如何使用 Stack Exchange API 获取答案的正文？

Question

我正在使用StackAPI来获取投票最多的问题以及这些问题的投票最多的答案：-

from stackapi import StackAPI
SITE = StackAPI('stackoverflow')
SITE.max_pages=1
SITE.page_size=10

questions = SITE.fetch('questions', min=20, tagged='python', sort='votes')
for quest in questions['items']:
    if 'title' not in quest or quest['is_answered'] == False:
        continue
    title = quest['title']
    print('Question :- {0}'.format(title))
    question_id = quest['question_id']
    print('Question ID :- {0}'.format(question_id))
    top_answer = SITE.fetch('questions/' + str(question_id) + '/answers', order = 'desc', sort='votes')
    print('Most Voted Answer ID :- {0}'.format(top_answer['items'][0]['answer_id']))

现在使用这个answer_id我想得到答案的正文。我可以使用此 API 链接获取其余详细信息。

请参阅Stack Apps上的这些帖子：

1. 获取带有正文和答案的问题
2. 如何使用过滤器获取 API 响应中的问题/答案正文？
3. 我的过滤器没有返回任何结果。如何创建最小过滤器？

您需要使用自定义过滤器来获取问题/答案/帖子正文。

好消息是，您还可以使用自定义过滤器在获取问题的同时获取答案数据，从而无需稍后调用 API。

例如，如果您/questions使用过滤器调用路由：
    !*SU8CGYZitCB.D*(BDVIficKj7nFMLLDij64nVID)N9aK3GmR9kT4IzT*5iO_1y3iZ)6W.G*

您会得到如下结果：

"items": [ {
    "tags": ["python", "iterator", "generator", "yield", "coroutine"],
    "answers": [ {
        "owner": {"user_id": 8458, "display_name": "Douglas Mayle"},
        "is_accepted": false,
        "score": 248,
        "creation_date": 1224800643,
        "answer_id": 231778,
        "body": "<p><code>yield</code> is just like <code>return</code> - it returns what..."
        }, {
        "owner": {"user_id": 22656, "display_name": "Jon Skeet"},
        "is_accepted": false,
        "score": 139,
        "creation_date": 1224800766,
        "answer_id": 231788,
        "body": "<p>It's returning a generator. I'm not particularly familiar with Python, ..."
        }, {
        ...
    } ],
    "owner": {"user_id": 18300, "display_name": "Alex. S."},
    "is_answered": true,
    "accepted_answer_id": 231855,
    "answer_count": 40,
    "score": 8742,
    "creation_date": 1224800471,
    "question_id": 231767,
    "title": "What does the &quot;yield&quot; keyword do?"
    },
    ...

所以，改变这个：

questions = SITE.fetch('questions', min=20, tagged='python', sort='votes')

对于这样的事情：

questions = SITE.fetch('questions', min=20, tagged='python', sort='votes', filter='!*SU8CGYZitCB.D*(BDVIficKj7nFMLLDij64nVID)N9aK3GmR9kT4IzT*5iO_1y3iZ)6W.G*')

然后相应地调整你的for循环。
