编码/解码 URL

本文介绍了编码/解码 URL的处理方法，对大家解决问题具有一定的参考价值

问题描述

在 Go 中编码和解码整个 URL 的推荐方式是什么?我知道 url.QueryEscape 和 url.QueryUnescape 方法，但它们似乎并不是我正在寻找的.具体来说，我正在寻找像 JavaScript 的 encodeURIComponent 和 decodeURIComponent 之类的方法.

What's the recommended way of encoding and decoding entire URLs in Go? I am aware of the methods url.QueryEscape and url.QueryUnescape, but they don't seem to be exactly what I am looking for. Specifically I am looking for methods like JavaScript's encodeURIComponent and decodeURIComponent.

谢谢.

推荐答案

您可以使用 net/url 模块.它不会为 URL 的各个部分分解单独的编码函数，您必须让它构建整个 URL.仔细观察源代码后，我认为它做得非常好且符合标准.

You can do all the URL encoding you want with the net/url module. It doesn't break out the individual encoding functions for the parts of the URL, you have to let it construct the whole URL. Having had a squint at the source code I think it does a very good and standards compliant job.

这是一个例子(playground 链接)

package main

import (
    "fmt"
    "net/url"
)

func main() {

    Url, err := url.Parse("http://www.example.com")
    if err != nil {
        panic("boom")
    }

    Url.Path += "/some/path/or/other_with_funny_characters?_or_not/"
    parameters := url.Values{}
    parameters.Add("hello", "42")
    parameters.Add("hello", "54")
    parameters.Add("vegetable", "potato")
    Url.RawQuery = parameters.Encode()

    fmt.Printf("Encoded URL is %q
", Url.String())
}

打印什么

Encoded URL is "http://www.example.com/some/path/or/other_with_funny_characters%3F_or_not/?vegetable=potato&hello=42&hello=54"
