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();

// TODO Auto-generated catch block
e.printStackTrace();

关于上传文字乱码的情况说明:
之前没有设置文字编码
entity.addPart("String", new StringBody(“String”));
直接上传文字就会乱码。
在Android开发中,以HttpPost方式向服务器上提交中文数据时,如果没有设置传输数据的编码类型,在服务端获取到的数据就会出现乱码。在涉及不同平台上的应用,我们尽量使用UTF-8编码格式传输中文数据,HttpPost方式传输中文指定编码可以参考以下方法:
entity.addPart("String", new StringBody(“String”,
Charset.forName("UTF-8")));
