【问题描述】：

一直在玩 Twitter API。事情进展顺利，直到我为搜索添加了开始和结束时间以及粒度。 根据 Twitter api docs，我相当有信心字符串值是正确的，并且 正确添加到参数。 但是我在参数上做错了什么，有人可以帮我吗？

有效的代码，IE 导致 200 响应和推文：

keywords = 'telsa'
api, query = 'https://api.twitter.com/2', '/tweets/search/recent'
request = f'apiquery'
params = 'query': keywords,
          'tweet.fields': 'created_at,lang', # no space before lang
          'max_results': '10'
header = 'authorization':f'Bearer bearer_token'

response = requests.get(request, headers=header, params=params)
if response: # boolean True if response is 200,
    print(response.response.json())
else:
    print(response)
    print(params)

不起作用的代码：400 响应：添加 start_time、end_time、粒度

<snip>
header = 'authorization':f'Bearer bearer_token'

**************** NEW CODE **************************
# Get datetime for now and 7 days ago, correctly formatted for Twitter API
dtformat = '%Y-%m-%dT%H:%M:%SZ'
from datetime import datetime, timedelta
time = datetime.now()
start_time = time - timedelta(days=7)

# convert to strings
start_time, end_time = start_time.strftime(dtformat), time.strftime(dtformat)

# Add new parameters to params dict
params['start_time'] = start_time
params['end_time']  = end_time
params['granularity'] = 'HOUR'
****************************************************

response = requests.get(request, headers=header, params=params)
<snip>

..以及最后打印的参数：

params: 'query': 'telsa', 'tweet.fields': 'created_at,lang', 'max_results': '10', 'start_time': '2021-03-14T14:14:44Z', 'end_time': '2021-03-21T14:14:44Z', 'granularity': 'HOUR'

twitter API docs 显示 start_time、end_time 示例值。它们的格式相同。 最近发布的使用 API v2 的教程以相同的方式附加了新参数。 添加 3 个新时间变量的任意组合会导致 400 响应。 Windows 10、64 如果重要的话

【参考方案1】：

我想你得到this 错误。

Twitter API 使用 UTC 时间，可能早于或晚于您的本地时间。

尝试从这里改变

# Get datetime for now and 7 days ago, correctly formatted for Twitter API
dtformat = '%Y-%m-%dT%H:%M:%SZ'
from datetime import datetime, timedelta
time = datetime.now()
start_time = time - timedelta(days=7)

# convert to strings
start_time, end_time = start_time.strftime(dtformat), time.strftime(dtformat)

到这里

# Get datetime for now and 7 days ago, correctly formatted for Twitter API
dtformat = '%Y-%m-%dT%H:%M:%SZ'
from datetime import datetime, timedelta
# time = datetime.now() gives you the local time whereas time = datetime.utcnow() 
# gives the local time in UTC. Hence now() may be ahead or behind which gives the 
# error

time = datetime.utcnow()
start_time = time - timedelta(days=7)

# Subtracting 15 seconds because api needs end_time must be a minimum of 10 
# seconds prior to the request time
end_time = time - timedelta(seconds=15)

# convert to strings
start_time, end_time = start_time.strftime(dtformat), 
end_time.strftime(dtformat)

【参考方案2】：

不确定这是否有帮助，但我收到了对以下 URL（我也在使用 Bearer 令牌）的良好响应，其中传递了 start_time、end_time 和粒度：

url_link = "https://api.twitter.com/2/tweets/counts/recent?query=(%23ethereum OR %23eth)&granularity=day&start_time=2021-11-23T00:00:00Z&end_time=2021-11-23T23:59:59Z"

def connect_to_endpoint(url, params):
     response = requests.get(url, auth=bearer_oauth, params=params)
     print(response.status_code)
     if response.status_code != 200:
           raise Exception(response.status_code, response.text)
     return response.json(
def main():
     json_response = connect_to_endpoint(url_link, )
     print(json.dumps(json_response, indent=4, sort_keys=True))

收到的回复：200
