使用Javascript在OAuth2.0上使用Google Spreadsheets API

问题描述

我正在尝试使用Javascript访问私人Google电子表格。我已成功获得OAuth2.0授权，可以看到我所有Google云端硬盘文档的列表。我似乎无法做的是进入一个特定的电子表格。代码如下，函数retrieveAllFiles中的相关电子表格代码。其中很多都是从Google教程中挑选出来的。

I'm trying to access a private Google Spreadsheet using Javascript. I have sucessfully authorized with OAuth2.0 and can see a listing of all my Google Drive docs. What I can't seem to do is get into a specific spreadsheet. Code is as follows with the relevant spreadsheet code in the function "retrieveAllFiles". A lot of this is culled from Google tutorials.

var clientId = 'working';
var apiKey = 'working';
var scopes = 'https://www.googleapis.com/auth/drive.file https://www.googleapis.com/auth/drive https://spreadsheets.google.com/feeds';

function handleClientLoad() {
    console.log('inside handleClientLoad function');
    gapi.client.setApiKey(apiKey);
    window.setTimeout(checkAuth,1);
}

function checkAuth() {
    console.log('inside checkAuth function');
    gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: true}, handleAuthResult);
    console.log('finished checkAuth function');
}

function handleAuthResult(authResult) {
    console.log('inside handleAuthResult function');
    var authButton = document.getElementById('authButton');
    authButton.style.display = 'none';
    if (authResult && !authResult.error) {
        //Access token has been succesfully retrieved, requests can be sent to the API.
        apiCalls();
    } else {
        //No access token could be retrieved, show the button to start the authorization flow.
        authButton.style.display = 'block';
        authButton.onclick = function() {
            gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: false}, handleAuthResult);
        };
    }
}

function apiCalls() {
    console.log('inside apiCalls function');
    gapi.client.load('drive', 'v2', function() {
         retrieveAllFiles(callback);
    });
}

function retrieveAllFiles(callback) {
     $.get('http://spreadsheets.google.com/feeds/spreadsheets/private/full', function(data) {
        console.log('get request processed');
        console.log(data);
    });
    console.log('inside retrieveAllFiles function');
    var retrievePageOfFiles = function(request, result) {
        request.execute(function(resp) {
        result = result.concat(resp.items);
        var nextPageToken = resp.nextPageToken;
        if (nextPageToken) {
            request = gapi.client.drive.files.list({
                'pageToken': nextPageToken
            });
            retrievePageOfFiles(request, result);
        } else {
            callback(result);
        }
        });
    }
    var initialRequest = gapi.client.drive.files.list();
    retrievePageOfFiles(initialRequest, []);
}

function callback(result) {
    console.log('all should be loaded at this point');
    console.log(result);
    $('#drive-list').append('<ul class="items"></ul>');
    $.map(result, function(v,i){
        $('.items').append('<li>' + v.title + ':' + v.id + '</li>');
    });
}

所以要明确，最终结果是我所有Google的列表驱动文档，但没有用于获取数据处理的console.log。我在控制台中没有收到任何错误消息，所以我不知道发生了什么。

So to be clear, the end result currently is a listing of all my Google Drive docs, but no console.log for "get data processed". I'm not getting any error messages in the console, so I can't tell what is going on.

谢谢。

Final solution compiled from a bunch of different sources, hopefully this will help someone.

var scopes = 'https://spreadsheets.google.com/feeds';
var clientId = 'working';
var apiKey = 'working';

function handleClientLoad() {
    console.log('inside handleClientLoad function');
    gapi.client.setApiKey(apiKey);
    window.setTimeout(checkAuth,1);
}

function checkAuth() {
    console.log('inside checkAuth function');
    gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: true}, handleAuthResult);
    console.log('finished checkAuth function');
}

function handleAuthResult(authResult) {
    console.log('inside handleAuthResult function');
    console.log(gapi.auth.getToken());
    var authButton = document.getElementById('authButton');
    authButton.style.display = 'none';
    if (authResult && !authResult.error) {
        //Access token has been successfully retrieved, requests can be sent to the API.
        loadClient();
    } else {
        //No access token could be retrieved, show the button to start the authorization flow.
        authButton.style.display = 'block';
        authButton.onclick = function() {
            gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: false}, handleAuthResult);
        };
    }
}

function loadClient() {
    console.log('inside loadClient function');
    var token = gapi.auth.getToken().access_token;
    var urlLocation = ''; //Get this from the URL of your Spreadsheet in the normal interface for Google Drive.

    //This gives a spitout of ALL spreadsheets that the user has access to.
    var url = 'https://spreadsheets.google.com/feeds/spreadsheets/private/full?access_token=' + token;

    //This gives a list of all worksheets inside the Spreadsheet, does not give actual data
    var url = 'https://spreadsheets.google.com/feeds/worksheets/' + urlLocation + '/private/full?access_token=' + token;

    //This gives the data in a list view - change the word list to cells to work from a cell view and see https://developers.google.com/google-apps/spreadsheets/#working_with_cell-based_feeds for details
    var url = 'https://spreadsheets.google.com/feeds/list/' + urlLocation + '/od6/private/full?access_token=' + token;

    console.log(url);
    $.get(url, function(data) {
        console.log(data);
    });
}
