import requests,json
url_post = "http://127.0.0.1:5000/post"
data_data = {"name":"my name is POST_data"}
data_json = {"name":"my name is POST_json"}
res = requests.post(url_post,data=json.dumps(data_data),json=data_json)
print(res.text)

有data,那么json就不生效
1.json=data_json
request.get_data   b'{"name": "my name is POST_json"}'
request.get_json   {'name': 'my name is POST_json'}
2.json=json.dumps(data_json)
request.get_datab'"{\\"name\\": \\"my name is POST_json\\"}"'
request.get_json{"name": "my name is POST_json"}
3.data=data_data
request.form    ImmutableMultiDict([('name', 'my name is POST_data')])
4.data=json.dumps(data_data)
request.get_data b'{"name": "my name is POST_data"}'
