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.
