This article introduces the knowledge of "how to use ethernet management APIs". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Manage APIs Management APIs

In addition to the official DApp APIs interface, go-ethereun provides additional management API, which uses JSON-RPC and follows the same protocol as DApp API. Geth provides a console client that can access all administrative API.

Open the management APIs

To enable the management API in the Geth RPC terminal, you need to specify the-- ${interface} api parameter on the command line at startup. The values of ${interface} can be the following three:

Rpc: used to open HTTP

Ws: used to open WebSocket

Ipc: used to open unix socket, for Unix systems or named pipe, for Windows systems

For example: geth-ipcapi admin,eth,miner-rpcapi eth,web3-rpc

Enable admin, official DApp and miner API via IPC

Open official DApp and web3 via HTTP

The HTTP RPC interface needs to be explicitly enabled through-- rpc.

Note: through the HTTP and WebSocket interfaces, any user can access these interfaces, so you must be careful when opening those interfaces. By default, Geth provides access to all API through the IPC interface, but only db, eth, net, web3-related API can be accessed through the HTTP and WebSocket interfaces.

To know which API Geth provides, you can call the modules JSON-RPC method, such as the following access via ipc on the unix system:

Echo'{"jsonrpc": "2.0", "method": "rpc_modules", "params": [], "id": 1}'| nc-U $datadir/geth.ipc

This returns all open modules, including the version number:

{"id": 1, "jsonrpc": "2.0"," result ": {" admin ":" 1.0", "db": "1.0"," debug ":" 1.0", "eth": "1.0"," miner ":" 1.0", "net": "1.0"," personal ":" 1.0" "shh": "1. 0", "txpool": "1. 0", "web3": "1. 0"}} use management APIs

These additional management API and official DApp API follow the same protocol. You can extend Web3 and use it to call these additional API.

These different methods can be divided into several logical groups. The following example is implemented through the JavaScript console, but can be easily converted into a RPC request.

For example:

Console: miner.start () IPC: echo'{"jsonrpc", "method": "miner_start", "params": [], "id": 1}'| nc-U $datadir/geth.ipcHTTP: curl-X POST-- data'{"jsonrpc": "method": "miner_start", "param": [], "id": 1} 'localhost:8545

Examples of multithreading:

Console: miner.start (4) IPC: echo'{"jsonrpc", "method": "miner_start", "params": [4], "id": 1}'| nc-U $datadir/geth.ipcHTTP: curl-X POST-- data'{"jsonrpc": "method": "miner_start", "param": [4], "id": 1} 'localhost:8545 manages API list

In addition to the official DApp API namespaces (eth, shh, web3), Geth provides the following administrative API namespaces:

Admin: Geth node (node) management

Debug: Geth node debugging

Miner: mining and DAG management

Personal: account management

Txpool: transaction pool check
