| --------- | --------------- | ----------------------------------------------------- |
| block\_id | BlockIdentifier | 区块 ID,可以是区块号、区块哈希或 'latest','earliest','pending' 等标识符 |

## 返回值

返回 BlockInformationData 对象,包含以下字段:

| 字段            | 类型                                             | 说明         |
| ------------- | ---------------------------------------------- | ---------- |
| block\_hash   | HexBytes                                       | 区块哈希       |
| block\_number | BlockNumber                                    | 区块高度       |
| timestamp     | Timestamp                                      | 区块时间戳      |
| miner         | ChecksumAddress                                | 矿工地址       |
| gas\_used     | int                                            | 区块已使用的 Gas |
| gas\_limit    | int                                            | 区块 Gas 上限  |
| transactions  | Union\[Sequence\[HexBytes], Sequence\[TxData]] | 区块内的交易列表   |

## 示例代码

```python
# 获取最新区块信息
latest_block = chain.get_block_information("latest")
print(f"Block Number: {latest_block.block_number}")
print(f"Block Hash: {latest_block.block_hash.hex()}")
print(f"Miner: {latest_block.miner}")
print(f"Gas Used: {latest_block.gas_used}")

# 通过区块号获取
block = chain.get_block_information(12345678)

# 通过区块哈希获取
block = chain.get_block_information("0x...")
```
