张贴到服务器的单个图像局部 [英] Posting a Single image to server locally
本文介绍了张贴到服务器的单个图像局部的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想一个简单的图片上传到本地服务器
我所试图做的 ::我想一个图像上传到服务器上的按钮，点击
- 我已经提到此链接
- 但我不知道如何实施

解决方案
Use the below an try
public void postData() {
Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte [] ba = bao.toByteArray();
String ba1=Base64.encodeToString(ba,Base64.DEFAULT);
ArrayList<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",ba1));
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new
HttpPost("http://10.0.2.2:7002/Details/");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
}
Edit:
Just for testing try uploading image from sdcard using file path
try
{
String filepath= Environment.getExternalStorageDirectory().getAbsolutePath()+File.separator+"Download"+File.separator+"ic_launcher.png";
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost("your url");
File file = new File(filepath);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String _response=EntityUtils.toString(entity);
Log.i(".......",_response);
}catch(Exception e){
e.printStacktrace();
}
