JSON ウェブトークン（JWT）の作成

API: Drive (classic)

このドキュメントでは、Drive（クラシック）API について説明しています。Drive API を使用している場合は、「Drive の JWT ハウツーガイド」をご覧ください。

前提条件

始める前に、開発者ポータルでアクセスキーを作成して保存していることを確認してください。

続行するには、 「developer_id」、「key_id」、および「signing_secret」が必要です

JavaScript

npm install jsonwebtoken

Python

pip install pyjwt

Kotlin

gradle.properties:

    # JWT
    jjwtVersion=0.10.6

build.gradle.kts:

    dependencies {
        testImplementation(kotlin("test"))
        val jjwtVersion: String by project
        implementation("io.jsonwebtoken:jjwt-api:$jjwtVersion")
        implementation("io.jsonwebtoken:jjwt-impl:$jjwtVersion")
        implementation("io.jsonwebtoken:jjwt-jackson:$jjwtVersion")
    }

C#

dotnet add package System.IdentityModel.Tokens.Jwt

JWT の生成方法

JavaScript

const jwt = require('jsonwebtoken')

const data = {
  aud: 'doordash',
  iss: '{developer_id}',
  kid: '{key_id}',
  exp: Math.floor(Date.now() / 1000 + 60),
  iat: Math.floor(Date.now() / 1000),
}

const headers = { algorithm: 'HS256', header: { 'dd-ver': 'DD-JWT-V1' } }

const token = jwt.sign(data, Buffer.from('{signing_secret}', 'base64'), headers)

Python

import jwt.utils
import time
import math

token = jwt.encode(
    {
        "aud": "doordash",
        "iss": "{developer_id}",
        "kid": "{key_id}",
        "exp": str(math.floor(time.time() + 60)),
        "iat": str(math.floor(time.time())),
    },
    jwt.utils.base64url_decode("{signing_secret}"),
    algorithm="HS256",
    headers={"dd-ver": "DD-JWT-V1"})

PHP

function base64UrlEncode(string $data): string
{
    $base64Url = strtr(base64_encode($data), '+/', '-_');

    return rtrim($base64Url, '=');
}

function base64UrlDecode(string $base64Url): string
{
    return base64_decode(strtr($base64Url, '-_', '+/'));
}

$header = json_encode([
    'alg' => 'HS256',
    'typ' => 'JWT',
    'dd-ver' => 'DD-JWT-V1'
]);

$payload = json_encode([
    'aud' => 'doordash',
    'iss' => '{developer_id}',
    'kid' => '{key_id}',
    'exp' => time() + 60,
    'iat' => time()
]);

$base64UrlHeader = base64UrlEncode($header);
$base64UrlPayload = base64UrlEncode($payload);

$signature = hash_hmac('sha256', $base64UrlHeader . "." . $base64UrlPayload, base64UrlDecode({signing_secret}), true);
$base64UrlSignature = base64UrlEncode($signature);

$jwt = $base64UrlHeader . "." . $base64UrlPayload . "." . $base64UrlSignature;

Kotlin

import io.jsonwebtoken.Header
import io.jsonwebtoken.Jwts
import io.jsonwebtoken.io.Decoders
import io.jsonwebtoken.security.Keys
import java.security.Key
import java.time.ZoneOffset
import java.time.ZonedDateTime
import kotlin.collections.HashMap

val claims = HashMap<String, Any?>();

claims["aud"] = "doordash";
claims["iss"] = "{developer_id}";
claims["kid"] = "{key_id}";
claims["exp"] = ZonedDateTime.now(ZoneOffset.UTC).plusMinutes(1).toEpochSecond()
claims["iat"] = ZonedDateTime.now(ZoneOffset.UTC).toEpochSecond();

val keyBytes = Decoders.BASE64URL.decode("{signing_secret}")
val key: Key = Keys.hmacShaKeyFor(keyBytes)

val jwt: String = Jwts.builder()
    .setHeaderParam("dd-ver", "DD-JWT-V1")
    .setHeaderParam("typ", "JWT")
    .setClaims(claims)
    .signWith(key)
    .compact();

C#

using Microsoft.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;

var decodedSecret = Base64UrlEncoder.DecodeBytes("{signing_secret}");
var securityKey = new SymmetricSecurityKey(decodedSecret);
var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
var header = new JwtHeader(credentials);
header["dd-ver"] = "DD-JWT-V1";

var payload = new JwtPayload(
    issuer: "{developer_id}",
    audience: "doordash",
    claims: new List<Claim> { new Claim("kid", "{key_id}") },
    notBefore: null,
    expires: System.DateTime.UtcNow.AddSeconds(60),
    issuedAt: System.DateTime.UtcNow);

var securityToken = new JwtSecurityToken(header, payload);
var token = new JwtSecurityTokenHandler().WriteToken(securityToken);
