How To Convert Escaped Array of Objects String Into Map in Go Lang

Let's assume you have array of objects in escaped string format and you want to convert them to map[string]string we can use the below code format.

package main

import (
	"encoding/json"
	"fmt"
)

type GenericHeader struct {
	Key   string `json:"key"`
	Value string `json:"value"`
}

func main() {
	
	escapeJsonString := "[{\"value\":\"123456\",\"key\":\"hash-key\"},{\"value\":\"srinivas4sfdc\",\"key\":\"requesting-host\"},{\"value\":\"token-based-authorization-policy\",\"key\":\"policy-name\"},{\"value\":\"application/x-www-form-urlencoded\",\"key\":\"Content-Type\"}]"
	fmt.Println("Input data:", string(escapeJsonString))
	var headers []GenericHeader
	err := json.Unmarshal([]byte(escapeJsonString), &headers)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	headerMap := make(map[string]string)
	for _, header := range headers {
		fmt.Println(header.Key + ".." + header.Value)
		headerMap[header.Key] = header.Value
	}

	fmt.Println("Final Map Data==>",headerMap)
}

Input Data:

"[{\"value\":\"123456\",\"key\":\"hash-key\"},{\"value\":\"srinivas4sfdc\",\"key\":\"requesting-host\"}]"

Output Data:

map[requesting-host:srinivas4sfdc hash-key:123456]
