My problem: Using the command line tool to curl my localhost server while sending some data along with my POST request is not working.

What seems to be causing the error: Imagine something like this

  1. curl -i -X POST -H 'Content-Type: application/json' -d '{"data1": "data goes here", "data2": "data2 goes here"}' http:localhost/path/to/api

Result of the returning data

curl: (6) Could not resolve host: application; No data record of requested type
curl: (6) Could not resolve host: data goes here,; No data record of requested type
curl: (6) Could not resolve host: data2; No data record of requested type
curl: (3) [globbing] unmatched close brace/bracket at pos 16

After some searching i figured out that problem couldn't be the sintax used for the request since it works on UNIX shells.

Are you possibly using Windows? That so looks like a completely broken shell that doesn't properly deal with single-quotes vs double-quotes. I just tried that command line and it worked fine on my linux box. http://curl.haxx.se/mail/archive-2011-03/0066.html

I tried to work around with those " escaping it \" but it still didn't work

2.

curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data goes here\", \"data2\": \"data2 goes here\"}' http: //localhost/path/to/api

3.

curl -i -X POST -H 'Content-Type: application/json' -d '{\"data1\": \"data goes here\", \"data2\": \"data2 goes here\"}' http: //localhost/path/to/api

So i gave up. Windows seems to messing up with the JSON object sent on POST

One more alternative cross-platform solution on powershell 6.2.3:

$headers = @{
    'Authorization' = 'Token 12d119ad48f9b70ed53846f9e3d051dc31afab27'
}

$body = @"
{
    "value":"3.92.0", 
    "product":"847"
}
"@


$params = @{
    Uri         = 'http://local.vcs:9999/api/v1/version/'
    Headers     = $headers
    Method      = 'POST'
    Body        = $body
    ContentType = 'application/json'

}

The double quotes in JSON need to be escaped, and the whole JSON needs to be enclosed in double quotes. To do this without manual escaping or using an extra file for the JSON, you can use CMD's ability to replace strings in variables to escape " to \":

set json={"data1": "data goes here", "data2": "data2 goes here"}
curl -i -X POST -H 'Content-Type: application/json' -d "%json:"=\"%" http://localhost/path/to/api

We can use below Curl command in Windows Command prompt to send the request. Use the Curl command below, replace single quote with double quotes, remove quotes where they are not there in below format and use the ^ symbol.

curl http://localhost:7101/module/url ^
  -d @D:/request.xml ^
  -H "Content-Type: text/xml" ^
  -H "SOAPAction: process" ^
  -H "Authorization: Basic xyz" ^
  -X POST
