HTTP/2 和 gRPC，原生运行于 Delphi

uses
  sgcHTTP;
var
  HTTP2: TsgcHTTP2Client;
begin
  // HTTP/2: multiplexed requests over one TLS connection
  HTTP2 := TsgcHTTP2Client.Create(nil);
  HTTP2.Host := 'https://api.example.com';

  HTTP2.Active := True;

  HTTP2.GetAsync('/v1/status');
end;

  const Connection: TsgcHTTP2ConnectionClient;
  const Request: TsgcHTTP2RequestProperty;
  const Response: TsgcHTTP2ResponseProperty);
begin
  Memo1.Lines.Add(Response.DataString);
end;

uses
  sgcHTTP;
var
  GRPC: TsgcGRPCClient;
begin
  // gRPC: built on the HTTP/2 client, unary and streaming RPC
  GRPC := TsgcGRPCClient.Create(nil);
  GRPC.Client.Host := 'https://grpc.example.com';
  GRPC.OnGRPCResponse := GRPCResponse;

  GRPC.CallAsync('example.OrderService', 'GetOrder', RequestBytes);
end;

  const aResponse: TsgcGRPCResponse);
begin
  Memo1.Lines.Add(aResponse.DataString);
end;
