我想在delphi 7上用indy 9.00.10发送表情符号。我使用tnt VCL控件。 我发现这个url http://apps.timwhitlock.info/emoji/tables/unicode用于unicode和bytes代码。 如何使用indy将此代码转换为delphi常量发送。
我使用这个delphi代码发送消息给电报机器人:
procedure TBotThread.SendMessage(ChatID:String; Text : WideString;
parse_mode:string;disable_notification:boolean);
Var
Stream: TStringStream;
Params: TIdMultipartFormDataStream;
//Text : WideString;
msg : WideString;
Src : string;
LHandler: TIdSSLIOHandlerSocket;
begin
try
try
if FShowBotLink then
Text := Text + LineBreak + FBotUser;
msg := '/sendmessage';
Stream := TStringStream.Create('');
Params := TIdMultipartFormDataStream.Create;
Params.AddFormField('chat_id',ChatID);
if parse_mode <> '' then
Params.AddFormField('parse_mode',parse_mode);
if disable_notification then
Params.AddFormField('disable_notification','true')
else
Params.AddFormField('disable_notification','false');
Params.AddFormField('disable_web_page_preview','true');
Params.AddFormField('text',UTF8Encode(Text));
LHandler := TIdSSLIOHandlerSocket.Create(nil);
FidHttpSend.ReadTimeout := 30000;
FidHttpSend.IOHandler:=LHandler;
LHandler.SSLOptions.Method := sslvTLSv1;
LHandler.SSLOptions.Mode := sslmUnassigned;
FidHttpSend.HandleRedirects := true;
FidHttpSend.Post(BaseUrl + API + msg, Params, Stream);
finally
Params.Free;
Stream.Free;
ENd;
except
on E: EIdHTTPProtocolException do
begin
if E.ReplyErrorCode = 403 then
begin
WriteToLog('Bot was blocked by the user');
end;
end;
end;
end;
emojies的字节样本:
AERIAL_TRAMWAY = '\xf0\x9f\x9a\xa1';
AIRPLANE = '\xe2\x9c\x88';
ALARM_CLOCK = '\xe2\x8f\xb0';
ALIEN_MONSTER = '\xf0\x9f\x91\xbe';
抱歉英语不好!!!
答案 0 :(得分:0)
Telegram Bot API支持多种形式的输入:
我们支持
GET
和POST
HTTP方法。我们支持在Bot API请求中传递参数的四种方式:
- 网址查询字符串
- 应用程序/ x-WWW窗体-urlencoded
- application / json(上传文件除外)
- multipart / form-data(用于上传文件)
您正在使用最后一个选项。
Indy 9不支持Delphi 2009+或Unicode。 string
的所有用法都假定为AnsiString
,这是Delphi 7中的情况。任何AnsiString
添加到TIdMultipartFormDataStream
或TStrings
,甚至是UTF -8编码的一个将由TIdHTTP
以原样传输。但是,没有选项可以向服务器指定字符串数据实际上使用UTF-8作为字符集。但是,根据文档:
所有查询都必须使用UTF-8。
因此,不指定显式字符集可能不是问题。
如果您仍然遇到multipart/form-data
问题,请考虑使用application/x-www-form-urlencoded
(使用TIdHTTP.Post(TStrings)
)或application/json
(使用TIdHTTP.Post(TStream)
)代替:

话虽如此,您的函数的Text
参数是WideString
,它使用UTF-16,因此您应该能够发送任何Unicode文本,包括emojis。如果您尝试在代码中生成文本,请确保UTF-16正确编码任何非ASCII字符。例如,代码点U+1F601 GRINNING FACE WITH SMILING EYES
是UTF-16中的宽字符$D83D $DE01
:
var
Text: WideString;
Text := 'hi ' + #$D83D#$DE01; // 'hi '
SendMessage('@channel', Text, 'Markup', False);
或者,您可以在短信中使用HTML,这样就可以使用数字HTML实体对非ASCII字符进行编码。根据文件:
支持所有数字HTML实体。
代码点U+1F601
是HTML中的数字实体$#128513;
:
var
Text: WideString;
Text := 'hi $#128513;'; // 'hi '
SendMessage('@channel', Text, 'HTML', False);
