gae python ascii编解码器无法解码字节2

当我试图在Google App Engine中的数据库中存储信息时，我遇到了这个错误

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 57: ordinal not in range(128)

您正试图使用ASCII编解码器解码非ASCII字符。您需要知道输入字符是如何编码的

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 57: ordinal not in range(128)

与流行的观点相反，二进制数据没有内在的意义。它只有作者指定的含义。

听起来像是有unicode编码错误，但您没有足够的信息来帮助找出问题所在

有两件事需要尝试

1.

#-*-编码：utf-8-*-

，位于进行调用的文件顶部（如果文件中有unicode，例如☃ 或€

2.）确保将unicode发送到db而不是str。否则会发生这种情况

>>> x = eval("'Capit\\xc3\\xa1n\\n'")
>>> x 
'Capit\xc3\xa1n\n'
>>> x[5]
'\xc3'
>>> len(x[5])
1

如您所见，它将多位unicode转换为\xc3\xa1n，转换为2个字符，第一个字符超出了ascii生成的范围，因为它是utf-8编码位之一（这就是为什么普通ascii主要在utf-8中工作）
