在Python / AppEngine中传递GET数据时的UnicodeDecodeError [英] UnicodeDecodeError when passing GET data in Python/AppEngine

问题描述

这感觉像是一个非常基本的问题，但我一直无法找到答案。

This feels like a really basic question, but I haven't been able to find an answer.

我想从一个url读取数据，例如从查询字符串获取数据。我在Python中使用 webapp 框架。我尝试了下面的代码，但由于我在Python / appengine上有一个初学者，所以我肯定做了一些错误的事情。

I would like to read data from an url, for example GET data from a querystring. I am using the webapp framework in Python. I tried the following code, but since I've a total beginner at Python/appengine, I've certainly done something wrong.

class MainPage(webapp.RequestHandler):
    def get(self):
        self.response.out.write(self.request.get('data'))

application = webapp.WSGIApplication([('/', MainPage),('/search', Search),('/next', Next)],debug=False)

def main():
    run_wsgi_app(application)

if __name__ == "__main__":
    main()

在我的测试环境中进行测试时，URL http：// localhost /？data = test 只会在下面返回此错误消息。

When testing in my test environment, the URL http://localhost/?data=test just returns this error message below. Without the querystring, it just displays a blank page as expected.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd6 in position 40: ordinal not in range(128)

我做错了什么，我应该怎么做？

What am I doing wrong and what should I do instead?

推荐答案

您试着例如打印实际包含不同字符集数据的ASCII编码字符串。这可能发生，例如用Latin-1编码的数据。尝试使用

You try to e.g. print an ASCII coded string actually containing data of a different charset. This can happen e.g. with Latin-1 encoded data. Try converting your input to unicode using

unicoded = unicode(non_unicode_string, source_encoding)

其中 source_encoding 类似于'cp1252'，'iso-8859-1'等等，然后发送给输出。

where source_encoding is something like 'cp1252', 'iso-8859-1' etc., and sending this to output.
