How to realize EOS push operation
Most people do not understand the knowledge points of this article "how to achieve EOS push operation", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to achieve EOS push operation" article.
Push operation
According to the contract ABI, the message should be the contract.
For example, the ABI of a currency contract is constructed as follows.
$cleos get code-a currency.abi currencycode hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975saving abi to currency.abi$ cat currency.abi {"types": [{"newTypeName": "AccountName", "type": "Name"}], "structs": [{"name": "transfer", "base": "", "fields": {"from": "AccountName", "to": "AccountName" "amount": "UInt64"}, {"name": "account", "base": "", "fields": {"account": "Name", "balance": "UInt64"}], "actions": [{"action": "transfer", "type": "transfer"}] "tables": [{"table": "account", "indextype": "i64", "keynames": ["account"], "keytype": [], "type": "account"}]}
From the abi above, we can see that the currency contract accepts an operation called transfer, which accepts messages with from,to and amount fields.
