Question

我刚刚第一次进入Flask并尝试使用它来创建一个API，它有GET，POST和DELETE路由来管理网址黑名单。

经过一段时间后，POST路由会给我一个错误：＆＃34;无法得到任何回复。＆＃34;奇怪的是，我的GET和DELETE路线仍然可以正常工作。我试图让一些伐木进行，但是天堂还没有得到多少。我很感激任何帮助！

这是我的应用：

@Override
public void setTitle(final CharSequence title) {
    toolBar.postDelayed(new Runnable() {
        @Override
        public void run() {
            MainActivity.super.setTitle(title);
        }
    }, 200);
}

这是我的配置文件：

from flask import Flask, request
from flask_cors import CORS, cross_origin
from flask_restful import Resource, Api
import pickle

app = Flask(__name__)
app.config['DEBUG'] = True
CORS(app)


@app.route("/get-blacklist")
def loadblacklist():
    blacklist = pickle.load( open( "blacklist.p", "rb" ) )
    return dumps(blacklist)


@app.route("/post-blacklist", methods=['POST'])
def puturl():
    # Get and clean URL
    url = request.form['url']
    url = sanitise(url)

    # Load the pickle
    blacklist = list(pickle.load( open( "blacklist.p", "rb" ) ))

    # Check if it's already in there
    if url not in blacklist:
        blacklist.append(url)

    # Save the pickle
    pickle.dump( blacklist, open( "blacklist.p", "wb" ) )

    return 'You posted {}'.format(url)


@app.route("/remove-blacklist", methods=['DELETE'])
def removeurl():
    # Get and clean the URL
    url = request.form['url']
    url = sanitise(url)

    # Load the pickle
    blacklist = list(pickle.load( open( "blacklist.p", "rb" ) ))

    # Remove if its in there
    if url in blacklist:
        blacklist.remove(url)

    # Save the pickle
    pickle.dump( blacklist, open( "blacklist.p", "wb" ) )

    return 'You removed {}'.format(url)


def sanitise(url):
    # Sanitise
    url = url.lower()
    url = url.replace('www.', '')
    url = url.replace('http://', '')
    url = url.replace('https://', '')
    if url[-1] == '/':
        url = url[:-1]
    return url


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

以下是我用来启动工人的命令：

import os

bind = '0.0.0.0:8000'
workers = 3
backlog = 2048
worker_class = "sync"
debug = False
proc_name = 'gunicorn.proc'
pidfile = './gunicorn.pid'
logfile = './debug.log'
loglevel = 'debug'
timeout = 1000

我在POST路线中看不到会导致这种情况发生特别不同的事情 - 特别是因为它似乎有效了一段时间。

我在一个virtualenv，Flask，在apache2和Ubuntu 14.04上使用gunicorn运行Python 3.

任何帮助将不胜感激！

我发现解决方案是使用with语句打开我的pickle文件。似乎可以帮助解决任何开/关冲突。
