演示合约代码
合约中Table表结构
struct [[eosio::table, eosio::contract("bcskillsurou")]] extract_token {
uint64_t id;
eosio::checksum256 transaction_id; // 交易单id
auto primary_key() const { return id; }
eosio::checksum256 second_key() const { return transaction_id; } // 已hash作为二级索引
EOSLIB_SERIALIZE(extract_token, (id)(transaction_id))
};
typedef eosio::multi_index<"xxxxtb"_n, extract_token, eosio::indexed_by<"bysubkey"_n, eosio::const_mem_fun<extract_token, eosio::checksum256, &extract_token::second_key>>> xxxx_table;
合约中查询代码
ACTION findtrxid(eosio::checksum256 trx_id){
....
xxx_table xxxtb(_self, _self.value);
auto sub_extract_index = xxxtb.get_index<"bysubkey"_n>();
auto itr_xxx = sub_xxx_index.find(trx_id);
eosio_assert(itr_extract != sub_xxx_index.end(), "Record not found");
....
}
使用Cleos 复现问题
cleos push action 合约账户 findtrxid '{"trx_id":0bb0e5901c3b627484c6a1a473ba8e3e3a3ffb4b96f849e08afb2d1e2671b88d}' -p 合约账户
返回
Error 3050003: eosio_assert_message assertion failure
Error Details:
assertion failure with message: {"code":102,"msg":"Record not found 563"}
经过测试发现是因为eosio::checksum256 trx_id
传参最终打包不是已字符串打包导致,交易id上传后被识别成了
1116029241376226714100000000000000000000000000000000000000000000
解决方案
修改eosio::checksum256 trx_id
为字符串即可
cleos push action 合约账户 findtrxid '{"trx_id":"0bb0e5901c3b627484c6a1a473ba8e3e3a3ffb4b96f849e08afb2d1e2671b88d"}' -p 合约账户
对于其他语言封装,处理eosio::checksum256 trx_id
统一字符串打包即可
备注
特殊hash复现
