如何从 React Native (expo) 访问用户的谷歌日历？

Question

我使用 Expo，我想向拥有 Google 帐户的用户添加对我的应用程序的访问权限。然后我需要获取登录到我的应用程序的用户的 Google 日历信息。

我使用：Expo.Google.logInAsync(options) (https://docs.expo.io/versions/latest/sdk/google) 实现登录功能。我的范围如下所示：

scopes: ['https://www.googleapis.com/auth/userinfo.email',
         'https://www.googleapis.com/auth/userinfo.profile',
         'https://www.googleapis.com/auth/calendar.readonly']

当有人尝试登录我的应用程序时，它会询问查看日历列表的权限。作为回应，我得到：

Object {
    "accessToken": "a",
    "idToken": "b",
    "refreshToken": "c",
    "serverAuthCode": "d",
    "type": "success",
    "user": Object {
        "email": "e",
        "familyName": "f",
        "givenName": "g",
        "id": "h",
        "name": "i",
        "photoUrl": "j",
    },
}

我收到了有关该用户的数据，但没有任何有关其日历的数据。 我尝试使用此函数获取有关日历 (https://developers.google.com/calendar/v3/reference/calendarList) 的数据：

getUsersCalendarList = async (accessToken) => {
    let calendarsList = await fetch('https://www.googleapis.com/calenda/v3/users/me/calendarList', {
    headers: { Authorization: `Bearer ${accessToken}`},
    });
    return calendarsList;
}

我得到了回应：

 Response {
       "_bodyBlob": Blob {
         "_data": Object {
           "blobId": "67b8b161-690f-4ff6-9cee-1dce12840ebd",
           "offset": 0,
           "size": 994,
         },
       },
       "_bodyInit": Blob {
         "_data": Object {
           "blobId": "67b8b161-690f-4ff6-9cee-1dce12840ebd",
           "offset": 0,
           "size": 994,
         },
       },
       "headers": Headers {
         "map": Object {
           "alt-svc": Array [
             "quic=\":443\"; ma=2592000; v=\"44,43,39,35\"",
           ],
           "cache-control": Array [
             "public, max-age=0",
           ],
           "content-type": Array [
             "application/json; charset=UTF-8",
           ],
           "date": Array [
             "Thu, 17 Jan 2019 11:30:32 GMT",
           ],
           "expires": Array [
             "Thu, 17 Jan 2019 11:30:32 GMT",
           ],
           "server": Array [
             "GSE",
           ],
           "vary": Array [
             "X-Origin",
           ],
           "x-content-type-options": Array [
             "nosniff",
           ],
           "x-frame-options": Array [
             "SAMEORIGIN",
           ],
           "x-xss-protection": Array [
             "1; mode=block",
           ],
         },
       },
       "ok": false,
       "status": 403,
       "statusText": undefined,
       "type": "default",
       "url": "https://www.googleapis.com/calendar/v3/users/me/calendarList",
     }

如何在 Expo 中获取用户的谷歌日历列表？

Answer 1

我在这里找到了解决方案：React-Native JSON fetch from URL。需要对返回的对象使用json() 函数。 getUsersCalendarList schulde 看起来像这样：

getUsersCalendarList = async (accessToken) => {
    let calendarsList = await fetch('https://www.googleapis.com/calenda/v3/users/me/calendarList', {
    headers: { Authorization: `Bearer ${accessToken}`},
    });
    return calendarsList.json();
}

您还可以将访问令牌作为参数添加到请求中。

https://www.googleapis.com/calenda/v3/users/me/calendarList?access_token={token}

我不是 React 开发人员，因此不确定如何修复您的标题。看起来不错。
