java - Picasso 不会下载有效的 URL

Question

当我尝试从网站FilmAffinity下载图像时它不起作用，但对于其他网站的其他图像却可以。我使用的代码是

    Picasso.get().load("https://pics.filmaffinity.com/mamma_mia_here_we_go_again-440727588-mmed.jpg").into(imageView)

如果我使用回调，我会看到以下错误:com.squareup.picasso.NetworkRequestHandler$ResponseException: HTTP 403

用户似乎无权访问该网站，但如果我尝试在 Chrome 中打开相同的链接，它会完美地工作。

Picasso 不支持 https 方式。您可以引用一下方式:首先，您可以导入:

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'

并创建自定义类:

    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;
    }
}

你可以使用它:

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