如何让 Unirest(java) 忽略证书错误

我正在使用 Unirest（java 版本）发出 GET 和 POST 请求。但是在访问 SSL 加密站点时遇到问题，因为我的程序位于公司网络后面，并且网络管理员为我设置了防火墙映射。例如foobar.com被映射到56.1.89.12:4444。但是当我向该地址发出请求时，我会收到以下 ssl 证书错误：

com.mashape.unirest.http.exceptions.UnirestException: javax.net.ssl.SSLException: hostname in certificate didn't match: <56.1.89.12> != <www.foobar.com>
    at com.mashape.unirest.http.HttpClientHelper.request(HttpClientHelper.java:131)
    at com.mashape.unirest.request.BaseRequest.asString(BaseRequest.java:52)

I see Unirest具有使用自定义的高级配置httpclient.所以我用

Unirest.setHttpClient(MyHttpClient.makeClient());
HttpResponse<String> res = null;
try {
    res = Unirest.get(urlstr).asString();
} catch (UnirestException e) {
    e.printStackTrace();
}
String jsonstr = res.getBody();

the makeClient的方法MyHttpClient is:

public static HttpClient makeClient(){
 SSLContextBuilder builder = new SSLContextBuilder();
 CloseableHttpClient httpclient = null;
    try {
        // builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
        builder.loadTrustMaterial(null, new TrustStrategy(){
            public boolean isTrusted(X509Certificate[] chain, String authType)
                throws CertificateException {
                return true;
            }
        });
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                builder.build());
        httpclient = HttpClients.custom().setSSLSocketFactory(
                sslsf).build();
        System.out.println("custom httpclient called");
        System.out.println(httpclient);

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }

return httpclient;
}

主要思想取自忽略 Apache HttpClient 4.3 中的 SSL 证书 https://stackoverflow.com/questions/19517538/ignoring-ssl-certificate-in-apache-httpclient-4-3

但这仍然不起作用。有什么建议吗？

 SSLContext sslcontext = SSLContexts.custom()
            .loadTrustMaterial(null, new TrustSelfSignedStrategy())
            .build();

    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext,SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
    CloseableHttpClient httpclient = HttpClients.custom()
            .setSSLSocketFactory(sslsf)
            .build();
    Unirest.setHttpClient(httpclient);

这对我有用
