Question

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。我已经成功地从SpotifyWebAPI实现了一些GET。

使用此问题解决了问题：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。

Android Spotify api respone 400
