如何从持久函数协调器获取调用者函数名称？

Question

我有一个计时器触发器，它使用持久客户端调用协调器。有没有办法从协调器内部获取调用者函数的名称？

[FunctionName("Starter")]
public static async Task Starter(
    [TimerTrigger("0 0 1 * * *", RunOnStartup = true)] TimerInfo myTimer,
    [DurableClient] IDurableClient starter,
    ILogger log)
{
    await starter.StartNewAsync("Orchestrator", null);
}

[FunctionName("Orchestrator")]
public static async Task Orchestrator(
    [OrchestrationTrigger] IDurableOrchestrationContext context)
{
    // get caller function name here (Starter, in this example)
}

Answer 1

只需将一个参数传递给协调器：

[FunctionName("Starter")]
public static async Task Starter(
    [TimerTrigger("0 0 1 * * *", RunOnStartup = true)] TimerInfo myTimer,
    [DurableClient] IDurableClient starter,
    ILogger log)
{
    await starter.StartNewAsync("Orchestrator", "NAME_OF_THE_CALLER");
}

[FunctionName("Orchestrator")]
public static async Task Orchestrator(
    [OrchestrationTrigger] IDurableOrchestrationContext context)
{
    // get caller function name here (Starter, in this example)
    string caller = context.GetInput<string>();
}
