Ethereum: Binance {code: -1022, msg: ‘Signature for this request is not valid.’}
I can provide you with an article explaining the problem and its solution. However, please note that I will assume basic knowledge of Next.js, SSR (Server-Side Rendering), and the Binance API.
Ethereum Binance API Signing Issue in Next.js with Simple JavaScript Upload
As a developer building a blockchain application using Next.js, you may have encountered issues when integrating the Binance API. A common issue is receiving an error message stating that your request signature is invalid. In this article, we will dive deeper into the causes of this issue and provide steps to fix it.
Issue
When making API requests to Binance using JavaScript Fetch or a similar library, you must include the API key as part of the URL query string. However, the Binance API expects the request body to include a signature (aka HMAC-SHA-256) instead of a query string.
The code snippet provided in the article shows how the API key is passed in the query string:
`javascript
var buyKeys = {
"APIkey": "my API key",
//...
}
When you try to make an API request using JavaScript Fetch with this data, you will receive an error message:
json{
"code": -1022,
"msg": "The signature for this request is invalid."
}
Solution
To resolve this issue, you need to update your API key data to include a signature instead of a query string. The correct way to pass the signature is to use the "Authorization" header in the request body.
Here is an updated example of how to create an API request with the correct signature:
javascript
import {ethers} from 'ethers';
// Replace with your API key and other credentials
const apikey = 'my API key';
const secretKey = 'your secret key';
const contractAddress = '0x...'; // your Binance contract address
async function getOrders() {
const account = await ethers.getSigner();
const order = await account.order({
symbol: "BTCUSDT",
side: "buy",
type: 'limit',
amount: 1,
timeInArrows: '3d'
});
// Include the signature in the request body
const signature = await ethers.ethers.signMessageDigest(
order.rawData.rawTxHash,
account.privateKey,
{ encoding: 'base64'}
);
return {
signature,
contract address,
api key
};
}
export default getOrders;
“
In this example, we use the “signMessageDigest” function to generate a signature for an order request. We include “signature”, “contract address”, and “apikey” in the request body.
Next Steps
Now that you’ve solved the signing problem, make sure you make API requests in the correct format. Also consider implementing error handling and logging mechanisms to better manage any errors that may occur during your application development process.
Also, if you have any additional issues or questions, feel free to ask for help. I hope this article helps you solve the signing problem in your Next.js applications using the Binance API!
