0、主要思路:使用axis2發布webservice服務端,微信小程序作為客戶端訪問。步驟如下:
1、服務端:
首先微信小程序僅支持訪問https的url,且必須是已備案域名。因此前期的服務器端工作需要先做好,本人是申請了個人域名(已備案),並使用阿里雲服務器,然后申請免費SSL,通過配置tomcat完成支持https訪問。此外,intellJ IDE的java編譯器版本調整到8以上。
下面進入正題:
pom.xml添加:
<!--Axis發布webservice--> <!--servlet依賴--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <!--服務端--> <dependency> <groupId>org.apache.axis2</groupId> <artifactId>axis2</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>org.apache.axis2</groupId> <artifactId>axis2-transport-http</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>org.apache.axis2</groupId> <artifactId>axis2-transport-local</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>org.apache.xmlbeans</groupId> <artifactId>xmlbeans</artifactId> <version>2.4.0</version> </dependency> <!--axis2 客戶端--> <dependency> <groupId>org.apache.axis2</groupId> <artifactId>axis2-adb</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>org.apache.axis2</groupId> <artifactId>axis2-kernel</artifactId> <version>1.6.2</version> </dependency>
在webapp下的WEB-INF下新建如下目錄:
其中axis2.xml文件鏈接:https://files.cnblogs.com/files/qianyou304/axis2.xml
在里面添加,以支持https訪問:
<transportReceiver name="https" class="org.apache.axis2.transport.http.AxisServletListener"> <parameter name="port">443</parameter> </transportReceiver>
services.xml代碼:
<?xml version="1.0" encoding="UTF-8"?> <serviceGroup> <!-- 指定服務名,隨便定義 --> <service name="xxx" > <!-- 服務的作用說明,可寫可不寫 --> <description>webservice服務</description> <!-- 指定要發布的類路徑 自定義name--> <parameter name="ServiceClass">com.cn.hnust.webservice.server.xxxx</parameter> <!-- 類里面的方法名 ,若有多個方法,可以新增operation標簽 --> <operation name="xxxx"> <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/> </operation> </service> </serviceGroup>
指定發布類,這里隨便給一個名字:ILockService,隨便取一個方法名:invoke
import com.cn.hnust.service.IUserRecordService; import net.sf.json.JSONArray; import net.sf.json.JSONObject; import org.springframework.web.context.support.WebApplicationContextUtils; /** * */ public class ILockService implements ServletContextListener{ /**
* 留作備用
*/
static IUserRecordService userRecordService; @Override public void contextInitialized(ServletContextEvent sce) { userRecordService = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext()).getBean(IUserRecordService.class); } @Override public void contextDestroyed(ServletContextEvent sce) { } public String invoke(String xmlData) { System.out.println("xml: "+xmlData); String result = ""; JSONObject jsonObject = new JSONObject(); jsonObject = JSONObject.fromObject(xmlData); String name_method = jsonObject.getString("Name"); JSONObject infoObj = jsonObject.getJSONObject("Info"); System.out.println("name_method: "+name_method); switch (name_method) { case "LOGIN"://注冊 result = login(infoObj); break; default: break; } return result; } /** * * @param infoObj * @return */ private String login(JSONObject infoObj){ String result = ""; //解析信息字段 String userName = infoObj.getString("userName"); String password = infoObj.getString("password"); String accessTime = infoObj.getString("accessTime");//Info JSONObject info = new JSONObject(); info.put("result", "Succ"); info.put("accessType", "3"); info.put("operator", "0"); //DeviceList JSONArray deviceIDList = new JSONArray(); JSONObject Id1 = new JSONObject(); Id1.put("ID","000001"); JSONObject Id2 = new JSONObject(); Id2.put("ID","000002"); deviceIDList.add(Id1); deviceIDList.add(Id2); info.put("deviceIDList", deviceIDList); //合並 JSONObject response = new JSONObject(); response.put("Name","LOGIN_ACK"); response.put("Info", info); JSONObject resultObj = new JSONObject(); resultObj.put("Response", response); String jsonStr = resultObj.toString(); //result = XmlJsonUtil.json2xml(jsonStr); result = jsonStr; System.out.print("result: "+result); return result; } }
好了,接下來是客戶端:
在微信小程序的js中通過如下代碼調用:
var loginJsonStr = ''; //method中設置你想調用的方法名 var method = 'invoke'; //wsdlurl中設置需要訪問的webservice的url地址 var wsdlurl = 'https://(域名)/(項目名)/services/ILockService?wsdl'; var targetNamespace = '(命名空間,可以去網頁輸入wsdlurl中查找)'; //datacopy中拼字符串,即http傳輸中的soap信息 var datacopy = '<?xml version="1.0" encoding="utf-8"?>'; datacopy += '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="(命名空間)>'; datacopy += '<soapenv:Header/>'; datacopy += '<soapenv:Body>'; //接着拼你要訪問的方法名、參數名和你傳遞的實參值,比如我要訪問的方法是invoke(String arg0) //而我的實際調用是invoke('libsys',2),所以拼字符串如下 datacopy += '<ser:invoke>'; datacopy += '<xmlData>' + loginJsonStr+'</xmlData>'; datacopy += '</ser:invoke>'; datacopy += '</soapenv:Body>'; datacopy += '</soapenv:Envelope>'; wx.request({ url: wsdlurl, data: datacopy, method: 'POST', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT header: { 'content-type': 'text/xml;', 'SOAPAction': targetNamespace + method, }, // 設置請求的 header success: function (res) { // success var resData = res.data; console.log("success: "+resData); }, fail: function (res) { console.log("fail: " + res.data) } })
