如何使用Python处理POST请求？

Question

我正在尝试设置一个小的Python 3.8脚本，它可以侦听和处理POST请求。我想听听Trello的帖子，然后记录数据。我阅读的每一个视频或指南都展示了如何处理来自HTML表单的POST请求

特雷罗举例：

{
   "action": {
      "id":"51f9424bcd6e040f3c002412",
      "idMemberCreator":"4fc78a59a885233f4b349bd9",
      "data": {
         "board": {
            "name":"Trello Development",
            "id":"4d5ea62fd76aa1136000000c"
         },
         "card": {
            "idShort":1458,
            "name":"Webhooks",
            "id":"51a79e72dbb7e23c7c003778"
         },
         "voted":true
      },
      "type":"voteOnCard",
      "date":"2013-07-31T16:58:51.949Z",
      "memberCreator": {
         "id":"4fc78a59a885233f4b349bd9",
         "avatarHash":"2da34d23b5f1ac1a20e2a01157bfa9fe",
         "fullName":"Doug Patti",
         "initials":"DP",
         "username":"doug"
      }
   },
   "model": {
      "id":"4d5ea62fd76aa1136000000c",
      "name":"Trello Development",
      "desc":"Trello board used by the Trello team to track work on Trello.  How meta!\n\nThe development of the Trello API is being tracked at https://trello.com/api\n\nThe development of Trello Mobile applications is being tracked at https://trello.com/mobile",

         "selfJoin":false,
         "cardCovers":true,
         "canBePublic":false,
         "canBeOrg":false,

      },
      "labelNames": {

   }
}

Answer 1

如果您想要监听POST请求，那么您需要某种Web服务器

您可以通过flask、django或任何其他框架使用python获得Web服务器 另一种选择是使用python库“http.server”

在这里，我创建了一个简单的Python3HTTP服务器，用于记录所有GET和POST请求

Answer 2

我将研究使用轻量级web应用程序框架，如Flask。使用Flask，您可以用Python创建一个简单的服务器端脚本来侦听POST请求并处理数据

例如：

首先，安装Flask:pip install flask

下面是一个示例脚本：

from flask import Flask, request

app = Flask(__name__)

@app.route('/', methods=['POST'])
def result():
    print(request.data)  # raw data
    print(request.json)  # json (if content-type of application/json is sent with the request)
    print(request.get_json(force=True))  # json (if content-type of application/json is not sent)

Flask包含一个开发服务器，但是要在生产环境中运行它，您应该参考Flask Deployment Options
