前不久看到版面上有一个下载mp3的程序,挺好用的.看了一下,有一个问题不太懂.

直接搜索之后得到的baidu的页面是用urllib2.urlopen()来下载下来的,然后从里 
面提取出来歌曲的链接之后,比如下面这样的链接:

http://202.108.23.172/m?ct=134217728&tn;=baidusg,\xc1\xb5\xd7\xc5\xb6\xe0\xcf\xb2\xbb\xb6%20%20\xc9\xf1\xb5\xf1\xcf\xc0\xc2\xc2&word;=mp3,http://www.odwan.com/UploadFiles/Y2JjamZmaHFqZWNmbWdwazE$.mp3,,[%C1%BA%BE%B2%C8%E3+%C1%B5%D7%C5%B6%E0%CF%B2%BB%B6]&lm;=16777216

复制到浏览器的地址栏,就可以打开网页,用wget也可以下载下来,为什么用python 
的urllib2.urlopen(url)就不行呢?

谢谢.

你这url可以使用urlopen的

不过我在做baidu的下载工具，知道有些url不行是因为url中有中文

你应该先用gbk解码,然后再转换成utf-8

>>> a = '天才狐狸'
>>> a
'\xcc\xec\xb2\xc5\xba\xfc\xc0\xea'
>>> a.encode('utf-8')
Traceback (most recent call last):
File "", line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0xcc in position 0:
ordinal not in range(128)
>>> a.decode('gbk').encode('utf-8')
'\xe5\xa4\xa9\xe6\x89\x8d\xe7\x8b\x90\xe7\x8b\xb8'
>>>

>>> s="我"
>>> s
'\xe6\x88\x91'
>>> s.decode("utf-8")
u'\u6211'

字符串编码分为处理编码和传输编码的。处理编码是一种内部编码，就是unicode，你需要先将字符串转换为内部处理编码，在转换成另外一种传输编码。也就是先转换成unicode，然后在编码。
楼上的说的很有道理：

>>>a="天才狐狸"
>>>a.decode("gbk").encode("utf-8")
或者
>>> unicode(a,"gbk").encode("utf-8")

url中的中文应该被转义,否则也不叫url了

因为取出的这个链接里面包含有空格和中文，理论上来讲用quote来编码是没有问题的，但是实际上我在做的时候编码后打不开，于是就进行了相应的处理，把无关紧要的空格和中文给剔除了。
