我是Python新手。尝试使用Python requests
模块自动化一些痛苦的API调用。非常接近,但不知道如何将时间戳列表作为request parameters
传递
示例:生成lastModified
时间戳列表
import datetime
from datetime import datetime, timedelta
earliest_ts_str = '2020-10-01T15:00:00Z'
earliest_ts_obj = datetime.strptime(earliest_ts_str, timestamp_format)
#bottom_ts_obj = earliest_ts_obj.replace(second=0, microsecond=0, minute=0)
latest_ts_str = '2020-10-01T23:00:00Z'
latest_ts_obj = datetime.strptime(latest_ts_str, timestamp_format)
ts_raw = []
while earliest_ts_obj < latest_ts_obj:
ts_raw.append(earliest_ts_obj)
earliest_ts_obj += timedelta(hours=1)
ts_raw.append(latest_ts_obj)
ts_formatted = [d.strftime('%Y-%m-%dT%H:%M:%SZ') for d in ts_raw]
ts_formatted
结果:
['2020-10-01T15:00:00Z',
'2020-10-01T16:00:00Z',
'2020-10-01T17:00:00Z',
'2020-10-01T18:00:00Z',
'2020-10-01T19:00:00Z',
'2020-10-01T20:00:00Z',
'2020-10-01T21:00:00Z',
'2020-10-01T22:00:00Z',
'2020-10-01T23:00:00Z']
示例2:创建request
调用
lastModifiedStart
参数传递?和lastModifiedEnd
参数传递?import requests
method = 'get'
base_url = 'https://sandbox-api.com/'
api_type = 'items'
api_version = '/v1/'
api_path = api_type + api_version
api_key = 'myKey'
full_url = base_url + api_path
def make_historic_calls(last_mod_start, last_mod_end):
last_mod_start = for ts in ts_formatted: ts
last_mod_end = for ts in ts_formatted: ts
parameters = {'api_key':api_key, 'lastModifiedStart': last_mod_start, 'lastModifiedEnd': last_mod_end}
auth_header = {'Authorization': 'Basic <base64EncodedStringHere>'}
resp_raw = requests.request(method, full_url, headers=auth_header, params=parameters)
resp_processed = json.loads(resp_raw.content)
resp_pretty = json.dumps(resp_processed, indent=2, sort_keys=True)
return print(pretty)
test = make_historic_calls(ts_formatted, ts_formatted)
我知道这不是一个容易的解决办法(我花了好几天才走到这一步),但任何关于如何解决这一问题的指导都将不胜感激
多谢各位
编辑1:此调整功能非常有效
def make_historic_calls(ts_formatted):
for last_mod_start, last_mod_end in zip(ts_formatted, ts_formatted[1:]):
parameters = {'api_key':api_key, 'lastModifiedStart': last_mod_start, 'lastModifiedEnd': last_mod_end}
auth_header = {'Authorization': 'Basic <base64EncodedString>'}
resp_raw = requests.request(method, full_url, headers=auth_header, params=parameters)
print(f'{resp_raw.url} Status Code: {str(resp_raw.status_code)}')
return print(resp_raw)
test = make_historic_calls(ts_formatted)
从列表中提取连续项对的标准技巧是:
因此,您的代码需要类似于:
我希望我已经正确地理解了你想做什么
然后您可以按如下方式使用它:
希望这有帮助
编辑: 我不确定您是否希望通过重叠或不重叠的对来传递变量,是否希望它们像(0,1)(1,2)(2,3)一样重叠。。。而不是(0,1)(2,3)(4,5)。。。然后使用下面的“chunks”版本:
