flask不指定host的话flask默许运转在127.0.0.1,端口是:5000 不许被外网和同一个局域网的其余呆板考察,(即使向要被考察须要树立host地方0.0.0.0)

from flask import Flask

from flask import request

app = Flask(__name__)

@app.route('/')

def index():

user_agent=request.headers.get('User_Agent')

return 'user_agent is %s' %user_agent

if __name__ == '__main__':

app.run(

host='0.0.0.0',

port= 5000,

debug=True

)

不妨窜改上头的端口和长机ip,再启用!
