Question

我正在尝试连接到 Binance API。

https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md

我被拒绝访问。我怀疑问题可能不是 'signature'

如果有人有向 Binance 签署剩余请求的经验，请指出我出错的正确方向。

error {"code":-1022,"msg":"Signature for this request is not valid."}

  def get_time
    endpoint = "/api/v1/time"
    uri = @url + endpoint
    uri = URI(uri)
    response = Net::HTTP.get(uri)
    data = JSON.parse(response)
    data["serverTime"]
  end

  def get_amount
    query = URI.encode_www_form("timestamp"=> get_time)
    signature = sig(query)
    query = URI.encode_www_form("timestamp"=> get_time, "signature" => signature)
    endpoint = "/api/v3/account"
    uri = @url + endpoint + '?' + query

    uri = URI(uri)
    req = Net::HTTP::Get.new(uri)
    req['X-MBX-APIKEY'] = @api_key

    res = Net::HTTP.start(uri.hostname, uri.port, :use_ssl => uri.scheme == 'https') do |http|
      http.request(req)
    end

    puts "Sig: #{signature}"
    puts "www: #{uri}" 
    res.body
  end

  def sig(query)
    digest = OpenSSL::Digest::SHA256.new
    OpenSSL::HMAC.hexdigest(digest, @api_secret, query)
  end

似乎您调用了 get_time 两次，所以这可能是您的问题，因为 signed request documentation 指示签名应包含您的所有查询参数和请求正文连接。当您第二次调用 get_time 时，时间戳已在您使用第一次时间戳创建签名后更改。

试试这个

  def get_amount
    timestamp = get_time
    query = URI.encode_www_form("timestamp"=> timestamp)
    signature = sig(query)
    query = URI.encode_www_form("timestamp"=> timestamp, "signature" => signature)
    endpoint = "/api/v3/account"
    uri = @url + endpoint + '?' + query

    uri = URI(uri)
    req = Net::HTTP::Get.new(uri)
    req['X-MBX-APIKEY'] = @api_key

    res = Net::HTTP.start(uri.hostname, uri.port, :use_ssl => uri.scheme == 'https') do |http|
      http.request(req)
    end

    puts "Sig: #{signature}"
    puts "www: #{uri}" 
    res.body
  end

附带说明一下，您的 get_time 方法可以是 1 行：

def get_time
  (Time.now.to_f * 1000).to_i.to_s
end
