Streaming file from android to .net http service
Im trying to stream a file from android to an asp.net service:
private static void writeFile(File file, DataOutputStream out)
throws IOException {
BufferedInputStream bufferedFileIs = null;
Base64OutputStream base64out = null;
try {
out.writeBytes("fileBase64=");
base64out = new Base64OutputStream(out, Base64.DEFAULT);
FileInputStream fileIs = new FileInputStream(file);
bufferedFileIs = new Buffer开发者_JS百科edInputStream(fileIs);
int nextByte;
while ((nextByte = bufferedFileIs.read()) != -1) {
base64out.write(nextByte);
}
} finally {
if (bufferedFileIs != null) {
bufferedFileIs.close();
}
if(base64out != null)
base64out.flush();
}
}
and receive it like this
String base64 = Request.Form["fileBase64"];
byte[] bytes = System.Convert.FromBase64String(base64);
I use an HttpURLConnection and I dont get any exceptions but the received file(image) is corrupted in the process. I tried ALOT of different stream wrapper pairs, but no luck. Anyone have experience in this? I stream other form entries in the same connection and these arrive un-corrupted, for example
&UserID=12345
Gratefull for your help.
Cheers!
Solved it:
Prepare the file:
File file = new File(LocalFilePath);
FileEntity fileentity = new FileEntity(file, "UTF-8");
HttpUtilities.postRequest(WebServiceURL, fileentity);
post the request:
public static String postRequest(String url, HttpEntity aEntity)
throws IOException {
InputStream is = null;
try {
HttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httppost.setEntity(aEntity);
HttpResponse response = client.execute(httppost);
HttpEntity responseEntity = response.getEntity();
is = responseEntity.getContent();
} catch (Exception e) {
}
return getResponse(is);
}
after this the webserver complained:
HttpException (0x80004005): Maximum request length exceeded
max request-length defaults to 4mb so i set this in web.config:
<system.web>
<httpRuntime maxRequestLength="1048576"/>
</system.web
Which allows files up to 1GB(!).
edit:
Forgot the server code:
var str = Request.InputStream;
strLen = Convert.ToInt32(str.Length);
byte[] strArr = new byte[strLen];
strRead = str.Read(strArr, 0, strLen);
