Printing the response from a binning command
In this article, we will deepen the way of printing the response from a order on the binance platform using the customer.order_limit_buy (). This is useful for troubleshooting and troubleshooting.
preliminary conditions
- Make sure you have an Ethereum node that works with a library of compatible customers (eg, Ethers.js or Web3.JS).
- Make sure you have installed the necessary libraries through NPM or threads:
`Bash
NPM Install Eterus
or
Bash
The thread adds ethers
Printing response from a command
In order to print the answer from a order, we must first create a new order and then take over our answer. Here is an example of implementation:
Javascript
const web3 = requires (‘web3’);
Const Ethers = requires (‘ethers’);
// replace with the credentials of the Ethereum node (for example, «
Const Etnodeurl = ‘
// create a new web3 instance3
Const web3 = New Web3 (New Ethers.Providers.JsonrpCProvider (Ethnodeurl));
// set here the credentials of the Ethereum node (replace -you with your real credentials)
Const Nodeurl = process.env.ethern_node_url || ‘
// Define command parameters
Consty symbol = ‘adabus’;
Const buyquantity = 100; // adjust this amount according to your needs.
Price Const = 20000; // replace with a valid Ethereum price
// create an instance of the customer
CON CUSTOM = New Ethers.Contract (0x … your contract address … ‘, Ethers contractFactory);
// place your order
command = wait for client.orderlimitbuy (
symbol,
purchase,
price,
« ACK »
);
// recover the response from order
consist response = wait for client.orderresponse (order);
console.log (answer);
`
In this example, we create a newWeb3 ‘instance using the credentials of the Ethereum node. Then we define the command parameters (symbol, quantity and price). Finally, we place the command using the commandlimitBuy () `and we recover its answer using theCommander ()method.
Printing the answer
The answer in the order is an object that contains various properties such as:
- Status: the status of the order (for example, » waiting « , » completed « or » canceled « ).
msg: a message that describes the result of the operation.
Result: the result of the operation (for example, the quantity completed).
To print this answer, you can use the following code:
Javascript
if (answer.status === ‘filled’) {
console.log (command $ {command.id} was successfully completed for $ {buyquantity} adabus to $ {price} .);
}
otherwise if (answer.status === ‘canceled’) {
console.log (command $ {command.id} has been canceled.);
}
something else {
console.log (error: $ {answer.msg});
}
This will print the response from order to console, allowing you to troubleshoot and troubleshoot your Ethereum transactions.
Don't forget to replace… your contract address …` with the real address of the Ethereum contract that generated the order.
