php - 使用多部分实体android在服务器上上传大文件

Question

您好，我正在使用多部分实体在服务器上上传文件，但它只在 php 服务器上上传小文件现在我想使用多部分实体上传大文件，我该怎么做？

-我正在从 sdcard 中获取大文件

public String uploadfile(String uploadFile, String crimedetails, String lat) 
{
    String url;
    MultipartEntity entity;
    try {
        url = String.format(WSConstants.SERVER_URL
                + WSConstants.URL_SET_POST);

        entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        //
        File file = new File(uploadFile);

        if (file.exists())
        {
            InputStream inputStream = null;
            ByteArrayOutputStream bos = null;
            try 
            {
                inputStream = new FileInputStream(file);
                bos = new ByteArrayOutputStream();
                //byte[] b = new byte[1 * 1024 * 1024];
                byte[] b = new byte[1024 * 8];
                int bytesRead = 0;

                while ((bytesRead = inputStream.read(b)) != -1)
                {
                    System.gc();
                    bos.write(b, 0, bytesRead);
                    bos.flush();
                }

            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }


            InputStream in = new ByteArrayInputStream(bos.toByteArray());
            ContentBody foto = new InputStreamBody(in, "application/pdf",uploadFile);

            entity.addPart("uploadfile", foto);
        }

        else {
            FormBodyPart image = new FormBodyPart("uploadfile",
                    new StringBody(""));
            entity.addPart(image);
        }

        FormBodyPart userId = new FormBodyPart("filename", new StringBody(
                String.valueOf(crimedetails)));
        entity.addPart(userId);

        FormBodyPart crimeType = new FormBodyPart("filetime",
                new StringBody(String.valueOf(lat)));
        entity.addPart(crimeType);

    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
        return "error";
    }

    HttpParams httpParams = new BasicHttpParams();

    HttpContext httpContext = new BasicHttpContext();
    HttpConnectionParams.setConnectionTimeout(httpParams, 10000);
    HttpConnectionParams.setSoTimeout(httpParams, 10000);

    String result = null;
    try {
        HttpPost httpPost = new HttpPost(url);
        httpPost.setEntity(entity);
        HttpClient client = new DefaultHttpClient();
        HttpResponse response = client.execute(httpPost);
        BufferedReader in = null;
        try {
            in = new BufferedReader(new InputStreamReader(response
                    .getEntity().getContent()));
            StringBuffer sb = new StringBuffer();
            String line = null;
            String NL = System.getProperty("line.separator");
            while ((line = in.readLine()) != null) {
                sb.append(line + NL);
            }

            result = sb.toString();
