本文提供了一种解决使用ImageLoader时遇到的SSL证书验证错误（java.security.cert.CertPathValidatorException）的方法。通过修改BaseImageDownloader.java文件中的createConnection方法，并引入FakeX509TrustManager类来信任所有SSL证书，从而绕过证书验证问题。

最近使用imageloader 发现ssl问题（java.security.cert.CertPathValidatorException）

网上找了个方法，亲测通过，如下：

universalimageloader/core/download/BaseImageDownloader.java文件中

protected HttpURLConnection createConnection(String url, Object extra)
throws IOException {
FakeX509TrustManager.allowAllSSL();// 允许所有ssl证书

String encodedUrl = Uri.encode(url, ALLOWED_URI_CHARS);
HttpURLConnection conn = (HttpURLConnection) new URL(encodedUrl)
.openConnection();
conn.setConnectTimeout(connectTimeout);
conn.setReadTimeout(readTimeout);
return conn;
}

public static class FakeX509TrustManager implements X509TrustManager {
private static TrustManager[] trustManagers;
private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[0];

public void checkClientTrusted(X509Certificate[] x509Certificates,
String s) throws CertificateException {
}

public void checkServerTrusted(X509Certificate[] x509Certificates,
String s) throws CertificateException {
}

public X509Certificate[] getAcceptedIssuers() {
return _AcceptedIssuers;
}

public static void allowAllSSL() {
HttpsURLConnection
.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
});
SSLContext context = null;
if (trustManagers == null) {
trustManagers = new TrustManager[] { new FakeX509TrustManager() };
}
try {
context = SSLContext.getInstance("TLS");
context.init(null, trustManagers, new SecureRandom());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}
HttpsURLConnection.setDefaultSSLSocketFactory(context
.getSocketFactory());
}
}
