[英]Why my api request returns an empty object?
So I use Google Books API in my application, and i make a request do display data in console, but for some reason it returns an empty object, instead of array of books.所以我在我的应用程序中使用了 Google Books API,并且我发出一个请求在控制台中显示数据,但由于某种原因它返回一个空对象,而不是书籍数组。
Javascript code: Javascript代码:
const API_KEY = 'key=<API-KEY>';
const BASE_URL = 'https://www.googleapis.com/books/v1/';
const API_URL = BASE_URL + 'volumes?q=subject:fiction' + API_KEY;
getBooks(API_URL);
function getBooks(url){
fetch(url).then(res => res.json()).then(data =>{
console.log(data);
})
}
Console in browser:浏览器中的控制台:
Edit: So I added '&' in the url and it changed, but now it gives 403 error:编辑:所以我在 url 中添加了 '&' 并且它改变了,但现在它给出了 403 错误:
{
"error": {
"code": 403,
"message": "Requests from this Android client application \u003cempty\u003e are blocked.",
"errors": [
{
"message": "Requests from this Android client application \u003cempty\u003e are blocked.",
"domain": "global",
"reason": "forbidden"
}
],
"status": "PERMISSION_DENIED"
}
}
Maybe I got the wrong key?也许我拿错了钥匙? I got it from Google Books credentials, so I thought it should've worked.我是从 Google Books 凭据中获得的,所以我认为它应该有效。
You forgot the &
sign between the query params, so you need to change您忘记了查询参数之间的&
符号,因此您需要更改
const API_URL = BASE_URL + 'volumes?q=subject:fiction' + API_KEY;
to到
const API_URL = BASE_URL + 'volumes?q=subject:fiction&' + API_KEY;
And also revoke this API Key并且还撤销这个 API Key
您将密钥作为 q 值的一部分发送,因为您忘记了“&”。
const API_URL = BASE_URL + 'volumes?q=subject:fiction&' + API_KEY;
