例子
package main
import (
"errors"
"fmt"
"io"
"net/http"
)
func main() {resp, err := http.Get("https://www.baidu.com")
if err != nil {panic(err)
}
defer func() {err = resp.Body.Close()
if err != nil {fmt.Printf("resp.Body.Close() %s", err)
}
}()
fmt.Printf("Response status code = %d\n", resp.StatusCode)
fmt.Printf("Response content type = %s\n", resp.Header.Get("Content-Type"))
fmt.Printf("Response content length = %d\n", resp.ContentLength)
body := make([]byte, resp.ContentLength)
n, err := resp.Body.Read(body)
if err != nil && !errors.Is(err, io.EOF) {panic(err)
}
fmt.Printf("Response body read = %d\n", n)
fmt.Printf("Response body = %s\n", body)
}
// $ go run main.go
// 输入如下
/**
Response status code = 200
Response content type = text/html
Response content length = 227
Response body read = 227
Response body = <html>
<head>
<script>
location.replace(location.href.replace("https://","http://"));
</script>
</head>
<body>
<noscript><meta http-equiv="refresh" content="0;url=http://www.baidu.com/"></noscript>
