使用golang http包获取发布数据 [英] Get post data using golang http package
问题描述
我是golang的新手,熟悉http包。
http:// localhost:8084 / dbTest $ c $我无法获取邮递员发送的邮递资料。 c>是我的URI。我使用表单数据传递键:
hub_id
值: 1
。我尝试了下面的方法,
req.ParseForm()
fmt.Println(hub_id,req.Form [ hub_id])
req.Form.Get(hub_id)
但是没有的方法工作。
以下是我的代码:
包主要
导入(
fmt
净/ http
记录
)
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))//响应为空
}
func main(){
http.HandleFunc(/ dbTest,dbtest)
log.Fatal(http.ListenAndServe(:8084,nil))
}
当我打印请求时,我得到以下内容:
& {POST / dbTest HTTP / 1.1 1 1 map [Origin:[chrome-extension:// fhbjgbiflinjbdggehcddcbncdddomop] Connection:[keep-alive] Content-Type:[multipart / form-data;边界= ---- WebKitFormBoundarydFOTVjOJMeqOHnS3]内容长度:[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,如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>}
解决方案:我找到了解决方案。因为内容类型是 mulipart / form-data
我正确的解析表单的方式是使用 req.ParseMultipartForm
http方法。
您正在使用不正确的 Content-Type
。当使用 Content-Type:application / x-www-form-urlencoded
, r.ParseForm()
将解析数据正确。之后检查 r.Form
。
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.
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.
