You need to manually set the content header and the body of the message, and convert your form data string to a json string and send how parameter to CallLogin:

public IEnumerator CallLogin(string url, string logindataJsonString)
{
    var request = new UnityWebRequest (url, "POST");
    byte[] bodyRaw = Encoding.UTF8.GetBytes(logindataJsonString);
    request.uploadHandler = (UploadHandler) new UploadHandlerRaw(bodyRaw);
    request.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer();
    request.SetRequestHeader("Content-Type", "application/json");
    yield return request.SendWebRequest();

    if (www.error != null)
    {
        Debug.Log("Erro: " + www.error);
    }
    else
    {
        Debug.Log("All OK");
        Debug.Log("Status Code: " + request.responseCode);
    }

}
