This addresses task 4 in issue 4257.
bisq-network#4257
This PR should be reviewed/merged after PR 4304.
bisq-network#4304
This new gRPC PaymentAccounts service method creates a dummy
PerfectMoney payment account for the given name, number and fiat
currency code, as part of the required "simplest possible trading
API" (for demo). An implementation supporting all payment
methods is not in the scope.
Changes specific to the new rpc method implementation follow:
* New createpaymentacct method + help text was added to CliMain.
Help text formatting was also changed to make room for larger
method names and argument lists.
* The PaymentAccount proto service def was renamed PaymentAccounts
to avoid a name collision, and the new rpc CreatePaymentAccount
was made part of the newly named PaymentAccounts service def.
* New GrpcPaymentAccountsService (gRPC boilerplate) and
CorePaymentAccountsService (method implementations) classes were
added.
* The gRPC GetPaymentAccountsService stub was moved from GrpcServer
to the new GrpcPaymentAccountsService class, and
GrpcPaymentAccountsService is injected into GrpcServer.
* A new createpaymentacct unit test was added to the bats test
suite (checks for successful return status code).
Maybe bit out of scope, some small changes were made towards making
sure the entire API is defined in CoreApi, which is used as a
pass-through object to the new CorePaymentAccountsService. In the
next PR, similar refactoring will be done to make CoreApi the
pass-through object for all of the existing CoreWalletsService
methods. (CoreWalletsService will be injected into CoreApi.)
In the future, all Grpc*Service implementations will call core
services through CoreApi, for the sake of consistency.- Loading branch information
