Node.js Axios请求不使用React Native+；Nodejs

尝试使SignIn函数与NodeJS后端一起工作。单击Signin按钮时，什么也没有发生，控制台上出现一个错误，上面写着--POSThttp://IP_Address:3000/signin 网络：：错误连接被拒绝

import api from "../services/api";

const signIn =
  (dispatch) =>
  async ({ email, password }) => {
    try {
      const response = await api.post("/signin", { email, password });
      await AsyncStorage.setItem("token", response.data.token);
      dispatch({ type: "sign_up_in", payload: response.data.token });
    } catch (error) {
      console.log(error);
      dispatch({
        type: "add_error",
        payload: "Something went wrong with Sign In",
      });
    }
  };

Here is what is residing inside the services/api.js
import axios from "axios";
import AsyncStorage from "@react-native-async-storage/async-storage";

axios.defaults.baseURL = "http://IP_Address:3000";

const instance = axios.create();

instance.interceptors.request.use(
  async (config) => {
    const token = await AsyncStorage.getItem("token");
    if (token) {
      config.headers.Authorization = `Bearer ${token}`;
    }
    return config;
  },
  (err) => {
    return Promise.reject(err);
  }
);

export default instance;

您是否验证了您的API是否已启动并在端口3000上运行？是的，我已在CMD上运行节点服务器，而在VS代码终端上运行客户端（react native）。因此，您的API基本url“http://IP_Address:3000“是

”http://localhost:3000“

或

”http://127.0.0.1:3000“

对吗？
