http new request with POST method value is blank

I am using below code to for POST method:

postData := url.Values{}
postData.Set("login_id", "test1")
postData.Set("api_key", "test2")

req, err := http.NewRequest("POST","http://example.com", strings.NewReader(postData.Encode()))

client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
    return nil, err
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
logger.Info(string(body))
os.Exit(3)

Values are not being set. When I checked with this: logger.Info(req.PostFormValue("login_id")) there is a blank value. How can I debug/solve this issue?

You need to specify the request's Content-Type with req.Header.Set("Content-Type", "application/x-www-form-urlencoded").

postData := url.Values{}
postData.Set("login_id", "test1")
postData.Set("api_key", "test2")

req, err := http.NewRequest("POST", "http://localhost:8080/", strings.NewReader(postData.Encode()))
if err != nil {
    panic(err)
}

req.Header.Set("content-type", "application/x-www-form-urlencoded")
fmt.Println(req.PostFormValue("login_id"))

Of course they are. But that does not mean these values are not sent.

PostFormValue is used to access the form values on a server Request and not on a client Request as your's req.

PostForm is below.

package main

import (
    "io/ioutil"
    "net/http"
    "net/url"
)

func main() {
    resp, err := http.PostForm(URL, url.Values{"login_id": {"test1"}, "api_key": {"test2"}})
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    respBody, err := ioutil.ReadAll(resp.Body)
    if err == nil {
        str := string(respBody)
        println(str)
    }
}
