好了昨天講完要做什麼今天要開始實作了

首先打開Day 9 Debug完的Code，然後開始實作吧

Create Notion Create Database Path

一開始可以先在main.go加上notion的相關路徑

func main() {
	r := gin.Default()

	c := controller.NewController()

	v1 := r.Group("/api/v1")
	{
		notion := v1.Group("/notion")
		{
			notion.POST("/createDatabase", c.CreateNotionDatabase)
		}
		...
	}
	...
	r.Run(":8080")
}

將route設定好了，gin取得這個連結的時候就會知道要到哪一個controller來找function

接著來寫CreateNotionDatabase這段

Create Notion Create Database

這邊我先上Code，再來稍微解釋一下
controller/notion.go

package controller

import (
	"log"

	"github.com/gin-gonic/gin"
	"github.com/spf13/viper"
	"github.com/swaggo/swag/example/celler/handler"
)

// CreateNotionDatabase godoc
//
//	@Summary		Create a new Notion Database
//	@Description	Creates a database as a subpage in the specified parent page, with the specified properties schema. Currently, the parent of a new database must be a Notion page or a wiki database.
//	@Tags			notion
//	@Accept			json
//	@Produce		json
//	@Success		200		{string}	string			"success"
//	@Failure		400		{string}	string			"fail"
//	@Router			/api/v1/notion/createDatabase [post]
func (c *Controller) CreateNotionDatabase(ctx *gin.Context) {
	client := handler.NewClient()
	header := map[string]string{
		"Authorization":  "[Your Secret]",
		"Notion-Version": "2022-06-28",
		"Content-Type":   "application/json",
	}
	body := []byte(`{
		"is_inline": true,
		"parent": {
			"type": "page_id",
			"page_id": "[Your Page Id]"
		},
		"icon": {
			"type": "emoji",
				"emoji": "📝"
		  },
		  "cover": {
			  "type": "external",
			"external": {
				"url": "https://website.domain/images/image.png"
			}
		  },
		"title": [
			{
				"type": "text",
				"text": {
					"content": "Grocery List",
					"link": null
				}
			}
		],
		"properties": {
			"Name": {
				"title": {}
			},
			"Description": {
				"rich_text": {}
			},
			"In stock": {
				"checkbox": {}
			},
			"Food group": {
				"select": {
					"options": [
						{
							"name": "🥦Vegetable",
							"color": "green"
						},
						{
							"name": "🍎Fruit",
							"color": "red"
						},
						{
							"name": "💪Protein",
							"color": "yellow"
						}
					]
				}
			},
			"Price": {
				"number": {
					"format": "dollar"
				}
			},
			"Last ordered": {
				"date": {}
			},
			"Store availability": {
				"type": "multi_select",
				"multi_select": {
					"options": [
						{
							"name": "Duc Loi Market",
							"color": "blue"
						},
						{
							"name": "Rainbow Grocery",
							"color": "gray"
						},
						{
							"name": "Nijiya Market",
							"color": "purple"
						},
						{
							"name": "Gus's Community Market",
							"color": "yellow"
						}
					]
				}
			},
			"+1": {
				"people": {}
			},
			"Photo": {
				"files": {}
			}
		}
	}`)
	client.Post("https://api.notion.com/v1/databases", header, body)
}

由於swaggo是抓code中的註解，需要在controller上面打上一些註解

這邊先稍微講有用到的部分，有時間再詳細介紹

• Summary：路徑旁邊的內容
• Description：下面的說明
• Tags：上面的標籤
• Success：200 ok的時候要回傳的內容，這邊只有success
• Failure：400 的時候要回的內容，這邊只有failed
• Router：這隻API的路徑，路徑要跟上面main.go設定的一樣

至於在下面的CreateNotionDatabase function中，根據Day 7的Header跟Body還有url填進去

最後再用golang post的function就可以在Notion中順利產生Database

明天會講一下要怎麼喂Secret跟Post的內容，先show一下完成圖。
