使用Go从连接读取utf8编码的数据

Question

I can easily write a string to a connection using io.WriteString.

However, I can't seem to easily read a string from a connection. The only thing I can read from the connection are bytes, which, it seems, I must then somehow convert into a string.

Assuming the bytes represent a utf8-encoded string, how would I convert them to string form?

(Edit: alternatively, how could I simply read a string from a connection?)

Thanks!

You can just cast a slice of bytes into a string:

var foo []byte
var bar string = string(foo)

There is no encoding/decoding involved, because strings are just treated as arrays of bytes.
