python2.7 - python 中文寫入文件后亂碼

問題描述

一個很簡單的小爬蟲程序

for i in L:content = urllib2.urlopen(’http://X.X.X.X/cgi-bin/GetDomainOwnerInfo?domain=%s’ %i)html = content.read()with open(’domain_test.xml’,’a’) as f: f.write(html) print html

print 的結果是中文：

<domaininfo strDomain='XXX.com.' strOwner='XXX' strDepartment='云平臺部' strBusiness='[互聯網業務系統 - XXX' strUser='XXX;'>

但直接打開xml文本的時候卻是亂碼：

<domaininfo strDomain='XXX.com.' strOwner='XXX' strDepartment='?o‘?13??°é?¨' strBusiness='[?o’è?”??‘???????3???? - ?????‰?–1?o”?”¨]' StrUser='XXX;'>

Windows 7 操作系統，python 2.7

請問一下各位，這個問題如何解決？

問題解答

你需要知道 content 的編碼方式，并考慮是否要轉換

你需要用 utf-8 打開文件，然后寫入

codecs.open(filename, mode[, encoding[, errors[, buffering]]])

Open an encoded file using the given mode and return a wrapped versionproviding transparent encoding/decoding. The default file mode is ’r’meaning to open the file in read mode.

Note The wrapped version will only accept the object format defined bythe codecs, i.e. Unicode objects for most built-in codecs. Output isalso codec-dependent and will usually be Unicode as well. Note Filesare always opened in binary mode, even if no binary mode was specified. This is done to avoid data loss due to encodings using8-bit values. This means that no automatic conversion of ’n’ is doneon reading and writing. encoding specifies the encoding which is to beused for the file.errors may be given to define the error handling. It defaults to’strict’ which causes a ValueError to be raised in case an encodingerror occurs.buffering has the same meaning as for the built-in open() function. Itdefaults to line buffered.

import codecsf = codecs.open('domain_test.xml', 'w', 'utf-8')回答2：

試試在文件開頭加上 # -*- coding: utf-8 -*-

在文件開頭加上 #coding:utf-8
