Wiki

Convert an incoming JSON (or a different one in the future) request from AUTH service and convert it into GRPC request and send it to ROUTER service.

Technologies

Service uses next technologies:

• SocketIO client (for connect to a config service and receive config)

Features

• Now just convert a request from JSON to GRPC formats.
• Every incoming request must start with /api prefix.
• After it there is a GRPC connection pool to ROUTER service and create a new GRPC request of type google.protobuf.Struct. Information about requested method packed into GRPC header with key proxy_method_name. All authorization headers start with x- also packs into headers with the same names. Eventually, the request sends to ROUTING service BackendService.Request.
• TODO. To have abilities to accept an incoming request in different formats (GRPC, XML, etc.).
• TODO. To have abilities to return a response in different formats (GRPC, XML, etc.).
• TODO. To have abilities to balance proxying further request at different ROUTING service with different algorithms.
