上传图片HTTP POST的Andr​​oid

本文介绍了上传图片HTTP POST的Android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

我在Android和有问题的android上传影像新手。我已经试图找到例子，但有没有运气：

我有错误说：

和这里是我的code：我已经阵列名为图像它包含了我要上传图片的路径例如/storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg

// ONCLICK LISTENER公共OnClickListener upload_image =新OnClickListener（）{ @覆盖公共无效的onClick（视图v）{ // TODO自动生成方法存根如果（images.size（）！= 0）{ 。StrictMode.ThreadPolicy政策=新StrictMode.ThreadPolicy.Builder（）permitAll（）建（）; StrictMode.setThreadPolicy（政策）; 的for（int i = 0; I＆LT; images.size（）;我++）{ doFileUpload（images.get（I））; } } } };

// UPLOAD

难道我错过了财产以后？你能告诉什么是对我的code中的问题？

解决方案

公开文件上传（字符串URL，字符串userid，字符串文件路径，字符串状态）{ HttpClient的HttpClient的=新DefaultHttpClient（）; HttpPost httppost =新HttpPost（URL）; MultipartEntity实体=新MultipartEntity（ HttpMultipartMode.BROWSER_COMPATIBLE）; 的HttpParams的HttpParams = httpclient.getParams（）; httpParams.setIntParameter（CoreConnectionPNames.SO_TIMEOUT，100000）; 尝试{ entity.addPart（键1 新StringBody（用户ID，Charset.forName（UTF-8）））; entity.addPart（键2，新StringBody（状态，Charset.forName（UTF-8）））; entity.addPart（文件，新FileBody（新文件（文件路径）））; httppost.setEntity（实体）; ResponseHandler所＆LT;串GT; ResponseHandler所=新BasicResponseHandler（）; 字符串的响应= httpclient.execute（httppost，ResponseHandler所）; }赶上（例外五）{ } }

I'm newbie in android and having problem uploading image in android. I'd already tried to find examples but got no luck:

I am having error saying:

and here is my code: I have Array named "images" which contains the paths of images that I want to upload e.g. /storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg

//ONCLICK LISTENER public OnClickListener upload_image = new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if(images.size() != 0) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); for(int i=0; i<images.size(); i++){ doFileUpload(images.get(i)); } } } };

//UPLOAD

private void doFileUpload(String upload_file){ Log.d("Currently queued", upload_file); HttpURLConnection conn = null; DataOutputStream dos = null; DataInputStream inStream = null; String exsistingFileName = upload_file; // Is this the place are you doing something wrong. String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "acebdf13572468"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1*1024*1024; String urlString = "test.xponlm/MobileServices/api/ShipmentImages"; try { Log.e("MediaPlayer","Inside second Method"); FileInputStream fileInputStream = new FileInputStream(new File(exsistingFileName) ); URL url = new URL(urlString); conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); // Allow Outputs conn.setDoOutput(true); // Don't use a cached copy. conn.setUseCaches(false); // Use a post method. conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); dos = new DataOutputStream( conn.getOutputStream() ); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + exsistingFileName +"\"" + lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"ID\""+ lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(strshipmentID + lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"ImageType\""+ lineEnd); dos.writeBytes(lineEnd); dos.writeBytes("JPG" + lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"FileType\""+ lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(strtype + lineEnd); Log.e("MediaPlayer","Headers are written"); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) // tv.append(inputLine); Log.d("inputLine", inputLine); // close streams Log.e("MediaPlayer","File is written"); fileInputStream.close(); dos.flush(); dos.close(); } catch (MalformedURLException ex) { Log.e("MediaPlayer", "error1: " + ex.getMessage(), ex); } catch (IOException ioe) { Log.e("MediaPlayer", "error2: " + ioe.getMessage(), ioe); } //------------------ read the SERVER RESPONSE try { inStream = new DataInputStream ( conn.getInputStream() ); String str; while (( str = inStream.readLine()) != null) { Log.e("MediaPlayer","Server Response"+str); } /*while((str = inStream.readLine()) !=null ){ }*/ inStream.close(); } catch (IOException ioex){ Log.e("MediaPlayer", "error3: " + ioex.getMessage(), ioex); } }

Did I missed somthing? Can you tell what is the problem on my code?

解决方案

public Fileupload(String url, String userid, String filepath, String status) { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); MultipartEntity entity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE); HttpParams httpParams = httpclient.getParams(); httpParams.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 100000); try { entity.addPart("key 1", new StringBody(userid, Charset.forName("UTF-8"))); entity.addPart("key 2", new StringBody(status, Charset.forName("UTF-8"))); entity.addPart("File ", new FileBody(new File(filepath))); httppost.setEntity(entity); ResponseHandler<String> responseHandler = new BasicResponseHandler(); String response = httpclient.execute(httppost, responseHandler); } catch (Exception e) { } }
