插槽 – golang：从套接字读取时意外的EOF

我有以下简单的golang程序来下载Google的隐私政策.不幸的是,即使文件长得多,它总是在错误的EOF之后读取6861字节而崩溃.为什么？

package main

import "net"
import "fmt"
import "io"
import "os"

func die(msg string,s os.Error) {
    fmt.Printf("%s crashed: %v\n",msg,s)
    os.Exit(1)
}

func main() {
    fd,err := net.Dial("tcp","google.com:80")
    if err != nil { die("dial",err) }

    req := []byte("GET /intl/en/privacy/ HTTP/1.0\r\nHost: www.google.com\r\n\r\n")
    _,err = fd.Write(req)
    if err != nil { die("dial write",err) }

    buf := make([]byte,1024)
    nr := 1

    for nr > 0 {
        nr,err = io.ReadFull(fd,buf)
        if err != nil { die("dial read",err) }
        fmt.Printf("read %d\n",nr)
    }
}

read 1024

read 1024
read 1024

dial read crashed: unexpected EOF
