goEasy的简单使用

案列介绍：

1. 前端配置goEasy（这里是配置vue项目）
   在main.js中配置一个全局参数
   因为前端只是为了接收消息，不需要推送消失所以我配置appkey是BS开头的那个

// //初始化
const goEasy = GoEasy.getInstance({ 
   
  host: "hangzhou.goeasy.io", //若是新加坡区域：singapore.goeasy.io
  appkey: "BS-********",
  modules: ['pubsub'] //根据需要，传入‘pubsub’或'im’，或数组方式同时传入
});

Vue.prototype.goEasy = goEasy;
Vue.prototype.pubsub = goEasy.pubsub;

使用示例

export default { 
   
    beforeMount() { 
   
      var self = this;
      //连接GoEasy
      this.goEasy.connect({ 
   
        data: { 
   },
        onProgress: function(attempts) { 
   
           console.log("GoEasy is connecting" + attempts);
          // self.unshiftMessage("GoEasy is connecting" + attempts);
        },
        onSuccess: function() { 
   
          // self.unshiftMessage("GoEasy connect successfully.");
           console.log("GoEasy connect successfully.");
        },
        onFailed: function(error) { 
   
           console.log("Failed to connect GoEasy, code:" + error.code + ",error:" + error.content);
          // self.unshiftMessage("Failed to connect GoEasy, code:" + error.code + ",error:" + error.content);
        }
      });

      //接收消息
      this.pubsub.subscribe({ 
   
        channel: "WXPay",
        onMessage: function(message) { 
   
          // self.unshiftMessage(message.content);
          console.log("微信回调成功:"+message.content);
          if(message.content=="支付成功"){ 
   
            self.QRcodeUrl=imgUrl
          }
        },
        onSuccess: function() { 
   
          // self.unshiftMessage('订阅成功.');
          console.log("订阅成功");
        },
        onFailed: function(error) { 
   
          // self.unshiftMessage("订阅失败，错误编码：" + error.code + " 错误信息：" + error.content);
          console.log("订阅失败，错误编码："+error.code + " 错误信息：" + error.content);
        }
      });
    },
    components: { 
   
      Pagination
    },
    data() { 
   
      return { 
   
        imgUrl,
        QRcodeUrl: '',
        dialogVisible: false,
        list: null,
        listLoading: true,
        total: 0,
        goodsId: '',
        listQuery: { 
   
          page: 1,
          limit: 10
        }
      }
    },
    created() { 
   
      this.fetchData()
    },
    methods: { 
   
      handleClose(done) { 
   
        this.$confirm('确认关闭？')
          .then(_ => { 
   
            done();
          })
          .catch(_ => { 
   });
      },
      fetchData() { 
   
        var vm = this;
        this.axios({ 
   
          method: 'post',
          url: 'http://localhost:7002/llcItems/page',
          data: { 
   
            "goodsId": vm.goodsId.trim(),
            "page": vm.listQuery.page,
            "size": vm.listQuery.limit
          }
        }).then(function(response) { 
   
          console.log(response.data.data.list),
            vm.list = response.data.data.list,
            vm.total = response.data.data.total,
            vm.listLoading = false
        })
      },
      serchMsg() { 
   
        this.listQuery.page = 1
        this.fetchData()
      },
      updateMsg(id) { 
   
        this.$router.push("/editproduct/" + id)
      },
      addMsg(id) { 
   
        this.$router.push("/addproduct")
      },
      // 获取二维码
      getQRcode(id) { 
   
        var vm = this;
        this.axios({ 
   
          method: 'get',
          url: 'http://localhost:7002/wx/wxpayOrder?goodsId=' + id,
          responseType: 'blob', // 重点
        }).then(res => { 
   
          // res.data是返回的文档流
          const blob = new Blob([res.data]);
          const url = window.URL.createObjectURL(blob);
          vm.QRcodeUrl = url;
          vm.dialogVisible = true
        })
      },
      deleteMsg(id) { 
   
        var vm = this;
        this.axios({ 
   
          method: 'delete',
          url: 'http://localhost:7002/llcItems/delete?goodsId=' + id,
        }).then(function(res) { 
   
          if (res.data.data == true) { 
   
            vm.$message({ 
   
              message: '删除成功',
              type: 'success'
            });
            vm.fetchData();
          }
        }).catch(function(error) { 
   
          vm.$message.error('删除失败');
        })
      }

    }
  }

2. 后端推给前端消息（就是支付成功微信回调的时候将消息推送给前端）
   注意这里的channl是唯一通道所以请自行考虑，还是我配置的appkey是BC开头那个因为需要接受和推送消息。

@PostMapping("/wxpay")
    @ApiOperation(value = "微信回调地址")
    public Result<String> getPage(HttpServletRequest httpServletRequest) throws IOException { 
   
        Map<String, String> map = WXutil.parseParam(httpServletRequest);
        System.out.println("参数解析:" + map);
        PayCallBackInfo payCallBackInfo = this.checkSign(map, MCH_KEY);
        if (null != payCallBackInfo && PayCallBackInfo.PAY_SUCCESS == payCallBackInfo.getStatus()) { 
   
            applicationContext.publishEvent(new PaySuccessEvent(this, payCallBackInfo));
        } else { 
   
            applicationContext.publishEvent(new PayFailEvent(this, payCallBackInfo));
        }
        Document responseDocument = DocumentHelper.createDocument();
        Element responseRootElement = responseDocument.addElement("xml");
        responseRootElement.addElement("return_code").addCDATA("SUCCESS");
        responseRootElement.addElement("return_msg").addCDATA("OK");
        System.out.println("微信响应参数:" + responseDocument.asXML());
        //更新订单状态
        ThreadUtil.execAsync(()->llcOrderService.update(map.get("out_trade_no")));
        //使用goEasy将支付成功的消息推送给前端
        GoEasy goEasy=new GoEasy("http://rest-hangzhou.goeasy.io","BC-********");
        goEasy.publish("WXPay","支付成功");
        return new Result<>(responseDocument.asXML());
    }
