python - 如何通过 SSL 运行 Flask/Python3.x？

问题描述

当我加载页面时，浏览器显示“无法访问此站点”

我的代码：

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST']) 
def route1():
  return f'--- request received ----'

if __name__ == "__main__":
    # https://www.name-of-my-domain.com
    app.run(port='8443', ssl_context=('./mydir/name-of-my-domain.com.crt', './mydir/private.key'))

我也试过：

from flask import Flask, request, jsonify
from werkzeug.serving import run_simple

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST']) 
def route1():
    return f'--- request received ----'

if __name__ == "__main__":
    # https://www.name-of-my-domain.com
    run_simple('https://www.name-of-my-domain.com/', 8443, app, ssl_context=('./mydir/name-of-my-domain.com.crt', './mydir/private.key'))

并且：

import ssl
# ... as before for app ...
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
context.load_cert_chain('./mydir/name-of-my-domain.com.crt', './mydir/private.key')
run_simple('https://www.name-of-my-domain.com/', 8443, app, ssl_context=context)

但是对于最后两个，当我运行文件时出现错误：

File "bot.py", line 38, in <module>
    run_simple('https://www.name-of-my-domain.com', 8443, app, ssl_context=context)
  File "/usr/local/lib/python3.6/site-packages/werkzeug/serving.py", line 1052, in run_simple
    inner()

    fd=fd,

    self.socket.bind(self.server_address)

解决方案

我将其排序为主机'0.0.0.0'，它适用于所有三个代码示例（但 '127.0.0.1' 不起作用）
