【问题描述】:
“Kanye West Amazing”的 youtube 搜索查询应返回多个 youtube 链接。但是,通过 api 的 youtube 查询返回 null(来自 console.log):
<!doctype html>
<html>
<head>
<title>Vidify</title>
</head>
<body>
<!--Add a button for the user to click to initiate auth sequence -->
<button id="authorize-button" style="visibility: hidden">Authorize</button>
<script type="text/javascript">
var clientId = '591751286145-ktngvf2s76uiuuevan6mo1fft0kchl8l.apps.googleusercontent.com';
var apiKey = 'AIzaSyB0mteDV5vDKFR-iAv4Fx4OC2gp1Yhqe9U';
var scopes = 'https://www.googleapis.com/auth/youtube';
function handleClientLoad() {
console.log('API key provided - authorizing client...');
// Step 2: Reference the API key
gapi.client.setApiKey(apiKey);
gapi.auth.init(checkAuth);
}
function checkAuth() {
console.log('entered checkAuth - authorizing...');
setTimeout(function() {
console.log("requesting auth");
gapi.auth.authorize({
client_id: clientId,
scope: scopes,
response_type:'token',
immediate: true
}, handleAuthResult);
}, 100);
}
function handleAuthResult(authResult) {
console.log('received authResult');
var authorizeButton = document.getElementById('authorize-button');
if (authResult && !authResult.error) {
console.log("auth. successful");
authorizeButton.style.visibility = 'hidden';
makeApiCall();
} else {
console.log('auth failed.');
authorizeButton.style.visibility = '';
authorizeButton.onclick = handleAuthClick;
}
}
function handleAuthClick(event) {
// Step 3: get authorization to use private data
console.log('retry');
gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: false}, handleAuthResult);
return false;
}
// Load the API and make an API call. Display the results on the screen.
function makeApiCall() {
console.log("loaded client");
gapi.client.setApiKey(apiKey);
// Step 4: Load the Google+ API
gapi.client.load('youtube', 'v3', function() {
console.log('youtube API loaded...');
// Step 5: Assemble the API request
var qVar = "Kanye West Amazing"
// changed. added: type
var request = gapi.client.youtube.search.list({
type: 'video',
part: 'id',
q: qVar
});
// Step 6: Execute the API request
request.execute(function(resp) {
console.log(resp);
var vid = document.createElement('vid');
vid.value = resp.items[0].id.videoId;
console.log(vid.value);
var youtube_url = "http://www.youtube.com/watch?v=";
youtube_url += vid.value;
youtube_url += "&rel=0";
window.open(youtube_url);
});
});
}

所以我实际上是在尝试从 spotify 桌面应用程序中运行它。 spotify 应用程序系统允许我从“spotify 浏览器”中加载 index.html。以下是我现在遇到的错误:
未捕获的类型错误:无法调用未定义的方法“setApiKey”
