本文介绍了Python UnicodeDecodeError：'ascii'编解码器无法解码字节0xe2序号不在范围内（128）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图用Python在Google App Engine中编写我的第一个应用程序（应用程序链接： - 这只是一个实验性应用程序）。整个代码是波纹管。
但是，当我提交数据时，我收到这个错误（显示在日志中）：
（...）第265行，获取contractType：geted_contractType
UnicodeDecodeError：'ascii'编解码器无法解码位置949中的字节0xe2：序号不在范围内（128 ）
第265行在这个块中：
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，
c ontractType：geted_contractType
}）
我尝试进行更改，读取类似awnswers 或），但没有任何帮助。我无法弄清楚这段代码出了什么问题。有人可以找出是什么导致这样的错误，以及如何解决它？
我使用Python 2.7。
在此先感谢您的帮助！

解决方案
适当的模板系统。 Jinja2包含在AppEngine中。
然而，同时你的问题是你的模板是ASCII但你的数据不是（不能分辨是utf-8还是unicode ）。简单的解决方案是在每个模板字符串前加上 u 使其成为Unicode。
但是，您应该真的使用适当的模板系统。
I'm trying to write my first app in Google App Engine with Python (link of the app: http://contractpy.appspot.com/ - it's just an experimental app). The entire code is bellow.
But, when I submit the data, I'm getting this error (showed on logs):
(...) line 265, in get "contractType":geted_contractType
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 949: ordinal not in range(128)
Line 265 is in this if block:
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
})
I tried to make changes, read similar awnswers (like this or this), but nothing helped. I can't figure out in this code what is going wrong. Can someone figure out what is causing such error and how to fix it?
I'm using Python 2.7.
Thanks in advance for any help!

解决方案
You should really use a proper templating system. Jinja2 is included with AppEngine.
However in the meantime your problem is that your templates are ASCII but your data is not (can't tell if it's utf-8 or unicode). Easy solution is to prefix each template string with u to make it Unicode.
But, you should really use a proper templating system.
