我正在尝试使用Python在Google App Engine上编写我的第一个应用程序(应用程序链接:http://contractpy.appspot.com/ - 这只是一个实验性的应用程序)。整个代码如下。
但是,当我提交数据时,我会收到以下错误(显示在日志中):
(...) line 265, in get "contractType":geted_contractType
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 949: ordinal not in range(128)
在这个if代码块中,第265行被执行:
self.response.out.write(yourcontract % {"resident":geted_resident_name,
"nacionality":geted_user_nacionality,
"SSN":geted_user_SSN,
"SSN_error":geted_SSN_error,
"driverLicense":geted_user_driverLicense,
"email":geted_user_email,
"witness ":geted_witness ,
"owner":geted_owner,
"contractType":geted_contractType
})
我试图进行更改,阅读类似的答案(例如这个或这个),但是没有帮助。我无法确定在这段代码中出了什么问题。有人可以找出是什么原因导致了这样的错误,并且如何修复吗?
我正在使用Python 2.7。
非常感谢您提供的任何帮助!
