如何使用ssl证书创建okhttp

Question

我创建了两个类：-这一个扩展了OkHttp，并有一个新方法getUnsafeOkHttpClient（）。

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);
        }
    }
}

和其他主要类别：

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());       
    }
}

但我仍然有一个错误：

线程“main”javax中出现异常。网ssl。SSLHandshakeException：太阳。安全验证器。ValidatorException:PKIX路径生成失败：sun。安全供应商。证书路径。SunCertPathBuilderException：无法在sun上找到请求目标的有效证书路径。安全ssl。警报。sun上的getSSLException（未知源）。安全ssl。SSLSocketImpl。在太阳下致命（未知来源）。安全ssl。握手器。fatalSE（未知来源）

Answer 1

3：备份Java\jdk...\jre\lib\Security\cacerts（例如：C：\Program Files\Java\jdk1.7.0_79\jre\lib\Security）
4：将cacerts复制到另一个文件夹
5：端口打开文件cacerts（传递：更改）在步骤2中导入cer并保存
6：复制并替换新的cacertsJava\jdk...\jre\lib\Security\cacerts
