Google Blogger API 错误 400

Question

我正在尝试通过 JavaScript V3 API 访问 Blogger。如果我尝试访问我的（公共）测试博客，一切都会按预期进行。

如果我使用相同的代码但尝试访问我的（私人）测试博客，我会收到错误消息。

以下是我的代码

        var client_id = ['WWWW', 'XXXX'];
        var api_key = ['YYYY','ZZZZ'];
        var discoveryDocs = ['https://www.googleapis.com/discovery/v1/apis/blogger/v3/rest'];
        var scope = 'https://www.googleapis.com/auth/blogger.readonly';
        var blog_id = ['BLOG0', 'BLOG1'];

        var appendResults = function(results) {
          $('#results').append(JSON.stringify(results, undefined, 2) + '<hr/>');
        };

        getBlogs = function(client, key, blog) {
            gapi.client.init({
                'apiKey': key,
                'clientId': client,
                'discoveryDocs': discoveryDocs,
                'scope': scope
            }).then(function() {
                return gapi.client.blogger.posts.list({
                    'blogId': blog
                });
            }).then(function(d) {
                return d;
            }).then(function(response) {
                appendResults(response);
            }, function(reason) {
                appendResults(reason);
            });
        };

        gapi.load('client', function() {
            for(i=0; i<api_key.length; i++) {
                getBlogs(client_id[i], api_key[i], blog_id[i]);
            }
        });

其中 api_key 和 blog_id 中的第二个元素是我的私人博客。

以下是我的回复

和

{

    "error": {
      "errors": [
        {
          "domain": "global",
          "reason": "invalid",

  },

}

我已经在开发者控制台中设置了凭据。我正在通过 localhost:5000/ 访问它，我已将 localhost 设置为开发人员控制台中的有效域。

我能想到的唯一线索是

"result": {
    "error": {
      "errors": [
        {
          "domain": "global",
          "reason": "invalid",
          "message": "We're sorry, but the requested resource could not be found."
        }
      ],
      "code": 400,
      "message": "We're sorry, but the requested resource could not be found."
    }

这可能告诉我我的请求来源无效，但我不能确定。

如果我将同一个（私人）博客公开并重新执行，则此代码适用于两个博客 ID。

我哪里出错了？

Answer 1

Blogger API 要求您的应用程序在访问私人博客上的信息时具有 OAuth 2.0 令牌（请参阅 documentation here）。仅使用 API 密钥不会使请求生效。

如果帖子位于私人博客上，则需要Authorization。如果帖子在公开的博客上，则可以在未经授权的情况下调用此方法。

此外，使用 OAuth 令牌时范围不同 -

以下是 Blogger API 的 OAuth 2.0 范围信息：

https://www.googleapis.com/auth/blogger 

要使用 OAuth 2.0 请求访问权限，您的应用程序需要范围信息以及 Google 在应用程序注册期间提供的信息（例如 作为客户端 ID 和/或客户端密码）。
