WSO2 API Manager是否支持gRPC服务？能否发布非OpenAPI服务？

Great question! WSO2 API Manager fully supports publishing and managing gRPC services—you’re not limited to only OpenAPI-based services. Here’s a breakdown of the support and how to leverage it:

Key Support Features #

• Direct gRPC API Creation: You can import your gRPC .proto service definition files directly into the WSO2 AM Publisher portal. The platform auto-generates the necessary API artifacts, and you can even opt to expose a REST/HTTP interface alongside the native gRPC endpoint if you need to support non-gRPC clients.
• Protocol Translation: WSO2 AM includes built-in protocol translation capabilities, letting you convert gRPC requests to REST/HTTP and vice versa. This is super useful if you have mixed client types that don’t all support gRPC natively.
• Full Lifecycle & Governance: Just like any other API, your gRPC APIs get access to WSO2 AM’s complete lifecycle tools—versioning, publishing, deprecation, and retirement. You can also apply standard security policies (OAuth2, JWT, mTLS), rate limiting, throttling, and track usage via analytics.
• Streaming Support: WSO2 AM handles all gRPC streaming types (bidirectional, server-side, client-side) seamlessly, so you don’t have to worry about losing functionality when publishing streaming gRPC services.

Quick Workflow to Publish a gRPC Service #

1. Get your .proto file ready: Make sure your gRPC service definition is in a valid, properly formatted .proto file.
2. Import into WSO2 AM: Head to the API Publisher, click "Import API" > "gRPC API", then upload your .proto file.
3. Configure your API: Set up metadata like name, version, and context, define access policies, and tweak any protocol translation settings if you need them.
4. Publish and share: Once you’re done configuring, publish the API—your consumers can then discover and use it via the Developer Portal.

A Quick Note #

Make sure you’re using a supported version of WSO2 API Manager (versions 3.2.0 and above have solid gRPC support; newer releases like 4.x+ include additional improvements and bug fixes for gRPC handling).
