Get json from request flask
提问by lads
Client code:
客户端代码：
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)
Server code:
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)
The problem is that my username and password are always None.
问题是我的用户名和密码总是无。
I also tried using:
我也尝试使用：
content = request.get_json(force = True)
password = content['pass']
and
和
request.form['user']
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.
当我打印内容时，我有： < Request ' http://127.0.0.1:5050/login' [POST]> 。所以我找不到从客户端发送的 json。
EDIT:
编辑：
I did add json.dumps and used request.get_json() and it worked
我确实添加了 json.dumps 并使用了 request.get_json() 并且它起作用了

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.
您发送的是表单编码数据，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})
Retrieve the data in Flask with:
使用以下命令检索 Flask 中的数据：
data = request.get_json()

I tried executing the same code that you have posted and I was able to fetch values for usernameand passwordinstead of None.
我尝试执行您发布的相同代码，并且能够获取username和 的值而password不是None.

My initial guess is that since you aren't setting the Content-Type header in your request Flask doesn't understand that it should be able to parse the data. Try adding Content-Type header with the value application/jsonand see if that gets you where you want.
我最初的猜测是，由于您没有在请求中设置 Content-Type 标头，因此 Flask 不明白它应该能够解析数据。尝试添加带有值的 Content-Type 标头，application/json看看是否可以让您到达您想要的位置。
Another thing to note is when I hit my login page the browser sets the Content-Type header to
application/x-www-form-urlencodedand encodes the data as user=asdf&passwd=asdf
另一件要注意的事情是，当我点击登录页面时，浏览器将 Content-Type 标头设置为
application/x-www-form-urlencoded并将数据编码为user=asdf&passwd=asdf
