放置令牌失败。状态代码：404 - Azure 函数 (Java) 无法被服务总线触发

Question

我尝试使用 VS Code 创建基于 Java 的简单 Azure Functions。我尝试从服务总线获取主题消息。

//local.settings.json（SAS 策略：RadioTopicPolicy = Manage/Read/Listen）

"topicconnstring":"Endpoint=sb://111standardsb.servicebus.windows.net/;SharedAccessKeyName=RadioTopicPolicy;SharedAccessKey 
       =11111nuAmrb16c3/cGaxe0dYGTz/tiBebTI+peG4zE=;"

此函数由服务总线主题触发并将数据存储到数据湖 binding example

package com.function;

import com.microsoft.azure.functions.annotation.*;
import com.microsoft.azure.functions.*;

/**
 * Azure Functions with Azure Storage Queue trigger.
*/ 
public class TopicTriggerCosmosOutput {
     /**
     * This function will be invoked when a new message is received at the specified path. The 
message contents are provided as input to this function.
    */ 

    @FunctionName("TopicTriggerDataLakeOutput")
    public void run(
        @ServiceBusTopicTrigger(
            name = "message",
            topicName = "radioTopic",
            subscriptionName = "RadioSubscription",
            connection = "topicconnstring"
        ) String message,
        final ExecutionContext context
    ) {
        context.getLogger().info(message);
    }

}

在 VS Code 中调试时出错：

Answer 1

此错误表示自动转发目标实体的目标不存在。目标实体（队列或主题）必须在源创建之前存在。创建目标实体后重试。

看看这个文档：

https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-resource-manager-exceptions#error-bad-request

我注意到你说

There is "Radio" Service Bus Topic and "RadioSubscription" Subscription in Azure Service Bus. There is "RadioTopicPolicy"

所以你的函数应该是这样的：

@FunctionName("TopicTriggerDataLakeOutput")
    public void run(
        @ServiceBusTopicTrigger(
            name = "message",
            topicName = "Radio",
            subscriptionName = "RadioSubscription",
            connection = "topicconnstring"
        ) String message,
        final ExecutionContext context
    ) {
        context.getLogger().info(message);
    }

并确保您的 SAS 令牌的主键正确。希望对您有所帮助。:)
