  什麼是社交新零售


  社交新零售,以社交賦能新零售模式,提升零售效率為目的的企業升級解決方案。社交新零售,是在消費升級時代,企業構建以消費者為中心的先進模式,從而獲得競爭優勢和效率提升。


  Public bus system:a simple example is to show that all the people in the country are in the same area,with two points on the first floor,four points on the second floor,eight points on the third floor,and rows horizontally.After the first floor is occupied,the next floor is arranged again,and the second floor is copied,that is to say,the length is increased.


  def buy(self,consumed_token_amount,consumed_token_address=ETH_ADDRESS,slippage=0.01,timeout=900,speed=1):


  gas_price=int(self.web3.eth.gasPrice*speed)


  consumed_token_address=Web3.toChecksumAddress(consumed_token_address)


  received_amount=self.received_amount_by_swap(consumed_token_amount,consumed_token_address)


  min_out=int(received_amount*(1-slippage))


  if consumed_token_address==self.ETH_ADDRESS:


  func=self.router.functions.swapExactETHForTokens(min_out,[consumed_token_address,self.address],


  self.wallet_address,int(time.time()+timeout))


  params=self.create_transaction_params(value=consumed_token_amount,gas_price=gas_price)


  else:詳細及方案:MrsFu123


  if not self.is_approved(consumed_token_address,consumed_token_amount):


  self.approve(consumed_token_address,gas_price=gas_price,timeout=timeout)


  func=self.router.functions.swapExactTokensForTokens(consumed_token_amount,min_out,


  [consumed_token_address,self.address],


  self.wallet_address,int(time.time()+timeout))


  params=self.create_transaction_params(gas_price=gas_price)


  return self.send_transaction(func,params)


  consumed_token_address:設定所支付的代幣的erc20合約地址。


  consumed_token_amount:設定所支付的代幣數量。


  slippage:設定所能容忍的滑點,預設為百分之一。


  timeout:設定該筆交易的超時時間。


  speed:設定該筆交易的區塊確認速度,透過平均的gas_price乘以speed設定該筆交易的gas_price,所以speed的值越大,gas_price也越大,使得該筆交易的確認速度也越快。
