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“签名”

如果有人有向Binance签署休息请求的经验，那么朝正确的方向指出我要去哪里的错误将是值得的。

错误{“代码”：-1022，“信息”：“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

好像您要两次调用get_time一样，这可能是您的问题，因为signed request documentation指示签名应包含所有查询参数和连接的请求正文。当您第二次调用get_time时，在您使用第一个时间戳创建签名后，时间戳已更改。

试试看

  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

请注意，您的get_time方法可能是1行：

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