Azure函数获取订阅中的资源组列表-Nodejs

Question

我创建了一个函数，可以让我获得订阅中的资源组列表

// Function to get the resource group
const getHttp = async (subscriptionId) => {
    const response = await fetch(
        `https://management.azure.com/subscriptions/${subscriptionId}/resourcegroups?api-version=2019-10-01`
    );

    if (response.status === 200) {
        const data = await response.json();
        return data;
    } else {
        throw new Error(
            'Unable to get list of resource group from Azure' +
                ' ' +
                response.status
        );
    }
};

module.exports = async function (context, req) {
    context.log('ListRG proccessed a request');
    const subscriptionId = 'xxx';

    const json = await getHttp(subscriptionId);

    console.log(json);
    context.log(json);
    context.res = { body: json };
};

但我明白了：

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

这个错误：

2020-08-07T11:25:27.915 [Error] Executed 'Functions.ListRg' (Failed, Id=4a10c117-5ded-4bb4-882e-94ec4eb6e28b, Duration=36ms)Result: FailureException: Error: Unable to get list of resource group from AzureStack: Error: Unable to get list of resource group from Azureat getHttp (D:\home\site\wwwroot\ListRg\index.js:12:9)at processTicksAndRejections (internal/process/task_queues.js:97:5)at async module.exports (D:\home\site\wwwroot\ListRg\index.js:20:15)

对于权限，我使用托管身份并在我的订阅中赋予函数 Reader 角色

我错过了什么？

根据您的要求，虽然我们已启用 MSI，但我们无法直接调用其余 api。如果您想使用 MSI 请求资源组列表，请参考下面我提供的解决方案：

1. 安装模块：

npm install ms-rest-azure
npm install azure-arm-resource

2.请参考下面我的代码：

const msRestAzure = require("ms-rest-azure");
const { ResourceManagementClient } = require("azure-arm-resource");

module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');

    credentials = await msRestAzure.loginWithAppServiceMSI({ resource: 'https://management.azure.com' });

    const subscriptionId = '<your subscription id>';

    const resourceClient = new ResourceManagementClient(credentials, subscriptionId);

    let finalResult = await resourceClient.resourceGroups.list();

    finalResult.forEach(element => { 
        console.log(element); 
    });

    context.res = { body: 'success' };

}

顺便说一句，我的解决方案使用 sdk 来执行请求。如果你想直接在你的函数代码中请求apihttps://management.azure.com/subscriptions/{subscriptionId}/resourcegroups?api-version=2019-10-01，你需要先获取访问令牌，然后在你的“获取”的标题中设置令牌。但在我看来，我建议你使用 sdk。
