|
Usage: "invoke deployed contract on the blockchain (test mode)",
|
|
UsageText: "neo-go contract testinvokefunction -r endpoint scripthash [method] [arguments...] [--] [signers...]",
|
|
Description: `Executes given (as a script hash) deployed script with the given method,
|
|
arguments and signers (sender is not included by default). If no method is given
|
|
"" is passed to the script, if no arguments are given, an empty array is
|
|
passed, if no signers are given no array is passed. If signers are specified,
|
|
the first one of them is treated as a sender. All of the given arguments are
|
|
encapsulated into array before invoking the script. The script thus should
|
|
follow the regular convention of smart contract arguments (method string and
|
|
an array of other arguments).
|
|
|
|
Arguments always do have regular Neo smart contract parameter types, either
|
|
specified explicitly or being inferred from the value. To specify the type
|
|
manually use "type:value" syntax where the type is one of the following:
|
|
'signature', 'bool', 'int', 'hash160', 'hash256', 'bytes', 'key' or 'string'.
|
|
Array types are also supported: use special space-separated '[' and ']'
|
|
symbols around array values to denote array bounds. Nested arrays are also
|
|
supported.
|
|
|
|
Given values are type-checked against given types with the following
|
|
restrictions applied:
|
|
* 'signature' type values should be hex-encoded and have a (decoded)
|
|
length of 64 bytes.
|
|
* 'bool' type values are 'true' and 'false'.
|
|
* 'int' values are decimal integers that can be successfully converted
|
|
from the string.
|
|
* 'hash160' values are Neo addresses and hex-encoded 20-bytes long (after
|
|
decoding) strings.
|
|
* 'hash256' type values should be hex-encoded and have a (decoded)
|
|
length of 32 bytes.
|
|
* 'bytes' type values are any hex-encoded things.
|
|
* 'key' type values are hex-encoded marshalled public keys.
|
|
* 'string' type values are any valid UTF-8 strings. In the value's part of
|
|
the string the colon looses it's special meaning as a separator between
|
|
type and value and is taken literally.
|
|
|
|
If no type is explicitly specified, it is inferred from the value using the
|
|
following logic:
|
|
- anything that can be interpreted as a decimal integer gets
|
|
an 'int' type
|
|
- 'true' and 'false' strings get 'bool' type
|
|
- valid Neo addresses and 20 bytes long hex-encoded strings get 'hash160'
|
|
type
|
|
- valid hex-encoded public keys get 'key' type
|
|
- 32 bytes long hex-encoded values get 'hash256' type
|
|
- 64 bytes long hex-encoded values get 'signature' type
|
|
- any other valid hex-encoded values get 'bytes' type
|
|
- anything else is a 'string'
|
|
|
|
Backslash character is used as an escape character and allows to use colon in
|
|
an implicitly typed string. For any other characters it has no special
|
|
meaning, to get a literal backslash in the string use the '\\' sequence.
|
|
|
|
Examples:
|
|
* 'int:42' is an integer with a value of 42
|
|
* '42' is an integer with a value of 42
|
|
* 'bad' is a string with a value of 'bad'
|
|
* 'dead' is a byte array with a value of 'dead'
|
|
* 'string:dead' is a string with a value of 'dead'
|
|
* 'AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y' is a hash160 with a value
|
|
of '23ba2703c53263e8d6e522dc32203339dcd8eee9'
|
|
* '\4\2' is an integer with a value of 42
|
|
* '\\4\2' is a string with a value of '\42'
|
|
* 'string:string' is a string with a value of 'string'
|
|
* 'string\:string' is a string with a value of 'string:string'
|
|
* '03b209fd4f53a7170ea4444e0cb0a6bb6a53c2bd016926989cf85f9b0fba17a70c' is a
|
|
key with a value of '03b209fd4f53a7170ea4444e0cb0a6bb6a53c2bd016926989cf85f9b0fba17a70c'
|
|
* '[ a b c ]' is an array with strings values 'a', 'b' and 'c'
|
|
* '[ a b [ c d ] e ]' is an array with 4 values: string 'a', string 'b',
|
|
array of two strings 'c' and 'd', string 'e'
|
|
* '[ ]' is an empty array
|
|
|
|
Signers represent a set of Uint160 hashes with witness scopes and are used
|
|
to verify hashes in System.Runtime.CheckWitness syscall. First signer is treated
|
|
as a sender. To specify signers use signer[:scope] syntax where
|
|
* 'signer' is hex-encoded 160 bit (20 byte) LE value of signer's address,
|
|
which could have '0x' prefix.
|
|
* 'scope' is a comma-separated set of cosigner's scopes, which could be:
|
|
- 'None' - default witness scope which may be used for the sender
|
|
to only pay fee for the transaction.
|
|
- 'Global' - allows this witness in all contexts. This cannot be combined
|
|
with other flags.
|
|
- 'CalledByEntry' - means that this condition must hold: EntryScriptHash
|
|
== CallingScriptHash. The witness/permission/signature
|
|
given on first invocation will automatically expire if
|
|
entering deeper internal invokes. This can be default
|
|
safe choice for native NEO/GAS.
|
|
- 'CustomContracts' - define valid custom contract hashes for witness check.
|
|
- 'CustomGroups' - define custom pubkey for group members.
|
|
|
|
If no scopes were specified, 'Global' used as default. If no signers were
|
|
specified, no array is passed. Note that scopes are properly handled by
|
|
neo-go RPC server only. C# implementation does not support scopes capability.
|
|
|
|
Examples:
|
|
* '0000000009070e030d0f0e020d0c06050e030c02'
|
|
* '0x0000000009070e030d0f0e020d0c06050e030c02'
|
|
* '0x0000000009070e030d0f0e020d0c06050e030c02:Global'
|
|
* '0000000009070e030d0f0e020d0c06050e030c02:CalledByEntry,CustomGroups'
