UnicodeDecodeError在SUDS中，但仅在py2exe生成的.exe中。

Question

我有一个Python2.7脚本SendPreord.py，它使用SUDS与web服务进行通信。在脚本中，我调用一个web服务方法，将一些参数作为字符串 (runJob(par1, par2, par3))传递。它能很好地处理字符串中的西欧字符。我在Eclipse中使用PyDev运行它。

然后，我使用.exe生成py2exe。现在它给了我错误

Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 484: ordinal not in range(128)

导致错误的代码是：

result = ws_client.service.runJob(par1, par2, par3)

经过调查，我意识到删除像°èòà这样的字符可以解决这个问题.可是，我不会呀!我必须保留我要传递的字符串。

因此，在传递字符串之前，我尝试了对它们进行解码：

result = ws_client.service.runJob(par1.decode('latin9'), par2.decode('latin9'), par3.decode('latin9'))

同样，全部在.py中工作，但在.exe中不起作用。也许PyDev在某种程度上纠正了这个问题？

Setup.py：

from distutils.core import setup
import py2exe
setup(console=['src/SendPreord.py'])

py2exe输出日志中有趣的摘录：

Python在编码转换方面的猜测已经让你被咬了。您尝试过的第一部分是正确的:首先使用(希望是正确的)编码解码。在发送之前，您必须再次对其进行编码，最好使用类似于UTF-8的代码，否则Python会尝试“默认”编码(在大多数安装中是ASCII)。I've written this here before
