Azure函数-值不能为null.(参数"connectionString") [英] Azure Functions - Value cannot be null. (Parameter 'connectionString')

问题描述

我试图设置简单的Azure函数以读取XML流并将其同步回数据库.我的计划是每天使用时间触发器执行一次功能.

I was trying to setup simple Azure Function to read a XML stream and sync it back to the database. My plan was to use a Time Trigger to execute the function once per day.

但是，情况看起来并不好.即使不使用数据库，我也会遇到以下错误:

Howerver, things are not looking great. I'm getting the following error, even if I don't use a database:

[Error] Executed 'Functions.<func-name>' (Failed, Id=<func-id>, Duration=1ms)Value cannot be null. (Parameter 'connectionString')

我当前正在尝试执行以下功能:

I'm currently trying to execute the following function:

module.exports = async function(context, req) {
    context.res = {
        body: "Success!"
    };
};

相同的结果.我无法运行.

Same result. I can't run it.

我已将连接字符串添加到配置->连接字符串(根据消息，我认为我已经错过了).

I've added a Connection String to the Configuration -> Connection Strings (I thought that I've missed that, based on the message).

我的functions.json文件如下:

My functions.json file looks like:

{
  "bindings": [
    {
      "name": "myTimer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 0 * * * *"
    },
    {
      "type": "http",
      "direction": "out",
      "name": "res"
    }
  ]
}

我也尝试过运行C#函数-结果相同.

I've also tried running a C# function - same result.

那么，我错过了什么?

推荐答案

从Microsoft登录最好.

AzureWebJobsStorage应用设置丢失.

解决方案:

1. 创建存储帐户(或使用现有帐户)
2. 转到功能应用程序的配置
3. 将带有连接字符串的AzureWebJobsStorage添加到您的存储帐户(可以在存储帐户概述->访问密钥"中找到)
