Calculate how many BTC an address own from RPC calls

[TheWolf666]

It seems that there is a problem specific to windows.

For example

This is working on Unix

Code:

./bitcoin-cli scantxoutset start  '["addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)"]'

But this is not on windows

Code:

bitcoin-cli.exe scantxoutset start  '["addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)"]'

error: Error parsing JSON:'[addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)]'

Escaping like this bitcoin-cli.exe scantxoutset start  '[\"addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)\"]'
does not change anything, it fails.

Any clue?

It'll be the way that the Windows "shell" is interpreting the characters... are you using cmd.exe/"command prompt" or powershell?

The format for using scantxoutset on the Windows command prompt seems to be:

Code:

bitcoin-cli.exe scantxoutset start [\"addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)\"]

Actually you are right, it is working, I am using cmd because I call it from PHP and that's what it does.,
Here is the solution:

From the command prompt, no " or ' are accepted.

Code:

bitcoin-cli.exe scantxoutset start [\"addr(1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2)\"]

From PHP retval is an array with the response and $r is the return code true or false

Code:

$address="1CUTyyxgbKvtCdoYmceQJCZLXCde5akiX2";
$s='bitcoin-cli.exe scantxoutset start [\"addr('.$address.')\"] ';
exec($s,$retval,$r);

This solution is working but it sucks because it is really slow compared to RPC.
I could not get a positive result with any JSON formatted submission to RPC.

In Windows' command prompt, the left and right parentheses are considered special characters and have to be escaped with a ^ character, not a backslash. They are not special in Linux which is why it works there. So try escaping those in your RPC call and try it again.

The Windows command-line interpreter uses a caret character (^) to escape reserved characters that have special meanings (in particular: &, |, (, ), <, >, ^).[4] The DOS command-line interpreter, though it has similar syntax, does not support this.
