All,
I got puzzled by how to read a response size > 32KBytes from http
resp.Body. All I get is 32768 bytes. With either io.Read functions or
bufio.Reader.
*buffer := make([]byte, 1024)var total_bytes_read int for { len, err :=
io.ReadAtLeast(res.Body, buffer, 1024) total_bytes_read += len
log.Println(len, "bytes recevied, total received bytes: ",
total_bytes_read) if err != nil { if err == io.EOF {
log.Println("EOF: last chunk received") } else { log.Println(err)
} break } time.Sleep(1 * time.Second)} log.Println("Total bytes
received:", total_bytes_read)err = res.Body.Close()*
What I see is:
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
1024","time":"2022-06-19T19:47:48-05:00"} *
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
2048","time":"2022-06-19T19:47:49-05:00"} *
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
3072","time":"2022-06-19T19:47:50-05:00"}*
*...*
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
30720","time":"2022-06-19T19:48:17-05:00"}*
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
31744","time":"2022-06-19T19:48:18-05:00"} *
*{"level":"info","msg":"1024 bytes recevied, total received bytes:
32768","time":"2022-06-19T19:48:19-05:00"}*
Then it got stuck and waiting for return from the io.Read. Not sure if what
I did is correct. Got the same observation when using more popular
bufio.Read as well.
Thanks!
