java - Android - 如何上传视频/图像到 PHP 服务器

Question

我可以使用以下代码将字符串值发布到 PHP 服务器:

 public void callWebService(String strEmailList){
    HttpResponse response = null;
    String responseBody="";
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
    nameValuePairs.add(new BasicNameValuePair("stringkey1",
            String_Value1));
    nameValuePairs.add(new BasicNameValuePair("stringkey2", String_Value2));
    nameValuePairs.add(new BasicNameValuePair("stringkey3", String_Value3));
    nameValuePairs.add(new BasicNameValuePair("stringkey4", String_Value4));
    nameValuePairs.add(new BasicNameValuePair("stringkey5", String_Value5));
    nameValuePairs.add(new BasicNameValuePair("stringkey6", Here i need to post Image));

    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://MY URL");

        if (nameValuePairs != null)
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        response = httpclient.execute(httppost);
        responseBody = EntityUtils.toString(response.getEntity());
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    handleResponse(responseBody);
}

如果我仅发布字符串值，我将完美地获得 responseBody 。在 nameValuePair 中，我需要将图像发布到服务器。谁能帮助我如何使用以下代码发布图像。

您可以将图像作为多部分实体发送到服务器

public void upload(String filepath) throws IOException
    {
     HttpClient httpclient = new DefaultHttpClient();
     httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
     HttpPost httppost = new HttpPost("url");
     File file = new File(filepath);
     MultipartEntity mpEntity = new MultipartEntity();
     ContentBody cbFile = new FileBody(file, "image/jpeg");
     mpEntity.addPart("userfile", cbFile); 
     httppost.setEntity(mpEntity);
     System.out.println("executing request " + httppost.getRequestLine());
     HttpResponse response = httpclient.execute(httppost);
     HttpEntity resEntity = response.getEntity();
             // check the response and do what is required
      }
