如何在Golang中为tls（httpclient）打开dsa公钥类型？

I have this code:

package main

import (
    _ "crypto/dsa"
    "crypto/tls"
    "fmt"
    "io"
    "net/http"
    "os"
    "time"
)

func main() {
    url := "https://10.11.183.9:1002/xmlinterface.asmx/CheckPSAccountBalance?id=AAA&currency=810"

    trSkipVerify := &http.Transport{
        MaxIdleConnsPerHost: 10,
        TLSClientConfig: &tls.Config{
            MinVersion:               tls.VersionSSL30,
            MaxVersion:               tls.VersionTLS10,
            PreferServerCipherSuites: true,
            InsecureSkipVerify:       true,
        },
    }

    client := http.Client{
        Timeout:   15 * time.Second,
        Transport: trSkipVerify,
    }

    resp, err := client.Get(url)
    if err != nil {
        fmt.Println(err)
        return
    }
    defer resp.Body.Close()
    io.Copy(os.Stdout, resp.Body)
}

and when i run it, i got following error message:

tls: server's certificate contains an unsupported type of public key: *dsa.PublicKey

here i found the point: https://golang.org/src/crypto/tls/handshake_client.go switch certs[0].PublicKey.(type) { by default tls client doesn't have support for dsa public key type. What can I do to solve this issue? The url above, that i'm trying to do requests is third party provider and here isn't any opportunities to do some changes on that side.

Thanks.
