[1.8.0] memoryCacheExtraOptions affixes the values to the Uri (https)

[chrisjenx]

I'm using .memoryCacheExtraOptions(512, 512) I'm not sure if this is the desired effect but by doing this when performing webrequests it now affixes the size to the end of the image.

https://d3jpl91pxevbkh.cloudfront.net/notha/image/upload/v1360769665/1.png becomes https://d3jpl91pxevbkh.cloudfront.net/notha/image/upload/v1360769665/1.png_512x512 Which of course fails loading.

Cheers, Chris

Maybe you have the problem with https, try this class:

public class AuthImageDownloader extends BaseImageDownloader {
    public static final String TAG = AuthImageDownloader.class.getName();

    public AuthImageDownloader(Context context, int connectTimeout, int readTimeout) {
        super(context, connectTimeout, readTimeout);
    }

    @Override
    protected InputStream getStreamFromNetwork(String imageUri, Object extra) throws IOException {

        URL url = null;
        try {
            url = new URL(imageUri);
        } catch (MalformedURLException e) {
            Log.e(TAG, e.getMessage(), e);
        }
        HttpURLConnection http = null;

        if (Scheme.ofUri(imageUri) == Scheme.HTTPS) {
            trustAllHosts();
            HttpsURLConnection https = (HttpsURLConnection) url
                    .openConnection();
            https.setHostnameVerifier(DO_NOT_VERIFY);
            http = https;
            http.connect();
        } else {
            http = (HttpURLConnection) url.openConnection();
        }

        http.setConnectTimeout(connectTimeout);
        http.setReadTimeout(readTimeout);
        return new FlushedInputStream(new BufferedInputStream(
                http.getInputStream()));
    }

    // always verify the host - dont check for certificate
    final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    /**
     * Trust every server - dont check for any certificate
     */
    private static void trustAllHosts() {
        // Create a trust manager that does not validate certificate chains
        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] x509Certificates,
                    String s) throws java.security.cert.CertificateException {
            }

            @Override
            public void checkServerTrusted(
                    java.security.cert.X509Certificate[] x509Certificates,
                    String s) throws java.security.cert.CertificateException {
            }

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[] {};
            }
        } };

        // Install the all-trusting trust manager
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection
                    .setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Nothing to do with SSL, this line actually returns an affixed Url which is why the image loader fails. (https://d3jpl91pxevbkh.cloudfront.net/notha/image/upload/v1360769665/1.png_512x512 which of course is bad) .

    @Override
    protected InputStream getStreamFromNetwork(URI imageUri, Object extra) throws IOException {
      Log.d(TAG, "URL="+imageUri.toString());
      //...
    }

I will look at fixing it in my fork. Seems that a certain flow makes it prefix to the wrong parts of the request.

[nostra13]

Did you found the reason?

Hello @nostra13 and @chrisjenx, I have a similar problem, Universal Image Downloader and SSL.

I want use the class you post before, but in the point to override getStreamFromNetwork:

public class AuthImageDownloader extends BaseImageDownloader { ... @Override protected InputStream getStreamFromNetwork(URI imageUri, Object extra) throws IOException { ... }

Happens this error, and i'm not sure how to fix:

The method getStreamFromNetwork(URI, Object) of type AuthImageDownloader must override or implement a supertype method

The quick fix is remove "@Override" annotation. But of course don't works.

Thanks.

[chrisjenx]

Just check that the correct method being overridden.

If eclipse is throwing an error on the override annotation it means that you are not overriding/extending the correct class thus the error.

[nostra13]

ImageDownloader changed its API, it uses String instead of URI. Updated my comment.

[Narfss]

Great, now works perfect.

Thanks, Is incredible how both answer so fast. ^^

This is my work around to the above bug:

The cause of this is still on my list todo.

[doridori]

Im having this issue too - this is no fun - and why is this thread marked closed?

[chrisjenx]

@doridori its not marked closed the other #163 is closed which referenced this.

[doridori]

oh sorry, my bad

[doridori]

@chrisjenx bug fix works great for

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
                .imageDownloader(new CustomImageDownloader(context)) //bug fix

[nostra13]

Still can't understand how it could happen.

[Lukafin]

Nostra, i am having problems with https and your solution posted above (using AuthImageDownloader class). The problem is in method encodeCredentials(), where it says that method for Configuration.getInstance() is undefined.

public static String encodeCredentials() {
       try {
           Configuration configuration = Configuration.getInstance();
           String auth = android.util.Base64.encodeToString((configuration.getHttpAuthLogin()
                + ":" + configuration.getHttpAuthPassword()).getBytes("UTF-8"),
                android.util.Base64.NO_WRAP);
           return auth;
       } catch (Exception ignored) {
           Log.e(TAG, ignored.getMessage(), ignored);
       }
       return "";
   }

I am missing something? What are the needed imports for above code? If i import android.content.res.Configuration, i get even more errors?

[nostra13]

You should use this authorization only if you need. I guess you don't. I updated AuthImageDownloader code, check it out.

[Lukafin]

Works! I used code below to make it work:

   ImageLoaderimageLoader = ImageLoader.getInstance();

    DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
            .cacheInMemory()
            .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2).build();

    Builder configBuilder = new ImageLoaderConfiguration.Builder(getActivity());
    configBuilder.imageDownloader(new AuthImageDownloader(getActivity(), 1000, 1000));
    configBuilder.defaultDisplayImageOptions(defaultOptions);
    ImageLoaderConfiguration config=configBuilder.build();

    imageLoader.init(config);

Thank you very much for your quick answer.

[doridori]

I see this is closed - does it now not append the dimensions to the end of the URL?

[nostra13]

It didn't append the dimensions before. I couldn't reproduce the bug and couldn't imagine why it can happen. chrisjenx promised to look into it but he didn't I guess. If you have this bug then you can send me your project with this bug so I'll look into it.

[chrisjenx]

This bug is still very active. I'm out of the county so no chance to fix. Dori can you confirm in 1.8.2 see if still an issue?

[PankovSerge]

Got this issue with 1.9.3 and https in link. Use AuthImageDownloader from your comment.

[HarryMMR]

As suggested, I tried to use AuthImageDownloader to ignore SSL cert error. But from log cat, it seems that AuthImageDownloader override method is not being called and i still get same ssl error. I already set ".imageDownloader(new AuthImageDownloader(getApplicationContext(),5000,5000)) " in ImageLoaderConfiguration. Help please!

[huluwa-dev]

Got this issue with 1.9.4....How to solve it???

[HarryMMR]

Have anyone found a fix? I need it ASAP.

[zhdh2008]

@nostra13 Your code works well, thanks ps: The version of UIL I use is 1.9.5
