示例代码
#include "imcvcodc.h" //base64 声明头文件
static TPtrC8 Base64EncodeC(const TDesC8 & aSourceBuf)
{
TImCodecB64 B64;
//Using base64 the size is increased by 1/3
HBufC8 * buffer = HBufC8::NewLC(aSourceBuf.Length() + aSourceBuf.Length()/3);

BASE64编码
//encode string to base64 encoding with clean stack
TPtrC8 ptr = StringUtil::Base64EncodeC(_L8("This is test"));
//Change to TDesC16
HBufC *buff16 = HBufC::NewLC(ptr.Length());
buff16->Des().Copy(ptr);
//Do something....
...
//clean buffer
CleanupStack::PopAndDestroy(2);
结果

BASE64编码
//Decode base64 encoding with clean stack

提示
除了需要包含”imcvcodc.h”头文件外，你还需要在.mmp文件中加入 imut.lib
