contract_maintainContract

升级合约、冻结合约、解冻合约。 只有合约的部署者才拥有升级合约、冻结合约、解冻合约的权限。

Parameters

1. <Object>

• from: <string> - 20字节的十六进制字符串，交易发送方的地址。
• to: <string> - 20字节的十六进制字符串，合约地址。
• nonce: <number> - 16位随机数，该值必须为十进制整数。
• extra: <string> -[可选] 交易的额外信息。
• timestamp: <number> - 交易发生时间戳（单位ns）。
• payload: <string> - [可选] 编译后的新合约字节码。升级合约才需要这个字段。
• signature: <string> - 交易签名。
• type: <string> - 指定合约执行引擎，默认为“evm”。如果合约代码由java语言编写，则需要设置该值为“jvm”。
• opcode: 值为1表示升级合约，值为2表示冻结合约、值为3表示解冻合约。

注解

说明：to合约地址需要在部署完合约以后，调用 tx_getTransactionReceipt 方法来获取。

Returns

1. <string> - 32字节的十六进制字符串，交易的哈希值。
