kandi X-RAY | jsonrpc Summary
JSON-RPC is a Java library implementing a very light weight client/server functionality of JSON-RPC protocol. Server/Client API is designed in such a way that, you don't have to worry about the details of the protocol. Just register the implementation classes in the server side, and create remote proxy objects at the client sides on the fly. The API works well in Android/Google App Engine/Javascript applications.

QUESTION
In the code below I'm making two calls to two different APIs. However, instead of running the calls one after the other I would like to run them concurrently. I understand there may be different ways of doing this and I was wondering if there is a prefered way?

When querying archival node for transactions with EXPERIMENTAL_tx_status
method, some transactions have no receipts
while having receipts_outcome
. How is that possible, and how is that transaction different from others?
If I understand correctly, receipts_outcome
are the results of applying receipts
. According to explorer, this transaction has Convert Transaction To Receipt
part, so there should be some receipts generated.
According to documentation
A Receipt is the only actionable object in the system. When we talk about "processing a transaction" on the NEAR platform, this eventually means "applying receipts" at some point.
A good mental model is to think of a Receipt as a paid message to be executed at the destination (receiver). And a Transaction is an externally issued request to create the Receipt (there is a 1 to 1 relationship).
My query
...ANSWER
Answered 2022-Feb-14 at 13:11TL;DR the receipt is a local receipt
The transaction from your example is a simple AddKey
action where the sender is the receiver (remember this, it's important)
- "Execute" transaction (means to convert the transaction into a Receipt)
- Apply the Receipts
As the result of the conversion of the transaction into a receipt is your transaction_outcome

I'm trying to figure out a way to create a generic Websocket JsonRpc client.
After connecting I'm starting a loop to listen for data coming from the WebSocket API and sending that data to the event as a string. I'd like to return a generic JsonRpcResponse
object instead but not sure how or if it's possible.
Where JsonRpcResponse
has an Id
and Method
fields as defined in the spec and T
is a specific type depending on the data received.
From what I've seen there's no way to use generics here since I'd have to call another event with a non-generic type or object
to pass that data along.

QUESTION
When trying to batch json rpc requests like this:
...ANSWER
Answered 2022-Jan-17 at 08:44You are right, batch JSON RPC requests are not supported by nearcore JSON RPC implementation. Batch JSON RPC requests can become arbitrary heavy. It is preferred to leverage load balancer to get several requests resolved, so just make separate calls instead of batching them.
I wonder what is your use-case, though. Maybe you want to take a look into Indexer Framework
QUESTION
ANSWER
Answered 2022-Jan-09 at 14:47This is caused by a bug in the Hyperion server. It is treating the HTTP headers as case sensitive. (This violates the relevant RFC.) Dart always forces the headers to lower case. In this case the server is looking for Content-Length
, but Dart sends content-length
, which the server (incorrectly) doesn't figure out are the same thing.
Luckily there's a way in Dart to force the case of headers, but you have to write a few more lines of boiler-plate. Here's a working example:

QUESTION
I deployed an nft collection on solana using metaplex and candymachine. It was working fine for 4-5 days now suddenly I am receiving this error. I was able to connect wallet and mint fine for a couple of days. I am not sure what's wrong now what I am getting 403 from rpc pool?
...Uncaught (in promise) Error: failed to get balance of account : Error: 403 Forbidden: {"jsonrpc":"2.0","error":{"code": 403, "message":"Access forbidden, contact your app developer or support@rpcpool.com."}, "id": "" }
ANSWER
Answered 2021-Dec-23 at 15:16So Metaplex and NFT calls are not allowed on the free RPCs. You'll have to use a paid provider or go with https://api.metaplex.solana.com/
If you're doing any sort of NFT drop, it is still recommended to get a paid RPC.
You shouldn't have to re-upload again, as long as you did successfully on the other RPC.

Install jsonrpc
You can use jsonrpc like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jsonrpc component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
