从请求瓶获取json
问题描述:
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)
问题在于我的用户名和密码始终为无".
The problem is that my username and password are always None.
我也尝试使用:
content = request.get_json(force = True)
password = content['pass']
和
request.form['user']
当我打印内容时,我有:<请求' http://127.0.0.1:5050/login '[POST]>.所以我无法找到客户端发送的json.
When I print the content I have: < Request 'http://127.0.0.1:5050/login' [POST]> .So I cannot find the json send from the client.
我确实添加了json.dumps并使用了request.get_json()并有效
I did add json.dumps and used request.get_json() and it worked
答
您正在发送表单编码的数据,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.
You are sending form encoded data, not JSON. Just setting the content-type doesn't turn your request into JSON. Use json=
to send JSON data.
response = requests.post(url, json={"user": user,"pass": password})
使用以下命令检索Flask中的数据:
Retrieve the data in Flask with:
data = request.get_json()
