前言:
现在很多STMP服务器在发送邮件时均需重新认证 ![]() ![]() ![]() ![]() ![]() ![]() 由于前段时间在做 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() 实现: 1、在NMSMTP ![]() var strUserName, strPassword: String; begin strUserName := EncodeString('CoolSlob');//CoolSlob是服务器 ![]() strPassword := EncodeString('Password');//Password是密码 {进行认证 ![]() ![]() nmsmtp1.Transaction('EHLO') ; nmsmtp1.Transaction('AUTH LOGIN'); nmsmtp1.Transaction(strUserName); nmsmtp1.Transaction(strPassword); StatusBar1.SimpleText := '连接成功'; end; 2、EncodeString ![]() {对参数Decoded ![]() ![]() ![]() ![]() function EncodeString(Decoded: ![]() var mmTemp,mmDecoded:TMemoryStream; strTemp:TStrings; begin mmTemp := TMemoryStream.Create; mmDecoded:=TMemoryStream.Create; strTemp:=TStringList.Create; strTemp.Add(Decoded); strTemp.SaveToStream(mmTemp); mmTemp.Position := 0; {剔除mmTemp从strTemp中带来 ![]() ![]() mmDecoded.CopyFrom(mmTemp,mmTemp.Size-2); {对mmDecoded进行Base64编码 ![]() ![]() EncodeBASE64(mmTemp,mmDecoded); {获得Base64编码后 ![]() ![]() mmTemp.Position:=0; strTemp.LoadFromStream(mmTemp); {返回结果必须从strTemp[0]中获得 ![]() 带来不必要 ![]() ![]() Result:=strTemp[0]; end; 3、EncodeBASE64 ![]() function EncodeBASE64(Encoded: TMemoryStream ; Decoded: TMemoryStream): Integer; const _Code64: String[64] = ('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'); var I: LongInt; B: J, K, L, M, Quads: Integer; Stream: ![]() EncLine: String; begin Encoded.Clear; Stream := ''; Quads := 0; {为提高效率 ![]() ![]() J := Decoded.Size div 2280; Decoded.Position := 0; {对前J*2280个字节流进行编码} for I := 1 to J do begin Decoded.Read(B, 2280); for M := 0 to 39 do begin for K := 0 to 18 do begin L:= 57*M + 3*K; Stream[Quads+1] := _Code64[(B[L] div 4)+1]; Stream[Quads+2] := _Code64[(B[L] mod 4)*16 + (B[L+1] div 16)+1]; Stream[Quads+3] := _Code64[(B[L+1] mod 16)*4 + (B[L+2] div 64)+1]; Stream[Quads+4] := _Code64[B[L+2] mod 64+1]; Inc(Quads, 4); ![]() begin Stream[0] := #76; EncLine := Stream+#13#10; Encoded.Write(EncLine[1], Length(EncLine)); Quads := 0; end; end; end; end; {对以2280为模 ![]() J := (Decoded.Size mod 2280) div 3; for I := 1 to J do begin Decoded.Read(B, 3); Stream[Quads+1] := _Code64[(B[0] div 4)+1]; Stream[Quads+2] := _Code64[(B[0] mod 4)*16 + (B[1] div 16)+1]; Stream[Quads+3] := _Code64[(B[1] mod 16)*4 + (B[2] div 64)+1]; Stream[Quads+4] := _Code64[B[2] mod 64+1]; Inc(Quads, 4); {每行76个 ![]() ![]() begin Stream[0] := #76; EncLine := Stream+#13#10; Encoded.Write(EncLine[1], Length(EncLine)); Quads := 0; end; end; {“=”补位} ![]() begin Decoded.Read(B, 2); Stream[Quads+1] := _Code64[(B[0] div 4)+1]; Stream[Quads+2] := _Code64[(B[0] mod 4)*16 + (B[1] div 16)+1]; Stream[Quads+3] := _Code64[(B[1] mod 16)*4 + 1]; Stream[Quads+4] := '='; Inc(Quads, 4); end; ![]() begin Decoded.Read(B, 1); Stream[Quads+1] := _Code64[(B[0] div 4)+1]; Stream[Quads+2] := _Code64[(B[0] mod 4)*16 + 1]; Stream[Quads+3] := '='; Stream[Quads+4] := '='; Inc(Quads, 4); end; Stream[0] := Chr(Quads); ![]() begin EncLine := Stream+#13#10; Encoded.Write(EncLine[1], Length(EncLine)); end; Result := Encoded.Size; end; 0
