eth_newFilter

根据过滤器器选项创建过滤器对象，以便在状态更改（日志）时通知。要检查状态是否已更改，请调用eth getfilterchanges。

关于指定主题过滤器的说明:

关于特定主题过滤器的说明:主题是顺序相关的。如果一个交易的日志有主题[A, ，那么将被以下的主题过滤器匹配:

[]任何主题
[A]先匹配A主题
[null,B]先匹配其他主题，再匹配B主题
[A,B]先匹配A主题，再匹配B主题，最后匹配其他主题
[[A,B][A,B]"先匹配A主题或B主题，再匹配A主题或B主题,最后匹配其他主题"]

参数

fromBlock: QUANTITY|TAG - 可选，默认值:"latest"。整数块编号，或字符串"latesr"表示最后挖出的块，"pending"或"earliest"用于未挖出的交易。

toBlock: QUANTITY|TAG - 可选，默认值:"latest"。整数块编号，或字符串"latesr"表示最后挖出的块，"pending"或"earliest"用于未挖出的交易。
address: DATA|Array, 20 字节 - 可选，合约地址或生成日志的一组地址
topics: Array of DATA, - 可选，32 字节主题数组，每个主题可以是数组或使用 or 选项连接
