python 万能编码处理，gbk，unicode，utf-8互转

def getCoding(strInput): ''' 获取编码格式 ''' if isinstance(strInput, unicode): return "unicode" try: strInput.decode("utf8") return 'utf8' except: pass try: strInput.decode("gbk") return 'gbk' except: pass

def tran2UTF8(strInput): ''' 转化为utf8格式 ''' strCodingFmt = getCoding(strInput) if strCodingFmt == "utf8": return strInput elif strCodingFmt == "unicode": return strInput.encode("utf8") elif strCodingFmt == "gbk": return strInput.decode("gbk").encode("utf8")

def tran2GBK(strInput): ''' 转化为gbk格式 ''' strCodingFmt = getCoding(strInput) if strCodingFmt == "gbk": return strInput elif strCodingFmt == "unicode": return strInput.encode("gbk") elif strCodingFmt == "utf8": return strInput.decode("utf8").encode("gbk")
