sign.update(data[, inputEncoding])

• data <string> | <Buffer> | <TypedArray> | <DataView>
• inputEncoding <string> data 字符串的编码。

使用给定的 data 更新 Sign 内容，其编码在 inputEncoding 中给出。 如果未提供 encoding，且 data 是字符串，则强制为 'utf8' 编码。 如果 data 是 Buffer、TypedArray 或 DataView，则忽略 inputEncoding。

这可以在流式传输时使用新数据多次调用。

• data <string> | <Buffer> | <TypedArray> | <DataView>
• inputEncoding <string> The encoding of the data string.

Updates the Sign content with the given data, the encoding of which is given in inputEncoding. If encoding is not provided, and the data is a string, an encoding of 'utf8' is enforced. If data is a Buffer, TypedArray, or DataView, then inputEncoding is ignored.

This can be called many times with new data as it is streamed.
