product.jsx中的代码问题是我想更新数据，但它不适用于 firebase 并停止更新所有内容，所以我需要一些帮助

 export default function Product() {
  const [user,setUser]=useState({});
  const [file, setFile] = useState(null);
  const location = useLocation();
  const productId = location.pathname.split("/")[2];
  const [pStats, setPStats] = useState([]);

  const product = useSelector((state) =>
    state.product.products.find((product) => product._id === productId)
  );
 const handleChange =(e)=>{
    const value=e.target.value;
    setUser({
        ...user,
       [e.target.name]:value
    });
      };
      
      console.log(user)

  const dispatch = useDispatch();
 
  const handleclick=(id)=>{
    
    const fileName = new Date().getTime() + file.name;
    const storage = getStorage(app);
    const storageRef = ref(storage, fileName);
    const uploadTask = uploadBytesResumable(storageRef, file);

    uploadTask.on(
      "state_changed",
      (snapshot) => {
        // Observe state change events such as progress, pause, and resume
        // Get task progress, including the number of bytes uploaded and the total number of bytes to be uploaded
        const progress =
          (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
        console.log("Upload is " + progress + "% done");
        switch (snapshot.state) {
          case "paused":
            console.log("Upload is paused");
            break;
          case "running":
            console.log("Upload is running");
            break;
          default:
        }
      },
      (error) => {
        // Handle unsuccessful uploads
      },
      () => {
        // Handle successful uploads on complete
        // For instance, get the download URL: https://firebasestorage.googleapis.com/...
        getDownloadURL(uploadTask.snapshot.ref).then((downloadURL) => {
          const userr = { ...user, img: downloadURL};
          updateProduct(id,dispatch,userr)
        });
      }
    );
   
  }

  useEffect(() => {
    updateProduct(dispatch);
  }, [dispatch]);
  
  

  const MONTHS = useMemo(
    () => [
      "Jan",
      "Feb",
      "Mar",
      "Apr",
      "May",
      "Jun",
      "Jul",
      "Agu",
      "Sep",
      "Oct",
      "Nov",
      "Dec",
    ],
    []
  );

  useEffect(() => {
    const getStats = async () => {
      try {
        const res = await userRequest.get("order/income?pid=" + productId);
        const list = res.data.sort((a,b)=>{
            return a._id - b._id
        })
        list.map((item) =>
          setPStats((prev) => [
            ...prev,
            { name: MONTHS[item._id - 1], Sales: item.total },
          ])
        );
      } catch (err) {
        console.log(err);
      }
    };
    getStats();
  }, [productId, MONTHS]);

  return (

          </div>
        </form>
      </div>
    </div>
  );
}

api调用中的代码 (redux)

import {
  
  updateProductFailure,
  updateProductStart,
  updateProductSuccess,
  

} from "./productRedux";



export const updateProduct = async (id, product, dispatch) => {
  dispatch(updateProductStart());
  try {
    const res=await userRequest.patch(`/products/find/${id}`,product)
    
    dispatch(updateProductSuccess({ id, product }));
  } catch (err) {
    dispatch(updateProductFailure());
  }
};
}

产品 redux 中的代码

export const productSlice = createSlice({
  name: "product",
  initialState: {
    products: [],
    isFetching: false,
    error: false,
  },
  reducers: {
 updateProductStart: (state) => {
      state.isFetching = true;
      state.error = false;
    },
    updateProductSuccess: (state, action) => {
      state.isFetching = false;
      state.products[
        state.products.findIndex((item) => item._id === action.payload.id)
      ] = action.payload.product;
    },
    updateProductFailure: (state) => {
      state.isFetching = false;
      state.error = true;
    },
}

我想通过将数据从客户端发送到 api 我认为 updateProductsucess 函数中的问题

来更新我的产品

Answer 1

在您的 Product 函数中，您这样调用 updateProduct(id,dispatch,user)。

UpdateProduct 看起来像这样 export const updateProduct = async (id, product, dispatch) => {}

所以您将 dispatch 作为产品参数传入。将参数切换为相同的顺序然后你会很好。
