-The tRPC framework uses PB to define services, but providing REST-style APIs based on the HTTP protocol is still a widespread demand. Unifying RPC and REST is not an easy task. The HTTP RPC protocol of the tRPC-Go framework hopes to define the same set of PB files, so that services can be called through both RPC (i.e., through the NewXXXClientProxy provided by the stub code) and native HTTP requests. However, such HTTP calls do not comply with RESTful specifications, for example, custom routes cannot be defined, wildcards are not supported, and the response body is empty when errors occur (error information can only be put into the response header). Therefore, we additionally support RESTful protocols, and no longer try to forcibly unify RPC and REST. If the service is specified as RESTful, it is not supported to call it with stub code, but only supports http client call. The benefits of doing so are that you can provide API that complies with the RESTful specifications through protobuf annotation in the same set of PB files, and can use various plugins and filter capabilities of the tRPC framework. - -## Usage - -- Define a PB file that contains the service definition and RESTful annotations. -```protobuf -// file : examples/features/restful/server/pb/helloworld.proto -// Greeter service -service Greeter { - rpc SayHello(HelloRequest) returns (HelloReply) { - option (trpc.api.http) = { - // http method is GET and path is /v1/greeter/hello/{name} - // {name} is a path parameter , it will be mapped to HelloRequest.name - get: "/v1/greeter/hello/{name}" - }; - } - ............ - ............ -} -``` - -- Generate the stub code. -```shell -trpc create -p helloworld.proto --rpconly --gotag --alias -f -o=. -``` - -- Implement the service. -```go -// file : examples/features/restful/server/main.go -type greeterService struct{ - pb.UnimplementedGreeter -} - -func (g greeterService) SayHello(ctx context.Context, req *pb.HelloRequest) (*pb.HelloReply, error) { - log.InfoContextf(ctx, "[restful] Received SayHello request with req: %v", req) - // handle request - rsp := &pb.HelloReply{ - Message: "[restful] SayHello Hello " + req.Name, - } - return rsp, nil -} -``` - -- Register the service. -```go -// file : examples/features/restful/server/main.go -// Register Greeter service -pb.RegisterGreeterService(server, new(greeterService)) -``` - -- config -```yaml -# file : examples/features/restful/server/trpc_go.yaml -server: # server configuration. - app: test # business application name. - server: helloworld # service process name. - bin_path: /usr/local/trpc/bin/ # paths to binary executables and framework configuration files. - conf_path: /usr/local/trpc/conf/ # paths to business configuration files. - data_path: /usr/local/trpc/data/ # paths to business data files. - service: # business service configuration，can have multiple. - - name: trpc.test.helloworld.Greeter # the route name of the service. - ip: 127.0.0.1 # the service listening ip address, can use the placeholder ${ip}, choose one of ip and nic, priority ip. - port: 9092 # the service listening port, can use the placeholder ${port}. - network: tcp # the service listening network type, tcp or udp. - protocol: restful # application layer protocol.

Typically, a process contains a server, and each server can contain one or more logical services. -A service process may listen on multiple ports, providing different business services on different ports. Therefore, the server package introduces the concepts of `Server`, `Service`, and `Proto service`. Typically, one process contains one `Server`, and each `Server` can contain one or more `Service`. `Services` are used for name registration, and clients use it's names for routing and sending network requests. Upon receiving a request, the server executes the business logic based on the specified `Protos service`. +This design of the server can support the application scenarios of multiple port protocols very well. It is convenient in scenarios such as compatibility with legacy business protocol frameworks, providing additional HTTP protocols for web calls through other ports, etc. -- `Server`: Represents a tRPC server instance, i.e., one process. -- `Service`: Represents a logical service, i.e., a real external service that listens on a port. It corresponds one-to-one with services defined in the configuration file, with one `Server` possibly containing multiple `Service`, one for each port. -- `Proto service`: Represents a protocol service defined in a protobuf protocol file. Typically, a `Service` corresponds one-to-one with a `Proto service`, but users can also combine them arbitrarily using the `Register` method. +The multiple services in pb are actually used to logically group multiple interfaces. With the ability of tRPC-Go to support multiple services, finer-grained control of interfaces can be achieved by isolating interfaces on ports in the future. -```golang -// Server is a tRPC server.

-tRPC streaming is divided into three types: - -- Server-side streaming RPC -- Client-side streaming RPC -- Bidirectional streaming RPC - -Why do we need streaming? Are there any issues with Simple RPC? When using Simple RPC, the following issues may arise: - -- Instantaneous pressure caused by large data packets. -- When receiving data packets, all packets must be received correctly before the response is received and business processing can take place (it is not possible to receive and process data on the client and server simultaneously). - -Why use Streaming RPC: - -- With Simple RPC, for large data packets such as a large file that needs to be transmitted, the packets must be manually divided and reassembled, and any issues with packets arriving out of order must be resolved. In contrast, with streaming, the client can read the file and transmit it directly without the need to split the file into packets or worry about packet order. -- n real-time scenarios such as multi-person chat rooms, the server must push real-time messages to multiple clients upon receiving a message. - -## Principle - -See [here](https://github.com/trpc-group/trpc/blob/main/docs/cn/trpc_protocol_design.md) for the tRPC streaming design principle. - -## Example - -### Client-side streaming - -#### Define the protocol file +## Server call mode ```protobuf syntax = "proto3";

During tRPC stream initialization, the window size is sent to the receiver. -- After receiving the initial window size, the receiver records it locally. For each DATA frame sent by the sender, the sender subtracts the size of the payload (excluding the frame header) from the current window size. -- If the available window size becomes less than 0 during this process, the sender cannot send the frame without splitting it (unlike HTTP2.0) and the upper layer API becomes blocked. -- After consuming 1/4 of the initial window size, the receiver sends feedback in the form of a feedback frame, carrying an incremental window size. After receiving the incremental window size, the sender adds it to the current available window size. -- For frame priority, feedback frames are given higher priority than data frames to prevent blocking due to priority issues. - -Flow control is enabled by default, with a default window size of 65535. If the sender continuously sends data larger than 65535 (after serialization and compression), and the receiver does not call Recv, the sender will block.

Only synchronous mode can be used. This is because streams only support synchronous mode. Therefore, if you want to use asynchronous mode, you must define a service with only ordinary RPC methods. - -### The streaming client must use `err == io.EOF` to determine the end of the stream - -It is recommended to use `err == io.EOF` to determine the end of a stream instead of `errors.Is(err, io.EOF)`. This is because the underlying connection may return `io.EOF` after disconnection, which will be encapsulated by the framework and returned to the business layer. If the business layer uses `errors.Is(err, io.EOF)` and receives a true value, it may mistakenly believe that the stream has been closed properly, when in fact the underlying connection has been disconnected and the stream has ended abnormally. -
