This article mainly introduces "what are the data types in JSON RPC". In daily operation, I believe that many people have doubts about the data types in JSON RPC. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what data types in JSON RPC". Next, please follow the editor to study!

JSON is a lightweight data exchange format. It can represent numeric values, strings, ordered value sequences, and collections of name / value pairs.

JSON-RPC is a stateless lightweight remote procedure call (RPC) protocol. The JSON-RPC specification defines the data structure and its processing rules, which are transport-independent and therefore can be applied to socket, HTTP, WebSocket, or other messaging environments. JSON-RPC uses JSON (RFC 4627) as the data format.

Network Transport Settings for Parity

HTTP: listening on port 8545

WebSocket: listening on port 8546

IPC Socket: the listening path is $BASE/jsonrpc.ipc, and the default value on linux is ~ / .local / share/io.parity.ethereum/jsonrpc.ipc.

Data types in JSON RPC

There are several types of data that are passed using JSON. Since JavaScript/JSON does not have native byte arrays and large number types, these two types are specifically designed for Ethernet Square API, both using hexadecimal encoding, but have different formatting requirements.

When encoding a quantitative type (integer or numeric), encode as the most compact hexadecimal and use the 0x prefix, which means that 0 should be encoded as 0x0 instead of 0x00. Examples are as follows:

0x41: decimal 65

0x400: decimal 1024

0x: error! There should be at least one number, such as 0x0

0x0400: error! No leading 0 is required

Ff: error! Must use the prefix 0x

When encoding unformatted data (byte array, account address, hash, bytecode array), the encoding is hexadecimal, using the prefix 0x, and each byte is represented by two hexadecimal digits. For example:

0x41: for "A", 1 byte

0x004200: for "\ 0B\ 0", 3 bytes

0x: for "", zero byte

0xf0f0f: error! Must be even length

004200: error! Must use the prefix 0x

In addition to data and quantity, there are also standard JSON types, which we call STR (string) and INT (integer).

Enable JSON-RPC API for Parity

By default, not all API are exposed. But you can use-- jsonrpc-apis APIS to enable the corresponding API when you start Parity.

A list of API names separated by commas when APIS. Available names include: all, safe, web3, eth, net, personal, parity, parity_set, traces, rpc, parity_accounts, signer. You can use the-prefix to disable a specific api, for example: all,-personal.

The api enabled by default is web3,eth,pubsub,net,parity,parity_pubsub,traces,rpc,secretstore.
