Question

我有一个Flask脚本，可以创建一个网站并动态打印一些数据。 -打印的数据应该来自另一个python脚本。

我目前面临的问题是，如果我将执行python脚本的行放在执行Flask应用的行之前，它将运行Python脚本而不运行Flask；反之亦然。

Python脚本：

import websocket
from bitmex_websocket import Instrument
from bitmex_websocket.constants import InstrumentChannels
from bitmex_websocket.constants import Channels
import json

websocket.enableTrace(True)

sells = 0
buys = 0


channels = [
    InstrumentChannels.trade,
]


XBTUSD = Instrument(symbol='XBTUSD',
                    channels=channels)
XBTUSD.on('action', lambda msg: test(msg))


def test(msg):
    parsed = json.loads(json.dumps(msg))


    print(parsed)

XBTUSD.run_forever()

烧瓶脚本（注意：价格应为其他脚本的“解析”变量）：

# Start with a basic flask app webpage.
from flask_socketio import SocketIO, emit
from flask import Flask, render_template, url_for, copy_current_request_context
from random import random
from time import sleep
from threading import Thread, Event
import requests, json
import time

__author__ = 'slynn'

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
app.config['DEBUG'] = True

#turn the flask app into a socketio app
socketio = SocketIO(app)

#random number Generator Thread
thread = Thread()
thread_stop_event = Event()

class RandomThread(Thread):
    def __init__(self):
        self.delay = 1
        super(RandomThread, self).__init__()

    def randomNumberGenerator(self):
        while not thread_stop_event.isSet():
            socketio.emit('newnumber', {'number': parsed}, namespace='/test')
            sleep(self.delay)

    def run(self):
        self.randomNumberGenerator()


@app.route('/')
def index():
    #only by sending this page first will the client be connected to the socketio instance
    return render_template('index.html')

@socketio.on('connect', namespace='/test')
def test_connect():
    # need visibility of the global thread object
    global thread
    print('Client connected')

    #Start the random number generator thread only if the thread has not been started before.
    if not thread.isAlive():
        print("Starting Thread")
        thread = RandomThread()
        thread.start()

@socketio.on('disconnect', namespace='/test')
def test_disconnect():
    print('Client disconnected')


if __name__ == '__main__':
    socketio.run(app)

使用internals_type：

将python脚本（例如using System; using System.Threading.Tasks; using System.IO; using System.Collections.Concurrent; namespace Test { class Program { static void Main(string[] args) { GetFilesOnRoot("*"); Console.ReadLine(); } private static ConcurrentBag<string> FilesBag; private static void GetFilesOnRoot(string filter) { FilesBag = new ConcurrentBag<string>(); DirectoryInfo dirRoot = new DirectoryInfo("/"); GetDirTree(dirRoot, "*"); } private static void GetDirTree(DirectoryInfo dr, string filter) { FileInfo[] files = null; DirectoryInfo[] subDirs = null; try { files = dr.GetFiles(filter + ".*"); } catch(Exception) { } if (files != null) { Parallel.ForEach(files, (FileInfo item) => { FilesBag.Add(item.Name); }); subDirs = dr.GetDirectories(); Parallel.ForEach(subDirs, (DirectoryInfo item) => { GetDirTree(item,filter); }); } } public static async Task GetFilesOnRootAsync(string filter) { await Task.Run(() => { GetFilesOnRoot(filter); }); } } }）生成的内容包装到函数中。
将其放置在与import或website_generator.py相同的目录中。
在app.py中使用flask.py
使用from website_generator import function_name

您可以使用其他功能，例如flask.py等；尽管他们可能不会给您答复。

使用function_name()的示例：

subprocess.call

尝试一下：

from flask import Flask

app = Flask(__name__)

@app.route('/')
def run_script():
    file = open(r'/path/to/your/file.py', 'r').read()
    return exec(file)

if __name__ == "__main__":
    app.run(debug=True)
