用Go编码UTF-8 [英] Encoding UTF-8 with Go

问题描述

  pwd =abc123;我想在Go中找到相当于下面的C＃代码。 
 encoding = Encoding.UTF8; 
 SHA1 sha1 = SHA1.Create（）; 
 byte [] hash = sha1.ComputeHash（encoding.GetBytes（text））; 
  

我知道有一个 crypto / sha1 软件包。我知道我可以运行：

  pwd：=abc123
 hasher：= sha1.New（）// SHA1.Create（）; 
 hasher.Write（[] byte（pwd））// sha1.ComputeHash但没有UTF8编码？ 
  

我不确定如何在散列时获得正确的编码。我想知道是否可以得到一些帮助来转换这个

解决方案

根据文档：

一个没有字节级转义的字符串文字总是保存有效的UTF-8
序列。

因此，如果在Golang源代码中，则不需要将字符串编码为utf8。但是，如果字符串来自输入，那么 utf8 包是您的朋友。

I am trying to find the equivalent of the following C# code in Go.

pwd = "abc123";
encoding = Encoding.UTF8;
SHA1 sha1 = SHA1.Create();
byte[] hash = sha1.ComputeHash(encoding.GetBytes(text));

I know that there is a crypto/sha1 package within Go. I know I can run:

pwd := "abc123"
hasher := sha1.New() // SHA1.Create();
hasher.Write([]byte(pwd)) // sha1.ComputeHash but without encoding in UTF8 ?

I am not sure how I can get the correct encoding when hashing. I was wondering if I could get some help converting this

解决方案

According to the documentation:

A string literal, absent byte-level escapes, always holds valid UTF-8 sequences.

So you don't need to encode into utf8 the string if is inside the Golang source code. However, if the string comes from an input, the utf8 package is your friend.
