当我运行此文件时,我什么也没得到。如果我在最后运行console.log(getInfo());
,我会得到Promise <pending>
。请帮忙。
function getInfo(){
var url = `https://api.nutritionix.com/v1_1/search/cheddar%20cheese?fields=item_name%2Citem_id%2Cbrand_name%2Cnf_calories%2Cnf_total_fat&appId=${apiId}&appKey=${apiKey}`;
return(
fetch(url)
.then(data=>{
return JSON.parse(data);
})
);
}
getInfo().then(result =>{
console.log(result);
最佳答案
这不是您使用fetch API的方式。像这样使用response.json()
(因为我不知道apiId
和apiKey
,所以会记录错误):
function getInfo(){
var apiId = 1;
var apiKey = 1;
var url = `https://api.nutritionix.com/v1_1/search/cheddar%20cheese?fields=item_name%2Citem_id%2Cbrand_name%2Cnf_calories%2Cnf_total_fat&appId=${apiId}&appKey=${apiKey}`;
return fetch(url).then(response => response.json());
}
getInfo().then(data => console.log(data));
