使用jsoup搜寻网站并在golang中制作json

Question

I wanna crawl a site (bbs.archusers.ir) for making a new post or topic notification for users.

I try to write below code for a reading name, last change date, and URL every section and save into struct and save struct into JSON object. but link part in my struct won't get any value and either appear in the console for me, this is my code

    package main

import (
    "fmt"
    "github.com/anaskhan96/soup"
    "log"
    "os"
    "encoding/json"
)

type Message struct {
    Name string
    Date string
    link string

}

type myJSON struct {
    Array []Message
}

var input []Message

func main() {

    resp, err := soup.Get("https://bbs.archusers.ir")

    if err != nil {
        os.Exit(1)
    }

    doc := soup.HTMLParse(resp)
    links := doc.Find("div", "id", "brdmain").FindAll("a")
    for i := 0; i < len(links); i += 2 {
        link := Message{links[i].Text(), links[i+1].Text(), links[i].Attrs()["href"] }
        input = append(input, link)
    }


    if err != nil {
        log.Fatal(err)
    }

    jsondat := &myJSON{input}
    encjson, _ := json.Marshal(jsondat)
    fmt.Println(string(encjson))

}

which part I did wrong?

Answer 1

There is a problem in your Message struct it must name 'link' with capital k ---< Link

type Message struct {
Name string
Date string
Link string
}

and output will be correct

{"Name":"مانجارو Manjaro","Date":"2018-10-18 10:55:09","Link":"viewforum.php?id=22"}
