flask接收json数据

1. 利用flask的request.form()方法接收：

import json

from flask import Flask

app = Flask(__name__)


@app.route('/')
def index():
    data = request.form['data']  # 获取值
    return json.dumps(data,ensure_ascii=False)

2. 利用flask的request.get_data()方法接收

from flask import Flask
app = Flask(__name__)

@app.route("/check/custom/file",methods=["POST"])
def check_custom_file():
    set_config = request.get_data()
    if set_config is None or set_config == "":
        return json_error(403,"Parameter set_config can not be empty.")
    set_config = json.loads(set_config)
    print(set_config)                                                                                                                                   
    return jsonify(status="success")

3. 利用flask的request.args.to_dict()

@app.route('/add2',methods=['GET'])

def Add2():
    get_data = request.args.to_dict()# 获取传入的params参数
    num1 = get_data.get('num1')
    num2 = get_data.get('num2')
    return json.dumps(int(num2) + int(num1),ensure_ascii=False)

requests发送post请求发送json数据

1. 将json格式的数据转换成字典类型的数据，调用json.dumps()方法完成传递

import requests
import json

url = 'https://openapi.vmall.com/mcp/offlineshop/getShopList'
headers = {
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/80.0.3987.163 Safari/537.36'
}
# 将json类型的数据转换成字典类型的数据
data = {
"portal":2,"lang":"zh-CN","country":"CN","brand":1,"province":"山西","city":"太原","pageNo":1,"pageSize":20
}

# 调用json.dumps()方法，将数据以json格式传递
response = requests.post(url=url,headers=headers,data=json.dumps(data))
page_text = response.text

print(page_text)

2. 直接使用post方法，给参数json传入json类型的数据

import requests

url = "http://172.16.12.131:8888/check/custom/file"
header = {
    "aaaa": token
}
data = {
    "aaa":True,"bbb":False
}
res = requests.post(url=url,headers=header,json=data)

#print(res.content,res.status_code)
print(res.text,res.status_code)
