无法使用OKHTTP3在IBM JRE8上提取信任管理器

问题描述

任何人都可以帮忙吗？

我还使用 OKHTTP3版本4.8.1 编写 HTTP2客户端。它适用于Oracle JDK 8，但不适用于IBM JRE 8。

错误消息： java.lang.IllegalStateException：无法在okhttp3.internal.Platform@e85a0ce8上提取信任管理器，sslSocketFactory是com.ibm.jsse2.SSLSocketFactoryImpl类。

谢谢

解决方法

您所使用的方法已经过时了

https://github.com/square/okhttp/blob/cd722373281202492043f4294fccfe6f691ddc01/okhttp/src/main/kotlin/okhttp3/OkHttpClient.kt#L741

之所以弃用它，是因为它不得不对JVM进行很多假设，这在每次JVM更新或跨供应商时都会中断。您应该改为使用X509TrustManager作为参数来调用该方法

https://github.com/square/okhttp/blob/cd722373281202492043f4294fccfe6f691ddc01/okhttp/src/main/kotlin/okhttp3/OkHttpClient.kt#L767

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init((KeyStore) null);
TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
    throw new IllegalStateException("Unexpected default trust managers:"
        + Arrays.toString(trustManagers));
}
X509TrustManager trustManager = (X509TrustManager) trustManagers[0];

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null,new TrustManager[] { trustManager },null);
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

OkHttpClient client = new OkHttpClient.Builder()
    .sslSocketFactory(sslSocketFactory,trustManager)
    .build();
