求解决一个利用HttpClient4用post连接服务器的问题，已经可以读服务器，服务器却不能收到post参数

[templefox]

	private void multifunctionalConnect(final String url,
			final Map<String, String> keyValuePair,
			final Map<String, Bitmap> keyFilePair, final MessageHandler handler)
			throws ClientProtocolException, IOException {
		// Create client with parameters, to control timeout or else.
		HttpParams param = new BasicHttpParams();
		HttpConnectionParams.setConnectionTimeout(param, TIME_OUT);
		HttpConnectionParams.setSoTimeout(param, TIME_OUT);
		HttpClient client = new DefaultHttpClient(param);

		// Create request with parameters.
		HttpPost request = new HttpPost(url);
		request.addHeader(HTTP.CHARSET_PARAM, HTTP.UTF_8);

		// 1.Create multipart entity.
		MultipartEntityBuilder entity = MultipartEntityBuilder.create();
		entity.setCharset(Charset.forName(HTTP.UTF_8));
		//entity.setBoundary("******");
		//entity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
		// 2.Add text body.
		if (keyValuePair != null && !keyValuePair.isEmpty()) {
			for (String key : keyValuePair.keySet()) {
				entity.addTextBody(key, keyValuePair.get(key),ContentType.TEXT_PLAIN);
				
			}
		}
		// 3.Add binary body.
		if (keyFilePair != null && !keyFilePair.isEmpty()) {
			for (String name : keyFilePair.keySet()) {
				Bitmap bitmap = keyFilePair.get(name);
				File tempFile = File.createTempFile(name, ".jpeg");
				FileOutputStream outputStream = new FileOutputStream(tempFile);
				bitmap.compress(CompressFormat.JPEG, 100, outputStream);
				outputStream.flush();
				outputStream.close();

				FileInputStream inputStream = new FileInputStream(tempFile);

				entity.addBinaryBody(name, inputStream);
				
			}
		}
		// 4.Set Entity
		request.setEntity(entity.build());

		// 5.Execute and get response
		HttpResponse response = client.execute(request);
		String json = null;
		if (HttpStatus.SC_OK == response.getStatusLine().getStatusCode()) {
			BufferedReader reader = new BufferedReader(new InputStreamReader(
					response.getEntity().getContent()));
			StringBuilder sb = new StringBuilder();
			for (String s = reader.readLine(); s != null && s.length() != 1
					&& !s.isEmpty(); s = reader.readLine()) {
				String ss = s.substring(1);
				sb.append(ss);
			}

			json = sb.toString();

		}

我使用php服务器 比如post参数中有键值mkey:mvalue
php的取法为$_POST['mkey'],然后echo出来，但读出来的结果都是空，求教。
而正常的读如 echo "hello world";测试可以。

之前我用了另一个实体UrlEncodedFormEntity能实现。
不知是不是如今的MultipartEntity的问题

[templefox]

测试了很久仍然不知道问题出在哪里 我直接用httpUrlConnection的OutPutStream把上述entity写入发现是可以用$_POST取得 DataOutputStream dos = new DataOutputStream(httpURLConnection.getOutputStream()); entity.build().writeTo(dos); 所以现在MultipartEntity配合httpUrlConnection是OK的 然后HttpClient配合UrlEncodedFormEntity也ok 但是两个前者就不ok！！
