Ethereum: Nodejs, Binance API : Timestamp for this request is outside of the recvWindow
Ethereum node.js Integration with Binance API: Unlock the “Time Stamp” error
As a developer with Ethereum nodes and Binance API, you are likely to know the importance of syncing data between the two. However, if these ingredients are integrated, there may be problems for various reasons. In this article, we are immersed in the “Timestamp” error, which causes problems for node.js applications, especially when using the Binance API.
The “Recvwindow” release
When you make requests to the Binance API with Node.js, it is essential to ensure that the request time stamp is within “Recvwindow”. ‘Recvwindow’ represents the minimum time (in a millisecond) that the customer has to wait before sending a new request. This concept is essential for treating concomitant requests.
TIMESTAMP Error: Short background
The time stamp error occurs when the current timestamp of the application exceeds “Recvwindow”. This can be done because of various factors, for example:
* Network Delay : A sudden spike of network traffic or pack loss can cause time stamps to shift from synchronous.
* Time Zone Differences
: When dealing with APIs that operate through different time zones, time stamps may occur.
* API Version Changes : New API versions can introduce new requirements or restrictions, such as increased Recvwindow» values.
Troubleshooting the problem
To solve the problem, follow these steps:
1. Observe the network latency
Before immersing in the node.js code, watch the network delay with devices such as "ping", "TCPDump" or special network surveillance software (such as Prometheus, Grafana). This helps to identify possible problems with network connection.
2. Check the differences in time zone
Check that all parts involved in API requests are properly configured to manage the time zone differences. Make sure that:
- Binance API is correctly set to the customer.
- Node.js and other addictions support time zone conversions.
updated node.js code
To solve this problem, you can change the Node.js code as follows:
Javascript
const {client} = need ('cosmia node');
const BNB = new client ();
Bnb.apiurl = '
Async function getmarketdata (symbol) {
Const params = {{
symbol,
Limit: 10, // Set the number of requests as necessary
Timestamp: Date.now () - 1000, // Set the time stamp shift
};
Try {
Const Result = Waiting for BNB.QUERY (orders? symbol = $ {symbol} & limit = 10 & Timestamp = $ {params.timestamp}
);
return result.Body;
} catch (error) {
if (error.responsecode === 2004) {// Connection error
throw a new error (‘connection error’);
}
throw error;
}
}
// Example of use:
GetMarketdata (‘ETH/USDT’)
.Then ((data) => console.log (data))
.catch ((error) => console.error (error));
`
3. Set Recvwindow
As a final solution, you can set “Recvwindow” when you make requests to the Binance API. You can do this by creating a separate feature that controls the time stamp of API calls:
“ Javascript
Const max_recv_window = 60000; // 1 minute
constitimestamps = {};
Async function setrecivevetimeestamp (symbol) {
CONST CURRENTITTIMESPAMP = DATE.NOW ();
if (! buyingimestamps [symbol]) {
Buyerimestamps [symbol] = [];
}
buyingimestamps [symbol] .push (Currenttimestamp);
}
Async function gettimestampforrequest (symbol, maxrerecvwindow = max_rerecv_window) {
Setrecivetimeestamp (symbol);
// Get the latest time stamp
Const Timespestamps = Buyerimestamps [Symbol];
constimestamp = math.max (… time stamp);
IF (latest TimeSamp + MaxreCVWindow
