go - Making a post request in golang -

i'm trying automate following using golang

• generate password (done)
• push notification devices (done using pushbullet)
• change wifi router password @ 192.168.0.1 (needs done)

wifi router page @ 192.168.0.1 wifi router page

here raw data captured using fiddler. (when manually changed)

post http://192.168.0.1/goform/form2wlanbasicsetup.cgi http/1.1 host: 192.168.0.1 user-agent: mozilla/5.0 (windows nt 6.3; wow64; rv:43.0) gecko/20100101 firefox/43.0 accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 accept-language: en-us,en;q=0.5 accept-encoding: gzip, deflate referer: http://192.168.0.1/d_wlan_basic.asp cookie: curshow= x-skyzip-mode: high connection: keep-alive content-type: application/x-www-form-urlencoded content-length: 233  domain=1&hiddenssid=0&ssid=home&band=9&chan=0&chanwid=1&txrate=0&method_cur=0&method=6&authtype=2&length=1&format=1&defaulttxkeyid=1&key1=&pskformat=0&pskvalue=3adi0nsxeayoi0m&checkwps2=1&save=apply&basicrates=496&operrates=4080 

and golang code follows

func routerpass(pass string) {     routerurl := "http://192.168.0.1"     resource := "/goform/form2wlanbasicsetup.cgi"     data := url.values{}     data.set("domain", "1")     data.add("ssid", "home")     data.add("band", "9")     data.add("chan", "0")     data.add("chanwid", "1")     data.add("txrate", "0")     data.add("method_cur", "0")     data.add("method", "6")     data.add("authtype", "2")     data.add("length", "1")     data.add("format", "1")     data.add("defaulttxkeyid", "1")     data.add("pskformat", "0")     data.add("pskvalue", pass)     data.add("checkwps2", "1")     data.add("save", "apply")     data.add("basicrates", "496")     data.add("operrates", "4080")      u, _ := url.parserequesturi(routerurl)     u.path = resource     u.rawquery = data.encode()     urlstr := fmt.sprintf("%v", u)       client := &http.client{}     r, _ := http.newrequest("post", urlstr, nil)     // r.header.add("authorization", "auth_token=\"xxxxxxx\"")     r.header.add("content-type", "application/x-www-form-urlencoded")     r.header.add("content-length", strconv.itoa(len(data.encode())))      resp, _ := client.do(r)     fmt.println(pass)     fmt.println(resp.status) } 

but i'm not able change password. doing wrong?

hopefully, others.

code worked

func changepassword(password string) {     hc := http.client{}     routerurl := "http://192.168.0.1/goform/form2wlanbasicsetup.cgi"     form := url.values{}     form.add("domain", "1")     form.add("hiddenssid", "0")     form.add("ssid", "linux-pc")     form.add("band", "9")     form.add("chan", "0")     form.add("chanwid", "1")     form.add("txrate", "0")     form.add("method_cur", "0")     form.add("method", "6")     form.add("authtype", "2")     form.add("length", "1")     form.add("format", "1")     form.add("defaulttxkeyid", "1")     form.add("key1", "")     form.add("pskformat", "0")     form.add("pskvalue", password)     form.add("checkwps2", "1")     form.add("save", "apply")     form.add("basicrates", "496")     form.add("operrates", "4080")     req, err := http.newrequest("post", routerurl, strings.newreader(form.encode()))     if err != nil {         panic(err)     }     req.postform = form     req.header.add("user-agent", "mozilla/5.0 (windows nt 6.3; wow64; rv:43.0) gecko/20100101 firefox/43.0")     req.header.add("referer", "http://192.168.0.1/d_wlan_basic.asp")     req.header.add("content-type", "application/x-www-form-urlencoded")      fmt.println(form)     resp, err := hc.do(req)     if err != nil {         panic(err)     }     fmt.println(resp.status)     fmt.println(password) }
