我试图使用 Google App Script。我的第一次尝试涉及打开文件选择器并从我的 Google 云端硬盘中选择文件的功能。为此，我阅读了 official documentation我尝试去实现它。所以我编写了以下应用程序:
代码.gs
function doGet() {
return HtmlService
/*.createTemplateFromFile('index.html')
.evaluate();*/
.createHtmlOutputFromFile('index.html');
}
index.html
<!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 API Console.
// Replace with your own Browser API key, or your own key.
var developerKey = "{{developer-key}}";
// The Client ID obtained from the Google API Console. Replace with your own Client ID.
var clientId = "{{client-id}}"
// Replace with your own project number from console.developers.google.com.
// See "Project number" under "IAM & Admin" > "Settings"
var appId = "{{project-number}}";
// Scope to use to access user's Drive items.
var scope = ['https://www.googleapis.com/auth/drive'];
var pickerApiLoaded = false;
var oauthToken;
// Use the Google API Loader script to load the google.picker script.
function loadPicker() {
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 searching images.
function createPicker() {
if (pickerApiLoaded && oauthToken) {
var view = new google.picker.View(google.picker.ViewId.DOCS);
view.setMimeTypes("image/png,image/jpeg,image/jpg");
var picker = new google.picker.PickerBuilder()
.enableFeature(google.picker.Feature.NAV_HIDDEN)
.enableFeature(google.picker.Feature.MULTISELECT_ENABLED)
.setAppId(appId)
.setOAuthToken(oauthToken)
.addView(view)
.addView(new google.picker.DocsUploadView())
.setDeveloperKey(developerKey)
.setCallback(pickerCallback)
.build();
picker.setVisible(true);
}
}
// A simple callback implementation.
function pickerCallback(data) {
if (data.action == google.picker.Action.PICKED) {
var fileId = data.docs[0].id;
alert('The user selected: ' + fileId);
}
}
</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=loadPicker"></script>
</body>
</html>
当我尝试执行代码时，在授权阶段之后，我收到一个空白屏幕和一个空白对话框，并显示错误:无法执行“postMessage”。怎么了？谢谢
最佳答案
问题/解决方案:
您正在 iframe 中工作，其中的内容是从不同的来源提供的。您应该在选择器构建器上使用 setOrigin。
片段:
var picker = new google.picker.PickerBuilder()
//...
.setOrigin(google.script.host.origin)
