我在提交之前尝试对此字符串进行urlencode.

queryString = 'eventName=' + evt.fields["eventName"] + '&' + 'eventDescription=' + evt.fields["eventDescription"]; 

我正在python上学习udacity课程,我们应该检查文档中的亵渎词.我正在使用网站http://www.wdylike.appspot.com/?q=(text_to_be_checked_for_profanity).要检查的文本可以作为上述URL中的查询字符串传递,并且在检查亵渎词后网站将返回true或false.以下是我的代码.

import urllib.request

# Read the content from a document
def read_content():

    quotes = open("movie_quotes.txt")
    content = quotes.read()
    quotes.close()
    check_profanity(content)



def check_profanity(text_to_read):
    connection = urllib.request.urlopen("http://www.wdylike.appspot.com/?q="+text_to_read)
    result = connection.read()
    print(result)
    connection.close

read_content()

它给了我以下错误

我试图读取内容的文档包含一个字符串" Hello world "但是,如果我将字符串更改为" Hello + world ",则相同的代码将起作用并返回所需的结果.有人可以解释为什么会发生这种情况以及解决方法是什么？
