Failed with error: Out of Range (8) read datastream of length 9 over by 1

麒麟测试网部署测试合约时出现一下错误

suroudeMacBook-Pro:contracts surou$ cleos -u http://api.kylin.eosbeijing.one:8880  get table cryptokylinq cryptokylinq results
2018-10-10T14:09:41.215 thread-0   main.cpp:3143                 main                 ] Failed with error: Out of Range (8)
read datastream of length 9 over by 1

开始演示步骤

开始部署合约中表的结构为

//@abi table results i64
    struct approval_info{
        account_name name;
        uint8_t iresult;
        uint64_t primary_key()const { return name; }
        EOSLIB_SERIALIZE(approval_info, (name)(iresult))
    };

    typedef eosio::multi_index<N(results),approval_info> result_table;

然后直接修改了 iresult 为 std::string

//@abi table results i64
    struct approval_info{
        account_name name;
        std::string iresult;
        uint64_t primary_key()const { return name; }
        EOSLIB_SERIALIZE(approval_info, (name)(iresult))
    };

    typedef eosio::multi_index<N(results),approval_info> result_table;

由于前面合约已部署，就像数据库中表字段的类型已经建好了，下次再部署时，导致表错乱，所以改个表名或者重新部署个账号测试把。等后面发现好的办法再跟帖
