Question

天蓝网络作业中队列触发功能是否有时间限制。我的功能大约需要20-30分钟，因为它需要查看数据库中的大量记录。最后的功能状态是从未完成。我使用{＆＃34; stopping_wait_time＆＃34;：1800}放入了settings.job文件 - 没有任何效果。但是在五分钟左右的时间里，它的状态将被设置为Never Finished。我搜索过，是的，发现一些人问类似的问题 - 没有明确的答案。我在日志中发现了一些例外，似乎是从Azure存储生成异常。我搜索并发现日志记录存在一些问题，所以我在功能中注释了日志代码 - 仍然没有去。此外，我发现一个问题提到了一些连接字符串 - 所以现在我有这些; AzureWebJobsStorage，AzureWebJobsDashboard，AzureJobsRuntime，AzureJobsData - 都指向相同的存储帐户 - 仍然没有。

我尝试调试，看看超时发生的地方，看起来它甚至在我的功能实际被击中之前就已经发生了，

输出如下所示;

System.TimeoutException：客户端无法在指定的超时内完成操作。

我正在使用S1网络应用程序和标准GRS存储帐户。

所以问题是;
1.队列触发功能的时间是否有时间限制？
2.如果有时间限制，有没有办法超越这些？
3.我必须使用队列触发函数，因为我需要将一些参数传递给函数 - 这些参数是从另一个计划的Web作业传递的。我可以创建一个按需webjob并在命令行上传递参数 - 但是有没有办法从预定的webjob调用按需webjob？

感谢您的帮助！

队列触发的作业功能的执行时间没有限制。但是，有一些事项可以确保您正确设置，以便JobHost继续运行。使用Azure WebJobs SDK时，您需要将JobHost Console exe作为持续运行的WebJob 进行部署，并启用始终开启。这些都在＆＃34;创建一个持续运行的WebJob＆＃34;的this documentation page上详细描述。部分。

参见＆＃34; Notes＆＃34;该页面的部分，了解在免费套餐（20分钟超时）中运行时超时限制的相关详细信息，可以通过转移到基本或标准层来删除。
