[English|中文]
Ontology Signature Server - sigsvr is a rpc server for signing transactions. The signature server is bound to the 127.0.0.1 address and only supports signature requests sent by the local machine.
--loglevel The loglevel parameter is used to set the log level for the sigsvr output. Sigsvr supports 7 different log levels - 0:Debug 1:Info 2:Warn 3:Error 4:Fatal 5:Trace 6:MaxLevel. The log level is from low to high, and the output log volume is from high to low. The default value is 1, which means that only output logs at the info level or higher level.
--wallet, -w The wallet parameter specifies the wallet file path when sigsvr starts. The default value is "./wallet.dat".
--account, -a The account parameter specifies the account address when sigsvr starts. If the account is null, it uses the wallet default account.
--cliport The port number to which the signature server is bound. The default value is 20000.
--abi abi parameter specifies the abi file path when sigsvr starts. The default value is "./abi".
./sigsvr
The signature service currently supports signature for data, single signature and multi-signatures for raw transactions, constructing ONT/ONG transfer transactions and signing, constructing transactions that Native contracts can invoke and signing, and constructing transactions that NeoVM contracts can invoke and signing, and so on.
The signature service is a json rpc server and adopts the POST method. The requested service path is:
http://localhost:20000/cli

The Native contract invocation transaction is constructed and signed according to the ABI.
Note: When sigsvr starts, it will default seek the native contract abi under "./abi" in the current directory. If there is no abi for this contract in the naitve directory, then it will return a 1007 error. Can use --abi parameter to change the abi seeking path.
Method Name: signativeinvoketx
Request parameters:
{
"gas_price":XXX, //gasprice
"gas_limit":XXX, //gaslimit
"address":"XXX", //The address that invokes native contract

The NeoVM parameter contract supports array, bytearray, string, int, and bool types. When constructing parameters, it is necessary to provide parameter types and parameter values. The parameter values use string types. Array is an array of objects and supports all types and quantities of NeoVM supported parameters.
