java - Facebook Graph API : querying/me/photos works fine, 但/me/photos?limit=100 返回错误

Question

我试过查询状态、喜欢、照片，一切正常。

但是当我在字符串的末尾添加一个限制“?limit=100”时，我从响应对象中得到错误类型:OAuthException，errorMessage:必须使用 Activity 访问 token 来查询有关当前的信息用户

我的代码的相关部分如下:

Request rq3 = new Request(Session.getActiveSession(), "/me/statuses?limit=100", null, HttpMethod.GET, new Request.Callback() {
            @Override
            public void onCompleted(Response response) {
                parseFeed(response, 2);
                getNext(response, 2);
            }
        });
        rq3.executeAsync();


private void parseFeed(Response response, int type) {
    try {
        Log.v("response", response.toString());
        JSONArray feedArr = response.getGraphObject().getInnerJSONObject().getJSONArray("data");
        switch(type) {
        case 0:

            numLikes += feedArr.length();
            likesView.setText("Likes: " + String.valueOf(numLikes));
            break;
        case 1:
            numPhotos += feedArr.length();
            photosView.setText("Photos: " + String.valueOf(numPhotos));
            break;
        case 2:
            Log.v("response", response.toString());
            numStatuses += feedArr.length();
            statusesView.setText("Statuses: " + String.valueOf(numStatuses));
            break;
        }

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

private void getNext(Response response, final int type) {
    Request next = response.getRequestForPagedResults(Response.PagingDirection.NEXT);
    if (next != null) {
        Log.v("status", "getting next");
        next.setCallback(new Request.Callback() {
            @Override
            public void onCompleted(Response response) {
                // TODO Auto-generated method stub
                parseFeed(response, type);
                getNext(response, type);
            }
        });
        Request.executeBatchAsync(next);
    }
    else {
        Log.v("status", "ended");
    }
}

Answer 1

Request(Session, String, Bundle, HttpMethod, Callback)

parameters Additional parameters to pass along with the Graph API request; parameters must be Strings, Numbers, Bitmaps, Dates, or Byte arrays.

根据doc , 参数不应是图形路径的一部分。您实际上传递了一个 null Bundle。

正确的用法:

Bundle params = new Bundle();
params.putString("limit", 100);

Request rq3 = new Request(Session.getActiveSession(),
                          "/me/statuses",                         
                          params,                         
                          HttpMethod.GET,                 
                          new Request.Callback() {
                              @Override
                              public void onCompleted(Response response) {
                                  parseFeed(response, 2);
                                  getNext(response, 2);
                              }
                          }
                     );
