如何从React Native(expo)访问用户的谷歌日历？

Question

我使用世博会，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，我需要获取有关登录我的应用程序的用户的Google日历的信息。

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",
    },
}

我收到了有关用户的数据，但我没有任何关于其日历的数据。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;
}

作为回应，我得到了：

 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",
     }

如何在世博会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。需要在返回的对象上使用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添加为请求的参数。

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

我不是反应开发人员，所以不确定如何修复您的标头。看起来还行。
