Symbian平台下Base64编码及解码

TImCodecB64类是symbian平台下提供的Base64编码解码类，你在官方文档的sdk可能找不到关于Base64编码解码类的描述。但是此类确实存在于sdk的开发包中，在这里给出TImCodecB64类的简单用法示范。

示例代码

#include  "imcvcodc.h" //base64 声明头文件 static HBufC8* Base64EncodeLC(const TDesC8 & aSourceBuf){     TImCodecB64 B64;    //Using base64 the size is increased by 1/3    HBufC8 * buffer = HBufC8::NewL(aSourceBuf.Length() + aSourceBuf.Length()/3);    B64.Initialise();    TPtr8 buffPtr = buffer->Des();    B64.Encode(aSourceBuf, buffPtr);    return  buffer;} static HBufC8* Base64DecodeLC(const TDesC8 & aSourceBuf){    TImCodecB64 B64;    HBufC8 * buffer = HBufC8::NewLC(aSourceBuf.Length());    B64.Initialise();    TPtr8 buffPtr = buffer->Des();    B64.Decode(aSourceBuf, buffPtr);    return  buffer;}

BASE64编码

//encode string to base64 encoding with clean stackHBufC8* encodeBuf = StringUtil::Base64EncodeLC(_L8("This is test"));//Change to TDesC16HBufC *buff16 = HBufC::NewLC(ptr.Length());buff16->Des().Copy(ptr);//Do something.......//clean bufferCleanupStack::PopAndDestroy(2);

结果

VGhpcyBpcyB0ZXN0

 

BASE64解码

//Decode base64 encoding with clean stackHBufC8* decodeBuf = StringUtil::Base64DecodeLC(_L8("VGhpcyBpcyB0ZXN0")); //Change to TDesC16HBufC *buff16 = HBufC::NewLC(ptr.Length());buff16->Des().Copy(ptr);//Do something ...//clean bufferCleanupStack::PopAndDestroy(2);

结果

This is test

 

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
