//同步方法 app.MapGet("/sync", () => { using (var con = new MySqlConnection(connectionString)) { var result = con.Query<int>("select sleep(6)"); Console.WriteLine($"sync:{DateTime.Now}"); return result; } }); //异步方法,没有CancellationToken app.MapGet("/async", async () => { using (var con = new MySqlConnection(connectionString)) { var result = await con.QueryAsync<int>("select sleep(6)"); Console.WriteLine($"sync:{DateTime.Now}"); return result; } }); //异步,有CancellationToken app.MapGet("/asyncwithtoken", async (CancellationToken token) => { using (var con = new MySqlConnection(connectionString)) { var result = await con.QueryAsync<int>(new CommandDefinition("select sleep(6)", cancellationToken: token)); Console.WriteLine($"sync:{DateTime.Now}"); return result; } });通过postman请求三个api,然后取消,会发现前两个api始终会执行完成,并输出时间;第三个会在取消后停止响应。
