我的项目中使用网络请求库是webservice方式实现，依赖包版本是ksoap2-android-assembly-3.3.0-jar-with-dependencies.jar。

        return null;
    }
}

在发出https请求前调用一次SslRequest.allowAllSSL(“”,context);证书验证（可以写在程序的第一个Activity中）,验证成功后，后续调用https请求即可。

由于我的项目使用的是ksoap框架调用webservice，之前用的是http请求：

public final static String WEBSERVICE_BUS_URL = "http://180.89.58.20:xxxx/bus_service_new/ServicesFacadePort?wsdl";(url类型)
public final static String BUS_SERVICE_NAMESPACE = "http://xxx.xxxx.com.cn/";(命名空间)
String method = "getSystem";(方法名)
private static HttpTransportSE transport;
transport = new HttpTransportSE(AppUtil.WEBSERVICE_BUS_URL, AppUtil.TIMEOUT);
---------------------------------envelope----------
String url;
        String serviceNamespace;

            url = AppUtil.WEBSERVICE_BUS_URL;
            serviceNamespace = AppUtil.BUS_SERVICE_NAMESPACE;

        SoapObject request = new SoapObject(serviceNamespace, method);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        Element el = new Element().createElement(serviceNamespace, "TCPSHeader");
        el.setAttribute(serviceNamespace, "accessType", AppUtil.ACCESSTYPE);（可以用于区分ios和android，规则自己定，比如AppUtil.ACCESSTYPE = “1”代表android）
        el.setAttribute(serviceNamespace, "productID", AppUtil.PRODUCTID);（唯一）
        el.setAttribute(serviceNamespace, "version", AppUtil.VERSION);(apk版本号,只是便于记录，可以随意)
        header[0] = el;
        envelope.headerOut = header;
        envelope.dotNet = false;
        //这里可以加密传参
        if (param != null) {
            for (int n = 0; n < param.length; n++) {
                request.addProperty("arg" + n, param[n]);
            }
        }
        envelope.bodyOut = request;
---------------------------------envelope----------

//base64.register(envelope);（加密注册）
        Log.i("调用时间-----------------------", String.valueOf(System.currentTimeMillis()));
        try {
            transport.call(url, envelope);
            System.out.println(
                    "-----------------" + "请求的数据" + request.toString() + "返回： " + envelope.getResponse().toString());（返回数据也可以加密，在需要的地方再解密）
            return envelope.getResponse();
        } catch (Exception e) {

            if (e instanceof SocketTimeoutException) {
                return R.string.error_timeout;（超时）
            } else {
                return R.string.error_unknown;（未知错误）
            }
        }

改为https请求后，只需要将HttpTransportSE换成HttpsTransportSE，然后：

public final static String WEBSERVICE_BUS_URL = "http://180.89.58.20:xxxx/bus_service_new/ServicesFacadePort?wsdl";(url类型)
public final static String BUS_SERVICE_NAMESPACE = "http://xxx.xxxx.com.cn/";(命名空间)
String nameSpace = "";
        String URL = "";
        String HOST = "";
        String WS_OPS = "";
        String SOAP_ACTION = "";
        String METHOD_NAME = method;
        Integer POST = 0;
if (URL.startsWith("https")){
                /* * https请求 */
                nameSpace = AppUtil.BUS_SERVICE_NAMESPACE;
                URL = AppUtil.WEBSERVICE_BUS_URL;
                HOST = "180.89.58.20";
                WS_OPS = "/bus_service_new/ServicesFacadePort?wsdl";（指AppUtil.WEBSERVICE_BUS_URL去掉HOST和POST后的部分）
                SOAP_ACTION = nameSpace + method;
                POST = xxxx;

             }
HttpsTransportSE androidHttpTransport = new HttpsTransportSE(HOST,POST,WS_OPS,AppUtil.TIMEOUT);
        androidHttpTransport.debug = true;
        //去掉ssl证书验证
// SslRequest.allowAllSSL(URL,mContext);（在程序每次启动时已调用，就不用每次调用接口时去重复验证了）

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);(envelope不变，参照上面的http请求方式)
            if (envelope.getResponse() != null) {
                result_return = envelope.getResponse().toString();
                LogUtils.e("--------------------------------", "返回结果" + result_return);

            }
        } catch (Exception e) {
            if (e instanceof SocketTimeoutException) {
                result_return = String.valueOf(R.string.error_timeout);
            } else {
                result_return = String.valueOf(R.string.error_unknown);
            }
        }

主要是多了一步证书验证。客户端请求类由http换成https类型，方法都封装在那个ksoap包中。
