Question

我正在尝试从特定国家/地区获取推文。我正在使用tweepy api来获取推文。这是我到目前为止的代码 -

api = tweepy.API(auth)
places = api.geo_search(query="India", granularity="country")
place_id = places[0].id
public_tweets = api.search(q="place:%s" % place_id)
for one in public_tweets:
        print(one.place)

以下是我获取上述代码段的结果 -

大部分推文都没有地理标记。如何确保结果中只显示地理标记的推文？

Answer 1

我也遇到过这个问题，其中推文的实际地理代码总是丢失。但是，您不应该需要每条推文的实际地理代码来满足您的要求;相反，您可以搜索特定地理区域内的推文，指定坐标和半径，如下所示：

def wordsearch(word, max_tweets, lang, geocode, since, out):
    # Query for 100 tweets that have word in them and store it in a list 
    searched_tweets = [status for status in tweepy.Cursor(api.search, n=max_tweets, q=word, lang=lang,  geocode=geocode, since=since).items(max_tweets)]
    print("Number of Matches: %d\n" % len(searched_tweets))
    csvfile = open(out, 'a')
    csvWriter = csv.writer(csvfile)
    for t in searched_tweets:
        csvWriter.writerow([t.created_at, t.text.encode('utf-8'), t.author.screen_name, t.place, t.retweeted, t.retweet_count, (not t.retweeted and 'RT @' not in t.text)])
    csvfile.close()

wordsearch('dead', 100, "en", "37.9,91.8,1000mi", "2017-01-01",      "result.csv")

Answer 2

你以错误的方式接近这个。这两个功能不会那样工作。

首先查看Twitter文档：

GET geo/search，您正在正确查找信息，但正如文档中所述，它不适用于GET搜索/推文

这是使用可以附加的查找位置的推荐方法状态/更新。

GET search/tweets，它仅用于查找具有您正在寻找的特定单词（或单个单词）列表的推文。不能将geo_ids作为查询的一部分包含在内，除非您正在寻找包含它的推文

返回与指定查询匹配的相关推文的集合

geo_ids用于here。如果向下滚动并查看提供的示例将给出一个想法，或者在（1）中的文档中提到的状态/更新。

如果您需要地理编码的推文，则可以使用geocode中的GET search/tweets功能来限制位置以获取推文。这将为您提供该位置的所有推文，一旦您获得这些推文，您就可以过滤地理编码的推文。

过滤器必须在您的最终完成，而不是Twitter。
