从GET解析Json数据时出现问题

fetch('https://example.com/api/data', {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json'
    }
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

fetch('https://example.com/api/data')
.then(response => {
    if (!response.ok) {
        throw new Error('Network response was not ok ' + response.statusText);
    }
    return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('There has been a problem with your fetch operation:', error));

fetch('https://api.example.com/data')
.then(response => {
    if (!response.ok) {
        throw new Error('Network response was not ok');
    }
    return response.json();
})
.then(data => {
    console.log('Success:', data);
})
.catch((error) => {
    console.error('Error:', error);
});
