我正在尝试使用 rails 应用程序实现 Payfort 支付网关。但我收到以下响应消息:
"response_message":"Signature mismatch"
以下是我的尝试:
params = {command: "AUTHORIZATION",
currency: "USD",
access_code: "z7TfXF2xxxxxxxxxxxx",
merchant_identifier: "xoNbjDoq",
merchant_reference: "405",
language: "en",

token_name: "token_is_here",
expiry_date: "07/2023",
card_number: "5200421234563432",
card_security_code: "417",
card_holder_name: "Abc Xyz",
remember_me: "YES",
return_url: "http://lvh.me:3000/payments/test"}
params = params.except(:card_security_code, :card_number, :expiry_date, :card_holder_name, :remember_me)
params = params.sort.to_h
string = params.to_query(nil)
string = string.gsub! '&', ''
string = @@sha_request + string + @@sha_request
string = Digest::SHA256.hexdigest string
uri = URI.parse("https://sbpaymentservices.payfort.com/FortAPI/paymentApi")
header = {'Content-Type': 'application/json'}
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Post.new(uri.request_uri, header)
request.body = params.to_json
response = http.request(request)
