URL encoding and decoding.

Usage:

import "github.com/gogf/gf/v2/encoding/gurl"

API Documentation:

https://pkg.go.dev/github.com/gogf/gf/v2/encoding/gurl

URL Parameter Construction

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/encoding/gurl"
    "net/url"
)

func main() {
    // Construct URL parameters
    values := url.Values{}
    values.Add("name", "gopher")
    values.Add("limit", "20")
    values.Add("page", "7")

    // Generate URL encoded query string limit=20&name=gopher&page=7
    urlStr := gurl.BuildQuery(values)
    fmt.Println(urlStr)
}

After execution, the output will be:

limit=20&name=gopher&page=7

URL Parameter Encoding and Decoding

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/encoding/gurl"
    "log"
)

func main() {
    // Encode string for safe placement in URL queries.
    encodeStr := gurl.Encode("limit=20&name=gopher&page=7")
    fmt.Println(encodeStr)

    // Perform URL decoding
    decodeStr, err := gurl.Decode("limit%3D20%26name%3Dgopher%26page%3D7")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(decodeStr)
}

After execution, the output will be:

limit%3D20%26name%3Dgopher%26page%3D7
limit=20&name=gopher&page=7

Parsing URL

component parameter value options:

Parameter Value	Description
-1	all
1	scheme
2	host
4	port
8	user
16	pass
32	path
64	query
128	fragment

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/encoding/gurl"
    "log"
)

func main() {
    // Parse URL and return its components
    data, err := gurl.ParseURL("http://127.0.0.1:8199/goods?limit=20&name=gopher&page=7", -1)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(data)
    fmt.Println(data["host"])
    fmt.Println(data["query"])
    fmt.Println(data["path"])
    fmt.Println(data["scheme"])
    fmt.Println(data["fragment"])
}

After execution, the output will be:

map[fragment: host:127.0.0.1 pass: path:/goods port:8199 query:limit=20&name=gopher&page=7 scheme:http user:]
127.0.0.1
limit=20&name=gopher&page=7
