嗨,我需要有关如何使用 indy 中的 IdHttpServer 检索参数和数据的帮助。
我的许多应用程序使用 TIdMultiPartFormDataStream 通过 php.ini 发送数据。由于某种原因,我想使用 TIdHTTPServer 来验证参数并将请求转发到其目的地。
我创建了一个简短的示例供您查看。
uses
IdContext, IdMultipartFormData;
// Server Side------------------------------------------------
IdHTTPServer1.Defaultport := 88;
IdHTTPServer1.active := True;
procedure TForm1.IdHTTPServer1CommandGet(AContext: TIdContext;
ARequestInfo: TIdHTTPRequestInfo; AResponseInfo: TIdHTTPResponseInfo);
begin
// the request will be pass through its destination by POST/GET
// and send the result back to the client apps.
AResponseInfo.ContentText := ARequestInfo.Params.Text;
end;
// Client Side------------------------------------------------
// This will work using the standard Post or Get
procedure TForm1.btnPost1Click(Sender: TObject);
var
sl: TStringList;
res: String;
begin
sl := TStringList.Create;
try
sl.Add('Param1=Data1');
sl.Add('Param2=Data1');
sl.Add('Param3=Data2');
sl.Add('Param4=Data3');
res := IdHTTP1.Post('http://localhost:88/some.php', sl);
ShowMessage(res);
finally
sl.Free;
end;
end;
//how can i get the parameters and value for this code in my IdHttpServer
procedure TForm1.btnPost2Click(Sender: TObject);
var
mfd: TIdMultiPartFormDataStream;
res: String;
begin
mfd := TIdMultiPartFormDataStream.Create;
try
mfd.AddFormField('Param1', 'Data1');
mfd.AddFormField('Param2', 'Data1');
mfd.AddFormField('Param3', 'Data2');
mfd.AddFormField('Param4', 'Data3');
res := IdHTTP1.Post('http://localhost:88/some.php', mfd);
ShowMessage(res);
finally
mfd.Free;
end;
end;
我怎么知道客户端应用程序是否传递了 TIdMultiPartFormDataStream 类型的参数?
