digest: algorithm is not supported

[B190102B]

代码：

	_, err := req.DevMode().R().SetDigestAuth("username", "password").Put(url)
	if err != nil {
		panic(err)
	}

Output:

panic: digest: algorithm is not supported

req 无法识别 algorithm="MD5"，
想请问为什么 c.algorithm 不使用 strings.Trim

digest.go:

func parseChallenge(input string) (*challenge, error) {
	const ws = " \n\r\t"
	const qs = `"`
	s := strings.Trim(input, ws)
	if !strings.HasPrefix(s, "Digest ") {
		return nil, errDigestBadChallenge
	}
	s = strings.Trim(s[7:], ws)
	sl := strings.Split(s, ",")
	c := &challenge{}
	var r []string
	for i := range sl {
		r = strings.SplitN(strings.TrimSpace(sl[i]), "=", 2)
		if len(r) != 2 {
			return nil, errDigestBadChallenge
		}
		switch r[0] {
		case "realm":
			c.realm = strings.Trim(r[1], qs)
		case "domain":
			c.domain = strings.Trim(r[1], qs)
		case "nonce":
			c.nonce = strings.Trim(r[1], qs)
		case "opaque":
			c.opaque = strings.Trim(r[1], qs)
		case "stale":
			c.stale = r[1]
		case "algorithm":
			// Here
			c.algorithm = r[1]
		case "qop":
			c.qop = strings.Trim(r[1], qs)
		case "charset":
			if strings.ToUpper(strings.Trim(r[1], qs)) != "UTF-8" {
				return nil, errDigestCharset
			}
		case "userhash":
			c.userhash = strings.Trim(r[1], qs)
		default:
			return nil, errDigestBadChallenge
		}
	}
	return c, nil
}

应该是实现上的小失误，已修复，可升级到最新试试
