpHttpSecure: true
  OtlpHeaders:
    uptrace-dsn: https://<token>@api.uptrace.dev/<project_id>

Note. We use the otlphttp batcher because go-zero's otlpgrpc batcher always dials insecurely and therefore can't reach Uptrace Cloud over TLS. If you run a local Uptrace stack you may instead use Batcher: otlpgrpc with Endpoint: localhost:14317.

Step 2. Start the go-zero server:

go run api.go -f etc/api-api.yaml

Step 3. Open http://localhost:8888/from/you to trigger a request.

Step 4. Open the Uptrace UI to view the trace.
