我正在尝试将 google OAuth api 与 Vue.js 结合使用。 我使用并修改了谷歌提供的示例代码。 但是当我点击“授权”按钮时,控制台返回:
Uncaught TypeError: Cannot read property 'init' of undefined
at Vue$3.initClient (vueAuth.js:24)
at Vue$3.boundFn [as initClient] (vue.js:196)
at Vue$3.handleClientLoad (vueAuth.js:20)
at boundFn (vue.js:196)
at invoker (vue.js:2006)
at HTMLButtonElement.fn._withTask.fn._withTask (vue.js:1804)
这是我的代码

spreadsheetId: '/* my sheet id */',

}
})
我想知道为什么 gapi.client.init 不可用。 我应该如何更改我的代码以启用 gapi?

以防其他人正在寻找这个。这就是我为我的添加到日历按钮所做的
public/index.html在头部添加脚本
<head>
...
<script async defer src="https://apis.google.com/js/api.js"></script>
...
</head>
模板:
<ion-button @click="addToCalendar(item)">
Add to Calendar <ion-icon :icon="calendarClearOutline"></ion-icon>
</ion-button>
脚本:
// after imports
var gapi = window.gapi;
var CLIENT_ID = "_YOUR_CLIENT_ID_";
var API_KEY = "_YOUR_API_KEY_";
var DISCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/calendar/v3/rest"];
var SCOPES = "https://www.googleapis.com/auth/calendar";
// in methods
addToCalendar(event) {
gapi.load("client:auth2", () => {
console.log("gapi loaded", gapi.client);
gapi.client.init({
apiKey: API_KEY,
clientId: CLIENT_ID,
discoveryDocs: DISCOVERY_DOCS,
scope: SCOPES
}).then(() => {
const gcEvent = {
"summary": event.eventName,
"location": event.venue,
"start": {
"dateTime": moment(event.start).utc().format("YYYY-MM-DDTHH:mm:ss.SSS[Z]"),
"timeZone": "Africa/Johannesburg"
},
"end": {
"dateTime": moment(event.end).utc().format("YYYY-MM-DDTHH:mm:ss.SSS[Z]"),
"timeZone": "Africa/Johannesburg"
},
"reminders": {
"useDefault": false,
"overrides": [
{"method": "email", "minutes": 24 * 60},
{"method": "popup", "minutes": 10}
]
}
};
var request = gapi.client.calendar.events.insert({
'calendarId': 'primary',
'resource': gcEvent,
});
// window object is undefined inside `execute`/
const rootWindow = window;
request.execute(gcEvent => {
rootWindow.open(gcEvent.htmlLink);
})
})
})
}
仅使用 moment(event.start).utc().format("YYYY-MM-DDTHH:mm:ss.SSS[Z]")
