hash.update(data[, inputEncoding])

使用给定的 data 更新哈希内容,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 dataBufferTypedArrayDataView,则忽略 inputEncoding


Updates the hash 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.
