GoLang 1.6 - HTTPS EOF错误

Question

我目前正在尝试通过GoLang 1.6发布HTTP POST来调试问题。

连接失败并显示“EOF”错误。

测试客户端代码：https://gist.github.com/fatmcgav/35d1a4fbd74c7208f445c487f756a5e1

package main

import (
    "bytes"
    "crypto/tls"
    "encoding/json"
    "fmt"
    "net/http"
    "net/http/httputil"
    "os"
)

func main() {

    const body = "{\"auth\":" +
        "{\"identity\":" +
        "{\"methods\":[\"password\"]," +
        "\"password\":" +
        "{\"user\":{\"name\":\"xxx\"," +
        "\"password\":\"xxx\"," +
        "\"domain\":{\"name\":\"xxx_domain\"}" +
        "}" +
        "}" +
        "},\"scope\":{\"project\":" +
        "{\"domain\": " +
        "{\"name\":\"xxx_domain\"},\"name\":\"xxx\"}}}}"

    // Unmarshall JSON
    var m map[string]interface{}
    json.Unmarshal([]byte(body), &m)
    // fmt.Println("%v", m)

    var req *http.Request
    var resp *http.Response
    var dump []byte
    var err error
    client := &http.Client{}

    url := "https://identity.xxx/v3/auth/tokens"

    fmt.Println("Requesting auth token against URL: %s", url)

    rendered, err := json.Marshal(m)
    if err != nil {
        fmt.Println("Error marshalling body: %q", err)
        os.Exit(2)
    }

    req, err = http.NewRequest("POST", url, bytes.NewReader(rendered))
    if err != nil {
        fmt.Println("Got an error: %q", err)
        os.Exit(2)
    }

    // Need to Close connection
    req.Close = true

    fmt.Println("Setting Insecure TLS mode")
    // Configure custom TLS settings.
    config := &tls.Config{InsecureSkipVerify: true}
    transport := &http.Transport{TLSClientConfig: config,
        DisableKeepAlives:  true,
        DisableCompression: true,
    }
    client.Transport = transport

    req.Header.Set("Content-Type", "application/json")
    req.Header.Set("Accept", "application/json")

    dump, err = httputil.DumpRequestOut(req, true)
    fmt.Printf("Outgoing requst = \n%q\n", dump)

    resp, err = client.Do(req)
    if err != nil {
        fmt.Println("Error encountered: %q", err)
    }
    dump, err = httputil.DumpResponse(resp, true)
    fmt.Printf("Response = \n%q\n", dump)
}

结果输出在这里：

 ~/golang/scripts  go build req-test.go && ./req-test

出于显而易见的原因，我已经匿名了一些细节......

关于我做错的任何指示......
