두 클래스를 만들었습니다 : -이 중 하나는 OkHttp를 확장하고 새로운 메소드 getUnsafeOkHttpClient()를가집니다.SSL 인증을 사용하여 okhttp를 생성하는 방법
public class GetExampleOkHttp extends OkHttpClient {
public OkHttpClient getUnsafeOkHttpClient() {
try {
// Create a trust manager that does not validate certificate chains
final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType)
throws CertificateException {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType)
throws CertificateException {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}
} };
// Install the all-trusting trust manager
final SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
// Create an ssl socket factory with our all-trusting manager
final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.sslSocketFactory(sslSocketFactory);
builder.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
OkHttpClient okHttpClient = builder.build();
return okHttpClient;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
그리고 다른 Main 클래스 :
class ExampleOkHttpMain
public static void main(String[] args) throws IOException {
GetExampleOkHttp example = new GetExampleOkHttp();
example.getUnsafeOkHttpClient();
Request request = new Request.Builder()
.url("https://lachuzhnikov.kiev.ua/test.txt")
.build();
Response response = example.newCall(request).execute();
System.out.println(response.body().string());
}
}
하지만 여전히 오류가 있습니다
