某些URL图像在某些设备中提供了下载错误

Question

我有一些URL图像，但有些图像没有显示并为Picasso或Glide提供错误下载..但是对于API 24的设备API 19或更低版本的错误下载没有问题，如下图

代码中的相同网址但未在右侧设备中显示（API 19）但在左侧显示（API24）：

我的守则

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ImageView imageView = (ImageView) findViewById(R.id.imageView);
    String url = "https://vid.alarabiya.net/images/2018/02/28/56cd42cd-c24e-473c-9701-2c361fdb92e8/56cd42cd-c24e-473c-9701-2c361fdb92e8_16x9_1200x676.JPG";


     Glide.with(this).load(url).into(imageView);



}

}

Answer 1

这是一个已知的问题。这与okhttp无法在Android 4.1-4.4上启用TLSv1.2有关。

看看这里https://github.com/square/okhttp/issues/2372更好地理解。

这是你的答案：你必须添加一个自定义GlideModule和两个依赖项

的build.gradle

implementation 'com.github.bumptech.glide:glide:4.6.1'
compile "com.github.bumptech.glide:okhttp3-integration:4.6.1"
compile 'com.github.bumptech.glide:annotations:4.6.1'

定制滑翔模块

import android.content.Context;
import android.os.Build;
import android.util.Log;

import com.bumptech.glide.Glide;
import com.bumptech.glide.Registry;
import com.bumptech.glide.annotation.GlideModule;
import com.bumptech.glide.integration.okhttp3.OkHttpUrlLoader;
import com.bumptech.glide.load.model.GlideUrl;
import com.bumptech.glide.module.AppGlideModule;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;

import javax.net.ssl.SSLContext;

import okhttp3.ConnectionSpec;
import okhttp3.OkHttpClient;
import okhttp3.TlsVersion;


@GlideModule
public class CustomGlideModule extends AppGlideModule {

    @Override
    public void registerComponents(Context context, Glide glide, Registry registry) {
        OkHttpClient client = getNewHttpClient();
        registry.replace(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(client));
    }


    private OkHttpClient getNewHttpClient() {
        OkHttpClient.Builder client = new OkHttpClient.Builder()
                .followRedirects(true)
                .followSslRedirects(true)
                .retryOnConnectionFailure(true)
                .cache(null)
                .connectTimeout(5, TimeUnit.SECONDS)
                .writeTimeout(5, TimeUnit.SECONDS)
                .readTimeout(5, TimeUnit.SECONDS);

        return enableTls12OnPreLollipop(client).build();
    }

    public static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client) {
        if (Build.VERSION.SDK_INT >= 16 && Build.VERSION.SDK_INT < 22) {
            try {
                SSLContext sc = SSLContext.getInstance("TLSv1.2");
                sc.init(null, null, null);
                client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

                ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                        .tlsVersions(TlsVersion.TLS_1_2)
                        .build();

                List<ConnectionSpec> specs = new ArrayList<>();
                specs.add(cs);
                specs.add(ConnectionSpec.COMPATIBLE_TLS);
                specs.add(ConnectionSpec.CLEARTEXT);

                client.connectionSpecs(specs);
            } catch (Exception exc) {
                Log.e("OkHttpTLSCompat", "Error while setting TLS 1.2", exc);
            }
        }

        return client;
    }


}

我已经测试过，它在API 19上运行。

希望这可以帮助。
