SpringSocial业务系统与社交网站的绑定与解绑

时间：2022-01-18 19:02:50

SpringSocial提供了了以下三个服务，我们要做的仅仅是调用它们的服务，但是SpringSocial仅仅只提供了数据，没有提供视图

⒈拿到所有社交网站与业务系统的绑定信息

　　SpringSocial已经提供了相应的数据，但并没有提供视图，相关的代码写在ConnectController中，核心代码如下：

     @RequestMapping(

         method = {RequestMethod.GET}

     )

     public String connectionStatus(NativeWebRequest request, Model model) {

         this.setNoCache(request);

         this.processFlash(request, model);

         Map<String, List<Connection<?>>> connections = this.connectionRepository.findAllConnections();

         model.addAttribute("providerIds", this.connectionFactoryLocator.registeredProviderIds());

         model.addAttribute("connectionMap", connections);

         return this.connectView();

     }

　　这个方法的返回值是一个View，路径是connect/status，我们只需要实现这个视图就可以了。

 package cn.coreqi.social;

 import com.fasterxml.jackson.databind.ObjectMapper;

 import org.apache.commons.collections4.CollectionUtils;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.social.connect.Connection;

 import org.springframework.stereotype.Component;

 import org.springframework.web.servlet.view.AbstractView;

 import javax.servlet.http.HttpServletRequest;

 import javax.servlet.http.HttpServletResponse;

 import java.util.HashMap;

 import java.util.List;

 import java.util.Map;

 @Component("connect/status")

 public class CoreqiConnectionStatusView extends AbstractView {

     @Autowired

     private ObjectMapper objectMapper;

     @Override

     protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

         Map<String, List<Connection<?>>> connections = (Map<String, List<Connection<?>>>) map.get("connectionMap");

         Map<String,Boolean> result = new HashMap<>();

         for(String key:connections.keySet()){

             result.put(key, CollectionUtils.isNotEmpty(connections.get(key)));

         }

         httpServletResponse.setContentType("application/json;charset=UTF-8");

         httpServletResponse.getWriter().write(objectMapper.writeValueAsString(result));

     }

 }

⒉业务系统与社交网站绑定

 <!DOCTYPE html>

 <html lang="en">

 <head>

     <meta charset="UTF-8">

     <title>绑定</title>

 </head>

 <body>

     <h2>标准绑定页面</h2>

     <!--form 的action地址是固定的格式，前面是connect，后面是OAuth的providerId-->

     <form action="/connect/weixin" method="post">

         <button type="submit">绑定微信</button>

     </form>

 </body>

 </html>

绑定成功后跳转到connect/{providerId}Connected这个视图，上面的例子将会跳转到connect/weixinConnected这个视图上。

 package cn.coreqi.social;

 import org.springframework.stereotype.Component;

 import org.springframework.web.servlet.view.AbstractView;

 import javax.servlet.http.HttpServletRequest;

 import javax.servlet.http.HttpServletResponse;

 import java.util.Map;

 @Component("connect/weixinConnect,connect/weixinConnected")   //如果当前绑定成功的视图需要重用，请注释@Component注解

 //在配置类中以@Bean的形式注册当前类，并指定多个不同的name属性。

 public class CoreqiConnectionView extends AbstractView {

     @Override

     protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

         httpServletResponse.setContentType("text/html;charset=UTF-8");

         if(map.get("connection") == null){

             httpServletResponse.getWriter().write("<h3>解绑成功</h3>");

         }else{

             httpServletResponse.getWriter().write("<h3>绑定成功</h3>");

         }

     }

 }

⒊业务系统与社交网站解绑

 <!DOCTYPE html>

 <html lang="en">

 <head>

     <meta charset="UTF-8">

     <title>绑定</title>

 </head>

 <body>

     <h2>标准绑定页面</h2>

     <!--form 的action地址是固定的格式，前面是connect，后面是OAuth的providerId-->

     <!--解除绑定只需将post请求改为delete请求，当然，form表单是无法发送delete请求的，我只是告诉你-->

     <form action="/connect/weixin" method="delete">

         <button type="submit">绑定微信</button>

     </form>

 </body>

 </html>

解绑成功后跳转到connect/{providerId}Connect这个视图（相较于绑定，视图名去掉了ed而已），上面的例子将会跳转到connect/weixinConnect这个视图上。

 package cn.coreqi.social;

 import org.springframework.stereotype.Component;

 import org.springframework.web.servlet.view.AbstractView;

 import javax.servlet.http.HttpServletRequest;

 import javax.servlet.http.HttpServletResponse;

 import java.util.Map;

 @Component("connect/weixinConnect,connect/weixinConnected")   //如果当前绑定成功的视图需要重用，请注释@Component注解

 //在配置类中以@Bean的形式注册当前类，并指定多个不同的name属性。

 public class CoreqiConnectionView extends AbstractView {

     @Override

     protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

         httpServletResponse.setContentType("text/html;charset=UTF-8");

         if(map.get("connection") == null){

             httpServletResponse.getWriter().write("<h3>解绑成功</h3>");

         }else{

             httpServletResponse.getWriter().write("<h3>绑定成功</h3>");

         }

     }

 }
