Python - 在 HTTP POST 请求中发送 unicode 字符(以\u 为前缀)

Question

我正在编写一个程序来获取和编辑维基百科上的文章，但在处理以\u 为前缀的 Unicode 字符时遇到了一些麻烦。我已经尝试过 .encode("utf8") ，但它似乎在这里不起作用。如何正确编码这些以\u 为前缀的值以发布到维基百科？请参阅this edit对于我的问题。这是一些代码:获取页面:

url = "http://en.wikipedia.org/w/api.php?action=query&format=json&titles="+urllib.quote(name)+"&prop=revisions&rvprop=content"
articleContent = ClientCookie.urlopen(url).read().split('"*":"')[1].split('"}')[0].replace("\\n", "\n").decode("utf-8")

在发布页面之前:

data = dict([(key, value.encode('utf8')) for key, value in data.iteritems()])
data["text"] = data["text"].replace("\\", "")
editInfo = urllib2.Request("http://en.wikipedia.org/w/api.php", urllib.urlencode(data))

Answer 1

您正在下载 JSON 数据，但未对其进行解码。使用json library为此:

import json

articleContent = ClientCookie.urlopen(url)
data = json.load(articleContent)

JSON 编码数据看起来很像 Python，它也使用 \u 转义，但它实际上是 JavaScript 的子集。

data 变量现在拥有一个深层数据结构。从字符串分割来看，您想要这一段:

articleContent = data['query']['pages'].values()[0]['revisions'][0]['*']

现在articleContent是一个实际的unicode()实例；这是您要查找的页面的修订文本:

>>> print u'\n'.join(data['query']['pages'].values()[0]['revisions'][0]['*'].splitlines()[:20])
