在Azure门户中,可以从该功能的“集成”页面轻松配置Azure功能的输出绑定.
这些设置最终进入function.json.
这些设置最终进入function.json.
我的问题是,如何从Visual Studio中设置这些值?
代码如下所示:
public static class SomeEventProcessor { [FunctionName("SomeEventProcessor")] public static async Task<HttpResponseMessage> Run( [HttpTrigger(AuthorizationLevel.Function,"get","post",Route = null)]HttpRequestMessage req,TraceWriter log,IAsyncCollector<EventInfo> outputQueue) { log.Info("C# HTTP trigger function processed a request."); EventInfo eventInfo = new EventInfo(); //Just a container eventInfo.SomeID = req.Headers.Contains("SomeID") ? req.Headers.GetValues("SomeID").First() : null; //Write to a queue and promptly return await outputQueue.AddAsync(eventInfo); return req.CreateResponse(HttpStatusCode.OK); } }
我想从VS中指定要使用哪个队列和哪个存储,以便我可以控制我的代码和配置.我已经检查了类似的问题,建议的问题等,但没有一个被证明是方便的.
我在用
Visual Studio 2017预览版,15.3.0版预览版3
VS Extension:VS的Azure函数工具,版本0.2
解决方法
绑定被指定为触发器,使用它们应绑定的参数的属性.绑定配置(例如,队列名称,连接等)作为属性参数/属性提供.
public static class SomeEventProcessor { [FunctionName("SomeEventProcessor")] public static async Task<HttpResponseMessage> Run( [HttpTrigger(AuthorizationLevel.Function,"post")]HttpRequestMessage req,[Queue("myQueueName",Connection = "myconnection")] IAsyncCollector<EventInfo> outputQueue) { log.Info("C# HTTP trigger function processed a request."); EventInfo eventInfo = new EventInfo(); //Just a container eventInfo.SomeID = req.Headers.Contains("SomeID") ? req.Headers.GetValues("SomeID").First() : null; //Write to a queue and promptly return await outputQueue.AddAsync(eventInfo); return req.CreateResponse(HttpStatusCode.OK); } }
如果您只是从HTTP函数返回200(确定),则可以通过将该属性应用于方法的返回值来进一步简化代码,再次使用您的代码作为示例,它将如下所示:
[FunctionName("SomeEventProcessor")] [return: Queue("myQueueName",Connection = "myconnection")] public static EventInfo Run( [HttpTrigger(AuthorizationLevel.Function,TraceWriter log) { log.Info("C# HTTP trigger function processed a request."); EventInfo eventInfo = new EventInfo(); //Just a container eventInfo.SomeID = req.Headers.Contains("SomeID") ? req.Headers.GetValues("SomeID").First() : null; return eventInfo; }
