Python Facebook API-游标分页 [英] Python Facebook API - cursor pagination

问题描述

我的问题涉及学习如何使用Facebook的Python API检索我的整个朋友列表. 当前结果返回一个对象，该对象的朋友数量有限，并具有指向下一个"页面的链接.我该如何使用它来获取下一组朋友?(请把链接发布到可能的重复项)任何帮助将不胜感激.通常，我需要了解涉及API使用的分页.

My question involves learning how to retrieve my entire list of friends using Facebook's Python API. The current result returns an object with limited number of friends and a link to the 'next' page. How do I use this to fetch the next set of friends ? (Please post the link to possible duplicates) Any help would be much appreciated. In general, I need to learn about the pagination involved the API usage.

import facebook
import json

ACCESS_TOKEN = "my_token"

g = facebook.GraphAPI(ACCESS_TOKEN)

print json.dumps(g.get_connections("me","friends"),indent=1)

推荐答案

遗憾的是，分页文档是一个未解决的问题将近两年了.您应该可以使用<(例如此示例)进行分页a href ="http://docs.python-requests.org/en/latest/user/install/" rel ="nofollow noreferrer">请求:

Sadly the documentation of pagination is an open issue since almost 2 years. You should be able to paginate like this (based on this example) using requests:

import facebook
import requests

ACCESS_TOKEN = "my_token"
graph = facebook.GraphAPI(ACCESS_TOKEN)
friends = graph.get_connections("me","friends")

allfriends = []

# Wrap this block in a while loop so we can keep paginating requests until
# finished.
while(True):
    try:
        for friend in friends['data']:
            allfriends.append(friend['name'].encode('utf-8'))
        # Attempt to make a request to the next page of data, if it exists.
        friends=requests.get(friends['paging']['next']).json()
    except KeyError:
        # When there are no more pages (['paging']['next']), break from the
        # loop and end the script.
        break
print allfriends

更新:有一个新的生成器方法可实现上述行为，并可用于遍历所有朋友，如下所示:

Update: There's a new generator method available which implements above behavior and can be used to iterate over all friends like this:

for friend in graph.get_all_connections("me", "friends"):
    # Do something with this friend.
