【问题描述】：

目标：在 onClick() 之后创建一个名为 MonthlyTest 的播放列表

代码：

    public void createPlaylist(){
    String CREATE_PLAYLIST = "https://api.spotify.com/v1/users/"+username+"/playlists";
    JsonObjectRequest jsonRequest = new JsonObjectRequest
            (Request.Method.POST, CREATE_PLAYLIST, null, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    try {
                        MONTHLY_PLAYLIST_ID = response.getJSONArray("items").getJSONObject(0).getString("uri");
                        MONTHLY_PLAYLIST_NAME = response.getJSONArray("items").getJSONObject(0).getString("name");
                        Log.i("MainActivity", response.toString(4));
                    } catch (JSONException e) {
                        Log.e("MainActivity", "Error whilst parsing JSONObject");
                        e.printStackTrace();
                    }

                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.e("MainActivity", "Error whilst creating playlist");
                    error.printStackTrace();

                }
            }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<>();
            headers.put("Authorization", "Bearer " + token);
            return headers;
        }

        @Override
        public Map<String, String> getParams() throws AuthFailureError {
            HashMap<String, String> params = new HashMap<>();
            params.put("name", MONTHLY_PLAYLIST);
            params.put("description", "Monthly playlist with my current favourite songs.");
            params.put("public", "true");
            return params;
        }
    };
    requestQueue.add(jsonRequest);
}

错误：

使用https://developer.spotify.com/documentation/web-api/reference/playlists/create-playlist/ 作为指导，我几乎可以肯定我已经包含了所有数据，但我找不到资源来告诉我我做错了什么。我已经成功实现了一些来自 SpotifyWebAPI 的 GET。

【解决方案1】：

问题已通过以下方式解决：Android Volley: POST request - req.body inside of NodeJS REST API empty

getBody() 必须被覆盖，而不是 getParams()，因为它实际上永远不会被请求调用。
