从请求瓶中获取json

Question

客户代码:

import requests
import json

url = 'http://127.0.0.1:5050/login'
user = "newUser"
password = "password"
headers = {'content-type': 'application/json'}
response = requests.post(url, data={"user": user,"pass": password}, headers = headers)

服务器代码:

from flask import Flask, request, make_response

app = Flask(__name__)


@app.route('/login', methods=['GET','POST'])
def login():    
 if request.method == 'POST':

    username = request.form.get("user")
    password = request.form.get("pass")
    //more code
    return make_response("",200)

if __name__ == "__main__":
     app.run(host = "127.0.0.1", port = 5050)

问题是我的用户名和密码始终为None.

我也试过用:

content = request.get_json(force = True) 
password = content['pass']

和

request.form['user']

当我打印我的内容时:<请求' http://127.0.0.1:5050/login '[POST]>.因此我无法从客户端找到json发送.

编辑:

我添加了json.dumps并使用了request.get_json()并且它有效

您正在发送表单编码数据,而不是JSON.仅设置内容类型不会将您的请求转换为JSON.使用json=发送JSON数据.

response = requests.post(url, json={"user": user,"pass": password})

使用以下方法检索Flask中的数据:

data = request.get_json()
