成功搭建后加入区块链部分，其中遇到的问题：

1.区块链相关代码：

from django.shortcuts import render, redirect
from django.contrib import messages
from app01 import models
from app01.utils.pagination import Pagination
from app01.views.sdk.client.bcosclient import BcosClient
from app01.views.sdk.client.bcoserror import BcosException, BcosError
from app01.views.sdk.client.datatype_parser import DatatypeParser
from app01.views.sdk.eth_utils import to_checksum_address
# 上链开始
#materialname = request.POST.get('materialname')  # 获取原料名称
uid=request.session.get("info")  # 获取厂家ID

# 从文件加载abi定义
abi_file = "D:\\python\\djangoProject6\\app01\\views\\sdk\\contracts\\SimpleInfo.abi"
data_parser = DatatypeParser()
data_parser.load_abi_file(abi_file)
contract_abi = data_parser.contract_abi
try:
    client = BcosClient()  # 实例化一个client对象
    print(client.getinfo())
    # 部署合约
    print("\n>>Deploy:----------------------------------------------------------")
    with open("D:\\python\\djangoProject6\\app01\\views\\sdk\\contracts\\SimpleInfo.bin",
              'rb') as load_f:
        contract_bin = load_f.read()
        load_f.close()
    result = client.deploy(contract_bin)
    print("deploy", result)

    # 发送交易，调用一个改写数据的接口
    print("\n>>sendRawTransaction:----------------------------------------------------")
    to_address = result['contractAddress']
    args = [number, int(uid),
            to_checksum_address('0x7029c502b4F824d19Bd7921E9cb74Ef92392FB1c')]
    receipt = client.sendRawTransactionGetReceipt(to_address, contract_abi, "set", args)
    print("receipt:", receipt)

    # 调用一下call，获取数据
    print("\n>>Call:------------------------------------------------------------------------")
    res = client.call(to_address, contract_abi, "getname")
    print("call materialname:", res)
    res = client.call(to_address, contract_abi, "getbalance")
    print("call factoryid result:", res)

except BcosException as e:
    print("execute demo_transaction failed ,BcosException for: {}".format(e))
    traceback.print_exc()
except BcosError as e:
    print("execute demo_transaction failed ,BcosError for: {}".format(e))
    traceback.print_exc()
except Exception as e:
    client.finish()

    traceback.print_exc()
client.finish()
# 上链结束

tip：注意路径和要引入的包

2.证书拷贝问题
