I'm trying to serve an image using akka-http, but keep getting error in the browser about MIME type:
Resource interpreted as Document but transferred with MIME type image/png: "http://localhost/banners/ci.png".
That's the server-side code:
pathPrefix("banners"){
get {
entity(as[HttpRequest]) { requestData =>
complete {
val fullPath = requestData.uri.path.toString match {
case _ => Paths.get(workingDirectory + requestData.uri.path.toString)
}
val contentType = getExtensions(fullPath.toString) match {
case "jpg" => ContentType(MediaTypes.`image/jpeg`)
case "png" => ContentType(MediaTypes.`image/png`)
case "html" => ContentTypes.`text/html(UTF-8)`
}
val h = RawHeader("Access-Control-Allow-Origin","*")
val byteArray = Files.readAllBytes(fullPath)
HttpResponse(OK, entity = HttpEntity(contentType,byteArray)).withHeaders(h)
}
}
}
} ~
Here is the response headers copied from chrome developer console:
HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Server: akka-http/10.0.7
Date: Fri, 26 May 2017 13:08:04 GMT
Content-Type: image/png
Content-Length: 581
Any ideas how can I fix it ?

I'm trying to get a self-hosted Nancy app running, but I'm having trouble getting it to return valid responses. I'm new at Nancy; I expect my problem is something fairly simple.
Here's some code:
class Program
{
static void Main(string[] args)
{
const String PORT_SETTING = "webServicePortNumber";
const String URI = "http://localhost:{0}/download/";
var portNum = ConfigurationManager.AppSettings[PORT_SETTING];
var uri = new Uri(String.Format(URI, portNum));
var config = new HostConfiguration {
UrlReservations = new UrlReservations { CreateAutomatically = true }
};
using (var nancyHost = new NancyHost(new Bootstrapper(), config, uri)) {
nancyHost.Start();
Console.WriteLine(String.Format("Listening on {0}. Press any key to stop.", uri.AbsoluteUri));
Console.ReadKey();
}
Console.WriteLine("Stopped. Press any key to exit.");
Console.ReadKey();
}
}
internal class Bootstrapper : DefaultNancyBootstrapper
{
protected override Nancy.Diagnostics.DiagnosticsConfiguration DiagnosticsConfiguration
{
get {
return new DiagnosticsConfiguration {
Password = #"[password]"
};
}
}
}
My NancyModule looks like this:
public class DownloadsModule : NancyModule
{
public DownloadsModule() : base("/download")
{
RegisterRoutes();
}
private void RegisterRoutes()
{
Put["/"] = parms => InitiateDownload(parms);
Get["/"] = parms => Summary(parms);
Get["/{id}"] = parms => GetStatus(parms.requestId);
}
private Response GetStatus(Guid requestId)
{
return Response.AsText("TEST: GetStatus requestId " + requestId);
}
private Response Summary(dynamic parms)
{
return Response.AsText("Summary: You loved me before, do you love me now?");
}
private Response InitiateDownload(dynamic parms)
{
return Response.AsText("InitiateDownload.");
}
}
Nancy is running; I can access the diagnostics at http://127.0.0.1:8880/download/_Nancy/. Looking at them, the routes appear ready. Interactive Diagnostics/GetAllRoutes shows:
P U T
name: [nothing] path: /download
G E T
name: [nothing] path: /download
name: [nothing] path: /download/{id}
And yet, I'm getting 404s back when I try http://localhost:8880/download/.
The request trace on the diagnostics page shows:
Method: GET
Request Url:
Scheme: http
Host Name: localhost
Port: 8880
Base Path: /download
Path: /
Query:
Site Base: http://localhost:8880
Is Secure: false
Request Content Type:
Response Content Type: text/html
Request Headers:
<snip>
Accept: text/html;q=1
application/xhtml+xml;q=1
image/webp;q=1
application/xml;q=0.9
*/*;q=0.8
<snip>
Response Headers:
Status Code: 404
Log: New Request Started
[DefaultResponseNegotiator] Processing as real response
So why isn't Nancy routing this request to the proper route?
Problem pointed out to me by jchannon in the Nancy JabbR room:
The URI specifies http://localhost:{0}/download/, while the module also specifies a base path of /download, so currently its looking for an URL of http://localhost:{0}/download/download/
I want to send a file from my server side (EJB) using REST Jersey (JAX-RS).
I am trying with the following code,
Public Response getFiles() {
File file = new File(fileName);
FileOutputStream dest = new FileOutputStream(file);
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(dest));
out.putNextEntry(new ZipEntry(fileName));
final ResponseBuilder response = Response.ok(out);
response.header("Content-Type", "*/*");
response.header("Content-Disposition", "attachment; filename=" + file.getName() + ".zip");
return response.build();
}
But I am getting the exception message
type class java.util.zip.ZipOutputStream, and MIME media type */* was not found
SEVERE: The registered message body writers compatible with the MIME media type are:
Also tried with "Content-Type" , "application/octet-stream", "application/x-www-form-urlencoded" and multipart/form-data
But none of them is working.
Use application/zip.
#GET
#Produces("application/zip")
public Response getZip() {
final File f = new File("/tmp/foo.zip");
ResponseBuilder response = Response.ok((Object) f);
response.header("Content-Disposition", "attachment; filename=" + f.getName());
return response.build();
}
application/octet-stream + gzip
#GET
#Path("/getFiles")
#Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response getFiles() {
StreamingOutput stream = new StreamingOutput() {
#Override
public void write(OutputStream output) throws IOException, WebApplicationException {
String filePath = "/yourFile.pdf";
java.nio.file.Path path = Paths.get(filePath);
byte[] data = Files.readAllBytes(path);
output.write(data);
output.flush();
}
};
return Response.ok(stream).build();
}
and a jersey filter added to web.xml
<init-param>
<param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
<param-value>com.sun.jersey.api.container.filter.GZIPContentEncodingFilter</param-value>
</init-param>
when making the request:
send a header of "Accept" with value of "application/octet-stream"
and a header of "Accept-Encoding" with value of "gzip"
I'm trying to upload whole folder to google drive.
I could successfully upload one file by one request.
But I met rateLimitExceed error while upload whole files.
So, I tried to use batch request.
Creating folders with batch request are successfully done.
but when I trying to upload file by batch request, it returns 404 error. ( Not Found )
Is this google drive's bug?
If so, should I do time delay for upload many files?

I would like to ADD a ACL to a Google Storage object using the Json API from appengine. I have tried the following code, however I get a 400 response with no details. I am not using the java-client-libraries, however I am willing to try. Below is my code:
public static void updateACL(String bucket, String object,
List<String> emails) {
try {
ArrayList scopes = new ArrayList();
scopes.add("https://www.googleapis.com/auth/devstorage.full_control");
AppIdentityService appIdentity = AppIdentityServiceFactory
.getAppIdentityService();
AppIdentityService.GetAccessTokenResult accessToken = appIdentity
.getAccessToken(scopes);
// The token asserts the identity reported by
// appIdentity.getServiceAccountName()
logger.log(Level.WARNING, "bucket: "+bucket+" object: "+object+ " email: "+emails.get(0));
JSONObject request = new JSONObject();
request.put("entity", "user-" + emails.get(0));
request.put("roles", "READER");
URL url = new URL("https://www.googleapis.com/storage/v1beta1/b/"
+ bucket + "/o/"+object+"/acl?key=" + API_KEY);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.addRequestProperty("Content-Type", "application/json");
connection.addRequestProperty("Authorization", "OAuth "
+ accessToken.getAccessToken());
String urlParameters = "bucket=" + bucket + "&object=" + object;
OutputStreamWriter writer = new OutputStreamWriter(
connection.getOutputStream());
request.write(writer);
writer.close();
logger.log(Level.WARNING, connection.getResponseMessage());
logger.log(Level.WARNING,
String.valueOf(connection.getResponseCode()));
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
// Note: Should check the content-encoding.
// JSONTokener response_tokens = new
// JSONTokener(connection.getInputStream());
// JSONObject response = new JSONObject(response_tokens);
// return (String) response.get("id");
return;
} else {
Scanner s;
s = new Scanner(connection.getErrorStream());
s.useDelimiter("\\Z");
String response = s.next();
s.close();
throw new Exception(connection.getResponseCode()+" "+connection.getResponseMessage()+
response);
}
} catch (Exception e) {
logger.log(Level.WARNING, "exception: "+e.getMessage());
}
}
The response I get is a 400, but the details are not helpful at all.
"error": {
"errors": [
{
"domain": "global",
"reason": "required",
"message": "Required"
}
],
"code": 400,
"message": "Required"
}
}
I suspect there's a tiny bug or two in your code. In this particular instance it looks like you are sending roles when the JSON api expects role.
One thing I find helpful for debugging is to compare what my code is sending over the wire with the HTTP request the Google APIs explorer generates.
Navigate to https://developers.google.com/storage/docs/json_api/v1/objectAccessControls/insert
Turn on the Authorize requests using OAuth 2.0 button.
Set the bucket, object, entity and role fields.
Click execute.
You should see the resulting HTTP request and response.

Now make sure the request you are sending over the wire looks the same as this one.
