javax.net.ssl.SSLHandshakeException：连接由 com.android.org.conscrypt.NativeCrypto.SSL_do_handshake（本机方法）处的对等方关闭

在 api 级别 24 之前，我的代码工作正常，但在 api 级别 24（7.0 Nougat）上出现错误。我不明白我的代码出了什么问题。

第一种方法在这里：

 <?xml version="1.0" encoding="utf-8"?> <network-security-config>
   <base-config> <trust-anchors> <certificates src="system"/>
   <certificates src="user"/> </trust-anchors> </base-config>
   <domain-config> <domain includeSubdomains="true">xyz.com</domain>
   <trust-anchors> <certificates src="@raw/my_ca"/> </trust-anchors>
   </domain-config> </network-security-config>

清单文件内部：

android:network Security Config = "@xml/network_security_config"我已经包括了network_security_config inside res/xml/network_security_config and ca证书在里面res/raw/my_ca.pem

建立 http 连接时：

public String CallWebService(String url, String soapAction, String envelope){


final HttpClient httpClient = ExSSLSocketFactory.getHttpsClient(new DefaultHttpClient());
    HttpParams params = httpClient.getParams();
    HttpConnectionParams.setConnectionTimeout(params, 150000);
    HttpConnectionParams.setSoTimeout(params, 150000);
    HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);
    HttpPost httppost = new HttpPost(url);
    httppost.setHeader("soapaction", soapAction);
    httppost.setHeader("Content-Type", "text/xml; charset=utf-8");

    String responseString = "";
    try
    {
        HttpEntity entity = new StringEntity(envelope);
        httppost.setEntity(entity);
        ResponseHandler<String> rh = new ResponseHandler<String>()
        {

            public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException
            {

                HttpEntity entity = response.getEntity();
                StringBuffer out = new StringBuffer();
                byte[] b = EntityUtils.toByteArray(entity);
                out.append(new String(b, 0, b.length));
                return out.toString();
            }
        };

        responseString = httpClient.execute(httppost, rh);
        Log.d("Response is here....", "responseString :  " + responseString);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    // close the connection
    httpClient.getConnectionManager().shutdown();
    return responseString;
}

我仍然收到错误：

请帮忙。 提前致谢。

确保您已设置启用 TLS从服务器端。
