我正在使用适用于 JavaScript 的 Google Drive Picker API，并希望检索与 Google Drive 生成的 URL 相对的文档缩略图。
下面是谷歌检索文档，并在其中产生了一个url:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>Google Picker Example</title>
<script type="text/javascript">
// The Browser API key obtained from the Google Developers Console.
var developerKey = 'xxxxxxxYYYYYYYY-12345678';
// The Client ID obtained from the Google Developers Console. Replace with your own Client ID.
var clientId = "1234567890-abcdefghijklmnopqrstuvwxyz.apps.googleusercontent.com"
// Scope to use to access user's photos.
var scope = ['https://www.googleapis.com/auth/photos'];
var pickerApiLoaded = false;
var oauthToken;
// Use the API Loader script to load google.picker and gapi.auth.
function onApiLoad() {
gapi.load('auth', {'callback': onAuthApiLoad});
gapi.load('picker', {'callback': onPickerApiLoad});
}
function onAuthApiLoad() {
window.gapi.auth.authorize(
{
'client_id': clientId,
'scope': scope,
'immediate': false
},
handleAuthResult);
}
function onPickerApiLoad() {
pickerApiLoaded = true;
createPicker();
}
function handleAuthResult(authResult) {
if (authResult && !authResult.error) {
oauthToken = authResult.access_token;
createPicker();
}
}
// Create and render a Picker object for picking user Photos.
function createPicker() {
if (pickerApiLoaded && oauthToken) {
var picker = new google.picker.PickerBuilder().
addView(google.picker.ViewId.PHOTOS).
setOAuthToken(oauthToken).
setDeveloperKey(developerKey).
setCallback(pickerCallback).
build();
picker.setVisible(true);
}
}
// A simple callback implementation.
function pickerCallback(data) {
var url = 'nothing';
if (data[google.picker.Response.ACTION] == google.picker.Action.PICKED) {
var doc = data[google.picker.Response.DOCUMENTS][0];
url = doc[google.picker.Document.URL];
}
var message = 'You picked: ' + url;
document.getElementById('result').innerHTML = message;
}
</script>
</head>
<body>
<div id="result"></div>
<!-- The Google API Loader script. -->
<script type="text/javascript" src="https://apis.google.com/js/api.js?onload=onApiLoad"></script>
</body>
</html>
简而言之，我想要一个缩略图而不是 URL，因为我想向用户显示缩略图，点击它会将他们带到相应的文档而不是 url
最佳答案
看https://developers.google.com/picker/docs/reference并向下滚动到靠近底部的文档。您将看到 Document 对象有一个属性 THUMBNAILS。
关于javascript - 从 Google Drive 检索缩略图，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28162855/
