注意编码问题解決方法: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 0: ordinal not in range(128)所以解決方法有3種一種是全都轉byte string 一種是全都轉unicode string 第三種是更改設定預設解碼器為utf-8app engine上我不知道怎麼更改設定預設解碼器 所以只說前2種1.全都轉byte stringself.response.out.write("你好"+self.request.get("argu").encode('utf-8'))2.全都轉unicode stringself.response.out.write(u"你好"+self.request.get("argu"))P.S.資料庫存入和讀取以及self.request拿到的參數預設就都是unicode string,若是要把byte string轉unicode string可以這樣轉unicode(unicodestring,"utf-8")
