python - 从 flask 中的客户处获取时间

Question

所以我有一个 flask 服务器和客户端。我想将数据从客户端发送到服务器，并将时间戳作为消息的一部分。这是我的代码:

import os
import requests
import glob
import time 
import base64


url = 'http://0.0.0.0:5000/'
path = './10_mb'
folders = [f for f in glob.glob(path + '**/*', recursive = True)]


send = round(time.time() * 1000)

def load_data():

    for folder in folders:
        with open(folder, 'rb') as imageFile:
            image_s = {'file_image':open(folder, 'rb')}

    return image_s


def send_data():

    r = requests.post(url, files = load_data(), headers = {'ts': str(send)})

if __name__ == "__main__":

    send_data()

这是服务器

from flask import Flask
from flask import request
import time 


app = Flask(__name__)

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

def home():
    timeout = time.time() + 5  

    while True:
        test = 0
        if test ==5 or time.time() > timeout:
            break

    return 'Hello', 200



app.run(host='0.0.0.0', threaded = True, debug = True)

当我运行客户端时，从服务器端它不会打印来自客户端的时间戳。我的问题是，如何从客户端获取时间戳？抱歉，如果这是一个愚蠢的问题，我完全是个菜鸟。提前致谢

Flask request中有很多attr 。其中，headers 返回您的 POST 的 header 。因此添加 print(request.headers) 就可以了。

# in server side...
@app.route("/", methods = ['GET', 'POST'])
def home():
    timeout = time.time() + 5  

    while True:
        test = 0
        if test ==5 or time.time() > timeout:
            break
    print(request.headers)
    return 'Hello', 200


app.run(host='0.0.0.0', threaded = True, debug = True)

# Host: 0.0.0.0:5000
