在反应中从 Api 获取数据

Question

I want to fetch the data from this api (refer the screenshots) in reactjs using fetch function..I tried different ways but none of them is working

I am doing this way

useEffect(() => {
    // POST request using fetch inside useEffect React hook
    const requestOptions = {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ "firebase_id":"fonnnnjnvQXzyOcXK5kW88PM8jnjnhnhb1"})
    };
    fetch('demo.revon.com/audi/zero/li', requestOptions)
        .then(response => response.json())
        .then(data =>  console.log(data));                 

Answer 1

You should try to call your API without https://localhost:3000 in front of your API link.

You forgot to put HTTP or HTTPS so it consider a subfolder of localhost:3000.

You must do something like that: (or http if not https)

fetch('https://demo.revon.com/audi/zero/li', requestOptions)
        .then(response => response.json())
        .then(data =>  console.log(data));

Answer 2

You'll need to mention https:// in the fetch url

Answer 3

requestOptions is not the issue here!

You are OBVIOUSLY hitting the localhost domain, not demo.revon .
Insert the full URL: https://demo.revon.com/audi/zero/li
