有以下的方法：使用 reflect：可以参考Feature: provide no-copy conversion from []byte to string · Issue #25484 · golang/go；不过这个因为涉及到 gc，所以实现需要非常的小心在 go1.20 之后，使用 unsafe：可以参考https://blog.devops.dev/fast-strin
但uintptr有一种特例,详见[]byte to string的方法3 二、[]byte to string 以下几种方式,可以在不重新申请底层数组的情况下将[]byte转换为string,但注意,这种方法得到的string是“可变的”,如果我们修改了[]byte的值,string的值也会被修改,因为它们指向的底层数组是同一个。 2.1 方法1,推荐 func bytes2Str(...
Avoid conversion between[]byteandstring, since this may result in memory allocation+copy. Fasthttp API provides functions for both[]byteandstring- use these functions instead of converting manually between[]byteandstring. There are some exceptions - seethis wiki pagefor more details. 大概意思就是说...

The conversion from byte slice back to string with string(b) also makes a copy, to ensure immutability of the resulting string s2. 因为string 是不可变的,所以不管是从 string 转到 []byte 还是从 []byte 转换到 string 都会发生一次复制。因此 p 和 b 可以看作两个内容相同的两个对象,对 p,b...
= nil { fmt.Println("Conversion error:", err) return } fmt.Println("Byte to int via string:", i) } 4. 测试并验证代码的正确性 运行上述代码,观察输出结果是否符合预期。例如,对于byte变量b值为100的情况,两种方法都应该输出Byte to int: 100。 5. 优化代码,确保性能和可读性 直接类型转换通常...
