Error Bitcoin API outside the band (OOB): ScantxoutSet Timare
As a developer, you probably use the “Scantxoutset” library to interact with Bitcoin Openapi (Scantxoutset). However, you have encountered a problem when the time of the OOB connection prevents the application from working smoothly. In this article, we will deepen details and provide a possible solution.
Problem: Timing the connection outside the band
When using rpcconnector.rpcconnect from Scantxoutsetset. However, if the moment of connection takes place before the API call, the connection will be considered "in the tape" and the answer will not be sent.
Code: Scantxoutset In connection Timare **
Let's take a look at your code.:
Python
Import rpcconnector
rpc_connection = rpcconnector.rpcconnect ()
json_req = [
{"Desc": "..."},
Here things could go wrong ...
]
In this example, theJson_reqdictionary contains a hollow object with a single key value. Unfortunately, the empty JSON object does not trigger problems in the "DICT" type incorporated by Python.
Problem: Python's Dictation Type and OOB
Connection
Python's "DICT" type is designed to store small amounts of data that do not require serialization or desery. In your case, because theJson_reqdictionary is empty, does not trigger problems in the Python memory aspect. However, when it went to therpcconnect () scantxoutsetset, its nature causes the connection time.
Solution: Personalized JSON request
To prevent the timing of the OOB connection, you can create a personalized JSON object that meets the scantxoutset requirements:
`Python
Import Json
json_req = {
"Desc": "...",
"Method": "Get",
"Params": {"Reqid": 123}
Replace with real query parameters ...
}
Using a non-gol dictionary, create a personalized JSON object that meets the necessary structure. This should prevent the time of OOB connection.
additional tips
- Ensure that you replace” Reqid “
with the actual interrogation parameter (s) required for your application.
- Consider the addition of errors and operating mechanisms to manage the cases in which the API call fails or often.
By modifying thejson_req` dictionary, you should be able to prevent the OOB connection from being made and ensure a easier interaction with scantxoutset.
