react js, it does not return the token code-CodePudding

react js, it does not return the token code. In the "postman" it works okay, a method "POST" and in the body I pass in "raw" the following json {"username": "Emanuel Lemos", "password": "123213"}. But when I do it in react js it doesn't return that, what am I doing wrong? Thank you

    const apiLogin = "http://america-emer-webcore.dev.emergencias.com.ar/api/login"

// Llamado a la api para obtener token
export const apiCallToken = async () => {
  const res = await fetch(apiLogin, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      username: "Emanuel Lemos",
      password: "123213",
    }),
  })
  const llave = await res.json()  // eslint-disable-next-line no-console
  console.log(llave)

  return llave

CodePudding user response：

could you post your React component code? Without it it's hard to understand what's the issue there. The apiCallToken function looks fine.

Do you see any CORS issues? Maybe enable cors on the backend side. If you don't have access to the backend side and think the backend supports CORS, try a proxy on the frontend.

See this link to set up a proxy in react.
