Rest in taxi

[bordalix]

Fixes #290

Access taxi services via REST (removes gRPC).
Remove taxi-protobuf dependency.
Throw response (and not response.data) on broadcastTx.

@tiero please review

testing on Chrome I am getting gRPC requires HTTP/2. This most likely beacuse you are not passing content type application/json. We multiplex on the same port many protocols and switch based on content type.

We miss third parameter, with an object and a key headers where we specify application/json

strange works for you

[bordalix]

It was working because I had { assetHash } has second parameter, and when we have an object has second parameter axios adds the content-type application/json by default. My last commit introduced the error, was not properly tested. This new commit 9eaef50 fixes it. @tiero can you try it?

I tried to send 1USDt but seems it multiples wrongly to be used for coin selection

Error: Not enought coins to select 10000000049500000 f3d1ec678811398cd2ae277cbe3849c6f6dbd72c74bc542f7c4b11ff0e820958 (has: 316666666)

Yes, yesterday I notice this also, but it seems to happen on master also (can you confirm?) so it seems not related with this PR. Also, I have an idea this is addressed on @louisinger PR.

werid since I can't test the taxi topup then

but it seems to happen on master also (can you confirm?)

master seems to have outdate taxi-protobuf, therefore cant ListAssets correctly and test taxi coin selection

[bordalix]

I'm working with @louisinger to have PR #244 stable (and with Taxi REST) in order for us to be able to test it and finally merge it.
