NodeJS POST Request Over JSON-RPC

Question

I am trying to execute a POST request over JSON-RPC on my NodeJS server. Converting the following curl command:

curl -X POST --data '{"jsonrpc":"2.0","method":"personal_newAccount","params":["pass"],"id":74}' http://localhost:8545

In NodeJS I keep receiving:

200 {"id":-1,"jsonrpc":"2.0","error":{"code":-32600,"message":"Could not decode request"}}

In the header I am specifying the Content-Type. If someone can point out what I am not specifying and how to add it in it would be much appreciated.

var headers = {
    'User-Agent':       'Super Agent/0.0.1',
    'Content-Type':     'application/json-rpc',
    'Accept':'application/json-rpc'
}

var options = {
    url: "http://localhost:8545",
    method: 'POST',
    headers: headers,
    form: {"jsonrpc":"2.0","method":"personal_newAccount","params":["pass"],"id":1}
}

request(options, function (error, response, body) {
    if (!error && response.statusCode == 200) {
        res.writeHeader(200, {"Content-Type": "text/plain"});
        res.write(res.statusCode.toString() + " " + body);
    }else{
      res.writeHeader(response.statusCode, {"Content-Type": "text/plain"});
      res.write(response.statusCode.toString() + " " + error);
    }
    res.end();
})

You're missing the --header option:

curl --request POST \
    --header 'Content-type: application/json' \
    --data '{"jsonrpc":"2.0","method":"personal_newAccount","params":["pass"],"id":74}' \
    http://localhost:8545
