Golang byte-to-byte array-to-string problem

This is a creation in Article, where the information may have evolved or changed.

Golang language itself is a tool set of C, the development of C programs used by most of the structure, memory management, Ctrip and so on, Golang basically have, he just on this basis added some concepts here to say a very small problem, is a byte array to string problem, Most of the internet is like this (including Google):string(P[:]), this turn over is a problem, Let's take a look at the structure of string:

struct String
{
byte* str;
Intgo Len;
};

This structure reminds me of the Nginx string, which he defines:

typedef struct {
size_t Len;
U_char *data;
} ngx_str_t;

Golang inside the concept of string is actually not encountered before the concept of the end, he is actually a continuous memory, the first address + length, the above assignment, if p inside has, he will not do this time, if the string to do other processing may be a problem, Like StrConv. Atoi to int there is an error, the solution is to write a formal conversion function:

Func byteString (P []byte) string {
For I: = 0; i < Len (p); i++ {
If p[i] = = 0 {
return string (P[0:i])
}
}
return string (p)
}

So it won't be a problem.
