chaincode的API之stub.GetTxTimestam

stub.GetTxTimestamp()是获得创建交易时的时间戳

    t1, _ := stub.GetTxTimestamp()

    time1 := time.Unix(t1.Seconds, int64(t1.Nanos)).String()

    logger.Infof("===========time1======time1=========%s", time1)

stub.GetCreator()是客户端的证书

creatorByte, _ := stub.GetCreator()

注意 返回类型是[]byte类型的
可以根据证书解析出name

creatorByte, _ := stub.GetCreator()
    certStart := bytes.IndexAny(creatorByte, "-----BEGIN")
    if certStart == -1 {
        fmt.Errorf("No certificate found")
    }
    certText := creatorByte[certStart:]
    bl, _ := pem.Decode(certText)
    if bl == nil {
        fmt.Errorf("Could not decode the PEM structure")
    }

    cert, err := x509.ParseCertificate(bl.Bytes)
    if err != nil {
        fmt.Errorf("ParseCertificate failed")
    }
    uname := cert.Subject.CommonName
    fmt.Println("Name:" + uname)
    logger.Infof("===========Name======Name=========%s", uname)
