如何在AWS EC2上运行python代码，然后使用POST? [英] How can I run a python code on AWS EC2 and then use POST?

问题描述

让我说我有这个密码

s =int(input("Input a number "))

x = s+5 

print(x)

如何在EC2上运行它，然后使用flask通过POST获取输出，以便可以在前端使用它?

how do I run it on EC2 and then use flask to get the output using POST so I can use it on a front end ?

我想制作一个网页，用户可以在其中输入s，然后在后端输入一个index.py文件，该文件与AWS EC2通信(使用flask)以运行上面的python代码，然后将值x返回前端结束

I want to make a webpage where a user can input s and then the backend which is an index.py file that communicates with AWS EC2 (using flask) to run the python code above and then return the value x to the front end

推荐答案

烧瓶应用程序示例代码

#!/usr/bin/python
from flask import Flask, request, jsonify
from index import some_fun

app = Flask(_name_)


@app.route('/foo', methods=['POST'])
def foo():
    data = request.form.to_dict()
    function_response = some_fun(data['form_field'])
    print(function_response)
    return jsonify(data)

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

您想要从其中调用some_function的python脚本index.py

You python script, index.py from where you want call some_function

def some_fun(x):返回x + 5

在这里，我考虑到过帐请求是由多部分/表单数据组成的.如果您正在使用application/json进行发布请求然后

here i have considered post request is of multipart/form-data. if you are making post request with application/json then

data = request.json
