我在python 3.4中有这段代码
import urllib.request
def read_text():
document = open(r"C:\mystuff\udacity\pruebatxt.txt")
lec = document.read()
document.close()
print(lec)
check_profanity(lec)
def check_profanity (text_to_check):
print(text_to_check)
lecture = urllib.request.urlopen("http://www.wdyl.com/profanity?q="+ urllib.parse.quote(text_to_check))
output=lecture .read()
print(output)
lecture.close()
read_text()
它给了我这个错误:
File "C:\Python34\lib\urllib\request.py", line 1159, in do_request_
raise URLError('no host given')
urllib.error.URLError: <urlopen error no host given>
可能出现什么问题?

urlopen()
会返回响应,而非请求。您无法再将其传递给urlopen()
。
删除多余的urlopen()
电话:
lecture = urllib.request.urlopen("http://www.wdyl.com/profanity?q="+text_to_check)
output = lecture.read()
您的代理配置可能已损坏;通过检查Python在Windows注册表中找到的内容,验证您的代理是否合理:
print(urllib.request.getproxies())
或完全绕过代理支持:
lecture = urllib.request.urlopen(
"http://www.wdyl.com/profanity?q="+text_to_check
proxies={})

您的代码返回二进制字符串。将它解码为ascii格式会更好:
with urllib.request.urlopen("http://www.wdyl.com/profanity?q=" + urllib.parse.quote(text_to_check)) as response:
output = response.read()
output = output.decode('ascii')
print (output)
