Question

我无法获取网站的内容，它返回500错误。但是，如果我切换到www.google.com.hk或其他网站，那没关系。为什么？

以下是代码。

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("\n%v\n\n", string(body))
}

如果http.Get()的执行返回错误500（内部服务器错误），则很可能此错误来自服务器。事实上，让我们手动尝试。选项-D-转储标题。

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

正如您所看到的，服务器会给您一个错误500. Go完全正常;它为您提供服务器发送的错误500。如果您还有其他问题，请随时提出。

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