Question

我一直试图通过java程序调用视频智能的其余API来注释本地文件。这是我的代码：

        byte[] data = Files.readAllBytes(path);
        byte[] encodedBytes = Base64.encodeBase64(data);

        URIBuilder builder = new URIBuilder("https://videointelligence.googleapis.com/v1beta2/videos:annotate");
        URI uri = builder.build();
        HttpPost request = new HttpPost(uri);
        request.setHeader("Content-Type", "application/json");
        request.setHeader("X-Goog-Api-Key",MyKey);

        JSONObject json = new JSONObject();
        JSONArray jsonArray = new JSONArray();
        jsonArray.put("LABEL_DETECTION");
        json.put("inputContent", encodedBytes);
        json.put("features", jsonArray);

        StringEntity reqEntity = new StringEntity(json.toString());
        request.setEntity(reqEntity);
        HttpResponse response = httpclient.execute(request);
        HttpEntity entity = response.getEntity();

我收到此错误：＆＃34;错误＆＃34;：{ ＆＃34;代码＆＃34;：400，＆＃34; message＆＃34;：＆＃34;收到无效的JSON有效负载。未知名称\＆＃34; input_content \＆＃34 ;: Proto字段不重复，无法启动列表。

有人可以帮我解决这个错误吗？谢谢

错误消息实际上没有帮助。这里的问题是“inputContent”应该是String而不是byte[]。这对我有用：

String str = new String(encodedBytes, "UTF-8");
requestJson.put("inputContent", str);

在JAVA中调用其余的视频智能API
