它总是说您请求的页面无效。我如何使用 google 联系人 api 使用 javascript 获取联系人我有有效的范围和客户 ID

google.load('gdata', '2.x');
    debugger
    google.setOnLoadCallback(function () {
        if (window.location.hash == "") {
            if (!checkLogin()) {
                logMeIn();
            } else {
                var feedUrl = "https://www.google.com/m8/feeds/contacts/default/full";
                query = new google.gdata.contacts.ContactQuery(feedUrl);
                query.setMaxResults(5000);
                myService = new google.gdata.contacts.ContactsService('exampleCo-exampleApp-1.0');
                myService.getContactFeed(query, function (result) {
                    document.cookie = "g314-scope-0=";
                    window.opener.parseGmailContacts(result.feed.entry);
                    close();
                }, function (e) {
                    alert(e.cause ? e.cause.statusText : e.message);
                });
            }
        }
    });
    function logMeIn() {
        scope = "https://www.google.com/m8/feeds";
        var token = google.accounts.user.login(scope);
    }
    function logMeOut() {
        google.accounts.user.logout();
    }
    function checkLogin() {
        scope = "https://www.google.com/m8/feeds/";
        var token = google.accounts.user.checkLogin(scope);
        return token;
    }

我觉得有问题

  var token = google.accounts.user.checkLogin(scope);
            return token;

token retuns ""（这里是空值），如何获取token的值来获取联系人，请帮忙

【问题讨论】：

我认为 var myService = new google.gdata.contacts.ContactsService('exampleCo-exampleApp-1.0'); 有问题这个

【解决方案1】：

我遇到了同样的问题，我通过首先检索访问令牌来解决它，然后直接调用 API。这是因为 javascript api (gapi) 不支持检索 google 联系人。

由于很麻烦，我在这里写了一篇关于它的博文：https://labs.magnet.me/nerds/2015/05/11/importing-google-contacts-with-javascript.html

基本上我就是这样解决的：

<!DOCTYPE html>
<html>
  <head>
    <meta charset='utf-8' />
    <script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>
  </head>
  <body>
    <script type="text/javascript">
          var clientId = 'your Client ID';
          var apiKey = 'Your API Code';
          var scopes = 'https://www.googleapis.com/auth/contacts.readonly';

          $(document).on("click",".googleContactsButton", function(){
            gapi.client.setApiKey(apiKey);
            window.setTimeout(authorize);
          });

          function authorize() {
            gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: false}, handleAuthorization);
          }

          function handleAuthorization(authorizationResult) {
            if (authorizationResult && !authorizationResult.error) {
              $.get("https://www.google.com/m8/feeds/contacts/default/thin?alt=json&access_token=" + authorizationResult.access_token + "&max-results=500&v=3.0",
                function(response){
                  //process the response here
                  console.log(response);
                });
            }
          }
        </script>
        <script src="https://apis.google.com/js/client.js"></script>
        <button class="googleContactsButton">Get my contacts</button>
  </body>
</html>

【讨论】：

这适用于本地 HTML 文件，但是当我在服务器的项目中使用它时，我得到CORS header ‘Access-Control-Allow-Origin’ does not match ‘*’。有什么想法吗？
clientId 和 apiKey 在源代码 javascript 中不安全？

【解决方案2】：

尝试使用组件我的朋友。生活会变得更轻松、更美好。

要使用 Google plus 获取联系人列表，请使用：-

<script src="https://apis.google.com/js/client.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script>
  function auth() {
    var config = {
      'client_id': 'OAUTH_CLIENT_ID',
      'scope': 'https://www.google.com/m8/feeds'
    };
    gapi.auth.authorize(config, function() {
      fetch(gapi.auth.getToken());
    });
  }

  function fetch(token) {
    $.ajax({
    url: "https://www.google.com/m8/feeds/contacts/default/full?access_token=" + token.access_token + "&alt=json",
    dataType: "jsonp",
    success:function(data) {
              console.log(JSON.stringify(data));
    }
});
}

在 HTML 正文中：-

<button onclick="auth();">GET CONTACTS FEED</button>

输出将包含一个包含电话号码的联系人字段。

确保使用正确的重定向 uri 从谷歌开发者控制台获取客户端 ID。

每次单击按钮时弹出窗口闪烁都有轻微问题。将下面的 sn-p 添加到 Wouters 解决方案将停止弹出窗口闪烁。

function authorize(){
    if($scope.authorizationResult){
      handleAuthorization($scope.authorizationResult);
    }else{
gapi.auth.authorize({client_id: clientId, scope: scopes, immediate:false}, handleAuthorization);
       } 
    }
