原始关闭原因未得到解决
let city;
let c;
async function getCity() {
let apiKey = '9ddf7197ff9633535259c99aa0716c329981d1514f05e2e1e2015803';
let response = await fetch(`https://api.ipdata.co?api-key=${apiKey}`);
let data = await response.json();
city = data.city;
return city;
}
getCity().then(
function (value) {
c = value.city;
},
function (error) {
console.log(error)
}
);
console.log(c);
如何将值分配给全局变量,以便它可以在代码中的任何位置使用。当我尝试这个方法时,我从console.log得到了“未定义”作为我的解决方案。
我认为在调用函数 getCity()
时不需要等待
。我无法获得值,但我修复了错误。试试这个:
let city;
async function getCity() {
let apiKey = 'api_key';
let response = await fetch(`https://api.ipdata.co?api-key=${apiKey}`);
let data = await response.json();
city = data.city;
return city;
}
getCity().then(
function (value) {
console.log(value)
},
function (error) {
console.log(error)
}
);
