您只需搜索匹配条件（Using find）的JSON数组 在这种情况下，“质量” ===“ hd720”

SSLContext sslContext = SSLContexts.custom()
        .loadTrustMaterial((chain, authType) -> true)
        .build();

CloseableHttpClient client = HttpClients.custom()
        .setSSLSocketFactory(new SSLConnectionSocketFactory(sslContext,
                new String[]{"SSLv3", "TLSv1", "TLSv1.1", "TLSv1.2"},
                null,
                NoopHostnameVerifier.INSTANCE))
        .build();
