Question

我正在尝试生成令牌以对我对iTunes Connect API的请求进行签名。那是我的Ruby文件：

require "jwt"
require 'openssl'

ISSUER_ID = "my issuer string"
KEY_ID = "my key id string"

key_file = File.read('my p8 file containing my private key') # Located at the same folder than my ruby file
private_key = OpenSSL::PKey::RSA.new(key_file)

payload = {
      'iss': ISSUER_ID,
      'exp': 1528408800,
      'aud': 'appstoreconnect-v1'
  }

header = {
      'alg': 'ES256',
      'kid': KEY_ID,
      'typ': 'JWT'
  }

  jwt = JWT.encode(payload, private_key, algorithm='ES256', header)
  puts jwt

如果运行此文件ruby jwt.rb，则会得到以下输出：

/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt/algos/ecdsa.rb:15：in sign'：undefined method group'for＃（NoMethodError）来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt/signature.rb:35:in sign' 来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt/encode.rb:39:in encode_signature' 来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt/encode.rb:47：位于encode_segments中来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt/encode.rb:20:in initialize' 来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt.rb:21：in new' 来自/Library/Ruby/Gems/2.3.0/gems/jwt-2.1.0/lib/jwt.rb:21:in编码' 来自jwt.rb：22：in'

很难从控制台输出中看出失败的原因，但是如果我使用RS256作为算法并省略标题，则脚本会成功生成令牌。

Answer 1

似乎是由于将RSA密钥与ECDSA加密算法结合使用引起的。要么使用RS256代替ES256，要么使用OpenSSL::PKey::EC代替OpenSSL::PKey::RSA（尽管如此，您可能需要一个新的私钥）。
