1. 电子存证合约
代码样例参看:contractsdk/go/example/eleccert.go
1.1. 电子存证合约简介
电子存证应用主要是通过区块链解决的存证中的信任问题,而存证合约只需做简单的读写操作即可
1.2. 电子存证合约具备的读写操作
- 通过invoke方法,put存证到区块链
- 通过query方法,get存证
1.3. 调用json文件示例
Invoke
./xchain-cli native invoke -a ‘下面json中args字段的内容’ —method save -H localhost:37101 eleccert
{
"module_name": "native", // native or wasm
"contract_name": "eleccert", // contract name
"method_name": "invoke", // invoke or query
"args": {
"owner": "aaa", // user name
"filehash": "存证文件的hash值",
"timestamp": "存证的timestamp"
}
}
Query
./xchain-cli native query -a ‘args内容’ —method query -H localhost:37101 eleccert
{
"module_name": "native", // native or wasm
"contract_name": "eleccert", // contract name
"method_name": "query", // invoke or query
"args": {
"owner": "aaa", // user name
"filehash": "文件hash值"
}
}
// output
{
"filehash": "文件hash值",
"timestamp": "文件存入timestamp"
}
