無法發佈節流事件的WSO2 APIM GW錯誤消息

將WSO2 APIM v2.0作爲2個節點運行並將WSO2 DAS作爲單獨的節點運行。無法發佈節流事件的WSO2 APIM GW錯誤消息

每次節流發生在WSO2 APIM，我在網關錯誤日誌中看到以下錯誤消息

我也沒能看到從WSO2 APIM統計API Throttled Out Requests報告。

請指教。

你對這個資源有'Authentication：None'嗎？ – Bee

是的，我沒有使用身份驗證。 –

這是一個已知問題，當您對資源有Authentication:none時。據報道爲here，並將在未來的版本中修復。

這個描述相當的技術性，我不太明白。只是爲了確認，由於這個錯誤，我將無法查看「API限制出的請求」報告？任何解決方法可用？ –

解決方法是爲每個資源的「Authentication Type」設置「none」以外的內容。 – Bee
