in_pack中是否传入trans_id

从in_pack读取买家属性，放入info.buyeruser_idlogin_nametrue_namecurrency赋默认值info.buyer.sub_account_type = SUB_ACCOUNT_TYPE_DEFAULT

is_reentry是否为重入

校验以下信息必须一致trans_typepayment_modesellersp_idshare_profit_flag必须为未分润

TRANS_CANNOT_MODIFY

seller是customer或者merchantuser_id分布规则

是否传入平台商户if (!has_up_merchant)

校验金额info.validate()total_good_amount = unit_price_amount * unit_count + transport_amount + adjust_price_amount + adjust_transport_amount;total_payment_amount = cash_amount + coupon_amount + pay_solution_amount + mkt_solution_amount + coupon_amount_new;total_good_amount必须等于total_payment_amount

如果传入和redis中的trans_mode一致即都是非纯网关

!in_redis如redis中没有

info.seller.sub_account_type = SUB_ACCOUNT_TYPE_DEFAULT(1)卖家使用已结算账户

buyer_fee_account != info.seller收益账户不与卖家相同

info.seller.sub_account_type = SUB_ACCOUNT_TYPE_UNSETTLED(3)卖家使用待结算账户

if (0 != info.fee_amount)只有fee_amount不为0时才需要fee_user_id

fee_account收益账户必须是C账户

if (0 info.coupon_strategy_id)

从in_pack读入端信息，放入infoclient_source_flag_create并设置has_client_source_flag_create

如果multiple_in则pay_trans_solution要一致如果multiple_out则share_profic_solution要一致

没看明白干啥呢？为啥？

手续费不能大于交易总现金金额if (info.fee_amount info.get_total_cash_amount())（(cash_amount + pay_solution_amount + mkt_solution_amount - _mkt_total_no_settlement_amount)）

从in_pack读入上层商户信息，放入infoup_merchant_info设置has_up_merchant

从in_pack读入卖家信息，放入info.sellersp_iduser_idlogin_nametrue_name设置seller.currency=buyer.currency

buyer是customer或者merchantuser_id分布规则

info.settlement_type!=realtime为异步结算

数据库有的话用数据库的，否则调用billNo新生成一个trans_id_in_redis = is_used ? info.trans_id : trans_id_client_.info_bill_no(

is_full_match

handle_cannot_modify_scenario（is_reentry=false）

检查平台商户传入是否正确

计算并行支付类型，放入info.parallel_type1）如传入有付款方案，10102）如传入有分润或分账方案，01013）啥都没有，0000

info.channel_id = trans_settlement_info::CHANNEL_ID_DEFAULT(1)

将trans和写入out_pack如果不是委托分账则将trans_solution写入out_pack

从in_pack读入其它MISC信息，放入infoext_time、deadline_time放入info.extrasource_ip、user_mac、comments

从in_pack读取交易属性，放入infotrans_id_exttrans_typetrans_tagcan_modifytrans_mode从模板获取payment_mode，放入info

委托分账必须实时分润is_entrust_billing_solution && info.share_profit_type != SHARE_PROFIT_TYPE_REALTIME

卖家买家user_id不同

即在redis里又在库里，且判断trans_id是否一致if (is_used && in_redis && trans_id_in_redis != info.trans_id)

校验一下信息必须一致trans_modebuyer.login_name/user_id/sub_account_type/currency

if (has_share_profit_solution && is_entrust_billing_solution)|| has_share_profit_solution && info.share_billing_type != trans_info::SHARE_TRANS_TYPE_NORMAL如果传入有分润方案，则不能为委托分账或分普通类型分账

从in_pack读入商品信息，放入infogoods_namegoods_urlgoods_typegoods_channelgoods_channel_sp_id

buyer_fee_account必须存在（查DB）

如果是预下单if (cm == pre_mode_to_create_trans) {

传入的trans_mode必须是非纯网关

switch (info.can_modify)要么传入，要么默认cannot

info.share_profit_type = info.SHARE_PROFIT_TYPE_REALTIME如果有分润方案默认使用实时分润

has_share_profit_solution

获取redis重入keyredis_key = cmd_trans_id_ext_logid;

校验以下信息必须一致商品信息：goods.goods_name/url/type结算信息：settlement.fee_amount/fee_account/channel_id/settlement_type买家信息：buyer_fee_amount/buyer_fee_account

给trans_id赋值如果redis里面有，直接用如果redis里没有库里有。用库里的如果redis和库里都没有，生成info.trans_id = trans_id_in_redis;

if ((has_share_profit_solution || is_entrust_billing_solution)&& (info.SETTLEMENT_TYPE_REALTIME != info.settlement_type))前只有实时结算才支持分润或者分账

如果是普通分账

check_up_merchant_info

赋值给pay_solution_amountinfo.pay_solution_amount = solution_info.pay_trans_solution().get_total_amount();

buyer_fee_account != info.buer收益账户不与买家相同

为啥不是委托分账才写

从in_pack读入info.fee_account.user_idinfo.fee_account.sub_account_type = SUB_ACCOUNT_TYPE_DEFAULT(1)info.fee_account.currency = info.buyer.currency

has_read_channel_id？

buyer_fee_account收益账户必须是C账户

从In_pack读取付款以及分润方案信息，放入solution_infopay_trans_solutionshare_profit_solution设置has_pay_trans_solution、has_share_profit_solution

依据info.trans_id_ext从redis中查询trans_id，放入trans_id_in_redis，并设置in_redis

if (0 != info.coupon_amount)目前不支持coupon_amount，所以coupon_amount一定要为0

service_exception

为啥非重入就异常

从in_pack读取create_mode，放入cm

抛异常PAY_ERR_TRANS_ALREADY_CREATED

永远都不允许改的交易单信息

fee_account必须存在（查DB）

in_redis如果缓存里面有

分润总金额不能大于分润前支付给卖家的金额if (solution_info.share_profit_solution().get_total_amount() (info.get_total_cash_amount() - info.fee_amount))

有can_modify为CAN_MODIFY_ALL可以改的信息

has_pay_trans_solution如果传入有付款方案

去DB中查询是info.trans_id_ext去否存在如存在，将trans_id放入info.trans_id设置is_used

如果传入付款方案分润方案，则赋值给本地变量，if (has_pay_trans_solution/has_share_profit_solution) {trans_solution.pay_trans_solution/share_profit_solution = solution_info.pay_trans_solution/share_profit_solution;

从in_pack读入info.buyer_fee_account.user_idinfo.buyer_fee_account.sub_account_type = SUB_ACCOUNT_TYPE_DEFAULT(1)info.buyer_fee_account.currency = info.buyer.currency

初始化一些值bool is_modified = false;info.state = info.TRANS_STATE_CREATED;info.share_profit_flag = info.SHARE_PROFIT_FLAG_UNDO;
