您好，我正在发送图像和文本到php webservice使用以下代码。如何发送多个图像到服务器使用MultipartEntity从android
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(URL);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
entity.addPart("files[]",
new ByteArrayBody(data, "myImage.jpg"));
entity.addPart("message0", new StringBody(caption.getText()
.toString()));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse = reader.readLine();
return sResponse;
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Toast.makeText(ImageUpload.this, e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
return null;
}
}
它工作完美。但这仅适用于一个图像发送。现在我发送5个图像和文字。
例子： - 图像1 - 文本1
镜像2 - 文本2等。
所以我混淆如何逐一在最终提交点击发送与之相关的服务器的图像和文字来存储5个图像。
我只从相机中获取图像。
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE);
public void onActivityResult_photo(int requestCode, int resultCode,
Intent data) {
// TODO Auto-generated method stub
if (resultCode == RESULT_OK) {
if (data != null) {
mImageCaptureUri = data.getData();
display(mImageCaptureUri);
} else {
Toast.makeText(CustomTabActivity.mTabHost.getContext(),
"No photo selected..", Toast.LENGTH_SHORT).show();
}
}
}
private String display(Uri mImageCaptureUri2) {
// TODO Auto-generated method stub
String base64string = null;
try {
if (mImageCaptureUri2 != null) {
System.gc();
selectedImagePath = getPath(mImageCaptureUri2);
File filenew = new File(selectedImagePath);
int file_size = Integer.parseInt(String.valueOf(filenew
.length()/1024));
if (file_size <= 10000) {
PD1 = ProgressDialog.show(
CustomTabActivity.mTabHost.getContext(), "",
"Loading...");
Handler refresh = new Handler(Looper.getMainLooper());
refresh.post(new Runnable() {
public void run() {
PD1.setCancelable(true);
Bitmap newbitmap;
newbitmap = decodeFile(selectedImagePath);
ByteArrayOutputStream bs = new ByteArrayOutputStream();
newbitmap.compress(Bitmap.CompressFormat.PNG, 50,
bs);
img.setVisibility(View.VISIBLE);
img.setImageBitmap(newbitmap);
byte[] abc = bitmapToByteArray(newbitmap);
if (txt_phototext.getText().toString().equals("")) {
submit.put(abc, "");
} else {
submit.put(abc, txt_phototext.getText()
.toString());
// executeMultipartPost();
}
PD1.dismiss();
}
});
} else {
AlertDialog.Builder alertbox = new AlertDialog.Builder(
CustomTabActivity.mTabHost.getContext());
alertbox.setMessage("Take Image Size Less than 10 MB");
alertbox.setNeutralButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0,
int arg1) {
finish();
}
});
alertbox.show();
}
} else {
System.out.println("===============NULL========");
}
} catch (Exception e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
}
return base64string;
}
static Bitmap decodeFile(String str) {
try {
// decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(str), null, o);
// Find the correct scale value. It should be the power of 2.
final int REQUIRED_SIZE = 70;
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp/2 < REQUIRED_SIZE
|| height_tmp/2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale++;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(str), null,
o2);
} catch (FileNotFoundException e) {
}
return null;
}
public static byte[] bitmapToByteArray(Bitmap bitmap) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos);
byte[] bitmapdata = bos.toByteArray();
return bitmapdata;
}
所以最后我坚持这个请大家帮忙。
