I am trying RPC API. Here is the code which I am using on cmd for testing a dummy transaction.

curl --request POST --url http://localhost:8080/v1/chain/push_transaction --header 'accept: application/json' --header 'content-type: application/json' --data '{"signatures":["EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC"],"compression":false,"packed_context_free_data":"00","packed_trx":"00"}'

But each time I get same error message:

{"code":500,"message":"Internal Service Error","error":{"code":3010010,"name":"packed_transaction_type_exception","what":"Invalid packed transaction","details":[{"message":"Invalid packed transaction","file":"chain_plugin.cpp","line_number":1562,"method":"push_transaction"},{"message":"pivot != std::string::npos: No delimiter in string, cannot determine type: EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC","file":"signature.cpp","line_number":20,"method":"parse_base58"},{"message":"error parsing signature","file":"signature.cpp","line_number":28,"method":"parse_base58"},{"message":"Failed to deserialize variant","file":"abi_serializer.hpp","line_number":697,"method":"from_variant"}]}}

Not sure what is wrong there. I want to use it in one PHP application so RPC is important for me.

UPDATE

Then tried solution with SIG_K1_ and SIG_R1_ also.

curl --request POST --url http://localhost:8080/v1/chain/push_transaction --header 'accept: application/json' --header 'content-type: application/json' --data '{"signatures":["SIG_K1_EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC"],"compression":false,"packed_context_free_data":"00","packed_trx":"00"}'

But it throw some different error like below.

{"code":500,"message":"Internal Service Error","error":{"code":3010010,"name":"packed_transaction_type_exception","what":"Invalid packed transaction","details":[{"message":"Invalid packed transaction","file":"chain_plugin.cpp","line_number":1562,"method":"push_transaction"},{"message":"Unable to decode base58 string EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC","file":"base58.cpp","line_number":625,"method":"from_base58"},{"message":"error parsing signature","file":"signature.cpp","line_number":28,"method":"parse_base58"},{"message":"Failed to deserialize variant","file":"abi_serializer.hpp","line_number":697,"method":"from_variant"}]}}

FYI, I am using cleos wallet keys to see the signature.

You are adding the public Key as your signature instead of signature itself and you have to provide a signature-base-prefix/signature-prefix because you can use different curve-algorithms to create keys (R1/K1).

... "signatures":["EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC"]...

must be

..."signatures":["SIG_K1_SIGNATUREJH1J2j124235HJWEHFE"]...

or

..."signatures":["SIG_R1_SIGNATUREJH1J2j124235HJWEHFE"]...

  • Unable to decode base58 string EOS4wJVpa8YBT1BnBtGHXM8PgQr9cxD2TuZVGhciLZZwp4AsjStoC New error is something like this with STG_K1 or STG_R1. Oct 22, 2019 at 10:49

  • sry, my fault. Obviously you are adding the key as the signature - but you have to add the signature instead.

  • You mean the openssl signature for my local machine? Or something else? Where can I find it? Oct 22, 2019 at 12:07
  • You need to generate a signature based on base58-transaction-hash and your private-key. OpenSSL doesn't support the ECDSA needed and unfortunately I'm not a php-dev. Have you seen this one? packagist.org/packages/manamine/php-eos-rpc-sdk
