Gmail API：权限不足 [英] Gmail API: Insufficient Permission

问题描述

状况

我正在测试 Gmail API 。

我已经测试了一些请求，他们正常工作。
例如获取消息，获取用户历史记录，获取草稿列表等。

基本上所有只读请求正常工作

我已经提出了与其他请求相关的一些与许可相关的问题，例如我必须写或删除一个草稿。

这是我得到的错误：

 （403）权限不足
  

代码

这是初始化应用程序：

  public function gmail_init_service（）
 {
 $ client = new Google_Client（）; 
 
 $ client-> setApplicationName（Gmail API测试）; 
 $ client-> setDeveloperKey（MY_KEY）; 
 $ client-> setClientSecret（'MY_CLIENT_SECRET'）; 
 $ client-> SetClientId（'MY_CLIENT_ID'）; 
 $ client-> setScopes（array（'https://mail.google.com/'））; 
 $ client-> setAccessToken（{access_token：MY_ACCESS_TOKEN，token_type：承载，expires_in：3600，refresh_token：MY_REFRESH_TOKEN，created：1433502343} ）; 
 
 $ service = new Google_Service_Gmail（$ client）; 
 
 return $ service; 
} 
  

这是删除一个草案的请求：

  public function gmail_delete_draft（）
 {
 $ service = $ this-> gmail_init_service（）; 
 
 // ---------------获取草稿清单-------------- 
 
 $ list = $ service-> users_drafts-> listUsersDrafts（'me'）; 
 $ draftList = $ list-> getDrafts（）; 
 
 // ---------------获取草稿编号--------------- 
 
 $ inbox_draft = []; 
 
 foreach（$ draftList为$ mlist）
 {
 $ draftId = $ mlist-> id; 
 $ optParamsGet2 ['format'] ='full'; 
 $ single_message = $ service-> users_drafts-> get（'me'，$ draftId，$ optParamsGet2）; 
 
 $ inbox_draft [] ['draftId'] = $ draftId; 
 $ inbox_draft [] ['draft'] = $ single_message; 
} 
 
 // ---------------删除草稿--------------- 
 
 $ draft_delete = $ service-> users_drafts-> delete（'me'，'DRAFT_ID'）; 
} 
  

编辑：

我已经尝试撤销权限并设置新的凭据。
初始化服务时声明的范围是：

  https://mail.google.com/ 
 / b 
 
 
 
如文档中所述，授予帐户的完整访问权限。
 
 
 
但我仍然收到相同的错误。 
以下请求的确切错误：
 
 
 
删除草稿 - 创建草稿 - 创建标签 - 删除邮件
 
 
 
 问题： 
 
 
 
为什么我得到这个错误？
 
它与相同的值存储在缓存中？
 
或与API的许可相关？
解决方案
您需要' a href =https://www.googleapis.com/auth/gmail.compose =nofollow noreferrer> https://www.googleapis.com/auth/gmail.compose '来创建一个草案。那么如果你
  $ client-> setScopes（array（
'https://mail.google .com /'，
'https://www.googleapis.com/auth/gmail.compose'
））; 
  
或如果您想获得更正式的
  define（'SCOPES'，implode（''，array（
 Google_Service_Gmail :: MAIL_GOOGLE_COM，
 Google_Service_Gmail :: GMAIL_COMPOSE）
））; 
 
 $ client-> setScopes（SCOPES）
  
或任何有效的php可能（我没有做过php一段时间）。
 
 
 
 注意，如果你已经有一个令牌，你可能需要做一些戒律可以撤销它，以便您可以使用添加的权限重新发行。这可能意味着删除文件，也许命名为 gmail.storage ，或者，如果您有权访问帐户登录名，并进入 https://security.google.com/settings/security/permissions ，可以手动撤销访问权限。

THE SITUATION:

I am testing the Gmail API for my app.

I have tested some requests and they are working fine.
For example get messages, get user history, get draft list etc..

Basically all the read only requests are working fine.

I have instead some issues related with permission with other requests, for example when i have to write or delete a draft.

This is the error i get: 
(403) Insufficient Permission
THE CODE:

This is the function to initialize the app:
public function gmail_init_service()
{
    $client = new Google_Client();

    $client->setApplicationName("Gmail API test");
    $client->setDeveloperKey("MY_KEY");
    $client->setClientSecret('MY_CLIENT_SECRET');
    $client->SetClientId('MY_CLIENT_ID');
    $client->setScopes(array('https://mail.google.com/'));
    $client->setAccessToken('{"access_token":"MY_ACCESS_TOKEN","token_type":"Bearer","expires_in":3600,"refresh_token":"MY_REFRESH_TOKEN","created":1433502343}');

    $service = new Google_Service_Gmail($client);

    return $service;
}
This is the request to delete one draft:
public function gmail_delete_draft()
{
    $service = $this->gmail_init_service();

    // --------------- Get draft list --------------

    $list = $service->users_drafts->listUsersDrafts('me');
    $draftList = $list->getDrafts();

    // --------------- Get draft IDs ---------------

    $inbox_draft = [];

    foreach($draftList as $mlist)
    {
        $draftId = $mlist->id;
        $optParamsGet2['format'] = 'full';
        $single_message = $service->users_drafts->get('me', $draftId , $optParamsGet2);

        $inbox_draft[]['draftId'] = $draftId;
        $inbox_draft[]['draft'] = $single_message;
    }

    // --------------- Delete draft ---------------

    $draft_delete = $service->users_drafts->delete('me', 'DRAFT_ID' );
}
EDIT:

I have tried to revoke the permission and setup new credentials.
The scope declared when initializing the service is:
https://mail.google.com/
that as stated in the documentation grant full access to the account.

But i am still getting the same error.
The same exact error for the following requests:

Delete draft - Create draft - Create label - Delete message

THE QUESTION:

Why am i getting that error?

It has to do with same values store in a cache?

Or is related with permission of the API?
解决方案
You need 'https://www.googleapis.com/auth/gmail.compose' to create a draft. So what happens if you 
$client->setScopes(array(
    'https://mail.google.com/',
    'https://www.googleapis.com/auth/gmail.compose'
));
or if you want to get more formal
define('SCOPES', implode(' ', array(
  Google_Service_Gmail::MAIL_GOOGLE_COM,
  Google_Service_Gmail::GMAIL_COMPOSE)
));

$client->setScopes(SCOPES)
or whatever the valid php might be (I haven't done php for a while).

Note that if you have a token already you might have to do some calisthenics to revoke it so you can reissue with the added permissions.  That might mean deleting a file, perhaps named gmail.storage or, if you have access to the account login and make your way to https://security.google.com/settings/security/permissions the access permissions can be manually revoked.

This link might be relevant:
https://developers.google.com/gmail/api/auth/scopes

And a meander through the source code might be enlightening.

You might be able to glean some insight from my battle with this same sort of thing under Python
