浏览数：64 / 时间：2015年06月11日

HTTP POST上传通用方法，支持文字、图片、文件等。

依赖jar包下载地址：http://hc.apache.org/downloads.cgi 下载HttpClient *** Binary。

将HttpComponents libraries中的httpmime-4.3.3.jar拷贝到Android工程的libs下即可。

//填充上传实体对象
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("String", new StringBody(“String”, Charset.forName("UTF-8")));
entity.addPart("File", new FileBody(new File(“path”)));

//调用post方法上传
HttpTools.post("url", entity)

//Http上传通用方法类
public class HttpTools {
    public static final int HTTP_SUCCESS = 200;
    private static String response_string = null;
    private static JSONObject response_json = null;

public static boolean post(String url, MultipartEntity entity) {

        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost(SERVER_ADDR + url);

            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost, localContext);

            if (response.getStatusLine().getStatusCode() == HTTP_SUCCESS) {

                response_string = EntityUtils.toString(response.getEntity());
                response_json = new JSONObject(response_string);
                
                return true;
            }
            
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        return false;

    }
