Glide 不显示来自 backendless URL 的图像

Question

我正在研究 android 并使用 'backendless' 作为 mbass。我已经在他们的文件存储中上传了一张图片，我得到了一个 public URL 用于图像检索。我通过简单的 'HttpURLConnection' 成功检索了图像，但是当我使用 glide 时，它总是停留在 'error' 而不是检索图像。并且 glide 在我从 Google 复制的其他 URL 上工作并且工作正常。但是我给了 backendless 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);

glide 版本为：3.7.0

这是我的后台URL：https://api.backendless.com/CF512434-CCA8-067C-FF92-D76481A44000/v1/files/profilePhotos/mubtada.syedprofileImage.png

Answer 1

我使用 Glide 在我的设备中获取了图像。请找到所附图片。

(版本：编译'com.github.bumptech.glide:glide: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);

可能是支持Https的缘故

gradle

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'

        SSLContext sslContext = SSLContext.getInstance("TLS");
        TrustManager trustManager = null;
        if (trustManagers != null){
            trustManager = new MyTrustManager(chooseTrustManager(trustManagers));
        } else{
            trustManager = new UnSafeTrustManager();
        }
        sslContext.init(keyManagers, new TrustManager[]{trustManager}, new SecureRandom());

}

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();
}

} 申请

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

终于

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