请求回调callback

直接在dispatch中用callback

 dispatch({ 
      type: 'TASK_ADD',
      AreaName:this.state.taskDistrict,
      CarID:this.state.taskCar,
      PointStart:this.state.startStation,
      PointEnd:this.state.endStation,
      CreatedBy:this.props.account.username,
      callback: (res) => {
        if (res) {
          if(res.Status === 1){
            message.success(res.Message+'任务创建成功!');
          }else{
            message.error('任务创建失败!');
          }
          console.log(res);// 请求完成后返回的结果
        }
      }
    });

在另外的saga中酱紫写

 const data = yield call(request, uri, {
      method: 'POST',
      body:{
        AreaName,
        CarID,
        PointStart,
        PointEnd,
        CreatedBy
      }
    });
    console.log(data);
    if(callback) callback(data);
