ServiceBus 绑定中断 Node.js Azure 函数

ServiceBus binding breaks Node.js Azure Function

我有一个由 http

触发的简单 azure 函数
module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');

    context.res = {
        // status: 200, /* Defaults to 200 */
        body: "Success"
    };
}

function.json

{
  "bindings": [
    {
      "authLevel": "function",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "type": "http",
      "direction": "out",
      "name": "res"
    }
  ]
}

此时我可以触发函数并查看响应。

然后我尝试将服务总线绑定添加到 function.json

{
  "bindings": [
    ...
    {
      "type": "serviceBus",
      "direction": "out",
      "name": "outputSbTopic",
      "topicName": "topicName",
      "connection": "ServiceBusConnection"
    }
  ]
}

当我添加函数 returns 404 的绑定时,日志中没有任何内容。我什至没有开始使用绑定。

有什么问题吗?我在这个问题上苦苦挣扎了 2 个多小时,没有更多的想法。

host.json(以防万一)

{
  "version": "2.0",
  "extensions": {
    "serviceBus": {
      "prefetchCount": 100,
      "messageHandlerOptions": {
        "autoComplete": true,
        "maxConcurrentCalls": 32,
        "maxAutoRenewDuration": "00:05:00"
      }
    }
  }
}

运行时版本 ~2

Node.js 版本 Node.js 12 LTS

应用程序 运行 处于包文件的只读模式。

AppType 函数AppLinux

更新 我使用 VS Code Azure Function Extension 创建了该函数,并使用 DevOps 进行了部署。后来我在 azure portal 中手动创建了函数。对比两个函数的App Service Editor文件,发现我的第一个函数在host.json中没有extensionBundle。就是这个原因。

用你的host.json也遇到同样的问题:

问题似乎出在您的函数应用程序中的 host.json。

我这边的文件是:

index.js

module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    var message = "This is a test to output to service bus.";
    context.bindings.testbowman = message;
    context.done();
    context.res = {
        status: 200,
        body: "This is a test to output to service bus topic."
    };
};

function.json

{
  "bindings": [
    {
      "authLevel": "anonymous",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "type": "http",
      "direction": "out",
      "name": "res"
    },
    {
        "name": "testbowman",
        "type": "serviceBus",
        "topicName": "testbowman",
        "connection": "str",
        "direction": "out"
    }
  ]
}

host.json

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[1.*, 2.0.0)"
  }
}

local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "node",
    "str":"Endpoint=sb://testbowman.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=xxxxxx="
  }
}

成功了:
