如何在HTTP请求中获取数组

Question

For this request GET http://localhost:8080/path?my_key%5B%5D=3&my_key%5B%5D=4&my_key%5B%5D=5

I can't get the data from my_key. I tried req.URL.Query()["my_key"]. I can get it if I change the request encoding to from my_key%5B%5D=4&my_key%5B%5D=5 to my_key=4&my_key=5

How can I get request URL's in form of my_key[]=value

Answer 1

Use the net/url package

package main

import (
    "fmt"
    "net/url"
)

func main() {
    utmp := "GET http://localhost:8080/path?my_key%5B%5D=3&my_key%5B%5D=4&my_key%5B%5D=5"
    u, err := url.Parse(utmp)
    if err != nil {
        panic(err)
    }
    fmt.Println(u.Query()["my_key[]"])
}

Your key is "my_key[]" not "my_key"
