Java 使用HttpClient发布Base64编码的视频文件

Java 使用HttpClient发布Base64编码的视频文件,java,httpclient,apache-commons,Java,Httpclient,Apache Commons,我正在尝试使用HttpClient将媒体文件发布到服务器。我的代码适用于图像文件,但是视频文件(mp4)无法重放。我发布文件的代码: HttpClient httpclient = new DefaultHttpClient(); httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); HttpPost httppost = new Ht

我正在尝试使用HttpClient将媒体文件发布到服务器。我的代码适用于图像文件,但是视频文件(mp4)无法重放。我发布文件的代码:

   HttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

    HttpPost httppost = new HttpPost(REMOTE + "/add_file.php");

    MultipartEntityBuilder mpEntity = MultipartEntityBuilder.create();
    ContentBody cbFile = null;
    String mimeType = "";
    if (file.getName().endsWith(".jpg") || file.getName().endsWith(".jpeg")) {
        mimeType = "image/jpeg";
    } else if (file.getName().endsWith(".mp4")) {
         mimeType = "video/mp4";
    }


    mpEntity.addTextBody("recipient_phone", recipientPhoneStr);
    mpEntity.addTextBody("sender_phone", "55000");
    mpEntity.addTextBody("sender_key", "my_secret");
    mpEntity.addTextBody("file_name", file.getName());

    mpEntity.addTextBody("userfile", encodeFileToBase64Binary(file));

    httppost.setEntity(mpEntity.build());

    HttpResponse response = httpclient.execute(httppost);
    HttpEntity resEntity = response.getEntity();


    if (response.getStatusLine().toString().compareTo(HTTP_ERROR) == 0) {
        throw new IOException(HTTP_ERROR);
    }

    if (resEntity != null) {
        System.out.println(EntityUtils.toString(resEntity));
    }
    if (resEntity != null) {
        resEntity.consumeContent();
    }

    httpclient.getConnectionManager().shutdown();
使用Base64.encodeBase64String(字节)对文件进行Base64编码

查看示例POST程序

使用以下命令将mp4映射到字节,然后将其包装为适当的“实体”类型,以便执行POST

            FileInputStream fis = new FileInputStream(mfile); 
            FileChannel fc = fis.getChannel(); // Get the file's size and then map it into memory
            int sz = (int)fc.size();
            MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, sz);
            byte[] data2 = new byte[bb.remaining()];
            bb.get(data2);
            ByteArrayEntityHC4 reqEntity = new ByteArrayEntityHC4(data2);
            httpPost.setEntity(reqEntity);
            fis.close();

然后根据POST类型的请求调用exec。

您是否已检查是否正确接收了所有字节?您可能达到了php的post_max_大小或apache/nginx限制。谢谢bart。是的,post_max_大小足够了…如何检查apache限制?将文件映射到字节,并将缓冲区包装在post的“byteArrayEntity”中。这是发送视频文件(mp4,mov)的一个很好的解决方案。其他解决方案仅适用于pdf/ppt/text等,但不适用于mp4。
