Curl - POST request using JSON with query parameter - json

Question

I have a URL https://mylink/apply?data= for a server which accepts the data variable as valid JSON of following properties:-
name: String with your name (required)
email: String with your email address (required)
urls: Array of strings with links
comment: String with any comment/request you might have (optional)
My JSON file "data.json" is the following:
{
"data":
{
"name": "Rogers Bell",
"email": "xxxx#gmail.com",
"urls":["https://stackoverflow.com/users/3067241/imran", "https://github.com/i4ali"],
"comment":"none"
}
}
When I use the following CURL command to send a POST request, I get error code 400 Bad Request with a message from the server Error: no data passed. indicating something wrong with my JSON format or command. Not sure what I am doing wrong here
curl -v -i -X POST -d #data.json https://mylink/apply?data= -H "Accept: application/json" -H "Content-Type: application/json" -k
I am using Windows 7 if that matters

Answer 1

The API is pretty weird. But if you have to read JSON file and POST its content to server as URL parameter, you can cat the file, encode it and send it in curl. Here is an example:
curl -G -X POST https://requestb.in/1n88lah1 --data-urlencode data="$(cat input.json)"
The input.json would look like:
{
"name": "Rogers Bell",
"email": "xxxx#gmail.com",
"urls":["https://stackoverflow.com/users/3067241/imran", "https://github.com/i4ali"],
"comment":"none"
}

Answer 2

Using Postman I was able to send this POST request with the following complete URL. Got a 200 OK response
https://mylink/apply?data={
"name": "Rogers Bell",
"email": "xxxx#gmail.com",
"urls":["https://stackoverflow.com/users/3067241/imran", "https://github.com/i4ali"],
"comment":"none"
}
