说明
-
以下api说明中{xxx}表示变量/参数
-
所有请求和返回均为json
请求格式
{
"jsonrpc": "2.0",
"method": "{method}",
"params": {
"type": 1,
"chaincodeID":{
"name":"{chaincodeId}"
},
"ctorMsg": {
"function":"{function}",
"args":["{参数1}","{参数2}","{参数3}"...]
}
},
"id":{id}
}
{method} query/invoke
{chaincodeId} 测试前提供
{function} 实际操作，见具体API
{args} 调用参数，见具体API
返回格式
{
"jsonrpc": "2.0",
"result": {
"status": "{status}",
"message": "{body}"
},
"id":{id}
}
- 所有invoke方法调用都是异步提交方式，返回结果只有事务TXID。
status ok不代表执行成功，执行结果无法直接查看，只能通过查看world state状态查看调用结果
{
"jsonrpc": "2.0",
"result": {
"status": "OK",
"message": "{TXID}"
},
"id":{id}
}
{id}:数字,序号,暂无意义,下同
-
目前fabric无法查询到返回结果，demo阶段将执行结果放入world state供查询。

1.交易所
字段
- marketId 交易所id,demo阶段只需要创建一个票交所，所有交易都在一个票交所交易
- address 地址
- name 名称
- priKey 私钥。签名使用，demo不做数字签名，只简单比较私钥。值为pri-{marketId}
- pubKey 公钥。值为pub-{marketId}
1.1创建交易所

"id":{id}
}
response
{
"jsonrpc": "2.0",
"result": {
