android – Picasso不支持下载使用https协议的图像

您好我正在使用Picasso库从URL下载图像.

网址：https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t1.0-1/s200x200/1472865_191408954385576_14109897_n.jpg

URL使用https协议,在这里我无法使用Picasso下载https协议的图像.

它不支持下载使用https协议的图像,只有当我使用http proctocol时它才对我有用吗？

在这里,我试图获取使用https协议的位图

com.squareup.picasso.Target target = new com.squareup.picasso.Target() {

@Override
public void onBitmapLoaded(Bitmap bitmap, LoadedFrom loadedFrom) {
    userProfile.setBitmap(bitmap);
    // call the Web API to register the walker here
    new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
        @Override
        public void onTaskCompleted(String jsonResponse) {
           Log.d(TAG, jsonResponse);
        }
    });
}

@Override
public void onBitmapFailed(Drawable drawable) {
    userProfile.setBitmap(null);
    // call the Web API to register the walker here
    new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
        @Override
        public void onTaskCompleted(String jsonResponse) {
           Log.d(TAG, jsonResponse);
        }
    }).execute();
}

@Override
public void onPrepareLoad(Drawable drawable) {}
};

Picasso.with(getActivity()).load(imgurl.toString()).into(target);

任何想法 ？

解决方法:

在Gradle中使用这些依赖项：

compile 'com.squareup.okhttp:okhttp:2.2.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'
compile 'com.squareup.picasso:picasso:2.4.0'

 public class PicassoTrustAll {

    private static Picasso mInstance = null;

    private PicassoTrustAll(Context context) {
        OkHttpClient client = new OkHttpClient();
        client.setHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });
        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[] {};
            }
        } };
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            client.setSslSocketFactory(sc.getSocketFactory());
        } catch (Exception e) {
            e.printstacktrace();
        }

        mInstance = new Picasso.Builder(context)
                .downloader(new OkHttpDownloader(client))
                .listener(new Picasso.Listener() {
                    @Override
                    public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                        Log.e("PICASSO", exception);
                    }
                }).build();

    }

    public static Picasso getInstance(Context context) {
        if (mInstance == null) {
             new PicassoTrustAll(context);
        }
        return mInstance;
    }
}

用法示例：

PicassoTrustAll.getInstance(context)
                .load(url)
                .into(imageView);
