Goal:
Use Axios with put and post method from react TS to Backend WebApi c#.
Problem:
The code doesn't work in relation to CORS.
What part from the backend source code am I missing in order to make backend to retrieve data that is PUT or POST?
Thank you!
React TS
import React from 'react'; import logo from './logo.svg'; import './App.css'; import axios from 'axios';
function App() {
const get = () => {
axios.get("https://localhost:7177/WeatherForecast/GetTestData")
.then(
response => console.log(response)
);
};
const update = () => { const data = { CandyNumber: Number("1"), Name: "asdf" };
axios.put("https://localhost:7177/WeatherForecast/UpdateTestData", data)
.then(
response => console.log(response)
);
};
const add = () => { const data = { CandyNumber: Number("1"), content: "asdf" };
axios.post("https://localhost:7177/WeatherForecast/AddTestData", data)
.then(
response => console.log(response)
);
};
return ( Get Add Uppdate ); }
export default App;
