我在从 ADF 和 Postman 向持久函数（Azure Functions 的扩展）发出 post 请求时遇到问题

Question

我可以从 ADF 和 postman 调用 azure 函数，但是当我从 ADF 或 postman 调用持久函数时，出现错误：

Operation on target Azure Function1 failed: Call to provided Azure function '' failed with status-'NotFound' and message - 'Invoking Azure function failed with HttpStatusCode - NotFound.'.

我已经尝试了所有方法，但不知道为什么会这样。我通过 functionApp 中的门户创建了持久函数，如下所示：

DurableFunctionsHttpStart1:

#r "Microsoft.Azure.WebJobs.Extensions.DurableTask"
#r "Newtonsoft.Json"

using System.Net;

public static async Task<HttpResponseMessage> Run(
    HttpRequestMessage req,
    DurableOrchestrationClient starter,
    ILogger log)
{
    // Function input comes from the request content.
    dynamic eventData = await req.Content.ReadAsAsync<object>();

    // Pass the function name as part of the route 
    string instanceId = await starter.StartNewAsync("DurableFunctionsOrchestrator1", null);

    log.LogInformation($"Started orchestration with ID = '{instanceId}'.");

    return starter.CreateCheckStatusResponse(req, instanceId);
}

DurableFunctionsOrchestrator1:

/*
 * This function is not intended to be invoked directly. Instead it will be
 * triggered by an HTTP starter function.
 * 
 * Before running this sample, please:
 * - create a Durable activity function (default name is "Hello")
 * - create a Durable HTTP starter function
 */

#r "Microsoft.Azure.WebJobs.Extensions.DurableTask"

public static async Task<List<string>> Run(DurableOrchestrationContext context)
{
    var outputs = new List<string>();

    // Replace "Hello" with the name of your Durable Activity Function.
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "Tokyo"));
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "Seattle"));
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "London"));

    // returns ["Hello Tokyo!", "Hello Seattle!", "Hello London!"]
    return outputs;
}

你好1:

/*
 * This function is not intended to be invoked directly. Instead it will be
 * triggered by an orchestrator function.
 * 
 * Before running this sample, please:
 * - create a Durable orchestration function
 * - create a Durable HTTP starter function
 */

#r "Microsoft.Azure.WebJobs.Extensions.DurableTask"

using System;
using System.Threading;

public static string Run(string name)
{
    Thread.Sleep(260000);
    return $"Hello {name}!";
}

我从 ADF 端调用 DurableFunctionsHttpStart1 函数，这将调用 orchestrator 函数并调用 activity。请指导

更新： 在 ADF 上重现您的错误，这就是您现在面临的问题：

如果你在ADF中的函数是这样的，你会得到上面的错误。 （方法也需要post）

这是ADF中azure函数的配置应该是：

然后它在我的 ADF 上工作正常。

原答案：

这些代码在我这边运行良好：

DurableFunctionsHttpStart1

#r "Microsoft.Azure.WebJobs.Extensions.DurableTask"
#r "Newtonsoft.Json"

using System.Net;

public static async Task<HttpResponseMessage> Run(
    HttpRequestMessage req,
    DurableOrchestrationClient starter,
    string functionName,
    ILogger log)
{
    // Function input comes from the request content.
    dynamic eventData = await req.Content.ReadAsAsync<object>();

    // Pass the function name as part of the route 
    string instanceId = await starter.StartNewAsync("DurableFunctionsOrchestrator1", eventData);

    log.LogInformation($"Started orchestration with ID = '{instanceId}'.");

    return starter.CreateCheckStatusResponse(req, instanceId);
}

DurableFunctionsOrchestrator1

/*
 * This function is not intended to be invoked directly. Instead it will be
 * triggered by an HTTP starter function.
 * 
 * Before running this sample, please:
 * - create a Durable activity function (default name is "Hello")
 * - create a Durable HTTP starter function
 */

#r "Microsoft.Azure.WebJobs.Extensions.DurableTask"

public static async Task<List<string>> Run(DurableOrchestrationContext context)
{
    var outputs = new List<string>();

    // Replace "Hello" with the name of your Durable Activity Function.
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "Tokyo"));
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "Seattle"));
    outputs.Add(await context.CallActivityAsync<string>("Hello1", "London"));

    // returns ["Hello Tokyo!", "Hello Seattle!", "Hello London!"]
    return outputs;
}

using System;
using System.Threading;
public static string Run(string name)
{
    Thread.Sleep(260000);
    return $"Hello {name}!";
}

并且所有功能都触发良好，最后：
