图像无法达到数据库
我的doInBackground（）方法。
{尝试 文件文件名=新的文件（/存储/ sdcard1 /接收/ IAF-Sarang.jpg）; DefaultHttpClient mHttpClient; 比肩的HttpParams =新BasicHttpParams（）; par.setParameter（CoreProtocolPNames.PROTOCOL_VERSION，HttpVersion.HTTP_1_1）; mHttpClient =新DefaultHttpClient（PAR）; 尝试{ HttpPost httppost =新HttpPost（http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/？）; MultipartEntity multipartEntity =新MultipartEntity（HttpMultipartMode.BROWSER_COMPATIBLE）; multipartEntity.addPart（POST_ID，新StringBody（1368））; multipartEntity.addPart（user_ID的新StringBody（62））; multipartEntity.addPart（文件，新FileBody（FILE_NAME，内容类型：image / JPEG r n r n））; httppost.setEntity（multipartEntity）; mHttpClient.execute（httppost，新PhotoUploadResponseHandler（））; }赶上（例外五）{ e.printStackTrace（）; 的System.out.println（+ E）; } }赶上（例外五）{ // TODO自动生成catch块 e.printStackTrace（）; } 返回response_string; 下面是PhotoUploadResponseHandler类
私有类PhotoUploadResponseHandler实现ResponseHandler所＆LT;对象＆gt; { @覆盖 公共对象用handleResponse（HTT presponse响应） 抛出ClientProtocolException，IOException异常{ HttpEntity r_entity = response.getEntity（）; 字符串RSTRING = EntityUtils.toString（r_entity）; Log.d（UPLOAD，RSTRING）; response_string = RSTRING; 返回RSTRING; }} 有是无法触及code的一个多块，我已经试过，但在POST_ID

有看这code为使用PHP服务器与其他数据上传图像的WebServices ...

my doInBackground() method
try {

}
} catch (Exception e) {

}
return response_string;
Here is the PhotoUploadResponseHandler class
private class PhotoUploadResponseHandler implements ResponseHandler<Object> {
@Override
public Object handleResponse(HttpResponse response)
throws ClientProtocolException, IOException {
HttpEntity r_entity = response.getEntity();
String rString = EntityUtils.toString(r_entity);
Log.d("UPLOAD", rString);
response_string=rString;
return rString;
}
}
There is one more block of code which i have tried but in that post_id is not reached
Image was posted sucessfully
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);

Have look This code for uploading image with other data on server using php webservices...
Code For Upload Button...
upload = (Button) findViewById(R.id.button1);
upload.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
bitmap= BitmapFactory.decodeResource(getResources(), R.drawable.img);
new ImageUploadTask().execute();
}
});
This is async task to upload image with data on server...
class ImageUploadTask extends AsyncTask<Void, Void, String> {
private StringBuilder s;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
mProgress = new ProgressDialog(MainActivity.this);
mProgress.setMessage("Loading");
mProgress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
mProgress.setCancelable(false);
mProgress.show();
}
@Override
protected String doInBackground(Void... unsued) {
try {
String sResponse = "";
String url = "http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/?";
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
MultipartEntity entity = new MultipartEntity();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();
entity.addPart("post_id", new StringBody("1368"));
entity.addPart("user_id", new StringBody("62"));
entity.addPart("files[]", new ByteArrayBody(data,"image/jpeg", "test2.jpg"));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
s = new StringBuilder();
while ((sResponse = reader.readLine()) != null)
{
s = s.append(sResponse);
}
if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
{
return s.toString();
}else
{
return "{"status":"false","message":"Some error occurred"}";
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
return null;
}
}
@Override
protected void onPostExecute(String sResponse) {
try {
mProgress.dismiss();
if (sResponse != null) {
Toast.makeText(getApplicationContext(), sResponse + " Photo uploaded successfully",Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
}
Add Permission in Manifest.xml..
<uses-permission android:name="android.permission.INTERNET"/>
