python - Webpy属性错误 ' header key'

Question

我最近在我的 ubuntu 机器上下载了 webpy，目前我在使用它的 POST 功能时遇到了问题。这是我的代码:

#! /usr/bin/env python

import web,interface

urls = (
    '/', 'index'
)

class index(object):
    def POST(self):
        data = web.input()
        interface.interfaceModule(data.decider)
    return "SENT TO INTERFACE"


if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()

interface 只是另一个接收 POST 值并通过串行将其发送到 Arduino 的类。

这是错误输出:

我使用 Chromium 应用程序:POST-MAN 使用指定的 key 和任意值发送了 post 请求。

Answer 1

此错误意味着您发送了错误的请求 - 您没有在 POST 中发送 decider。

尝试

import requests

r = requests.post('http://localhost:8080', data={'decider':'Hello World'})

print(r.text)
