(1) The request parameter [ data ] is converted into a JSON character string and is subjected to Base64 encoding;
(2) Splicing the encrypted character string, the format data character string and the request time +6 to 8-bit random numbers;
(3) Acquiring a signature value, defaulting to an SHA256 algorithm mode, and transferring a final signature value to a lower case letter;
(4) And sending the final request parameters, and converting the final request parameters into a JSON character string format.
In order to solve the technical problems, another technical scheme adopted by the invention is a using method of the block chain-based point-to-point communication API service interface, which comprises the following specific steps:
(1) The payment party generates a payment two-dimensional code of the payment party, and the payee scans the two-dimensional code of the payment party to obtain a two-dimensional code value which is walletservubkey_timestamp;
the two-dimensional code value refers to a string combination of payer server API and payer public key plus time.
(2) According to the received two-dimensional code information, the payee generates a JSON serialization string of PosOutput;
(3) The payee returns the created PaymentRequest to the payer server, and corresponding order information is generated on the payee server;
(4) The payee server sends the order information to the payer to verify the complete signed transaction, if the transaction is large, the user needs to confirm the transaction manually to ensure the safety, and then the PaymentRequest assembled by tx completed by the signature is carried out
Returning to the payee server;
(5) The payee server broadcasts after receiving the transaction, and feeds back the result to the payer server through PaymentACK, and then the payer server feeds back the result to the payer, and the payee server simultaneously informs the waiting payee to prompt the payment result.
Compared with the prior art, the technical scheme of the invention does not need to enable the collection address or account number of the collection party to be in a public state, and ensures the information security of the collection party.

Detailed Description
The following description of the embodiments of the invention is given by way of illustration and not limitation.
Fig. 1 shows a blockchain-based point-to-point communication API service interface 10, which includes an acquisition function module 101 and a broadcast function module 102, wherein the acquisition function module 101 and the broadcast function module 102 are connected by communication protocol;
the acquisition function module 101 has the function of acquiring PaymentRequest/api/showpos/getPaymentRequest,
examples: the PaymentRequest is obtained as shown in FIG. 3;
the broadcast function module 102 has the functions of broadcasting Tx/api/showpos/broadcastTx, for example: broadcast Tx as shown in fig. 4;
the invention is connected with a third party through an API interactive encryption protocol, and the specific steps are as follows:
(1) The request parameter [ data ] is converted into a JSON character string and is subjected to Base64 encoding; examples are datastr= toJson (object) - > base64 str=toBase64 Encode (jsonstr);
(2) Splicing the encrypted character string, the format data character string and the request time +6 to 8-bit random numbers; for example, sigstr=sig_str.application (dataStr) & application (time) & application (nonce);
(3) Acquiring a signature value, defaulting to an SHA256 algorithm mode, and transferring a final signature value to a lower case letter; examples:
sign＝SHA256(sigStr)
on-line matching http:// tool. Oschina. Net/encrypttype=2
Reference value SHA256 ("123456") =8d969 eef ecad3c29a3a629280e686cf0c3f5d5a86aff3ca12020c923adc6c92;
