Delphi错误E2010不兼容的类型: 'string' and 'procedure, untyped pointer or untyped parameter'

Question

我使用了 TStringList 和类似的东西:

geo: TStringList;
response: TStringStream;
  begin
  http:=tidhttp.Create(nil);
  try
    { TODO -oUser -cConsole Main : Insert code here }
    geo:=TStringList.Create;
    response:=TStringStream.Create('');
    geo.Add('name=stas');
    geo.Add('pass=431');
    s:=http.Get('http://test.me');
    writeln(http.ResponseText);
    writeln(s);
    s:=http.Post('http://test.me',geo,response);

但有什么不对劲。例如，当我运行它时，它会发出错误 [[DCC Error] consoleHttp.dpr(29): E2010 不兼容类型:'字符串'和'过程、非类型化指针或非类型化参数'] 的警报 s:=http.Post('http://test.me',geo,response)。我做错了什么？

此错误意味着您向方法 TIdHTTP.post 传递了错误的参数。该方法有多个重载

function Post(AURL: string; ASource: TIdStrings): string; overload;
function Post(AURL: string; ASource: TIdStream): string; overload;
function Post(AURL: string; ASource: TIdMultiPartFormDataStream): string; overload;
procedure Post(AURL: string; ASource: TIdMultiPartFormDataStream; AResponseContent: TIdStream); overload;
procedure Post(AURL: string; ASource: TIdStrings; AResponseContent: TIdStream); overload;
procedure Post(AURL: string; ASource, AResponseContent: TIdStream); overload;

但没有一个与您传递的参数匹配。
