谷歌开发人员页面上给出的“按关键字搜索”的 javascript 示例不适合我。https://developers.google.com/youtube/v3/code_samples/javascript https://developers.google.com/youtube/v3/code_samples/javascript当我运行代码时，我得到一个禁用的搜索框，里面有“猫”。此外，该示例没有解释如何写入 API 密钥（而不是客户端 ID）。它说这是可能的，但没有给出如何做到这一点的具体示例。有人能指出这段代码哪里出了问题吗？两个.js文件和html的代码如下：
auth.js 文件：
// The client ID is obtained from the Google Developers Console
// at https://console.developers.google.com/.
// If you run this code from a server other than http://localhost,
// you need to register your own client ID.
var OAUTH2_CLIENT_ID = '__YOUR_CLIENT_ID__';
var OAUTH2_SCOPES = [
'https://www.googleapis.com/auth/youtube'
];
// Upon loading, the Google APIs JS client automatically invokes this callback.
googleApiClientReady = function() {
gapi.auth.init(function() {
window.setTimeout(checkAuth, 1);
});
}
// Attempt the immediate OAuth 2.0 client flow as soon as the page loads.
// If the currently logged-in Google Account has previously authorized
// the client specified as the OAUTH2_CLIENT_ID, then the authorization
// succeeds with no user intervention. Otherwise, it fails and the
// user interface that prompts for authorization needs to display.
function checkAuth() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: true
}, handleAuthResult);
}
// Handle the result of a gapi.auth.authorize() call.
function handleAuthResult(authResult) {
if (authResult && !authResult.error) {
// Authorization was successful. Hide authorization prompts and show
// content that should be visible after authorization succeeds.
$('.pre-auth').hide();
$('.post-auth').show();
loadAPIClientInterfaces();
} else {
// Make the #login-link clickable. Attempt a non-immediate OAuth 2.0
// client flow. The current function is called when that flow completes.
$('#login-link').click(function() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: false
}, handleAuthResult);
});
}
}
// Load the client interfaces for the YouTube Analytics and Data APIs, which
// are required to use the Google APIs JS client. More info is available at
// http://code.google.com/p/google-api-javascript-client /wiki/GettingStarted#Loading_the_Client
function loadAPIClientInterfaces() {
gapi.client.load('youtube', 'v3', function() {
handleAPILoaded();
});
}
搜索.js 文件：
// After the API loads, call a function to enable the search box.
function handleAPILoaded() {
$('#search-button').attr('disabled', false);
}
// Search for a specified string.
function search() {
var q = $('#query').val();
var request = gapi.client.youtube.search.list({
q: q,
part: 'snippet'
});
request.execute(function(response) {
var str = JSON.stringify(response.result);
$('#search-container').html('<pre>' + str + '</pre>');
});
}
