在react native中，get请求不起作用。有人能帮助我吗？

export const getDashboardService = async (params, callback, errorCallback) => {
const url = ServerConstants.serviceMethods.baseUrl + params.userId;
try {
    let res = await axios.get(
        url,
        {
            headers: {
                ...ServerConstants.serviceHeaderParameters,
                Authorization: `Bearer ${params.token}`
            }
        }
    );
    console.log(res);
} catch (error) {
    console.log(error);
}
};
