Get post data using golang http package

I am new to golang, getting familiar with http package. I am having trouble in getting the post data I am sending using postman.

http://localhost:8084/dbTest is my URI. I am passing key: hub_id value: 1 using form-data. I tried following approaches,

req.ParseForm()
fmt.Println("hub_id", req.Form["hub_id"])
req.Form.Get("hub_id")

But none of the approach work. I am getting empty response.

Following is my code:

package main

import (
    "fmt"
    "net/http"
    "log"
) 

func dbtest(w http.ResponseWriter, req *http.Request) {
  req.ParseForm()
  fmt.Println("hub_id", req.Form["hub_id"])
  req.Form.Get("hub_id")
  fmt.Println(req.PostFormValue("hub_id")) //response is empty
}

func main() {

    http.HandleFunc("/dbTest", dbtest)

  log.Fatal(http.ListenAndServe(":8084", nil))
}

When I print req i get the following:

&{POST /dbTest HTTP/1.1 1 1 map[Origin:[chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop] Connection:[keep-alive] Content-Type:[multipart/form-data; boundary=----WebKitFormBoundarydFOTVjOJMeqOHnS3] Content-Length:[138] Accept-Language:[en-US,en;q=0.8] Cache-Control:[no-cache] Accept-Encoding:[gzip, deflate] Accept:[*/*] User-Agent:[Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36] Postman-Token:[ac7ae3a9-60f6-2146-3f1c-209de7622774]] 0xc210012e70 138 [] false localhost:8084 map[] map[] <nil> map[] 127.0.0.1:34152 /dbTest <nil>}

Solution: I found the solution. Since, content-type is mulipart/form-data I correct way to parse form is to use req.ParseMultipartForm http method.

回答1:

You are using incorrect Content-Type. When using Content-Type:application/x-www-form-urlencoded, r.ParseForm() will parse data correctly. Check r.Form afterwards.

回答2:

Try

err := r.ParseForm()
v := r.Form
h := v.Get("hub_id")

Edit: I see you've tried ParseForm
