how can i use a value from outside in axios-CodePudding

How can I use the value returned in the export function in another component? I have a string value (url) in export function header.js

 export default function Header() {
        const [countries] = useState([
            { code: 'tr', title: 'Tr' },
            { code: 'gb', title: 'En' },
        ]);
        const [toggleContents, setToggleContents] = useState(<MdLanguage />);
        const [selectedCountry, setSelectedCountry] = useState();
    
        if (selectedCountry === "tr") {
            getLang("tr");
        }
        else if (selectedCountry === "en") {
            getLang("en");
        }
        else {
            getLang("en");
        }

api.js (my databse address localhost:8080/product/en or http://localhost:8080/product/tr )

export const function getLang = async (param) => {
    const url = ProductUrl   param;
        return url;
        };

I need to call this url in axios in useeffect in other component.

navbar.js (navbars menu turkish or english so if dropdown select tr , url tr // if dropdown select english , url en)

  useEffect(() => {
    axios
      .get(how?)
      .then(response => setData(response.data))
      .catch(error => console.log({ error }));
  }, []);

thank you.

CodePudding user response：

You need to import it in the component where you want to use it as ---> import {a} from "filedirectory" then use it in the component by calling that function as

const urlValue = a()

CodePudding user response：

useEffect(() => {
const url = a(params);
    axios
      .get(url)
      .then(response => setData(response.data))
      .catch(error => console.log({ error }));
  }, []);

CodePudding user response：

// getUrl.js
export const getUrl = (params) => {
  return ProductUrl   params;
}
// or export default
// export default function getUrl(params) {
//   return ProductUrl   params
// }

Import it into where you want

import { getUrl } from './your-path'
// or import default
// import getUrl from './your-path'

React.useEffect(() => {
  const url = getUrl(params)
  const fetchData = async () => {
    try {
      const response = await axios.get(url)
      // do something with reponse
    } catch (error) {
      // handle err
    }
  }
  fetchData()

}, [params])
