【已解决】Python中unquote乱码的问题

【背景】

Python中，已经通过代码，获得了对应的dict类型的变量了。

其中对应的评论内容部分是：

"cms_body" : "%E9%98%BF%E6%9D%B0%E5%A7%90%E5%A6%B9%E7%BB%A7%E7%BB%AD%E6%B3%AA%E6%B5%81%E6%BB%A1%E9%9D%A2%E2%80%A6%E2%80%A6%28%2A%5E__%5E%2A%29%26nbsp%3B%E8%BF%99%E7%A7%8D%E8%A1%A8%E8%BE%BE%E5%A5%BD%E5%96%9C%E5%89%A7%E5%93%A6%EF%BC%81%E4%BA%8C%E5%85%AC%E4%B8%BB%E5%A4%A7%E4%BA%BA%E6%88%90%E7%BB%A9%E4%B8%8D%E9%94%99%E5%93%A6%EF%BC%81%E4%B9%88%E4%B9%88%E5%93%92%3Cimg%20src%3D%22http%3A%2F%2Fwww.sinaimg.cn%2Fuc%2Fmyshow%2Fblog%2Fmisc%2Fgif%2FE___0088EN00SIGT.gif%22%20style%3D%22margin%3A1px%3Bcursor%3Apointer%3B%22%20onclick%3D%22window.open%28%27http%3A%2F%2Fblog.sina.com.cn%2Fmyshow2010%27%29%22%20border%3D%220%22%20title%3D%22%E9%A1%B6%22%20%2F%3E",

并且也是通过：

unquotedCmsBody = urllib.unquote(mainCmtDataDict['cms_body']);

去获得对应的内容，但是结果还是原始的，带%号的那种内容，不过其中的其他英文部分，是unquote了：

而余下的，中文部分的内容，还始终是乱码，无法显示。

【解决过程】

1.自己去通过IDLE中去试了试，结果是：

以为自己对Python中的编码已经很懂了，结果遇到此处的问题，也还是感觉有点一头雾水，还是解决不了。

2.搜了半天的资料了，尝试了半天，都还是没解决。

3.最后是参考：

python中unicode、utf8、gbk等编码问题–Code Monkey·程序猿，python/php/iOS程序员博客。

的：

“

特别注意：utf8编码、gbk编码的原型加上u然后再转unicode是错误写法，肯定转不了，那怎样去掉u呢？str()函数也不能直接转，只好把u’%E9%95%BF%E6%98%A5%E5%B8%82’用str()处理去掉u，然后一切都OK了。

>>> urllib.unquote(str(s)).decode(‘utf8’)

u'\u957f\u6625\u5e02'
>>> print urllib.unquote(str(s)).decode('utf8')

使用：

        cmdBodyStr = str(mainCmtDataDict['cms_body']);
        logging.info("cmdBodyStr=%s", cmdBodyStr);
        urldecodedCmsBody = urllib.unquote(cmdBodyStr);
        logging.info("urldecodedCmsBody=%s", urldecodedCmsBody);

才解决了问题：

LINE 754 INFO cmdBodyStr=%E9%98%BF%E6%9D%B0%E5%A7%90%E5%A6%B9%E7%BB%A7%E7%BB%AD%E6%B3%AA%E6%B5%81%E6%BB%A1%E9%9D%A2%E2%80%A6%E2%80%A6%28%2A%5E__%5E%2A%29%26nbsp%3B%E8%BF%99%E7%A7%8D%E8%A1%A8%E8%BE%BE%E5%A5%BD%E5%96%9C%E5%89%A7%E5%93%A6%EF%BC%81%E4%BA%8C%E5%85%AC%E4%B8%BB%E5%A4%A7%E4%BA%BA%E6%88%90%E7%BB%A9%E4%B8%8D%E9%94%99%E5%93%A6%EF%BC%81%E4%B9%88%E4%B9%88%E5%93%92%3Cimg%20src%3D%22http%3A%2F%2Fwww.sinaimg.cn%2Fuc%2Fmyshow%2Fblog%2Fmisc%2Fgif%2FE___0088EN00SIGT.gif%22%20style%3D%22margin%3A1px%3Bcursor%3Apointer%3B%22%20onclick%3D%22window.open%28%27http%3A%2F%2Fblog.sina.com.cn%2Fmyshow2010%27%29%22%20border%3D%220%22%20title%3D%22%E9%A1%B6%22%20%2F%3E

LINE 756 INFO urldecodedCmsBody=阿杰姐妹继续泪流满面……(*^__^*) 这种表达好喜剧哦！二公主大人成绩不错哦！么么哒<img src="http://www.sinaimg.cn/uc/myshow/blog/misc/gif/E___0088EN00SIGT.gif" style="margin:1px;cursor:pointer;" onclick="window.open(‘http://blog.sina.com.cn/myshow2010’)" border="0" title="顶" />

LINE 758 INFO curType=<type ‘str’>

整理了之后，使用代码：

        cmsBodyUni = mainCmtDataDict['cms_body'];
        logging.info("cmsBodyUni=%s", cmsBodyUni);
        curType = type(cmsBodyUni);
        logging.info("curType=%s", curType);
        cmdBodyStr = str(cmsBodyUni);
        logging.info("cmdBodyStr=%s", cmdBodyStr);
        curType = type(cmdBodyStr);
        logging.info("curType=%s", curType);
        urlunquotedCmsBodyStr = urllib.unquote(cmdBodyStr);
        logging.info("urlunquotedCmsBodyStr=%s", urlunquotedCmsBodyStr);
        curType = type(urlunquotedCmsBodyStr);
        logging.info("curType=%s", curType);
        urlunquotedCmsBodyUni = urlunquotedCmsBodyStr.decode("UTF-8");
        curType = type(urlunquotedCmsBodyUni);
        logging.info("curType=%s", curType);
        logging.info("urlunquotedCmsBodyUni=%s", urlunquotedCmsBodyUni);

输出结果：

【总结】

此处是，已经获得了，Unicode类型的字符串，字符串内容是，quote过的，带百分号%的，比如：

%E8%BD%AC%E5%8F%91%E5%BE%AE%E5%8D%9A

而此处，想要获得对应的中文内容，则需要：

1.先去把当前的unicode字符串转换为普通的str

quotedStringStrType= str(quotedStringUnicodeType)

2.再去通过urllib.unquote去解码，得到真正的中文内容

urlunquotedOriginalStr = urllib.unquote(quotedStringStrType);

注意：

此处的最终解码得到的字符串是UTF-8编码的。
