Question

我正在尝试在Web应用程序中创建购物车，该购物车中的重定向是根据添加，更新的产品在spring控制器中完成的。我编写了调用@RequestMapping("/add/{productId}/product")的axios get请求，该请求重定向到另一个请求映射，并且结果就是回报。我将结果放入地图中，并且可以在控制台上看到地图结果。但是我无法在redux商店中获得结果。

这是重定向链接show?result=updated。会引发404错误。

这是我的Axiso获取请求。

export const getCart = (pt_id) => async dispatch => {
  const res = await axios.get(`http://localhost:8080/cart/add/${pt_id}/product`);

  dispatch({
    type: GET_CART,
    payload: res.data
  });
};

在弹簧控制器中

@RequestMapping("/{cartLineId}/update")
public String udpateCartLine(@PathVariable int cartLineId, @RequestParam int count) {
    String response = cartService.manageCartLine(cartLineId, count);        
    return "redirect:/cart/show?"+response;     
}

@RequestMapping("/add/{productId}/product")
public String addCartLine(@PathVariable int productId) {
    String response = cartService.addCartLine(productId);
    return "redirect:/cart/show?"+response;
}


@RequestMapping("/show")
public Map<String, Object> showCart(@RequestParam(name = "result", required = false) String result) {

    Map<String, Object> cartMap = new HashMap<String, Object>();
    cartMap.put("title", "Shopping Cart");

    if(result!=null) {
        switch(result) {

            case "added":
                cartMap.put("message", "Product has been successfully added inside cart!");
                cartService.validateCartLine();
                break;

            case "unavailable":
                cartMap.put("message", "Product quantity is not available!");
                break;

            case "updated":
                cartMap.put("message", "Cart has been updated successfully!");
                cartService.validateCartLine();
                break;
        }
    }
    else {
        String response = cartService.validateCartLine();
        if(response.equals("result=modified")) {
            cartMap.put("message", "One or more items inside cart has been modified!");
        }
    }

    cartMap.put("cartLines", cartService.getCartLines());
    return cartMap; 
}

如果我打印出cartMap，我可以在控制台上看到结果。

这是网络日志

我在这里做错了什么？

如何处理axios和spring controller中的重定向？
