如何使用 Python 处理 POST 请求？

Question

我正在尝试设置一个可以侦听和处理 POST 请求的小型 Python 3.8 脚本。我想收听来自 Trello 的 POST，然后只记录数据。我阅读的每个视频或指南都在展示如何处理来自 HTML 表单的 POST 请求。

Trello 示例：

{
   "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",
      "closed":false,
      "idOrganization":"4e1452614e4b8698470000e0",
      "pinned":true,
      "url":"https://trello.com/b/nC8QJJoZ/trello-development",
      "prefs": {
         "permissionLevel":"public",
         "voting":"public",
         "comments":"public",
         "invitations":"members",
         "selfJoin":false,
         "cardCovers":true,
         "canBePublic":false,
         "canBeOrg":false,
         "canBePrivate":false,
         "canInvite":true
      },
      "labelNames": {
         "yellow":"Infrastructure",
         "red":"Bug",
         "purple":"Repro'd",
         "orange":"Feature",
         "green":"Mobile",
         "blue":"Verified"
      }
   }
}

Answer 1

我会考虑使用像 Flask 这样的轻量级 Web 应用程序框架。使用 Flask，您可以在 Python 中创建一个简单的服务器端脚本来侦听 POST 请求并处理数据。

示例：

首先，安装 Flask：pip install flask.

然后，这是一个示例脚本：

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，但要运行它在生产中，您应该参考 Flask Deployment Options。

如果你想收听 POST 请求，那么你需要某种网络服务器

您可以通过 flask、django 或任何其他框架工作使用 python 获取网络服务器另一种选择是使用 python 库 "http.server"

这里我制作了简单的 Python 3 HTTP 服务器用于记录所有 GET 和 POST 请求
