Delphi mORMot无法连接，因为目标机器主动拒绝它

Question

我测试mORMot组件。我编写了standart演示"28 -简单的RESTful ORM“，运行它并得到一个错误。

代码：

var
  aModel: TSQLModel;
  aProps: TSQLDBConnectionProperties;
  aRestServer: TSQLRestServerDB;
  aHttpServer: TSQLHttpServer;
begin
// set logging abilities
SQLite3Log.Family.Level := LOG_VERBOSE;
//SQLite3Log.Family.EchoToConsole := LOG_VERBOSE;
SQLite3Log.Family.PerThreadLog := ptIdentifiedInOnFile;
// ODBC driver e.g. from http://ftp.postgresql.org/pub/odbc/versions/msi


aProps := TODBCConnectionProperties.Create('','Driver=PostgreSQL Unicode'+
  {$ifdef CPU64}'(x64)'+{$endif}';Database=postgres;'+
  'Server=127.0.0.1;Port=5433;UID=postgres;Pwd=postgres','','');

//readln;

try
// get the shared data model
aModel := DataModel;
// use PostgreSQL database for all tables
VirtualTableExternalRegisterAll(aModel,aProps);
try
  // create the main mORMot server
  aRestServer := TSQLRestServerDB.Create(aModel,':memory:',false); // authentication=false
  try
    // optionally execute all PostgreSQL requests in a single thread
    aRestServer.AcquireExecutionMode[execORMGet] := amBackgroundORMSharedThread;
    aRestServer.AcquireExecutionMode[execORMWrite] := amBackgroundORMSharedThread;
    // create tables or fields if missing
    aRestServer.CreateMissingTables;
    // serve aRestServer data over HTTP
    aHttpServer := TSQLHttpServer.Create(SERVER_PORT,[aRestServer],'+',useHttpApiRegisteringURI);
    try
      aHttpServer.AccessControlAllowOrigin := '*'; // allow cross-site AJAX queries
      writeln('Background server is running.'#10);
      write('Press [Enter] to close the server.');
      readln;
    finally
      aHttpServer.Free;
    end;
  finally
    aRestServer.Free;
  end;
finally
  aModel.Free;
end;
finally
  aProps.Free;
end;
end.

错误

{“消息”：“TODBCLib错误: 08001无法连接到服务器；\n由于目标计算机主动拒绝连接而无法连接。\r 127.0.0.1:5433

如何清除它。

Answer 1

我刚刚用Delphi西雅图10和来自0400.zip的ODBC驱动程序测试了它--没有问题。

确保您的PostgreSQL服务器已定义为运行在源所期望的相同端口上。如果使用默认端口号，则将5433值编辑为5432。

由于偏执，我总是试图更改默认端口，这减少了网络扫描攻击(至少从快速扫描)。我从不对ssh使用端口22，对PostgreSQL使用端口5432。很抱歉给您带来不便。
