Reactjs reducer redux thunk未调用reducer

下面的代码分派create_事件，然后调用addFlashMessage操作

export const createEvent = event => {
  return dispatch => {
    dispatch({
      type: "CREATE_EVENT",
      payload: {
        event
      }
    });
    addFlashMessage("Event has been created");
  };
};

addFlashMessage在操作时被调用
但是不调用添加FLASH消息

export const addFlashMessage = message => {
  console.log("action is invoked");
  return dispatch => {
    dispatch({
      type: "ADD_FLASH_MESSAGE",
      payload: {
        message
      }
    });
  };
};

这是从来没有被称为

 case "ADD_FLASH_MESSAGE":
            console.log("action called");

您需要

dispatch

调用

addFlashMessage

操作，如下所示

dispatch({type: "ADD_FLASH_MESSAGE",payload:"Event has been created"});

您的代码应该如下所示

export const createEvent = event => {
  return dispatch => {
    dispatch({
      type: "CREATE_EVENT",
      payload: {
        event
      }
    });
   dispatch({type: "ADD_FLASH_MESSAGE",payload:"Event has been created"});
  };
};

    });
   dispatch({type: "ADD_FLASH_MESSAGE",payload:"Event has been created"});
  };
};

不只是从

createEvent

调用另一个函数，您需要

dispatch

来触发

redux thunk

函数

这是正确的

export const createEvent = event => {
  return dispatch => {
    dispatch({
      type: "CREATE_EVENT",
      payload: {
        event
      }
    });
    dispatch(addFlashMessage("Event has been created"));
  };
};

    });
    dispatch(addFlashMessage("Event has been created"));
  };
};

但当addFlashMessage（“事件已创建”）时，该功能才起作用；调用时，它会导致reducer返回分派方法，说明为什么没有发生任何clueconsole.log（“调用操作”）；i、 调用e action，但不调用reducer，因为它是JavaScript。。你在做什么，调用一个函数，它就会工作。但redux不会以这种方式工作，除非addFlashMessage（“事件已创建”）；调用时，它会导致reducer返回分派方法，说明为什么没有发生任何clueconsole.log（“调用操作”）；i、 调用e action，但不调用reducer，因为它是JavaScript。。你在做什么，调用一个函数，它就会工作。但redux不会以这种方式工作
