Javascript Can'；t注册我的React本机应用程序-我的API有问题（可能？）

我正在尝试构建react本机应用程序，但似乎无法登录。当我尝试时，我得到了一个

“注册错误-出现问题”一般信息

我认为我的API不起作用，当我在postman上试用时，我得到了一个

404信息

URL应该很好，所以我不确定它是否与API后端中的设置有关，或者可能我正在以某种方式修改我的参数

以下是我的api.js代码：

//const BASE_URL = "http://{ip address}:5000";
const BASE_URL = 'https://neighbor-hood.herokuapp.com';

export const api = async (url, method, body = null, headers = {}) => {

try {
  const endPoint = BASE_URL.concat(url);
  const reqBody = body ? JSON.stringify(body) : null;


  const fetchParams = {method, headers};

  if((method === "POST" || method === "PUT") && !reqBody) {
      throw new Error("Request body required");
  }
  if(reqBody) {
      fetchParams.headers["Content-type"] = "application/json";
      fetchParams.body = reqBody;
  }
  const fetchResponse = await fetch(endPoint, fetchParams);

  let text = ''
  try{
    console.log("fetchResponse ", fetchResponse)
    text = await fetchResponse.text()
  } catch (err){
    console.log("Exception in turning text from response err", err)
  }

  return fetchResponse;
} catch (e) {
  console.log("Exception ", e)
  return e;
}
}

以下是导入api的my actions.js文件：

import {api} from "../service/api";

export const createNewUser = (payload) => {
return async (dispatch) => {

    try {
      dispatch({
        type: "CREATE_USER_LOADING"
      });

      const response = await api("/user/create", "POST", payload); 

      if(response.success) {
        dispatch({
            type: "CREAT_USER_SUCCESS"
        });
        dispatch({
            type: "AUTH_USER_SUCCESS",
            token: response.token
        });
        dispatch({
            type: "GET_USER_SUCCESS",
            payload: response.responseBody
        });

        return response;
      } else {
        throw response;
      }

    } catch (error) {
        dispatch({
            type: "CREAT_USER_FAIL",
            payload: error.responseBody
        });
        return error;
    }
  }
}

export const loginUser = (payload) => {
  return async (dispatch) => {

    try {
      dispatch({
        type: "LOGIN_USER_LOADING"
      });

      const response = await api("/user/login", "POST", payload);

      if(response.success) {
        dispatch({
            type: "LOGIN_USER_SUCCESS",
        });
        dispatch({
            type: "AUTH_USER_SUCCESS",
            token: response.token
        });
        dispatch({
            type: "GET_USER_SUCCESS",
            payload: response.responseBody
        });
        return response;
      } else {
        throw response;
      }

    } catch (error) {
        dispatch({
            type: "LOGIN_USER_FAIL",
            payload: error.responseBody
        });
        return error;
    }
  }
}

export const logoutUser = () => {
  return async (dispatch, getState) => {
    const state = getState();
    try {
        const {authReducer: {authData: {token}}} = state;
        console.log(token);

        const response = await api("/user/logout", "DELETE", payload);
        console.log(response);
        dispatch({
            type: "USER_LOGGED_OUT_SUCCESS"
        });
    } catch (e) {
        console.log(e);
    }
  }
}

这是我在控制台中得到的结果：

"_data": Object {
  "blobId": "DC45F3C7-FB3E-4120-8B92-0AC798181824",

我认为我的API不起作用，当我在postman上试用时，我收到一条404消息

这说明您有一些后端错误，因为即使您尝试从邮递员处获得404的

错误，这是来自后端的错误
