buf := make([]byte, 16) We define an array of 16 bytes. for { n, err := reader.Read(buf) if err != nil { if err != io.EOF { log.Fatal(err) } break } fmt.Print(string(buf[0:n])) } In the for loop, we read data into the buffer with Read, and print the array ...
DESCRIPTION read() attempts to read nbyte bytes of data from the object referenced by the descriptor fildes into the buffer pointed to by buf. readv() performs the same action, but scatters the input data into the iovcnt buffers specified by the members of the iov array: iov[0], iov[1...

That is to say, compression and custom encryption and tls|kcp can be used in combination. Compression is divided into two parts, one part is local (-m) compression transmission. Part of it is compressed with the upstream (-M) transmission. ...
Usage: ajson [-mq] "jsonpath" ["input"] Read JSON and evaluate it with JSONPath. Parameters: -m, --multiline Input file/stream will be read as a multiline JSON. Each line should have a full valid JSON. -q, --quiet Do not print errors into the STDERR. Argument: jsonpath Valid ...
