Configurations for DApp Testing

AionR Kernel, by default, only support local connection and does not allow any tool or website to connect to the Kernel.

Default Configuration:

[http]
interface = "local"
hosts = ["none"]    #  equivalent to []
cors = ["none"]     #  equivalent to []

[websockets]
interface = "local"
origins = ["none"]  #  equivalent to []
hosts = ["none"]    #  equivalent to []

Enable Remote Connections

In order to let DApps and other tools connect to the Kernel remotely, edit configuration interface field in each section:

• interface = "local" or interface = "127.0.0.1" only allows the connections to "127.0.0.1" or "localhost";
• interface = [public IP address] only allows the connections to that public address;
• interface = "0.0.0.0" allows all the connections.

Enable Connections from Other Hosts and Tools

In order to let other web hosts communicate with AionR Kernel, you need to add the hostname into the hosts field in [rpc] and [websockets] section; if you want to grant permission for all websites, let hosts = ["all"].

Kernel, by default, enabled Cross-Origin Resource Sharing. To make sure other developing tools or extension tools connect to Kernel, edit configuration cors field in [rpc] section or origins field in [websockets]:

• cors = ["none"] and origins = ["none"] does NOT allow any origin;
• cors = ["all"] and origins = ["all"] allows requests from any origin;
• cors = ["chrome-extension://*","moz-extension://*"] and origins = ["chrome-extension://*","moz-extension://*"] allows the requests from chrome and firefox extensions.
