Android 访问 https的webservice接口

公司后端使用webservice 做的接口，以前用的http 自己封装的webserviceUtils请求一直没有问题，最近接口地址修改为https 导致了我这边的请求一直无法响应，在网上翻来复去找了一天的也没有找到有效的方法，好在功夫不负有心人，终于在官方问题库中查找到了相关的问题
原因是因为https证书的问题
问题链接soap - KSOAP 2 Android with HTTPS - Stack Overflow
我这边使用的是最新版的soap-android jar包这边附上官方jar包下载第一个具体项目怎么引用不用我多说了吧

好了废话不多说直接上原码：

package com.example.corlibrmodule.utils.webservice;import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;/*** @author 小訾* @description: 关于webservice 请求https 添加验证* @date :2022/3/10 14:23*/
public class FakeX509TrustManager implements X509TrustManager {private static TrustManager[] trustManagers;private static final X509Certificate[] _AcceptedIssuers = newX509Certificate[] {};@Overridepublic void checkClientTrusted(X509Certificate[] chain, StringauthType) throws CertificateException {}@Overridepublic void checkServerTrusted(X509Certificate[] chain, StringauthType) throws CertificateException {}public boolean isClientTrusted(X509Certificate[] chain) {return true;}public boolean isServerTrusted(X509Certificate[] chain) {return true;}@Overridepublic X509Certificate[] getAcceptedIssuers() {return _AcceptedIssuers;}public static void allowAllSSL() {HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){@Overridepublic boolean verify(String hostname, SSLSession session) {return true;}});SSLContext context = null;if (trustManagers == null) {trustManagers = new TrustManager[] { new FakeX509TrustManager() };}try {context = SSLContext.getInstance("TLS");context.init(null, trustManagers, new SecureRandom());} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (KeyManagementException e) {e.printStackTrace();}HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());}
}

我们重写了https验证然后请看WebServiceUtils的相关代码

}

然后代码到此基本可以解决关于请求https 的webservice接口了不过本着java 封装集成多态的原则我这边对WebServiceUtils 进行了二次封装方便调用方便模块化开发可以把这两个请求类放到公共module中就行

package com.example.corlibrmodule.utils.webservice;import android.content.Context;
import android.support.v4.util.SimpleArrayMap;
import android.util.Log;import com.example.corlibrmodule.CorLibUtils;
import com.example.corlibrmodule.utils.JSONParser;import org.ksoap2.serialization.SoapObject;/*** web service 请求及返回封装** @author 小訾  2020/3/4*/public class XWebService {public interface OnResultListener<T> {void onSuccess(T bean);void onError();}public interface OnKotlinResultListener {void onSuccess(String bean);void onError();}/*** 获取web service 数据 for java** @param methodName       方法名* @param arrayMap         传值 map* @param onResultListener web service 请求返回监听* @param <T>              返回数据泛型*/public static <T> void getIntentData(Context activity, Class<T> clazz, final String methodName,final SimpleArrayMap<String, String> arrayMap,final OnResultListener<T> onResultListener) {WebServiceUtils.create().call(activity, CorLibUtils.getBaseUrl(), CorLibUtils.getBaseNameSpace(), methodName, arrayMap, new WebServiceUtils.Response() {@Overridepublic void onSuccess(SoapObject result) {if (result != null) {String mJson = result.getProperty(0).toString();Log.i("xiaozi", "服务端获取的JSON---->" + methodName + "---->" + mJson);T data = JSONParser.fromJson(mJson, clazz);onResultListener.onSuccess(data);}}@Overridepublic void onError(Exception e) {onResultListener.onError();}@Overridepublic void Loading() {}});}/*** 获取web service 数据 for kotlin** @param methodName       方法名* @param arrayMap         传值 map* @param onResultListener web service 请求返回监听*/public static void getIntentData(Context activity, final String methodName,final SimpleArrayMap<String, String> arrayMap,final OnKotlinResultListener onResultListener) {WebServiceUtils.create().call(activity, CorLibUtils.getBaseUrl(), CorLibUtils.getBaseNameSpace(), methodName, arrayMap, new WebServiceUtils.Response() {@Overridepublic void onSuccess(SoapObject result) {if (result != null) {int propertyCount = result.getPropertyCount();if (propertyCount == 0) {onResultListener.onError();} else {String mJson = result.getProperty(0).toString();Log.i("xiaozi", "服务端获取的JSON---->" + methodName + "---->" + mJson);onResultListener.onSuccess(mJson);}}}@Overridepublic void onError(Exception e) {onResultListener.onError();}@Overridepublic void Loading() {}});}}

下面是调用方法代码项目的接口工具类只需继承 XWebService就可以了

package com.example.zzrmyy.http;import android.app.Activity;
import android.support.v4.util.SimpleArrayMap;
import android.text.TextUtils;
import android.util.Log;import com.example.corlibrmodule.CorLibUtils;
import com.example.corlibrmodule.bean.BaseEntity;
import com.example.corlibrmodule.utils.webservice.XWebService;
import com.example.zzrmyy.CustomApplication;
import com.example.zzrmyy.bean.OrderInOutEntity;
import com.example.zzrmyy.bean.PharmacyDrugDetails;
import com.example.zzrmyy.bean.UserInfoEntity;
import com.example.zzrmyy.ui.yaofang.bean.ResultEntity;
import com.example.zzrmyy.ui.yaoku.bean.SearchDrugEntity;
import com.example.zzrmyy.utils.ZDYSharedPreferences;/*** * 项目webservice 请求工具类* @author 小訾  2020/3/4*/public class ZDYWebService extends XWebService {/*** 登陆** @param name             用户名* @param psw              密码* @param onResultListener*/public static void login(Activity activity, Class clazz, String name, String psw, OnResultListener<UserInfoEntity> onResultListener) {SimpleArrayMap<String, String> arrayMap = new SimpleArrayMap<>();arrayMap.put("userName", name);arrayMap.put("passWord", psw);Log.i("xiaozi",  CorLibUtils.getBaseUrl() + UrlConfig.methods_login + "\n map=" + arrayMap.toString());getIntentData(activity, clazz, UrlConfig.methods_login,  arrayMap, onResultListener);}}

希望这个方法可以帮大家解决到问题。
