我正在使用带有 Azure 的 Terraform 创建一个函数应用程序来演示一个 web 应用程序（带有 nodejs 的 Pi 计算器）。

在 Azure 门户中创建 Function App 时，它可以工作；使用如下设置。

函数应用 Azure 设置

之后，我将使用“开发环境”门户内 -> Webhook + API 添加一个新功能。它有效！

工作PiCalc

但是当我用 Terraform 创建它时它不起作用。我正在使用这段代码：

主文件

    version = "=1.34.0"
}

resource "azurerm_resource_group" "rg" {
    name     = "rg"
    location = "westeurope"

  resource_group_name      = "${azurerm_resource_group.rg.name}"
  location                 = "${azurerm_resource_group.rg.location}"
  account_tier             = "Standard"
  account_replication_type = "LRS"

  location            = "${azurerm_resource_group.rg.location}"
  resource_group_name = "${azurerm_resource_group.rg.name}"
  kind                = "FunctionApp"

  sku {

  container_access_type = "private"
}

  app_settings = {
    FUNCTIONS_WORKER_RUNTIME = "node"

index.js

// node.js application to calculate pi as a Azure Function App
// P.Burghouwt HHS 2019
// <URL>?n=<number of decimals>  (default=20 if no n specified)

const Decimal = require("decimal.js");
Decimal.config({precision: 10});
function pi(n) {    
    var p16 = new Decimal(1);
    var pi = new Decimal(0);
    var precision=n;
    Decimal.precision=precision;
    var one = new Decimal(1);
    var two = new Decimal(2);
    var four = new Decimal(4);
    var k8 = new Decimal(0);
    for (var k = new Decimal(0); k.lte(precision); k = k.plus(one)) {
      var f = four.div(k8.plus(1))
          .minus(two.div(k8.plus(4)))
          .minus(one.div(k8.plus(5)))
          .minus(one.div(k8.plus(6)));
      pi = pi.plus(p16.times(f));
      p16 = p16.div(16);
      k8 = k8.plus(8);
    }
    return pi;
}

module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    if (req.query.n || (req.body && req.body.n)) { 
        var n=(req.query.n || req.body.n)
    }
    else {
        var n=20
    };
    var StartTime = new Date()
    var calculatePi = pi(n)
    var EndTime = new Date() - StartTime 
    context.res = {
             status: 200,   
             body: "{\"PI\":\n {\n  \"decimals\": " + (n) + ",\n  \"ms\": " + JSON.stringify(EndTime) + ",\n  \"value\": " + (calculatePi.toString()) + "\n }\n} "
    };
};

包.json

{
  "name": "picalc",
  "version": "1.0.0",
  "description": "Pi Calculation for node.js",
  "main": "index.js",
  "scripts": {

  },
  "author": "Pieter Burghouwt",
  "license": "MIT",
  "dependencies": {
    "decimal.js": "^10.2.0"
  }
}

这是我收到的错误消息：

错误信息

我尝试了多种方法来更改异步代码，但仍然无法正常工作。

任何人都知道问题是什么以及我如何解决这个问题？提前谢谢了！
