我是 React Native 和 Axios 的新手，我正在尝试构建一个身份验证系统，我的 API（在 Laravel 中创建）在 Postman 中运行良好，当我来测试整个应用程序并尝试登录时，出现此错误：

我正在使用我的 Android 手机进行测试，这可能是代码：

axios.defaults.baseURL = 'http://localhost:8000';

export const AuthContext = React.createContext({});

export const AuthProvider = ({ children }) => {

    const [user, setUser] = useState(null);
    const [error, setError] = useState(null);

    return (
        <AuthContext.Provider 
            value={{
                user,
                setUser,
                error,
                setError,
                login: (email, password) => {
                    axios.post('/api/sanctum/token', {
                        email,
                        password,
                        device_name: 'mobile',
                    })
                    .then(response => {
                        const userResponse = {
                            email: response.data.user.email,
                            token: response.data.token,
                        };
                        setUser(userResponse);
                        SecureStore.setItemAsync('user', JSON.stringify(userResponse));
                    })
                    .catch(error => {
                        // const key = Object.keys(error.response.data.errors)[0];
                        // setError(error.response.data.errors[key][0]);
                        console.log(error);
                    });
                },
                logout: () => {

                    axios.defaults.headers.common['Authorization'] = `Bearer ${user.token}`;

                    axios.post('/api/logout')
                    .then(response => {
                        setUser(null);
                        SecureStore.deleteItemAsync('user');
                    })
                    .catch(error => {
                        console.log(error.response);
                    });

                }
            }}>
            {children}
        </AuthContext.Provider>
    );
}
