# Sanic with json Note: 還記得 Sanic 嗎？ 上次我們教 Sanic 只有教到 GET 怎麼用，這次來教 POST --- ```python= from sanic import Sanic from sanic.response import json app = Sanic() @app.route("/", methods=["GET", "POST"]) async def get(request): if request.method == "GET": return json({"message": "hello!"}) elif request.method == "POST": _ = { "type": str(type(request.json)), "body": request.json } return json(_) app.run(host="127.0.0.1", port=8000) ``` --- Insomnia 打開 首先測試 GET 回傳內容與程式碼相似 ```py return json({"message": "hello!"}) ```  --- 取得json特定的值 Note: request.json => dict --- ```python else if request.method == "POST": return json(request.json) ``` || \\/ ```python else if request.method == "POST": return json(request.json["text"]) ``` --- 結果  --- 現在 使用其他HTTP方法嘗試 嘗試不存在的 API 路徑 Note: 是不是發現被擋住了 而且不是json 接下來我們來替換原本的錯誤訊息 --- Sanic 會丟的例外 (exception) ```= NotFound MethodNotSupported ServerError ``` --- ```python= ...之前的import from traceback import format_exc from sanic.log import logger from sanic.exceptions import ( NotFound, MethodNotSupported, ServerError ) ...之前的app.route @app.exception(NotFound) async def on_404(request, ex): _ = {"message": "NOT_FOUND"} return json(_, status=404) @app.exception(MethodNotSupported) async def on_405(request, ex): _ = {"message": "METHOD_NOT_SUPPORTED"} return json(_, status=405)500 @app.exception(Exception) async def on_500(request, ex): _ = {"message": "INTERNAL_SERVER_ERROR"} logger.error("Error occured in {}: {}".format(request.url, ex)) logger.error(format_exc()) return json(_, status=500) ``` ---    --- 挑戰 做一個抽獎機 輸入格式為 json ```json= ["Isabelle", "Nook", "K.K. Slider", "Marbel"] ```  ---
