Приведенный ниже код прекрасно работает, если я подключаюсь к серверам Apache, однако при попытке подключиться к моему.Net-серверу выдает ошибку. Я предполагаю, что это требование заголовка, но я не могу получить успешный ответ, что бы я ни пытался.
public String Download(String Url)
{
String filepath=null;
try {
//set the download URL, a url that points to a file on the internet
//this is the file to be downloaded
URL url = new URL(Url);
//create the new connection
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//set up some things on the connection
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
//and connect!
urlConnection.connect();
//set the path where we want to save the file
//in this case, going to save it on the root directory of the sd card.
File SDCardRoot = Environment.getExternalStorageDirectory();
//create a new file, specifying the path, and the filename
//which we want to save the file as.
String filename= "effortback.png"; // you can download to any type of file ex:.jpeg (image) ,.txt(text file),.mp3 (audio file)
Log.i("Local filename:",""+filename);
File file = new File(SDCardRoot + "/",filename);
//=====================================
if(file.createNewFile())
{
file.createNewFile();
}
//=====================================
//this will be used to write the downloaded data into the file we created
FileOutputStream fileOutput = new FileOutputStream(file);
//this will be used in reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
//=====================================
//this is the total size of the file
int totalSize = urlConnection.getContentLength();
//variable to store total downloaded bytes
int downloadedSize = 0;
//=====================================
//create a buffer...
byte[] buffer = new byte[2048];
int bufferLength = 0; //used to store a temporary size of the buffer
//now, read through the input buffer and write the contents to the file
while ( (bufferLength = inputStream.read(buffer)) > 0 ) {
//add the data in the buffer to the file in the file output stream (the file on the sd card
fileOutput.write(buffer, 0, bufferLength);
//add up the size so we know how much is downloaded
downloadedSize += bufferLength;
//this is where you would do something to report the prgress, like this maybe
Log.i("Progress:","downloadedSize:"+downloadedSize+"totalSize:"+ totalSize) ;
}
//close the output stream when done
fileOutput.close();
if(downloadedSize==totalSize) filepath=file.getPath();
//catch some possible errors...
} catch (MalformedURLException e) {
e.printStackTrace();
Log.i("URL-ERROR:",e.toString());
} catch (IOException e) {
filepath=null;
e.printStackTrace();
Log.i("IO-ERROR:",e.toString());
}
Log.i("filepath:"," "+filepath) ;
return filepath;
}
Ошибки варьируются от:
java.io.FileNotFoundException //I always get this with either one of the below
org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1061)
//or this one below
libcore.net.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionTmpl.java:186)
Кажется, что независимо от того, что я пытаюсь, я не могу заставить его работать. Опять же, это работает, если я пытаюсь загрузить изображение с Google или некоторых других сайтов, но не со всех, но определенно не с моего (.Net). Что мне здесь не хватает? Пожалуйста помоги.
