Python使用POST发送HTTP请求出现Failed to decode JSON object: Expecting value: 错误

import requests

url = 'http://***.***.***.***:****/ppp'
headers = {'Content-Type': 'application/json'}
# headers = {'Content-Type': 'text/plain'}
postdata = {
    "start_time": 1536758128,
    "end_time": 1536761728
}
result = requests.post(url=url, data=postdata, headers=headers)
print(result.text)

此时需要将postdata转换为json格式，解决方法有两个。

方法一：

>>> import json

>>> url = 'https://api.github.com/some/endpoint'
>>> payload = {'some': 'data'}

>>> r = requests.post(url, data=json.dumps(payload))

方法二：

>>> url = 'https://api.github.com/some/endpoint'
>>> payload = {'some': 'data'}

>>> r = requests.post(url, json=payload)
