错误400

Question

我正在尝试通过JavaScript V3 API访问博客。如果我尝试访问我的(公共)测试博客，一切都会像预期的那样工作。

如果我使用相同的代码，但试图访问我的(私有)测试博客，我会得到一个错误。

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]);
            }
        });

api_key和blog_id中的第二个元素是我的私人博客。

和

{

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

        }

  },
  "status": 400,
  "statusText": null
}

我已经在开发人员控制台中设置了凭据。我通过localhost:5000/访问它，我已经在开发人员控制台中将localhost设置为一个有效域。

我唯一能想到的可能是

"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."
    }

这可能是告诉我，我的要求原产地是无效的，但我不能肯定。

如果我将相同的(私有)博客公开并重新执行，那么这段代码适用于两个博客ID。

我哪里出问题了？

Answer 1

Blogger要求您的应用程序在访问私有博客上的信息时必须具有OAuth 2.0令牌(请参阅这里的文件)。只有使用API密钥才不会使请求工作。

如果这些帖子是在私人博客上发布的，那么授权是必需的。如果这些帖子是在一个公开的博客上发布的，那么这个方法可以不经授权就被调用。

而且，当使用OAuth令牌时，作用域是不同的-

下面是Blogger的OAuth 2.0作用域信息： https://www.googleapis.com/auth/blogger 要使用Google2.0请求访问，您的应用程序需要范围信息以及OAuth在应用程序注册期间提供的信息(例如客户机ID和/或客户端机密)。

您可以通过https://developers.google.com/apis-explorer/#search/blogger.posts.list/m/blogger/v3/blogger.posts.list测试此API。
