node.js - 无法通过 Visual Studio Code 在本地运行 Azure Durable Function

Question

我按照教程Visual Studio Code quickstart进行操作并在本地创建了一个持久的函数。当我的持久函数在启动函数内执行等待 client.startNew 时，我收到一条错误消息

const instanceId = await client.startNew(req.params.functionName, undefined, req.body);

这是错误消息:

Executed 'Functions.HttpTrigger' (Failed, Id=84dc103d-bef9-4450-b4c6-9e612c6dc263) System.Private.CoreLib: Exception while executing function: Functions.HttpTrigger. System.Private.CoreLib: Result: Failure Exception: Error: write EPROTO 101057795:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:827: Stack: Error: write EPROTO 101057795:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:827: at _errnoException (util.js:992:11) at WriteWrap.afterWrite [as oncomplete] (net.js:864:14).

我的环境:

• Azure Functions 核心工具 (2.3.148)
• 函数运行时版本(2.0.12210.0)
• Node.js 8

这是我刚刚从教程中复制的代码。

const df = require("durable-functions");
module.exports = async function (context, req) {
        const client = df.getClient(context);
        const instanceId = await client.startNew(req.params.functionName, undefined, req.body);

        context.log(`Started orchestration with ID = '${instanceId}'.`);

        return client.createCheckStatusResponse(context.bindingData.req, instanceId);
    };

{
  "bindings": [
    {
      "authLevel": "anonymous",
      "name": "req",
      "type": "httpTrigger",
      "direction": "in",
      "route": "orchestrators/{functionName}",
      "methods": ["post"]
    },
    {
      "name": "$return",
      "type": "http",
      "direction": "out"
    },
    {
      "name": "starter",
      "type": "orchestrationClient",
      "direction": "in"
    }
  ]
}

如何解决这个问题？

更新

自 npm 包 durable-functions v1.1.3 以来，该问题已得到修复

您遇到了known issue .

This is due to current IWebHookProvider implementation, which causes the DurableOrchestrationClient class to use the wrong webhook URLs. The workaround is to set local environment variable WEBSITE_HOSTNAME to localhost:, ex. localhost:7071

如果在设置 env 之前已经打开 VS Code，请不要忘记重新启动它以使新的 env 变量生效。
