API
RPC(remote procedure call)
- disadvantages
- coupling
- clients needs to know the request procedure names
- advantages
- more freedoms to define any requests.
- examples: <https://api.slack.com/methods>
Restful /Representational State Transfer
- Easy to cache
- every url represent a resource
- disadvantages some special method is hard to use restful to name it. like /login, /resetpassword
- examples [https://developer.github.com/v3/](https://developer.github.com/v3/)
- methods
- GET
- POST
- PUT
- DELETE
GraphQL
It Can allows you to define fields you want to have.
gRPC
- protocol buffers
// The greeter service definition.
service Greeter {
// Sends a greeting
rpc SayHello (HelloRequest) returns (HelloReply) {}
}
// The request message containing the user's name.
message HelloRequest {
string name = 1;
}
// The response message containing the greetings
message HelloReply {
string message = 1;
}
- A opensource remote procedure call framework based on HTTP2 and protobuf
- advantages
- baed on HTTP2, better performance
- call remote like local method, and support multiple language
- protobuf serialization and deserialization is faster than JSON
JSON-RPC
It's a little bit similar with gRPC one, but you define the action method in the JSON request body.
POST /api
{
"jsonrpc": "2.0",
"method": "subtract",
"params": [42, 23],
"id": 1
}

Open API
The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for REST APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service. Open API can be described in yaml or json
Use cases
- Interactive documentation
- Mock server generation
- Client code generation
- Automation testing
