如何以 JSON 格式上传视频和其他参数

Question

我想执行一个发布请求。我的 POST 数据将有几个字符串参数以及视频数据。如何做到这一点？ 上传视频以及字符串、数组、NSDictionary 值等其他参数的最佳方式是什么？

Answer 1

您通常会使用 HTTP MultiPart Mime POST 请求消息来执行此操作 - 该消息可以包含视频和您想要包含的任何参数。

根据您的标签，我猜您想在 iOS 中执行此操作 - 如果是这样，此答案提供了一个完整示例：https://stackoverflow.com/a/24252378/334402

如果您想在 Android 中执行此操作，则可以使用以下方法（请参阅添加的标题和描述参数）：

        //Create a new Multipart HTTP request to upload the video
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(serverURL);

        //Create a Multipart entity and add the parts to it
        try {
            Log.d("VideoUploadTask doInBackground","Building the request for file: " + videoPath);
            FileBody filebodyVideo = new FileBody(new File(videoPath));
            StringBody title = new StringBody("Filename:" + videoPath);
            StringBody description = new StringBody("Test Video");
            MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            reqEntity.addPart("videoFile", filebodyVideo);
            reqEntity.addPart("title", title);
            reqEntity.addPart("description", description);
            httppost.setEntity(reqEntity);
        } catch (UnsupportedEncodingException e1) {
            //Log the error
            Log.d("VideoUploadTask doInBackground","UnsupportedEncodingException error when setting StringBody for title or description");
            e1.printStackTrace();
            return -1;
        }

        //Send the request to the server
        HttpResponse serverResponse = null;
        try {
            Log.d("VideoUploadTask doInBackground","Sending the Request");
            serverResponse = httpclient.execute( httppost );
        } catch (ClientProtocolException e) {
            //Log the error
            Log.d("VideoUploadTask doInBackground","ClientProtocolException");
            e.printStackTrace();
        } catch (IOException e) {
            //Log the error
            Log.d("VideoUploadTask doInBackground","IOException");
            e.printStackTrace();
        }
