Question

我们使用REST API运行与Gmail同步的服务。自上周三以来，我们的一些（未更改的）Gmail测试已经开始偶尔失败。原因出现在Gmail REST API端。

一个失败的测试涉及创建标签，创建消息，使用标签标记消息，然后重命名标签。如果测试失败，更改标签名称的POST请求将返回 404 错误。在第一个 404 之前或之后，该标签或标签列表上的GET将成功返回相关标签。重试POST会导致 404 至少持续30秒，即使重试之间间隔为5秒。在尝试POST之前添加15秒的延迟无济于事。

这是一个已知问题吗？如果是这样，有没有任何已知的解决方法？我们可以提供什么来帮助诊断和解决这个问题？我们正在使用Google-HTTP-Java-Client / 1.22.0客户端库。

查看几次运行，Server响应标头值在成功和失败之间有所不同（尽管可能是设计）。

Answer 1

这是一个非常特殊的错误。标签的修补似乎被打破了。我也得到Error 404 (Not Found)!!1。到底怎么回事？！

同时您可以获取标签数据，然后更新可以更改的字段，只需根据您的喜好更改名称：

请求1

GET https://www.googleapis.com/gmail/v1/users/me/labels/Label_203?access_token={access_token}

回复1

{
 "id": "Label_203",
 "name": "test1234",
 "messageListVisibility": "show",
 "labelListVisibility": "labelShow",
 "type": "user",
 "messagesTotal": 0,
 "messagesUnread": 0,
 "threadsTotal": 0,
 "threadsUnread": 0
}

请求2

PUT https://www.googleapis.com/gmail/v1/users/me/labels/Label_203?access_token={access_token}

{
 "id": "Label_203",
 "labelListVisibility": "labelShow",
 "messageListVisibility": "show",
 "name": "test12345"
}

回复2

{
 "id": "Label_203",
 "name": "test12345",
 "messageListVisibility": "show",
 "labelListVisibility": "labelShow"
}

更新

由于某些奇怪的原因，API Explorer无法运行。但是，如果您在请求中从POST更改为PATCH，则会起作用：

请求

PATCH https://www.googleapis.com/gmail/v1/users/me/labels/Label_203?access_token={access_token} { "name": "wow123" }

<强>响应

{ "id": "Label_203", "name": "wow123", "messageListVisibility": "show", "labelListVisibility": "labelShow", "type": "user", "messagesTotal": 0, "messagesUnread": 0, "threadsTotal": 0, "threadsUnread": 0 }

零星错误使用Gmail REST API重命名标签 - 已知问题？解决方法？
