Support for custom networks

[Relfos]

Some users might need to test their dApps in a private test net, Neo-Lux must have a way to support this.

[Relfos]

Partially done, supports custom urls as API source.

Hi Relfos. Thanks for your hard work. My project may need this feature very urgently so I tried to add a function in NeoRPC.cs

public static NeoRPC ForPrivateNet(string endpoint) { return new NeoRPC(endpoint); }

But when I used the private net IP (endpoint = "http://xxx.xx.xxx.xx") I got a timeout. Did I miss something? My code called in Unity is like:

var balances = NeoRPC.ForPrivateNet("http://xxx.xx.xxx.xx").GetBalancesOf(this.keys.address);

Thanks very much!

[Relfos]

Hi @dprat0821. NeoLux is written in a way to support multiple backends. There a couple different APIs that allow interaction with the blockchain, like the "official" Neo-cli RPC, the Neon-db API and the Neo-Scan API.

Currently NeoLux only supports Neon-db API, so if you supply a custom IP address, that should be a valid Neon-db server, not a Neo-cli node. However adding support for Neo-cli should be quite fast, I will give it a try today.

[dprat0821]

Thanks Relfos. Thanks very much!

[Relfos]

Support for RPC is partially working now, so you can use it with private nets that are running Neo-cli. Only checking balances and testinvokes work, sending assets is not possible yet.

Hi Relfos, Thanks very much. Would you please advice what I can add to the latest NEO-Lux if I need to implement sending assets (tokens, gas) in private net? Documents, sample code, etc. I can try that by myself.

[Relfos]

Hi, in latest version I split the main classes into NeoRPC and NeoDB, both have same interface, with NeoDB you can do everything but you will need to have the Neon DB API running in private net, heres a link with instructions: https://gist.github.com/birmas/689c37e43c7f55745233d3aeb794f833

If using NeoRPC you just need neo-cli in private net, but sending assets does not work yet due to to neo-cli missing an api method to fetch unspent inputs of an address.

[Relfos]

With latest version it is possible to use Neo.Lux with private nets if having NeoScan installed at the privatenet: https://github.com/slipo/neo-scan-docker

Hi Relfos, I am using Neo.Lux to invoke the smart contract on private chain (attached file). I debugged and saw response.state = FAULT and response.transaction = null, it means it could not add data to private chain, is it right? how can I test my smart contract with Neo.Lux on private chain? When you are available, please have a look then give me a hand. Thank you for your time.

[Relfos]

A nul transaction means that either there was a network failure or the RPC node rejected the transaction. Do you have GAS and NEO in this address? Or you might need to specify a RPC URL and port for private net instead of the default values

Hi Relfos, Thank you for your feedback. Yes, there are a lots of NEO and GAS. I give you some the screenshots that what I did.

Hi Relfos, I am using NeoLux with NeoScan on Private net, I can get asset balance with NEO 100,000,000 and GAS 16,024 by using api.GetAssetBalancesOf(keys.address). Now I try to deploy smart contract by using api.DeployContract(...) method we expect to see an output for the "result" parameter as true but we keep returning false. Could you please look at these screenshots and give us some feedback. thank you for your help.

[Relfos]

Hi, I don't think thats a valid value for the 'paras' variable, the chain might refuse that.

Hi Relfos, Thank you so much for your feedback. I try to create another contract with string parameter type, but still get the same result = false. Is these some thing missing? When you are available, please give me a hand. Thank you so much for your help.

[Relfos]

It is possible that something changed in NEO recently. Try deploy the contract using NEO-gui first

Hi @Relfos Relfos, Thank you for your quick reply. I will have a try. Have a nice day.

Hi @Relfos , Just give you an update. After restart docker, It works well now. Thank you so much for your help.

Hi @Relfos , After I deployed smart contract successfully. Then I try to add data to Private chain by calling the SetHello method, follow the debugger I got the result with state = FAULT and stack = empty. When you are available, please have a look then give some advice. Thank you for your help.

[Relfos]

Try providing a reversed scripthash string

Hi @Relfos , Thank you for your feedback. I have tried providing a reversed scripthash string "0x884fd32dba7e664627f16312dd544847d41e7094", but still got the same result. When you are available, please have a look then give me some advice. Thank you so much. Have a nice day.

Hi @Relfos , Finally I tried to debug and found out the issue that if using void Main(string operation), there was an error message at Neo.VM (look at a screenshot) then I changed to bool Main(string operation), it works fine. Just give you an update. Thank you so much for your help and have a nice weekend.
