Gmail API返回状态代码400，错误“邮件服务未启用” [英] Gmail API returning status code 400, error "Mail service not enabled"

问题描述

我最近开始从gmail API看到以下错误：

  {
code：400， 
错误：[{
domain：global，
message：邮件服务未启用，
reason：failedPrecondition
 $ b]，
message：邮件服务未启用
} 
  

我测试过的每个gmail API调用都会导致错误，但下面的代码显示了一个正常的示例：

  public static列表与LT;字符串> getThreadIdsFromRFC822MessageIds（Collection< String> messageIds，User u）抛出IOException，NoOauthCredentialsException {
 List< String> queryTerms = new ArrayList<>（）; 
 for（String messageId：messageIds）{
 queryTerms.add（rfc822msgid：+ messageId）; 
} 
 String queryString = Joiner.on（OR）.join（queryTerms）; 
字符串fieldSelectionString =messages / threadId; 
 
 ListMessagesResponse messages = executeMessageQuery（u，queryString，fieldSelectionString）; 
列表< String> threadIds = new ArrayList<>（）; （message.getMessages（）！= null）{
 for（Message m：messages.getMessages（））{
 threadIds.add（m.getThreadId（））; 
} 
} 
 return threadIds; 
} 
 
 private static ListMessagesResponse executeMessageQuery（User u，String queryString，String fieldSelectionString）throws IOException，NoOauthCredentialsException {
 assert fieldSelectionString.length（）> 0; 
 Gmail g = GmailAPIHelper.getGmailService（u）; 
 Gmail.Users.Messages.List query = g.users（）。messages（）。list（me）.setQ（queryString）.setFields（fieldSelectionString）; 
 ListMessagesResponse messages = executeAndLog（query，u）; 
返回消息; 
} 
  

其中，executeAndLog在Gmail.Users.Messages.List对象上调用.execute。

这个错误只影响到我的很小一部分用户，并且错误信息表明这是一个权限问题。我希望询问我的用户重新授权可以解决问题，但是我担心在出现权限问题时，我会收到此错误消息，而不是更常见的401。有没有人看过这个错误？

I recently started seeing the following error from the gmail API:

{
  "code" : 400,
  "errors" : [ {
    "domain" : "global",
    "message" : "Mail service not enabled",
    "reason" : "failedPrecondition"
  } ],
  "message" : "Mail service not enabled"
}

Every gmail api call I've tested causes the error, but the following code shows a normal example:

public static List<String> getThreadIdsFromRFC822MessageIds(Collection<String> messageIds, User u) throws IOException, NoOauthCredentialsException {
    List<String> queryTerms = new ArrayList<>();
    for (String messageId: messageIds) {
        queryTerms.add("rfc822msgid:" + messageId);
    }
    String queryString = Joiner.on(" OR ").join(queryTerms);
    String fieldSelectionString = "messages/threadId";

    ListMessagesResponse messages = executeMessageQuery(u, queryString, fieldSelectionString);
    List<String> threadIds = new ArrayList<>();
    if (messages.getMessages() != null) {
        for (Message m : messages.getMessages()) {
            threadIds.add(m.getThreadId());
        }
    }
    return threadIds;
}

private static ListMessagesResponse executeMessageQuery(User u, String queryString, String fieldSelectionString) throws IOException, NoOauthCredentialsException {
    assert fieldSelectionString.length() > 0;
    Gmail g = GmailAPIHelper.getGmailService(u);
    Gmail.Users.Messages.List query = g.users().messages().list("me").setQ(queryString).setFields(fieldSelectionString);
    ListMessagesResponse messages = executeAndLog(query, u);
    return messages;
}

Where executeAndLog calls .execute on the Gmail.Users.Messages.List object.

This error is only affecting a very small number of my users, and the error message suggests that it is a problem with permissions. I expect that asking my users to reauthorize will fix the issue, but I am concerned that I'm getting this error message instead of the more usual 401 when there's a permission problem. Has anyone seen this error?
