无法通过golang http.Get（）获取内容，而是出现500错误。 为什么？

I can't get a site's content, it returns the 500 error. But if I switch to www.google.com.hk or other sites, it's OK. Why?

The following is the code.

package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
)

func main() {
    resp, err := http.Get("http://www.eqsn.gov.cn") //the browsers,IE\firefox access it is ok.
    // resp, err := http.Get("http://www.google.com.hk")  //It's ok.

    if err != nil {
        log.Fatalf("http.Get => %v", err.Error())
    }
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Printf("
%v

", string(body))
}

    If an execution of http.Get() returns an error 500 (internal server error), it is pretty likely that this error comes from the server. In fact, let's try manually. The option -D- dumps the headers.

    $ curl -D- http://www.eqsn.gov.cnHTTP/1.0 500 Internal Server Error

<p>The server encountered an internal error or

<p>Please contact the server administrator,

    As you can see, the server gives you an error 500. Go works completely fine; it gives you the error 500 the server sends. If you have further questions, feel free to ask.
