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
