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“签名”

如果有人有向 Binance 签署休息请求的经验，我将不胜感激。

错误 {"code":-1022,"msg":"此请求的签名无效。"}

  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

好像你打get_time了两次电话，所以这可能是你的问题，因为签名的请求文档表明签名应该包含你所有的查询参数和连接的请求正文。当您get_time第二次调用时，时间戳在您使用第一个时间戳创建签名之后发生了变化。

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方法可能是 1 行：

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