问题描述
我想将flask应用程序用作lambda函数和无服务器框架，以将其部署在 AWS 平台上。 我想知道如何使用 boto3 从 swagger 文件在 API GATEWAY 服务上创建 REST API 代理请求到新创建的api。
因此，主要目标是使用无服务器框架部署flask lambda函数（如示例belove 所示），并且将其网关用作起点。然后它应该能够接收：
-
在 / create 路径上的
-
POST 请求，从 swagger文件
在API GATEWAY上创建新的API
在 api / {api} 上的 -
GET 请求可以通过POST请求访问以前创建的API
进一步的解释：
比方说，在api网关上启动api是 test.com （部署了如前所述的无服务器框架和flask lambda功能）。 / p>
通过 / create 上的POST请求通过POST请求发送swagger文件 swagger-pets.yaml （显示为belove的完整文件）网关称为 pet-store 。
现在应该可以调用该宠物商店API并将其用作：
-
GET test.com/api/pet-store/pet/{petID}-返回带有已传递ID的宠物
-
POST /test.com/api/pet-store/pet-添加新宠物
etc（与示例swagger petstore服务器https://editor.swagger.io/相同）。
我设法仅使用boto3 import_rest_api 方法从示例swagger文件创建（导入）API到api网关，但是它仅在api网关上添加了资源（路径），我不知道如何使用它。
烧瓶代码应如下所示：
# app.py
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
@app.route("/create",methods=["POST"])
def create():
# creates api on api gateway from swagger file using boto3
@app.route("/api/<path:subpath>",methods=["GET","POST"])
def proxy(subpath):
# proxy to any api gateway
无服务器框架代码示例：
# serverless.yml
service: serverless-flask

- serverless-python-requirements
