AWS API网关发布请求返回403被禁止

我有一个场景，我需要使用登录API来检索AWS access_key_id，secret_key，session_token和ID令牌 .

有了这组数据，我需要签署请求才能使用ruby http / net将post请求调用到需要AWS身份验证的其他API

问题是请求设法在Postman中完成，但是当它在ruby上执行时，它会失败 .

我正在使用这个宝石'aws-sdk'，'〜> 3'

和以下代码来检索登录，它的工作原理

require 'net/http'
require 'uri'
require 'json'
require 'openssl'
require 'cgi'


uri = URI.parse("https://EXAMPLE.execute-api.us-east-1.amazonaws.com/live/setup/cognito/login")
login_request = Net::HTTP::Post.new(uri)
login_request.content_type = "application/json"
login_request.body = JSON.dump({
  "username" => "USERNAME",
  "password" => "PASSWORD"
})

req_options = {
  use_ssl: uri.scheme == "https",
}

response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
  http.request(login_request)
end


login_json_response = JSON.parse response.body

然后以下设置签名并调用失败的POST请求并返回403禁止

signer = Aws::Sigv4::Signer.new(
  service: 'execute-api',
  region: 'us-east-1',
  access_key_id: login_json_response['access_key_id'],
  secret_access_key: login_json_response['secret_key'],
  session_token: login_json_response['session_token'],
  apply_checksum_header: false
)

signature = signer.sign_request(
  http_method: 'POST',
  url: 'https://EXAMPLE.execute-api.us-east-1.amazonaws.com/live/orders/suppliers',
  headers: {
    'id_token' => login_json_response['id_token'],
    'content_type' => "application/json"
  }
)


require 'net/http'
require 'uri'

supplier_uri = URI.parse("https://EXAMPLE.execute-api.us-east-1.amazonaws.com/live/orders/suppliers")
supplier_request = Net::HTTP::Post.new(supplier_uri)
supplier_request['Content-Type'] = "application/json"
supplier_request["Authorization"] = signature.headers['authorization']
supplier_request["X-Amz-Date"] = signature.headers['x-amz-date']
supplier_request["X-Amz-Security-Token"] =  signature.headers['x-amz-security-token']
supplier_request["id_token"] = login_json_response['id_token']

req_options = {
  use_ssl: supplier_uri.scheme == "https",
}

supplier_response = Net::HTTP.start(supplier_uri.hostname, supplier_uri.port, req_options) do |http|
  http.request(supplier_request)
end

错误消息是“我们计算的请求签名与您提供的签名不匹配 . 请检查您的AWS秘密访问密钥和签名方法 . 有关详细信息，请参阅服务文档 . ”

上面有什么错误的配置吗？谁能帮我这个？

-----编辑-----这里我附上了Postman的导出卷曲请求
