hash.update(data[, inputEncoding])


使用给定的 data 更新哈希内容,其编码由 inputEncoding 指定。如果未提供 encoding,且 data 是字符串,则会强制使用 'utf8' 编码。如果 dataBufferTypedArrayDataView,则会忽略 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.】

这可以在流式传输时使用新数据多次调用。

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