How do I get the response from the "application/x-www-form-urlencoded" form in the console?

[lolo02afon]

Please tell me why in the code from the documentation https://github.com/labstack/echox/blob/master/website/content/guide.md#form-applicationx-www-form-urlencoded:

package main

import (
	"net/http"

	"github.com/labstack/echo"
)

func save(c echo.Context) error {
	// Get name and email
	name := c.FormValue("name")
	email := c.FormValue("email")
	return c.String(http.StatusOK, "name:"+name+", email:"+email)
}
func main() {
	e := echo.New()
	e.POST("/save", save)
	e.Logger.Fatal(e.Start(":1323"))
}

..after executing the command in the console: $ curl -d "name=Joe Smith" -d "email=joe@labstack.com" http://localhost:1323/save gives an error: curl: (7) Failed to connect to localhost port 1323 after 2232 ms: Connection refused instead of: => name:Joe Smith, email:joe@labstack.com as it says in Echo manual? What am I doing wrong?

This depend on your OS and network settings. I would assume that localhost is not correctly resolved in you machine. If you are using Linux check your /etc/hosts file. try using e.Start("localhost:1323") and try pinging localhost. sudo netstat -tlpen | grep 1323 would tell you where that Go programm is actually running

Это зависит от вашей ОС и настроек сети. Я бы предположил, что localhostэто не правильно разрешено в вашей машине. Если вы используете Linux, проверьте /etc/hostsфайл. попробуйте использовать e.Start("localhost:1323") и попробуйте пропинговать localhost. sudo netstat -tlpen | grep 1323расскажет вам, где на самом деле работает эта программа Go

I have Windows. I replaced // e.Logger.Fatal(e.Start(":1323")) with e.Logger.Fatal(e.Start("localhost:1323")), ran the `` command in the terminal again, and I get another error:

Invoke-WebRequest : The parameter cannot be bound because the parameter "d" is specified more than once. To specify multiple parameter values that allow
multiple values, use the array syntax. For example, "-parameter value1,value2,value3".
string:1 character:26
+ curl -d "name=Joe Smith" -d "email=joe@labstack.com" http://localhost ...
+                          ~~
    + CategoryInfo          : InvalidArgument: (:) [Invoke-WebRequest], ParameterBindingException
    + FullyQualifiedErrorId : ParameterAlreadyBound,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

And replacing -d with -parameter, i.e. entering curl -parameter "name=Joe Smith", "email=joe@labstack.com" http://localhost:1323/save, I also get an error.

@lolo02afon you are really asking questions that are not related to Echo.

First thing that I found by googling https://stackoverflow.com/questions/45183355/invoke-webrequest-cannot-bind-parameter-headers seems that curl is an alias on Windows to some Invoke-WebRequest thingie and not curl command

NB: your "github.com/labstack/echo" import is wrong, it should be "github.com/labstack/echo/v4"

[lolo02afon]

NB: ваш "github.com/labstack/echo"импорт неверен, он должен быть"github.com/labstack/echo/v4"

The thing is that I downloaded Echo through the command go get github.com/labstack/echo and I can only import github.com/labstack/echo, otherwise I get an error. I'm a newbie and not sure, but I don't think this is the error, because the server works and outputs content in the browser and when I start it up it says v4.7.2 is installed. Of course I would love to reinstall exactly to v4, but I can't find an answer how yet. Maybe you can tell me)

Please see https://github.com/labstack/echo#installation

I stayed to install using go get github.com/labstack/echo/v4, but it gives an error:

cannot find package "github.com/labstack/echo/v4" in any of:
C:\Program Files\Go\src\github.com\labstack\echo\v4 (from $GOROOT)
C:\Users\lol20\go\src\github.com\labstack\echo\v4 (from $GOPATH)

despite the fact that the Golang version go version go1.19 windows/amd64.
And go get github.com/labstack/echo works.

It turned out that the problem was that I made a mistake when creating the project, and entering the command go mod init myapp ignored the answer go: modules disabled by GO111MODULE=off; see 'go help modules' and proceeded. Fixed it and now everything works. I know it's stupid and thank you for wanting to help.
