sign.update(data[, inputEncoding])


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 dataBufferTypedArrayDataView,则忽略 inputEncoding

¥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.

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.
