1，建立交易

API接口构建事务，代码api/transact.go#L120

以标准非BTM资产的交易为例，ID由F组成的BTM资产在此交易中仅作为气体。此交易意味着将99个指定资产花费到指定地址，其输入请求的已构建交易的json为如下：

{
  "base_transaction": null,
  "actions": [
    {
      "account_id": "0ER7MEFGG0A02",
      "amount": 20000000,
      "asset_id": "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
      "type": "spend_account"
    },
    {
      "account_id": "0ER7MEFGG0A02",
      "amount": 99,
      "asset_id": "42275aacbeda1522cd41580f875c3c452daf5174b17ba062bf0ab71a568c123f",
      "type": "spend_account"
    },
    {
      "amount": 99,
      "asset_id": "42275aacbeda1522cd41580f875c3c452daf5174b17ba062bf0ab71a568c123f",
      "address": "sm1qxe4jwhkekgnxkezu7xutu5gqnnpmyc8ppq98me",
      "type": "control_address"
    }
  ],
  "ttl": 0,
  "time_range": 0
}

相应的响应对象的源代码如下：

// BuildRequest is main struct when building transactions
type BuildRequest struct {
    Tx        *types.TxData            `json:"base_transaction"`
    Actions   []map[string]interface{} `json:"actions"`
    TTL       json.Duration            `json:"ttl"`
    TimeRange uint64                   `json:"time_range"`
}

结构字段： -Tx TxData个交易，保留字段，为空 -TTL个已构建事务的生存期（ms），这意味着已缓存的utxo不能在该时间段内用于另一个构建事务，除非剩下的utxo足以建立一个新事务，否则会提示错误。 ttl为0，默认值为600s（5分钟） -TimeRange时间戳表示该事务将不在此blockheight（时间戳）之后上链。为避免由于传输延迟而在转移事务时等待太长时间，如果未将其打包在指定的TimeRange中，则该事务将过期。 -Actions actions交易结构，所有交易均由动作组成，map的类型interface{}确保动作类型的可扩展性。动作必须包含类型字段以区分action主要包含input和output之间，其详细介绍：   -input action类型：       -发行发行资产       -在帐户模式下，exped_account花费utxo       -支出_支出_未支出_支出直接花费指定的utxo   -output action类型：       -以地址模式接收control_address       -控制程序以（程序）合同方式接收       -退休退休资产

注意： -一个事务必须包含一个输入和一个输出或t在构建输入和输出时，输入a的资产总和必须等于输出，否则事务将显示错误消息，即输入和输出的不平衡。 -气体：所有投入的BTM资产减少为所有产出的资产 -交易中的资产金额全部以neu为单位，1 BTM = 1000 mBTM = 100,000,000neu

建立交易时的

action类型：

问题

issueAction结构源代码：

type issueAction struct {
    assets *Registry
    bc.AssetAmount
}

type AssetAmount struct {
    AssetId *AssetID `protobuf:"bytes,1,opt,name=asset_id,json=assetId" json:"asset_id,omitempty"`
    Amount  uint64   `protobuf:"varint,2,opt,name=amount" json:"amount,omitempty"`
}

建设领域： -assets资产管理，用户无需设置参数 -AssetAmount ssetID和相应的资产金额，需要通过AssetID创建create-asset，不能使用BTM的资产ID

json的{​​{1}}格式：

估算气

估算费用界面quorum用于keys费用估算，估算结果必须添加到quorum结果中，然后签名并提交交易。主要过程如下： DataWitness

预算程序费的输入请求json格式如下：

AllowAdditional

相应的响应对象的源代码如下：

true

您可以在build-transaction的结果描述中看到包括program在内的相关字段

成功返回json结果后，调用false接口如下：

estimate ws-transaction - gas

相应的响应对象的源代码如下：

build -transaction

结构字段解释如下： -build -transaction估算气体（neu），您可以通过输入操作将值添加到build-transaction的BTM资产中 - build - estimate - build - sign - submit 用于存储交易的气体

相应请求对象的源代码如下：： 

type SignRequest struct {    //function pseudohsmSignTemplates request
    Password string             `json:"password"`
    Txs      txbuilder.Template `json:"transaction"`
}

结构字段解释如下： -Password签名密码，根据密码分析节点服务器上用户的私钥，然后使用私钥签名进行交易 -Txs交易模板，构建交易的返回结果，其结构类型为txbuilder.Template，您可以在构建交易的说明中看到相关字段

sign-transaction成功请求后返回的json结果如下：

    Tx           *txbuilder.Template `json:"transaction"`
    SignComplete bool                `json:"sign_complete"`
}

结构字段说明如下： -txbuilder. Template签名后的交易模板Tx，如果签名成功的signatures从null更改为签名的值，并且raw_transaction的长度会更长，因为{{1 }}部分添加以验证签名信息的参数 去完成 - -BC. Tx标记签名是否完成，对于SignComplete，签名完成，还是对于true，签名，对于单个签名，通常是错误的签名密码，而对于其他签名则需要其他签名-签名。如果签名失败，请使用正确的密码再次签名，无需再次false

3，提交交易

APIinterface提交事务，代码api/transact.go#L135

提交交易的输入请求采用json格式，如下所示：

build-transaction
