Glide沒有顯示來自後端URL的圖像

Question

我正在使用android並使用'backendless'作爲mbass。我已經在他們的文件存儲器中上傳了一張圖片，並且我收到了一個用於圖像檢索的公開網址。我通過簡單的'HttpURLConnection'成功檢索圖像，但是當我使用滑動時，它總是停留在'錯誤'而不是檢索圖像。並滑動工作在我從谷歌複製的其他網址，它工作正常。但是我給了後端的URL，它不起作用。

Glide.with(getContext()) 
        .load("https://api.backendless.com/CF512434-CCA8-067C-FF92-D76481A44000/v1/files/profilePhotos/mubtada.syedprofileImage.png") 
        .placeholder(R.drawable.ic_video_call_white_36dp) 
        .error(R.drawable.loginbackground) 
        .into(ImageView); 

和滑行版本：3.7.0

這裏是我的backendless網址：https://api.backendless.com/CF512434-CCA8-067C-FF92-D76481A44000/v1/files/profilePhotos/mubtada.syedprofileImage.png

Answer 1

我使用滑翔得到了圖像在我的設備。請找到附件圖片。

（版本：編譯 'com.github.bumptech.glide：滑翔：3.6.1'）

ImageView imageView = (ImageView) findViewById(R.id.imageView); 
    Glide.with(this) 
      .load("https://api.backendless.com/CF512434-CCA8-067C-FF92-D76481A44000/v1/files/profilePhotos/mubtada.syedprofileImage.png") 
      .placeholder(new ColorDrawable(ContextCompat.getColor(MainActivity.this, R.color.placeholder_gray))) 
      .error(new ColorDrawable(ContextCompat.getColor(MainActivity.this, R.color.placeholder_gray))) 
      .into(imageView); 

Answer 2

也許是因爲支持HTTPS的。

gradle這個

compile 'com.squareup.okhttp3:okhttp:3.3.1' 
compile 'com.github.bumptech.glide:glide:3.7.0' 
compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar' 

HttpsUtils

public class HttpsUtils{ 
public static SSLSocketFactory getSslSocketFactory(InputStream[] certificates, InputStream bksFile, String password){

     } else{ 
      trustManager = new UnSafeTrustManager(); 
     } 
     sslContext.init(keyManagers, new TrustManager[]{trustManager}, new SecureRandom()); 
     return sslContext.getSocketFactory(); 
    } catch (NoSuchAlgorithmException e){ 
     throw new AssertionError(e);

    return null; 
} 

private static class MyTrustManager implements X509TrustManager{

    public MyTrustManager(X509TrustManager localTrustManager) throws NoSuchAlgorithmException, KeyStoreException{

RetrofitUtils

public class RetrofitUtils { 
public static OkHttpClient getOkHttpClient(InputStream... certificates) 
{ 
    SSLSocketFactory sslSocketFactory = HttpsUtils.getSslSocketFactory(certificates, null, null); 
    OkHttpClient.Builder builder = new OkHttpClient().newBuilder(); 
    builder = builder.sslSocketFactory(sslSocketFactory); 
    builder.hostnameVerifier(new HostnameVerifier() { 
     @Override 
     public boolean verify(String hostname, SSLSession session) 
     { 
      return true; 
     } 
    }); 
    return builder.build(); 
} 

} 應用

Glide.get(this).register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(RetrofitUtils.getOkHttpClient())); 

最後

 Glide.with(this).load("https://api.backendless.com/CF512434-CCA8-067C-FF92-D76481A44000/v1/files/profilePhotos/mubtada.syedprofileImage.png").centerCrop().into(iv_icon);
