写个golang可以解析map[_id:map[_data:8263B4EB63000000062B022C0100296E5A1004C3E4524B77B64630AC204C7469FAED7F46645F6964006463B4EB636EBBDB249F2ED2770004] clusterTime:{1672801123 6} documentKey:map[_id:ObjectID("63b4eb636ebbdb249f2ed277")] fullDocument:map[OwnerID:123 QuotaSize:104857600 _id:ObjectID("63b4eb636ebbdb249f2ed277") directory:/buckets name:123_test1] ns:map[coll:UserQuotaConfig db:filer3] operationType:insert wallTime:1672801123879]中fullDocument的OwnerID、name、QuotaSize的方法

你可以这样解析出 map 中的 fullDocument 中的 OwnerID、name、QuotaSize：

package main

import (
	"fmt"
	"reflect"
)

func main() {
	m := map[string]interface{}{
		"_id": map[string]interface{}{
			"_data": "8263B4EB63000000062B022C0100296E5A1004C3E4524B77B64630AC204C7469FAED7F46645F6964006463B4EB636EBBDB249F2ED2770004",
		},
		"clusterTime": map[string]interface{}{
			"1672801123": 6,
		},
		"documentKey": map[string]interface{}{
			"_id": "ObjectID(\"63b4eb636ebbdb249f2ed277\")",
		},
		"fullDocument": map[string]interface{}{
			"OwnerID":      123,
			"QuotaSize": 104857600,
			"_id":         "ObjectID(\"63b4eb636ebbdb249f2ed277\")",
			"directory":   "/buckets",
			"name":        "123_test1",
		},
		"ns": map[string]interface{}{
			"coll": "UserQuotaConfig",
			"db":   "filer3",
		},
		"operationType": "insert",
		"wallTime":      1672801123879,
	}

	// 取出 fullDocument
	fullDocument, ok := m["fullDocument"].(map[string]interface{})
	if !ok {
		fmt.Println("fullDocument not found")
		return
	}

	// 取出 OwnerID
	OwnerID, ok := fullDocument["OwnerID"].(int)
	if !ok {
		fmt.Println("OwnerID not found")
		return
	}
	fmt.Println("OwnerID:", OwnerID)

	// 取出 name
	name, ok := fullDocument["name"].(string)
	if !ok {
		fmt.Println("name not found")
		return
	}
	fmt.Println("name:", name)

	// 取出 QuotaSize
	QuotaSize, ok := fullDocument["QuotaSize"].(int)
	if !ok {
		fmt.Println("QuotaSize not found")
		return
	}
	fmt.Println("QuotaSize:", QuotaSize)
}

在这个例子中，我们首先将 map 赋值给了变量 m。然后使用类型断言取出了 fullDocument 并将其赋
