编码/解码URL [英] Encode / decode URLs
问题描述
url.QueryEscape
和 url.QueryUnescape
,但它们似乎并不完全是我在寻找。具体来说,我正在寻找JavaScript的 encodeURIComponent
和 decodeURIComponent
的方法。 谢谢。
您可以使用 net / url 模块。它不会分解URL的各个编码功能,您必须让它构建整个URL。在源代码中有一个眯眼,我认为这是一个非常好的和符合标准的工作。
这是一个例子( playground link )
package main
import(
fmt
net / url
)
func main(){
var url * url.URL
Url,err:= url.Parse(http://www.example.com)
如果err!= nil {
panic(boom )
}
Url.Path + =/ some / path / or / other_with_funny_characters?_or_not /
参数:= url.Values {}
参数。
parameters.Add(hello,54)
parameters.Add(vegetable,potato)
Url.RawQuery = parameters.Encode()
fmt.Printf(Encoded URL is%q\\\
,Url.String())
}
哪个打印
编码的URL是http: //www.example.com/some/path/or/other_with_funny_c人物%3F_or_not /?蔬菜=土豆& hello = 42& hello = 54
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
.
Thanks.
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.
Here is an example (playground link)
package main
import (
"fmt"
"net/url"
)
func main() {
var Url *url.URL
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\n", Url.String())
}
Which prints
Encoded URL is "http://www.example.com/some/path/or/other_with_funny_characters%3F_or_not/?vegetable=potato&hello=42&hello=54"
