Android DefaultHttpClient 上传文件

需要依赖httpmime.jar

public class HttpText {public static void UseVolleyForHttps(Context context) {try {String path = "http://192.168.0.102:8080/myweb/der";BasicHttpParams params = new BasicHttpParams();HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);HttpProtocolParams.setContentCharset(params,HTTP.DEFAULT_CONTENT_CHARSET);HttpProtocolParams.setUseExpectContinue(params, true);SSLSocketFactory.getSocketFactory().setHostnameVerifier(new AllowAllHostnameVerifier());SchemeRegistry schReg = new SchemeRegistry();schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));// 出错：因为使用了不被系统承认的自定义证书：No peer certificate 。// schReg.register(new// Scheme("https",SSLSocketFactory.getSocketFactory(), 443));schReg.register(new Scheme("https", SSLTrustAllSocketFactory.getSocketFactory(), 443));ClientConnectionManager connMgr = new ThreadSafeClientConnManager(params, schReg);DefaultHttpClient client = new DefaultHttpClient(connMgr, params);org.apache.http.entity.mime.MultipartEntity s = new org.apache.http.entity.mime.MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);// 测试文件File file = new File(context.getCacheDir(), "jt.txt");if (!file.exists()) {file.createNewFile();}FileWriter w = new FileWriter(file);w.write("橘子面包");w.flush();s.addPart(new FormBodyPart("title", new StringBody("juntao")));s.addPart("file", new FileBody(file, "text/plain"));HttpPost post = new HttpPost(path);post.setEntity(s);HttpResponse httpResponse = client.execute(post);int responseCode = httpResponse.getStatusLine().getStatusCode();String message = httpResponse.getStatusLine().getReasonPhrase();HttpEntity entity = httpResponse.getEntity();if(responseCode==200){Log.e("成功", "succee");}} catch (ClientProtocolException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

服务器端：
