java - Gmail api 范围和格式不匹配

Question

我正在尝试为 android 编写微型 gmail 客户端作为培训。我从 https://developers.google.com/gmail/api/quickstart/android 中获取了 gmail api 指南示例稍微修改它以通过线程获取带有标题和正文的消息。我将范围设置为 GmailScopes.Gmail_modify 并将主要请求函数编辑为:

private List<String> getDataFromApi() throws IOException {
            // Get the labels in the user's account.
            String user = "me";
            List<String> labels = new ArrayList<String>();
            ListLabelsResponse listResponse =
                    mService.users().labels().list(user).execute();
            ListThreadsResponse listThreads = null;
            try {
             listThreads = mService.users().threads().list(user).execute();
            } catch (IOException ioex){
                Log.e(LOG_TAG, "First: " + ioex.toString());
            }

            for (Thread thread : listThreads.getThreads()) {
                try {
                    thread = mService.users().threads().get(user, thread.getId()).setFormat("full").execute();
                } catch (IOException ioex){
                    Log.e(LOG_TAG, "Second: " + ioex.toString());
                }
                for(Message message : thread.getMessages()){
                    labels.add(message.getId());
                }

            }
            return labels;
        }

但我总是得到

Second: GoogleJsonResponseException: 403 Forbidden            {
                                                                             "code" : 403,
                                                                             "errors" : [ {
                                                                               "domain" : "global",
                                                                               "message" : "Metadata scope doesn't allow format FULL",
                                                                               "reason" : "forbidden"
                                                                             } ],
                                                                             "message" : "Metadata scope doesn't allow format FULL"
                                                                           }

我尝试了不同的范围配置，但服务范围似乎始终设置为 GmailScopes.GMAIL_METADATA

这正是我最近在使用 Google APIs Explorer 时遇到的问题。这是我为解决它所做的工作:

1. 转到 https://security.google.com/settings/security/permissions
2. 选择您正在玩的应用，我的是 Google APIs Explorer
3. 点击删除 > 确定
4. 下次，只需准确请求您需要的权限即可。

希望对你有帮助:)
