四: 传参json

# 传参数据格式 - 要求json
# 方法一
import requests

dict = {
        "a": None,
        "b": False,
        "c": 123,
        "d": "string",
        "tuple": (123, "str"),
        "subject_list" : ["English", 123, "Math"],
        "dict" : {
                "English" : 88,
                "Chinese" : 92,
                "Math" : 100
        }
}

url = "http://bin.org/post"
r = requests.post(url, json=dict) # 自动转换 : dict - json 


    
# 传参数据格式 - 要求json
# 方法二
import requests
import json

dict = {
        "a": None,
        "b": False,
        "c": 123,
        "d": "string",
        "tuple": (123, "str"),
        "subject_list" : ["English", 123, "Math"],
        "dict" : {
                "English" : 88,
                "Chinese" : 92,
                "Math" : 100
        }
}
