以编程方式在 Android 中的 Php 服务器上上传图像
Upload Image On Php Server In Android Programically
我正在尝试将图像从 android 上传到 php 服务器 服务器正在使用 objective c 为 ios 正常工作,但在 android 我不知道怎么上传图片。我已经尝试了下面的代码,但是服务器 returns 消息说(图像格式不正确或缺少图像文件
ArrayList<File> imageFiles= new ArrayList<File>();
for(int i=0;i<mCameraDataList.size();i++) {
File f = new File(getFilesDir(),"image"+i+".jpg");
f.createNewFile();
Bitmap bitmap = Bitmap.createScaledBitmap(
BitmapFactory.decodeByteArray(mCameraDataList.get(i), 0, mCameraDataList.get(i).length),CommonMethods.getDeviceWidth(this), CommonMethods.getDeviceHeight(this), true);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream);
byte[] bitmapdata = stream.toByteArray();
FileOutputStream fos = new FileOutputStream(f);
fos.write(bitmapdata);
fos.flush();
fos.close();
imageFiles.add(f);
}
public static void postProduct(ArrayList<File> nImages) throws UnsupportedEncodingException {
MultipartEntityBuilder entity=MultipartEntityBuilder.create();
entity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("authenticity",new StringBody("1"));
entity.addPart("brand_id",new StringBody("1"));

entity.addPart(Constants.KeyValues.UID,new StringBody(String.valueOf(CommonObjects.getUserProfile().getUid())));
for(int i=0;i<nImages.size();i++)
{
File f=new File(nImages.get(i).getAbsolutePath());
if(f.exists()){
entity.addPart(Constants.KeyValues.IMAGES, new FileBody(f, "image/jpeg"));
}
}
new SetDataToServer(Constants.NetworkServiceMethods.Product.POST_PRODUCT, entity, new SetDataToServer.SetDataNotifier() {
@Override
public void onDataReceived(boolean isError, String message, JSONObject jsonObj) {
ArrayList<String> postProductResult =new ArrayList<String>();
try {
Log.e("JSON",jsonObj.toString());
if (!jsonObj.isNull(Constants.KeyValues.DATA)) {
JSONObject jsonObjectData = jsonObj.getJSONObject(Constants.KeyValues.DATA);
// postProductResult.add(jsonObjectData.getString(Constants.KeyValues.CON_ID));
// postProductResult.add(jsonObjectData.getString(Constants.KeyValues.ORDER_ID));
}
} catch (JSONException e) {
isError = true;
message = "Sorry! Error occurred in data parsing";
}
productHandlerMethods.onPostProductResult(isError, message, postProductResult);
}
}).callServerToSetData();
}
任何人都可以告诉我做错了什么。

尝试通过android中编写的以下服务上传图片,确保下面代码中的图片路径正确,将图片放在sdcard中:
