private void postToWall(String msg) {

            parameters.putString(Facebook.TOKEN, facebook.getAccessToken());
            parameters.putString("attachment", attachment.toString());
            String response = facebook.request("me/photos", parameters, "POST");
            System.out.println("----responce" + response);
            if (response.contains("Duplicate status message")) {
                progressHandler.sendEmptyMessage(1);
                resp = 1;
            } else if (response == null || response.equals("")
                    || response.equals("false") || response.contains("error")) {
                Log.d("error", "error response");
            } else {
                progressHandler.sendEmptyMessage(0);
                resp = 0;
            }
        } catch (Exception e) {
            Log.e(TAG, "Posting fail");
            e.printStackTrace();
            // finish();
        }
    }

我的应用程序支持facebook的单点登录。我不想使用对话框。每当我尝试在附件中同时发布图像和消息时，我都会捕获:

{"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}

查看文档中的图片POST请求https://developers.facebook.com/docs/reference/api/user/#photos

您的图像数据应该进入"source"字段，唯一可用的字段是"message"， "place "one_answers"no_story"。"src"， "name"， "href"是无效字段
