getMultipleAccounts

getMultipleAccounts方法返回一组公钥的账号信息。

请求参数

• <array> - An array of Pubkeys to query, as base-58 encoded strings
• <object> - (可选) Configuration object containing the following optional fields:
  • (可选) Commitment
  • encoding: <string> - encoding for Account data, either "base58" (slow), "base64", "base64+zstd", or "jsonParsed". "base58" is limited to Account data of less than 129 bytes. "base64" will return base64 encoded data for Account data of any size. "base64+zstd" compresses the Account data using Zstandard and base64-encodes the result. "jsonParsed" encoding attempts to use program-specific state parsers to return more human-readable and explicit account state data. If "jsonParsed" is requested but a parser cannot be found, the field falls back to "base64" encoding, detectable when the data field is type .
  • (可选) dataSlice: <object> - limit the returned account data using the provided offset: and length: fields; only available for "base58", "base64" or "base64+zstd" encodings.

返回结果

结果为RpcResponse对象数组，成员可能是：

• <null> - 如果公钥账号不存在则返回此值
• <object> - 否则返回一个JSON对象包含如下字段：
  • lamports: , number of lamports assigned to this account, as a u64
  • owner: , base-58 encoded Pubkey of the program this account has been assigned to
  • data: <[string, encoding]|object>, data associated with the account, either as encoded binary data or JSON format {: }, depending on encoding parameter
  • executable: , boolean indicating if the account contains a program (and is strictly read-only)
  • rentEpoch: , the epoch at which this account will next owe rent, as u64
