nodejs chunk garbled code

When using node.js to upload or download files, we usually encounter the problem of chunk garbled characters. The so-called chunk refers to a data block. When we transfer or download a file, the file will be divided into small pieces of data for transmission. This block transmission method can reduce transmission time and traffic and improve the efficiency of file transmission. However, during the block transmission process, if we do not correctly encode and decode the data blocks, garbled characters will occur. Before dealing with the chunk garbled problem, we need to understand several concepts first. head
