android - 生成 httprequest 以从 android 镜像 api 服务的正确方法

Question

我尝试从我的 Android 应用程序将时间线卡推送到 Glass。我使用这段代码:

String BASE_URL = "https://www.googleapis.com/upload/mirror/v1/";

    try {
        final HttpPost request = new HttpPost();
        request.setURI(new URI(BASE_URL + "timeline"));
        request.addHeader("Authorization", String.format("Bearer %s", token));
        request.addHeader("Content-Type", "application/json");
        request.setEntity(new StringEntity(json.toString()));

        // Execute the request on a background thread
        mThreadPool.execute(new Runnable() {
            @Override
            public void run() {
                try {
                    final HttpResponse response = mClient.execute(request);
                    if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                        mHandler.post(new Runnable() {
                            @Override
                            public void run() {
                                callback.onSuccess(response);
                            }
                        });
                    } else {
                        mHandler.post(new Runnable() {
                            @Override
                            public void run() {
                                callback.onFailure(response, null);
                            }
                        });
                    }
                } catch (final IOException e) {
                    mHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            callback.onFailure(null, e);
                        }
                    });
                }
            }
        });
    } catch (UnsupportedEncodingException e) {
        // Note: This should never happen
    } catch (URISyntaxException e) {
        // Note: This should never happen
    }

json 是这样的:

{"notification":{"level":"DEFAULT"},"text":"Pizza and spaghetti"}

但服务响应错误:

"error": {
"errors": [
{
"domain": "global",
"reason": "badContent",
"message": "Media type 'application/json' is not supported. Valid media types: [image/*, audio/*, video/*]"
}
],
"code": 400,
"message": "Media type 'application/json' is not supported. Valid media types: [image/*, audio/*, video/*]"
}
}

我遵循这里的代码:https://github.com/twaddington/mirror-quickstart-android

有什么想法吗？

附言。还有另一种方法可以将时间线卡从安卓应用程序推送到谷歌眼镜吗？

谢谢

如您在 Google 文档 (https://developers.google.com/glass/v1/reference/timeline/insert) 中所见，此请求仅接受多媒体数据作为“内容类型”。

尝试使用正确的内容类型(图像/、音频/、视频/*)更改此行 :request.addHeader("Content-Type", "application/json") ;


您必须在 HTTPost 对象中添加多媒体对象。更多信息: Sending images using Http Post

--编辑--您想要执行的请求(只有元数据，没有多媒体)必须完成: https://www.googleapis.com/mirror/v1/ (注意这里没有上传字样)。
