如何从React Native（expo）访问用户的谷歌日历？

Question

我使用Expo，我想添加访问我的应用程序的用户有一个谷歌帐户。然后我需要得到有关用户登录到我的应用程序谷歌日历的信息。

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']

当有人试图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",
    },
}

我收到了关于用户的数据，但我没有关于它的日历的任何数据。我尝试使用以下函数获取有关日历（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 [

           ],
           "expires": Array [
             "Thu, 17 Jan 2019 11:30:32 GMT",
           ],

           ],
           "x-content-type-options": Array [
             "nosniff",
           ],
           "x-frame-options": Array [
             "SAMEORIGIN",
           ],
           "x-xss-protection": Array [
             "1; mode=block",
           ],
         },
       },

如何获得世博会用户谷歌日历列表？

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。GetUserScalendarListschulde如下所示：

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