I'm using Retrofit (with RxJava) to download a text file.
#Streaming
#GET
Observable<ResponseBody> download(#Url String file);
Everything works fine except when user is using a public wifi that need web authentication. In this case download is still successful and what I receive is a file contains HTML of that authentication web page. How do I check and raise error in this case? I tried with Interceptor, NetworkInterceptor (Okhttp), disable redirect (Retrofit) but no luck because no exception is thrown.
Either checksum your file and check it when you get it, or check the Content-type:
#Streaming
#GET
Observable<Response<ResponseBody>> download(#Url String file);
download("http://...")
.map(response -> {
if(!"application/my-content-type".equals(
response.headers("Content-Type")) {
throw new RuntimeException("Bad download");
}
return resource.body();
})

I have a link to default email verification function in Firebase.
Using this link from the browser works fine, however it fails when being used from server side with the following code:
try {
const url = `https://example.com/__/auth/action?mode=verifyEmail&oobCode=${oobCode}&apiKey=${apiKey}&lang=en`;
const response = await axios.get(url);
if (response.data.success) {
return next();
} else {
return next(new ErrorResponse("Failed email verification", FORBIDDEN));
}
} catch (error) {
return sendFailedWithErr(res, error.message);
}
When I am copying the URL used in the server side the exact same URL works from the browser, but fails on the server side.
Would appreciate any idea what is the problem.
This is because a call to this URL is not going to return a response that you can check like the response of a REST API endpoint with, e.g. response.data.success.
As you will see here, this URL is supposed to be used to open a web page in which you will:
Get the values passed as QueryString parameters (e.g. mode or oobCode)
Call, from the web page some methods of the Firebase JavaScript SDK, like applyActionCode() in the case of email verification.
You may be able to mimic this action from a server, but I've never tried.
So I got a template of a Flutter app that retrieves all its data from a website using HTTP get requests.
I have the following method that gets the list of resturaunts:
Future<Stream<Restaurant>> getNearRestaurants(LocationData myLocation, LocationData areaLocation) async {
String _nearParams = '';
String _orderLimitParam = '';
if (myLocation != null && areaLocation != null) {
_orderLimitParam = 'orderBy=area&limit=5';
_nearParams = '&myLon=${myLocation.longitude}&myLat=${myLocation.latitude}&areaLon=${areaLocation.longitude}&areaLat=${areaLocation.latitude}';
}
final String url = '${GlobalConfiguration().getString('api_base_url')}restaurants?$_nearParams&$_orderLimitParam';
final client = new http.Client();
final streamedRest = await client.send(http.Request('get', Uri.parse(url)));
return streamedRest.stream.transform(utf8.decoder).transform(json.decoder).map((data) => Helper.getData(data)).expand((data) => (data as List)).map((data) {
return Restaurant.fromJSON(data);
});
}
However when I swap the template's url variable for my own website, the app gets stuck since it cannot retrieve the same information from my website.
What could I be missing? Is the problem in the flutter code or the website?
Update 1:
I surrounded it with a try/catch block and it gave me a "bad certificate exception.". This might be because my website does not have a SSL certificate, so I added an exception to the HttpClient for my self-certified website:
bool _certificateCheck(X509Certificate cert, String host, int port) =>
host == '<domain>';
HttpClient client2 = new HttpClient()..badCertificateCallback = (_certificateCheck);
HttpClientRequest request = await client2.getUrl(Uri.parse(url));
var response = await request.close(); // sends the request
// transforms and prints the response
response.transform(Utf8Decoder()).listen(print);
This code showed a Error 404: Not found on the page that I need to get my JSON data from.
I also installed postman and checked my website with the GET statement for the same list of restaurants I try to retrieve in the flutter code posted above and see this:
Postman GET screenshot
Update 2:
So I configured SSL on my website and the problem still persists. I tried testing the GET request via postman and it returns a error 404 page as well. I have tried going through my server files and laravel logs and nothing did the trick.
Its as if my website cannot route to the specific pages in my API folder. BUt they are all defined in api.php.
I am trying to play Widevine encrypted content on an Android TV application using Exoplayer. I have my video URL which is served from a CDN and acquired with a ticket. I have my widevine license URL, a ticket and a auth token for the license server.
I am creating a drmSessionManager, putting the necessary headers needed by the license server as follows:
UUID drmSchemeUuid = C.WIDEVINE_UUID;
mediaDrm = FrameworkMediaDrm.newInstance(drmSchemeUuid);
static final String USER_AGENT = "user-agent";
HttpMediaDrmCallback drmCallback = new HttpMediaDrmCallback("my-license-server", new DefaultHttpDataSourceFactory(USER_AGENT));
keyRequestProperties.put("ticket-header", ticket);
keyRequestProperties.put("token-header", token);
drmCallback.setKeyRequestProperty("ticket-header", ticket);
drmCallback.setKeyRequestProperty("token-header", token);
new DefaultDrmSessionManager(drmSchemeUuid, mediaDrm, drmCallback, keyRequestProperties)
After this Exoplayer handles most of the stuff, the following breakpoints are hit.
response = callback.executeKeyRequest(uuid, (KeyRequest) request);
in class DefaultDrmSession
return executePost(dataSourceFactory, url, request.getData(), requestProperties) in HttpMediaDrmCallback
I can observe that everything is fine till this point, the URL is correct, the headers are set fine.
in the following piece of code, I can observe that the dataSpec is fine, trying to POST a request to the license server with the correct data, but when making the connection the response code returns 405.
in class : DefaultHttpDataSource
in method : public long open(DataSpec dataSpec)
this.dataSpec = dataSpec;
this.bytesRead = 0;
this.bytesSkipped = 0;
transferInitializing(dataSpec);
try {
connection = makeConnection(dataSpec);
} catch (IOException e) {
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
try {
responseCode = connection.getResponseCode();
responseMessage = connection.getResponseMessage();
} catch (IOException e) {
closeConnectionQuietly();
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
When using postman to make a request to the URL, a GET request returns the following body with a response code of 405.
{
"Message": "The requested resource does not support http method 'GET'." }
a POST request also returns response code 405 but returns an empty body.
In both cases the following header is also returned, which I suppose the request must be accepting GET and POST requests.
Access-Control-Allow-Methods →GET, POST
I have no access to the configuration of the DRM server, and my contacts which are responsible of the DRM server tells me that POST requests must be working fine since there are clients which have managed to get the content to play from the same DRM server.
I am quite confused at the moment and think maybe I am missing some sort of configuration in exoplayer since I am quite new to the concept of DRMs.
Any help would be greatly appreciated.
We figured out the solution. The ticket supplied for the DRM license server was wrong. This works as it is supposed to now and the content is getting played. Just in case anyone somehow gets the same problem or is in need of a basic Widevine content playing code, this works fine at the moment.
Best regards.
I need to download a text file using basic authentication (the kind of authentication that prompts the browser to ask you for domain\username and password) using Groovy. I would like to avoid using additional libraries, isn't there anything to do this in in Groovy?
My current code is:
new File("test.txt").withOutputStream { out ->
def url = new URL(myurl).openConnection()
def remoteAuth = "Basic " + "myusername:mypassword".bytes.encodeBase64()
url.setRequestProperty("Authorization", remoteAuth);
out << url.inputStream
}
But the server replies with a 401 error. What should I do?
Groovy uses the java.net.Authenticator API. You can provide a default Authenticator using java.net.Authenticator#setDefault. An Example for an BasicAuth usage can be found in another Answer.
Authenticator.setDefault (new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication ("username", "password".toCharArray());
}
});
All, I'm trying to upload a file in dam in CQ using assestManager and then trying to set values in metadata. Then I'm retrieving all the data one by one and storing in a list, and set it to request object and pass it to new jsp page using 'rd.forward(request, response);' but I'm getting error as:
javax.jcr.AccessDeniedException: Access denied.
even though all the access are given.
Code:-
String redirect = request.getParameter(":redirect"); //content/nextgen/marine/podupload.html
RequestDispatcher rd = request.getRequestDispatcher(redirect);
rd.forward(request, response); // throws me error as access denied
I'm assuming your initial request is a POST?
If so, try the following:
SlingHttpServletRequest newRequest = new SlingHttpServletRequestWrapper(request) {
public String getMethod() {
return "GET";
}
};
newRequest.getRequestDispatcher("/content/nextgen/marine/podupload.html")
.forward(newRequest, response);
If this is a GET request that you are trying to forward then it's a permission issue. If this is a POS or PUT request then you will need a SlingHttpServletRequestWrapper to wrap and modify your request as a GET request forward.
This is simply because sling cannot forward POST requests.
