在Go中执行HTTP请求时出现乱码

Question

I met a Garbled string question when do Get request in Go, the code is:

req , err:= http.NewRequest(httpMethod, url,strings.NewReader(""))
req.Header.Add("Accept","application/json")
resp, err := http.DefaultClient.Do(req)
body,err := ioutil.ReadAll(resp.Body)
ret := string(body)
log.Warningf("ret: %+v", ret)

if the ret contains only english, it's correct, if contains Chinese, it has garbled string, how to solve this problem, thanks all!

Answer 1

Go strings can hold any type of characters, but when printing them the chars are interpreted as utf-8.

You can try adding:

req.Header.Add("Accept-Charset","utf-8")

If that does not work, you can try using this package to convert from whatever charset it is to utf-8:

https://godoc.org/golang.org/x/text/encoding

The charset depends on the page you are requesting. If it is html, the charset is sometimes specified like this in the response headers:

Content-Type: text/html; charset=utf-8

So you need to figure out what the charset is.
