在本教程中,你将了解如何将图像上传到 Azure Blob 存储并使用 Azure Functions、计算机视觉和 Cosmos DB 对其进行处理。 你还将了解如何在此过程中实现 Azure Function 触发器和绑定。 这些服务将一起分析包含文本的上传图像,从中提取文本,然后将文本存储在数据库行中,供以后分析或用于其他用途。
要创建 Blob 触发器,请创建 Azure 存储帐户并提供触发器监视的位置。 如何创建 Blob 触发器 正如我们目前见过的其他触发器,你可以在 Azure 门户中创建 blob 触发器。 在 Azure 函数中,从预定义的触发器类型列表中选择“Blob 触发器”。 然后,输入在创建或更新 blob 时要执行的逻辑。 有必要了解的一项设置是“...

利用Azure Function监控Blob文件变化,Azure Functions的一大优点就是提供了不同类型的触发器(http Trigger,Blob Trigger,Timer Trigger,Queue Trigger…),这里我们正好利用上Blob Trigger用来监控Blob文件的变化。 首先是创建一个Azure Functions的Project 然后指定Function是用Blob Trigger的。 创建ListeningBlob函数, usingSys...
Function bindings In order to interface with image data, you need to configure the function to process binary data. The following code sets thedatatypeparameter tobinaryin thefunction.jsonfile. JavaScript {"disabled":false,"bindings": [ {"type":"eventGridTrigger","name":"myEv...
在Azure Function中,部署了定时触发器函数(Timer Trigger),却无法按时触发。 问题解答 登录Function的Kudu站点,查看 logfiles中 application/function/host目录下的日志文件,发现错误消息: Singleton lock renewal failed for blob 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/host' with error code 409: LeaseIdMismatchWi...

Triggers mainly at present are Blob, Queue, Table, Eventhub, Http, Timer etc. In order to make an azure function trigger on a SQL change, there can be two possible ways. 1. Defining Custom Binding in Azure functions 2. If not the binding on Azure Functions side...
You want to connect your blob triggered function to a storage account, but you don’t want to put your connection string or secrets into the configuration. Prior to Azure Blobs extension 5.0.0, this was your only option, but not anymore. With these later
