今天用python3.x在解析網頁時發生了個錯誤："UnicodeEncodeError: 'ascii' codec can't encode characters"，下面是錯誤信息：
C:\Python\Python35-32\python.exe C:/Users/XXXXXXX/XXXX.py
Traceback (most recent call last):
File "C:/Users/XXXXXXX/XXXX.py", line 22, in <module>
text = gethtml(searchUrl)

htmlData = urllib.request.urlopen(url)
File "C:\Python\Python35-32\lib\urllib\request.py", line 162, in urlopen
return opener.open(url, data, timeout)

self._output(request.encode('ascii'))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 17-20: ordinal not in range(128)
Process finished with exit code 1所以很明顯是因爲在發送的請求中有字符集的問題。
下面是code片段：
def gethtml(url):
htmlData = urllib.request.urlopen(url)
htmlText = htmlData.read()
return htmlText
print gethtml("http://xxxx/測試")換爲：
def gethtml(url):
htmlData = urllib.request.urlopen(url)
htmlText = htmlData.read()
return htmlText
print gethtml("http://xxxx/%s"%urllib.parse.quote("測試"))
