为了开始构建，我们提供了一组简单的插件，涵盖了不同的身份验证模式和用例。从我们简单的无身份验证待办事项列表插件到更强大的检索插件，这些示例让我们得以一窥我们希望通过插件实现的功能。

在开发过程中，你可以在你的计算机上本地运行插件，或者通过像GitHub Codespaces、Replit或CodeSandbox这样的云开发环境运行插件。

一、学习如何建立一个简单的待办事项列表插件没有认证

首先，定义一个manifest.json文件，包含以下字段:

{
  "schema_version": "v1",
  "name_for_human": "TODO Plugin (no auth)",
  "name_for_model": "todo",
  "description_for_human": "Plugin for managing a TODO list, you can add, remove and view your TODOs.",
  "description_for_model": "Plugin for managing a TODO list, you can add, remove and view your TODOs.",
  "auth": {
    "type": "none"
  },
  "api": {
    "type": "openapi",
    "url": "PLUGIN_HOSTNAME/openapi.yaml",
    "is_user_authenticated": false
  },
  "logo_url": "PLUGIN_HOSTNAME/logo.png",
  "contact_email": "dummy@email.com",
  "legal_info_url": "http://www.example.com/legal"
}

接下来，我们可以定义几个简单的Python端点，用于为特定用户创建、删除和获取待办事项列表项。

import json

import quart
import quart_cors
from quart import request

app = quart_cors.cors(quart.Quart(__name__), allow_origin="*")

_TODOS = {}

@app.post("/todos/<string:username>")
async def add_todo(username):
    request = await quart.request.get_json(force=True)
    if username not in _TODOS:
        _TODOS[username] = []
    _TODOS[username].append(request["todo"])
    return quart.Response(response='OK', status=200)

@app.get("/todos/<string:username>")
async def get_todos(username):
    return quart.Response(response=json.dumps(_TODOS.get(username, [])), status=200)

@app.delete("/todos/<string:username>")
async def delete_todo(username):
    request = await quart.request.get_json(force=True)
    todo_idx = request["todo_idx"]
    # fail silently, it's a simple plugin
    if 0 <= todo_idx < len(_TODOS[username]):
        _TODOS[username].pop(todo_idx)
    return quart.Response(response='OK', status=200)

@app.get("/logo.png")
async def plugin_logo():
    filename = 'logo.png'
    return await quart.send_file(filename, mimetype='image/png')

@app.get("/.well-known/ai-plugin.json")
async def plugin_manifest():
    host = request.headers['Host']
    with open("manifest.json") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/json")

@app.get("/openapi.yaml")
async def openapi_spec():
    host = request.headers['Host']
    with open("openapi.yaml") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/yaml")

def main():
    app.run(debug=True, host="0.0.0.0", port=5002)

if __name__ == "__main__":
    main()

最后，我们需要设置和定义OpenAPI规范，以匹配本地或远程服务器上定义的端点。您不需要通过规范公开API的全部功能，而是可以选择让ChatGPT只访问某些功能。

还有许多工具可以自动将服务器定义代码转换为OpenAPI规范，这样就不需要手动操作了。对于上面的Python代码，OpenAPI规范看起来像这样:

openapi: 3.0.1
info:
  title: TODO Plugin
  description: A plugin that allows the user to create and manage a TODO list using ChatGPT. If you do not know the user's username, ask them first before making queries to the plugin. Otherwise, use the username "global".
  version: 'v1'
servers:
  - url: PLUGIN_HOSTNAME
paths:
  /todos/{username}:
    get:
      operationId: getTodos
      summary: Get the list of todos
      parameters:
      - in: path
        name: username
        schema:
            type: string
        required: true
        description: The name of the user.
      responses:
        "200":
          description: OK
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/getTodosResponse'
    post:
      operationId: addTodo
      summary: Add a todo to the list
      parameters:
      - in: path
        name: username
        schema:
            type: string
        required: true
        description: The name of the user.
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/addTodoRequest'
      responses:
        "200":
          description: OK
    delete:
      operationId: deleteTodo
      summary: Delete a todo from the list
      parameters:
      - in: path
        name: username
        schema:
            type: string
        required: true
        description: The name of the user.
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/deleteTodoRequest'
      responses:
        "200":
          description: OK

components:
  schemas:
    getTodosResponse:
      type: object
      properties:
        todos:
          type: array
          items:
            type: string
          description: The list of todos.
    addTodoRequest:
      type: object
      required:
      - todo
      properties:
        todo:
          type: string
          description: The todo to add to the list.
          required: true
    deleteTodoRequest:
      type: object
      required:
      - todo_idx
      properties:
        todo_idx:
          type: integer
          description: The index of the todo to delete.
          required: true

二、学习如何使用服务级别认证构建一个简单的待办事项列表插件

首先，定义一个manifest.json文件，包含以下字段:

{
  "schema_version": "v1",
  "name_for_human": "TODO Plugin (service http)",
  "name_for_model": "todo",
  "description_for_human": "Plugin for managing a TODO list, you can add, remove and view your TODOs.",
  "description_for_model": "Plugin for managing a TODO list, you can add, remove and view your TODOs.",
  "auth": {
    "type": "service_http",
    "authorization_type": "bearer",
    "verification_tokens": {
      "openai": "758e9ef7984b415688972d749f8aa58e"
    }
  },
   "api": {
    "type": "openapi",
    "url": "https://example.com/openapi.yaml",
    "is_user_authenticated": false
  },
  "logo_url": "https://example.com/logo.png",
  "contact_email": "dummy@email.com",
  "legal_info_url": "http://www.example.com/legal"
}

请注意，服务级别身份验证插件需要验证令牌。该token是在ChatGPT web界面安装插件时生成的。

接下来，我们可以定义几个简单的Python端点，用于为特定用户创建、删除和获取待办事项列表项。端点还进行简单的身份验证检查，因为这是必需的。

import json

import quart
import quart_cors
from quart import request

app = quart_cors.cors(quart.Quart(__name__), allow_origin="*")

_SERVICE_AUTH_KEY = "TEST"
_TODOS = {}

def assert_auth_header(req):
    assert req.headers.get(
        "Authorization", None) == f"Bearer {_SERVICE_AUTH_KEY}"

@app.post("/todos/<string:username>")
async def add_todo(username):
    assert_auth_header(quart.request)
    request = await quart.request.get_json(force=True)
    if username not in _TODOS:
        _TODOS[username] = []
    _TODOS[username].append(request["todo"])
    return quart.Response(response='OK', status=200)

@app.get("/todos/<string:username>")
async def get_todos(username):
    assert_auth_header(quart.request)
    return quart.Response(response=json.dumps(_TODOS.get(username, [])), status=200)

@app.delete("/todos/<string:username>")
async def delete_todo(username):
    assert_auth_header(quart.request)
    request = await quart.request.get_json(force=True)
    todo_idx = request["todo_idx"]
    # fail silently, it's a simple plugin
    if 0 <= todo_idx < len(_TODOS[username]):
        _TODOS[username].pop(todo_idx)
    return quart.Response(response='OK', status=200)

@app.get("/logo.png")
async def plugin_logo():
    filename = 'logo.png'
    return await quart.send_file(filename, mimetype='image/png')

@app.get("/.well-known/ai-plugin.json")
async def plugin_manifest():
    host = request.headers['Host']
    with open("manifest.json") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/json")

@app.get("/openapi.yaml")
async def openapi_spec():
    host = request.headers['Host']
    with open("openapi.yaml") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/yaml")

def main():
    app.run(debug=True, host="0.0.0.0", port=5002)

if __name__ == "__main__":
    main()

最后，我们需要设置和定义OpenAPI规范，以匹配本地或远程服务器上定义的端点。通常，不管采用何种身份验证方法，OpenAPI规范看起来都是一样的。在创建OpenAPI规范时，使用自动OpenAPI生成器将减少错误的可能性，因此值得探索这些选项。

          description: The index of the todo to delete.
          required: true

三、学习如何构建一个简单的体育统计插件

这个插件是一个简单的体育统计API的例子。在考虑构建什么时，请记住我们的域名政策和使用政策。

首先，我们可以定义一个manifest.json文件

{
  "schema_version": "v1",
  "name_for_human": "Sport Stats",
  "name_for_model": "sportStats",
  "description_for_human": "Get current and historical stats for sport players and games.",
  "description_for_model": "Get current and historical stats for sport players and games. Always display results using markdown tables.",
  "auth": {
    "type": "none"
  },
  "api": {
    "type": "openapi",
    "url": "PLUGIN_HOSTNAME/openapi.yaml",
    "is_user_authenticated": false
  },
  "logo_url": "PLUGIN_HOSTNAME/logo.png",
  "contact_email": "dummy@email.com",
  "legal_info_url": "http://www.example.com/legal"
}

接下来，我们为一个简单的体育服务插件定义一个模拟API。

import json
import requests
import urllib.parse

import quart
import quart_cors
from quart import request

app = quart_cors.cors(quart.Quart(__name__), allow_origin="*")
HOST_URL = "https://example.com"

@app.get("/players")
async def get_players():
    query = request.args.get("query")
    res = requests.get(
        f"{HOST_URL}/api/v1/players?search={query}&page=0&per_page=100")
    body = res.json()
    return quart.Response(response=json.dumps(body), status=200)

@app.get("/teams")
async def get_teams():
    res = requests.get(
        "{HOST_URL}/api/v1/teams?page=0&per_page=100")
    body = res.json()
    return quart.Response(response=json.dumps(body), status=200)

@app.get("/games")
async def get_games():
    query_params = [("page", "0")]
    limit = request.args.get("limit")
    query_params.append(("per_page", limit or "100"))
    start_date = request.args.get("start_date")
    if start_date:
        query_params.append(("start_date", start_date))
    end_date = request.args.get("end_date")

    if end_date:
        query_params.append(("end_date", end_date))
    seasons = request.args.getlist("seasons")

    for season in seasons:
        query_params.append(("seasons[]", str(season)))
    team_ids = request.args.getlist("team_ids")

    for team_id in team_ids:
        query_params.append(("team_ids[]", str(team_id)))
    print(query_params)

    res = requests.get(
        f"{HOST_URL}/api/v1/games?{urllib.parse.urlencode(query_params)}")
    body = res.json()
    return quart.Response(response=json.dumps(body), status=200)

@app.get("/stats")
async def get_stats():
    query_params = [("page", "0")]
    limit = request.args.get("limit")
    query_params.append(("per_page", limit or "100"))
    start_date = request.args.get("start_date")
    if start_date:
        query_params.append(("start_date", start_date))
    end_date = request.args.get("end_date")

    if end_date:
        query_params.append(("end_date", end_date))
    player_ids = request.args.getlist("player_ids")

    for player_id in player_ids:
        query_params.append(("player_ids[]", str(player_id)))
    game_ids = request.args.getlist("game_ids")

    for game_id in game_ids:
        query_params.append(("game_ids[]", str(game_id)))
    res = requests.get(
        f"{HOST_URL}/api/v1/stats?{urllib.parse.urlencode(query_params)}")
    body = res.json()
    return quart.Response(response=json.dumps(body), status=200)

@app.get("/season_averages")
async def get_season_averages():
    query_params = []
    season = request.args.get("season")
    if season:
        query_params.append(("season", str(season)))
    player_ids = request.args.getlist("player_ids")

    for player_id in player_ids:
        query_params.append(("player_ids[]", str(player_id)))
    res = requests.get(
        f"{HOST_URL}/api/v1/season_averages?{urllib.parse.urlencode(query_params)}")
    body = res.json()
    return quart.Response(response=json.dumps(body), status=200)

@app.get("/logo.png")
async def plugin_logo():
    filename = 'logo.png'
    return await quart.send_file(filename, mimetype='image/png')

@app.get("/.well-known/ai-plugin.json")
async def plugin_manifest():
    host = request.headers['Host']
    with open("manifest.json") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/json")

@app.get("/openapi.yaml")
async def openapi_spec():
    host = request.headers['Host']
    with open("openapi.yaml") as f:
        text = f.read()
        text = text.replace("PLUGIN_HOSTNAME", f"https://{host}")
        return quart.Response(text, mimetype="text/yaml")

def main():
    app.run(debug=True, host="0.0.0.0", port=5001)

if __name__ == "__main__":
    main()

最后，我们定义OpenAPI规范:
