url - Golang 中 url.openStream() 的等效函数

Question

import java.net.*;
import java.io.*;

public class URLReader {
    public static void main(String[] args) throws Exception {

    URL oracle = new URL("http://www.oracle.com/");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(oracle.openStream()));

    String inputLine;
    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);
    in.close();
}
}

我需要在 golang 中做同样的事情，即读取和打印 html 源代码，但找不到两者之间的关系，我是 Go 语言的初学者，提前谢谢你

希望这会有所帮助:

package main

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

func Error(err error) {
    if err != nil {
        log.Fatal(err)
    }
}

func main() {
    response, err := http.Get("http://www.oracle.com/")
    Error(err)

    defer response.Body.Close()

    contents, err := ioutil.ReadAll(response.Body)
    Error(err)

    fmt.Printf("%s\n", contents)
}
