How To Convert Array of Escaped Object String to String Object In Go Language

In our previous post we have learn how to convert the array/list of string objects into map and now with help of this map we can convert the array of objects in string format single object string.

Source Code:

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)
	marshalData, err := json.Marshal(headerMap)
	if err != nil {
		fmt.Println(err.Error())
		return
	}
	fmt.Println("marshalData==>", marshalData)
	fmt.Println("Final Object String ==>", string(marshalData))
}

Input Data String:

"[{\"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\"}]"

Output Data String:

{"Content-Type":"application/x-www-form-urlencoded","hash-key":"123456","policy-name":"token-based-authorization-policy","requesting-host":"srinivas4sfdc"}

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]
