问题描述
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
图片被张贴成功地
//打开一个URL连接到这个Servlet
的FileInputStream的FileInputStream =新的FileInputStream（的资源文件）;
网址URL =新的URL（http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/？）; //打开HTTP连接的URL
康恩=（HttpURLConnection类）url.openConnection（）;
conn.setDoInput（真）; //允许输入
conn.setDoOutput（真）; //允许输出
conn.setUseCaches（假）; //不要使用缓存副本
conn.setRequestMethod（POST）;
conn.setRequestProperty（连接，保持活动）;
conn.setRequestProperty（ENCTYPE，多部分/表单数据）;
conn.setRequestProperty（内容类型，的multipart / form-data的;边界=+边界）;
conn.setRequestProperty（POST_ID，1368）;
conn.setRequestProperty（USER_ID，62）;
conn.setRequestProperty（文件FILE_NAME）;
DOS =新的DataOutputStream类（conn.getOutputStream（））;
dos.writeBytes（twoHyphens +边界+ lineEnd）;
dos.writeBytes（内容处置：表格数据;名称=文件[];文件名=+ FILE_NAME ++ lineEnd）;
//dos.writeBytes(\"Content-Type：应用程序/八位字节流\\ r \\ n \\ r \\ n）;
//图像/ JPEG
dos.writeBytes（内容类型：image / JPEG \\ r \\ n \\ r \\ n）;
//创建最大大小的缓冲区
参考bytesAvailable = fileInputStream.available（）;
BUFFERSIZE = Math.min（方bytesAvailable，MAXBUFFERSIZE）;
缓冲区=新的字节[缓冲区大小]
//读取文件，并将其写入形式...
读取动作= fileInputStream.read（缓冲液，0，缓冲区大小）;
而（读取动作大于0）{
dos.write（缓冲液，0，缓冲区大小）;
参考bytesAvailable = fileInputStream.available（）;
BUFFERSIZE = Math.min（方bytesAvailable，MAXBUFFERSIZE）;
读取动作= fileInputStream.read（缓冲液，0，缓冲区大小）; } dos.writeBytes（lineEnd）;
dos.writeBytes（twoHyphens +边界+ twoHyphens + lineEnd）; //发送文件数据后necesssary多部分的表单数据... //服务器的响应（code和消息）
INT serverResponse code = conn.getResponse code（）;
serverResponseMessage = conn.getResponseMessage（）;
是= conn.getInputStream（）; Log.i（一个UploadFile，HTTP响应是：+ serverResponseMessage +：+ serverResponse code）; InputStreamReader的InputStreamReader的=新的InputStreamReader（是）;
的BufferedReader的BufferedReader =新的BufferedReader（InputStreamReader的）; 字符串bufferedStrChunk = NULL; 而（（bufferedStrChunk = bufferedReader.readLine（））！= NULL）{
stringBuilder.append（bufferedStrChunk）;
}
//关闭流//
fileInputStream.close（）;
dos.flush（）;
dos.close（）;
解决方案
有看这code为使用PHP服务器与其他数据上传图像的WebServices ...
code对于上传按钮...
上传=（按钮）findViewById（R.id.button1）;
upload.setOnClickListener（新View.OnClickListener（）{ 公共无效的onClick（视图v）{
位= BitmapFactory.de codeResource（getResources（），R.drawable.img）;
新ImageUploadTask（）执行（）;
}
}）;
这是异步任务上传图片与服务器的数据...
类ImageUploadTask扩展的AsyncTask＆LT;太虚，太虚，字符串＆GT; {
私人StringBuilder的S; @覆盖
在preExecute保护无效（）{
// TODO自动生成方法存根
super.on preExecute（）;
mProgress =新ProgressDialog（MainActivity.this）;
mProgress.setMessage（加载）;
mProgress.setProgressStyle（ProgressDialog.STYLE_SPINNER）;
mProgress.setCancelable（假）;
mProgress.show（）;
}
@覆盖
保护字符串doInBackground（虚空...... unsued）{
尝试{
串sResponse =;
字符串URL =http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/？
HttpClient的HttpClient的=新DefaultHttpClient（）;
HttpPost httpPost =新HttpPost（URL）;
MultipartEntity实体=新MultipartEntity（）; ByteArrayOutputStream BOS =新ByteArrayOutputStream（）;
bitmap.com preSS（比较pressFormat.JPEG，100，BOS）;
字节[]数据= bos.toByteArray（）;
entity.addPart（POST_ID，新StringBody（1368））;
entity.addPart（user_ID的新StringBody（62））;
entity.addPart（文件[]，新ByteArrayBody（数据，图像/ JPEG，test2.jpg））; httpPost.setEntity（实体）;
HTT presponse响应= httpClient.execute（httpPost）; 的BufferedReader读者=新的BufferedReader（新的InputStreamReader（response.getEntity（）的getContent（），UTF-8）。）; S =新的StringBuilder（）; 而（（sResponse = reader.readLine（））！= NULL）
{
S = s.append（sResponse）;
} 如果（response.getStatusLine（）的getStatus code（）== HttpStatus.SC_OK）
{
返回s.toString（）;
}其他
{
回归{\\状态\\：\\假\\，\\消息\\：\\出现了错误\\};
}
}赶上（例外五）{
Toast.makeText（getApplicationContext（），e.getMessage（），Toast.LENGTH_LONG）.show（）;
返回null;
}
} @覆盖
保护无效onPostExecute（字符串sResponse）{
尝试{
mProgress.dismiss（）;
如果（sResponse！= NULL）{
Toast.makeText（getApplicationContext（），sResponse +照片上传成功，Toast.LENGTH_SHORT）.show（）;
}
}赶上（例外五）{
Toast.makeText（getApplicationContext（），e.getMessage（），
Toast.LENGTH_LONG）.show（）;
Log.e（e.getClass（）的getName（），e.getMessage（），E。）;
}
}
}
添加权限中的Manifest.xml ..
＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;
Image is not able to reach on database
my doInBackground() method
try {
File file_name=new File("/storage/sdcard1/Received/IAF-Sarang.jpg");
DefaultHttpClient mHttpClient;
HttpParams par = new BasicHttpParams();
par.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
mHttpClient = new DefaultHttpClient(par);
try {
HttpPost httppost = new HttpPost("http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/?");
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("post_id", new StringBody("1368"));
multipartEntity.addPart("user_id", new StringBody("62"));
multipartEntity.addPart("files", new FileBody(file_name, "Content-Type: image/jpeg\r\n\r\n"));
httppost.setEntity(multipartEntity);
mHttpClient.execute(httppost, new PhotoUploadResponseHandler());
} catch (Exception e) {
e.printStackTrace();
System.out.println(""+e);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
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);
URL url = new URL("http://www.hugosys.in/www.nett-torg.no/api/rpcs/uploadfiles/?");
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
conn.setRequestProperty("post_id", "1368");
conn.setRequestProperty("user_id", "62");
conn.setRequestProperty("files", file_name);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data;name=files[];filename="+file_name+""+ lineEnd);
//dos.writeBytes("Content-Type: application/octet-stream\r\n\r\n");
// "image/jpeg"
dos.writeBytes("Content-Type: image/jpeg\r\n\r\n");
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
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);
// send multipart form data necesssary after file data...
// Responses from the server (code and message)
int serverResponseCode = conn.getResponseCode();
serverResponseMessage = conn.getResponseMessage();
is=conn.getInputStream();
Log.i("uploadFile", "HTTP Response is : "+ serverResponseMessage + ": " + serverResponseCode);
InputStreamReader inputStreamReader = new InputStreamReader(is);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String bufferedStrChunk = null;
while((bufferedStrChunk = bufferedReader.readLine()) != null){
stringBuilder.append(bufferedStrChunk);
}
//close the streams //
fileInputStream.close();
dos.flush();
dos.close();
解决方案
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"/>
