Here is an article about Solana: Decoding data from the Accountsubscribe WebSocket method using a rust:
Data Decoding with ACCOUNTSUBSCRIPTION WebSocket in Solana with rust
The WSS “AccountsubsCrict” method (WebSockets subscribers) is a powerful tool to download data relating to Solana Blockchain Subscriber. If used properly, it can give a valuable idea of the participation and transactions of your Vault property. However, the decoding of the coded JSON of the beneficial load of Base64 obtained from the server may be a challenge.
In this article, we will study how to decode the data sent by the accountsubscrict using a rust, focusing on the specific requirements of portfolio addresses based on the portfolio, such as the “bases” and “quoted” assets.
Prerequisites
Before you dive into the code you must have:
Solana-Websocket 'installed in your Project RustExample Code
Below is an example of how to get data fromAccountsubsCrictusing the" Solana-Websocket "box:
Rust
Use Solana_sdk :: {Accountinfo, PubKey};
Use Solana_websoCket :: {ApspubletionResponse, subscription};
#[Tokyo :: Basic]
Async fn main () {{)
// initialize your salt node
Let (context, accounts) = tokyo :: Mrrijwn (Solana_node :: Init ());
// subscribe to the events of Accountsubscribe
Let the subscription_options = subscriptions :: new (
Contextpubkey,
PubKey :: New ("Your Acknowledgments"),
);
Let the subscription_response = tokio :: Run (subscription_options);
// analyzes the answer as json
Let Json: Serde_json :: Value = Serde_json :: from_str (& subscription_response) .unwrap ();
// cycles through each account and print his details
for (Account_id, information) in json ["accounts"]. Iter () {{
Println! ("Account ID: {}", Account_id);
Println! ("Pubkey: {}", info.pubkey.to_string ());
Println! ("Owner: {}", info.owner.value ());
Println! ("Tip: {}", info.type_.value ());
// ...
Iche
Iche
// Determine subscription options
#[Denive (default)]
Struct subscribers {
PubKey: Pubkey,
Iche
In this example, we initialize the junction of the solana usingTokyo :: Spawn, and then subscribe to the events of Accountsubscribe. We analyze the answer as Json and the bike through each account by printing his details.
Decoding 64-coded databases
After receiving Json's response fromAccountsubscribe,” Base64 coded it. To decoded this information, we can use the following steps:
Serde_json :: From_str.Here’s an example of how to deal with these steps:
`Rust
Use Serde :: {desseralize, serialize};
Use base64;
#[Denive (default)]
Struct adBoncriptionresponse {
Accounts: already
Iche
Imple Serde_json :: Subscribe Card for Reply {
Fn Get (& Self, Key: & Str) -> Option <& Serde_json :: Value> {
Match [Key] {{
Some (value) => value,
None => no,
Iche
Iche
fn as_bytes (& self) -> option
match self.as_ref () {{
Some (map) => map.get ("accounts"). Map (| Value | Base64 :: Decoding (Value) .unwrap ()),
_ => No,
Iche
Iche
Iche
In this example, we define the subscription structure to an answer that implement 'Serde_json :: Map. We also apply the necessary methods to process the decoding of binary data at JSON.
Finally, when we analyze the answer such as JSON and call As_bytes, we use ‘Base64 :: Decode` for decipher any binary data present at the JSON web site. If binary data is not found, the method returns “no”.
