Node JS, JSON 문자열에 Base64 String을 올바르게 저장하는 방법은 무엇입니까?

Question

나는 몇 가지 속성을 가진 JSON을 생성해야 그 중 하나는 base64로 문자열입니다 :

{"password":"123456","key":"MIIIhQIBAzCCCD8GCSqGSIb3DQEHAaCCCDAEgggsMIAwgAYJKoZIhvcNA

"} 

난 그냥 내 base64로의 마지막 부분을 건너 뛴 :

이

var file = fs.readFileSync('myfile'); 
var request = { password: '123456', key: file.toString('base64')}; 
console.log(JSON.stringify(request)); 

그것은 나에게 JSON의 종류를 출력 이 질문에 문자열.

JSON 문자열을 생성했으며 유효하지 않습니다. 왜냐하면 base64 문자열에 구조에 이중 백 슬래시가 있기 때문입니다.

base64 속성을 사용하여 JSON 문자열을 올바르게 생성하는 방법은 무엇입니까?

내 생성 된 64 기수는 다음과 같습니다

그리고 여기에 무엇을 검증 말한다 :

Answer 1

당신의 접근 방식은 좋지만 Base64 문자열에는 백 슬래시를 사용할 수 없으며 나머지는 이스케이프 처리됩니다.

Base64 index Table : 

0 A 16 Q 32 g 48 w 
1 B 17 R 33 h 49 x 
2 C 18 S 34 i 50 y 
3 D 19 T 35 j 51 z 
4 E 20 U 36 k 52 0 
5 F 21 V 37 l 53 1 
6 G 22 W 38 m 54 2

이 screencap 보면, 당신이 당신의 문자열에 줄 바꿈을 가지고있는 것처럼 보이는, 그런 경우가 될 수 있을까? 여기서 손실이 있습니다 : http://prnt.sc/ddyq6y

Answer 2

btoa(string)이 나를 위해 일한 사용 :

var string = 'Some string'; 

// Encoding 
var encodedString = btoa(string); 
console.log(encodedString); // out: "SGVsbG8gV29ybGQh" 

// Decoding 
var decodedString = atob(encodedString); 
console.log(decodedString); // out: "Some string" 

경우가 작동 할 수 다음과 같이 사용 :

var Base64={_keyStr:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/=",encode:function(e){var t="";var n,r,i,s,o,u,a;var f=0;e=Base64._utf8_encode(e);while(f<e.length){n=e.charCodeAt(f++);r=e.charCodeAt(f++);i=e.charCodeAt(f++);s=n>>2;o=(n&3)<<4|r>>4;u=(r&15)<<2|i>>6;a=i&63;if(isNaN(r)){u=a=64}else if(isNaN(i)){a=64}t=t+this._keyStr.charAt(s)+this._keyStr.charAt(o)+this._keyStr.charAt(u)+this._keyStr.charAt(a)}return t},decode:function(e){var t="";var n,r,i;var s,o,u,a;var f=0;e=e.replace(/[^A-Za-z0-9+/=]/g,"");while(f<e.length){s=this._keyStr.indexOf(e.charAt(f++));o=this._keyStr.indexOf(e.charAt(f++));u=this._keyStr.indexOf(e.charAt(f++));a=this._keyStr.indexOf(e.charAt(f++));n=s<<2|o>>4;r=(o&15)<<4|u>>2;i=(u&3)<<6|a;t=t+String.fromCharCode(n);if(u!=64){t=t+String.fromCharCode(r)}if(a!=64){t=t+String.fromCharCode(i)}}t=Base64._utf8_decode(t);return t},_utf8_encode:function(e){e=e.replace(/rn/g,"n");var t="";for(var n=0;n<e.length;n++){var r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r)}else if(r>127&&r<2048){t+=String.fromCharCode(r>>6|192);t+=String.fromCharCode(r&63|128)}else{t+=String.fromCharCode(r>>12|224);t+=String.fromCharCode(r>>6&63|128);t+=String.fromCharCode(r&63|128)}}return t},_utf8_decode:function(e){var t="";var n=0;var r=c1=c2=0;while(n<e.length){r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r);n++}else if(r>191&&r<224){c2=e.charCodeAt(n+1);t+=String.fromCharCode((r&31)<<6|c2&63);n+=2}else{c2=e.charCodeAt(n+1);c3=e.charCodeAt(n+2);t+=String.fromCharCode((r&15)<<12|(c2&63)<<6|c3&63);n+=3}}return t}} 

// String 
var string = 'Some string'; 

// Encoding 
var encodedString = Base64.encode(string); 
console.log(encodedString); // out: "SGVsbG8gV29ybGQh" 

// Decoding 
var decodedString = Base64.decode(encodedString); 
console.log(decodedString); // Outputs: "some string" 

그런 다음 문자열을 Json에 저장할 수 있습니다.

Answer 3

JSON.stringify를 base64 텍스트 key: JSON.stringify(file.toString('base64'))에서 사용할 수 있습니다. 조심해. ,

var s="SYNJNYU/zIa//Zu3O3bp+XwH"; console.log(JSON.stringify(s)); 

출력

"SYNJNYU/zIa//Zu3O3bp+XwH" 

하지만

var s="SYNJNYU\zIa\\Zu3O3bp+XwH"; console.log(JSON.stringify(s)); 

출력

"SYNJNYUzIa\\Zu3O3bp+XwH"
