隊列觸發的Azure Webjob的時間限制

Question

azure Web作業中的隊列觸發功能是否有時間限制？ 我的函數大約需要20-30分鍾，因為它需要遍歷數據庫中的許多記錄。 最后的功能狀態為“永不結束”。 我將{。“ stopping_wait_time”：1800}放入settings.job文件-沒有任何效果。 但是在五分鍾左右的時間內，其狀態將設置為“永不結束”。 我搜索了，是的，發現有人問類似的問題-沒有明確的答案。 我在日志中發現了一些異常，這些異常似乎是從Azure存儲生成的。 我搜索發現日志記錄存在一些問題，因此我注釋掉了函數中的日志記錄代碼-仍然行不通。 我也發現了一個提到一些連接字符串的問題-現在我有了這些。 AzureWebJobsStorage，AzureWebJobsDashboard，AzureJobsRuntime，AzureJobsData-都指向同一個存儲帳戶-仍然無法使用。

我嘗試進行調試，看看超時發生在哪里，甚至在我的函數真正被執行之前，它似乎正在發生，

輸出如下所示；

System.TimeoutException：客戶端無法在指定的超時時間內完成操作。

我為此使用了一個S1 Web應用程序和一個標准GRS存儲帳戶。

問題是；
1.隊列觸發功能花費的時間是否有時間限制？
2.如果有時間限制，有什么方法可以克服這些限制？
3.我必須使用隊列觸發的函數，因為我需要將一些參數傳遞給該函數-這些參數是從另一個計划的Web作業傳遞的。 我可以按需制作Webjob並在命令行上傳遞參數-但是有沒有辦法從計划的webjob調用按需Webjob？

謝謝你的幫助！

隊列觸發的作業功能的執行時間沒有限制。 但是，您需要確保設置正確，以便JobHost繼續運行。 使用Azure WebJobs SDK時，需要將JobHost Console exe部署為連續運行的WebJob ，並啟用Always On 。 在本文檔頁面的“創建連續運行的WebJob”部分下對此都有詳細說明。
