我正在将我的应用从旧的azure移动服务迁移到新的azure应用服务。
在旧的azure移动服务中，我使用此表脚本插入到我的图像表中。
var azure = require('azure');
var qs = require('querystring');
var appSettings = require('mobileservice-config').appSettings;
function insert(item, user, request) {
// Get storage account settings from app settings.
var accountName = appSettings.STORAGE_ACCOUNT_NAME;
var accountKey = appSettings.STORAGE_ACCOUNT_ACCESS_KEY;
var host = accountName + '.blob.core.windows.net';
if ((typeof context.item.containerName !== "undefined") && (
context.item.containerName !== null)) {
// Set the BLOB store container name on the item, which must be lowercase.
context.item.containerName = context.item.containerName.toLowerCase();
// If it does not already exist, create the container
// with public read access for blobs.
var blobService = azure.createBlobService(accountName, accountKey, host);
blobService.createContainerIfNotExists(context.item.containerName, {
publicAccessLevel: 'blob'
}, function (error) {
if (!error) {
// Provide write access to the container for the next 5 mins.
var sharedAccessPolicy = {
AccessPolicy: {
Permissions: azure.Constants.BlobConstants.SharedAccessPermissions.WRITE,
Expiry: new Date(new Date().getTime() + 5 * 60 * 1000)
}
};
// Generate the upload URL with SAS for the new image.
var sasQueryUrl =
blobService.generateSharedAccessSignature(context.item.containerName,
context.item.resourceName, sharedAccessPolicy);
// Set the query string.
context.item.sasQueryString = qs.stringify(sasQueryUrl.queryString);
// Set the full path on the new new item,
// which is used for data binding on the client.
item.imageUri = sasQueryUrl.baseUrl + sasQueryUrl.path;
} else {
console.error(error);
}
context.execute();
});
} else {
context.execute();
}
}
要迁移，我会为新的应用服务重写它，
var table = module.exports = require('azure-mobile-apps').table();
var azure = require('azure');
var qs = require('querystring');
var appSettings = require('mobileservice-config').appSettings;
function insertPhoto(context) {
// Get storage account settings from app settings.
var accountName = appSettings.STORAGE_ACCOUNT_NAME;
var accountKey = appSettings.STORAGE_ACCOUNT_ACCESS_KEY;
var host = accountName + '.blob.core.windows.net';
if ((typeof context.item.containerName !== "undefined") && (
context.item.containerName !== null)) {
// Set the BLOB store container name on the item, which must be lowercase.
context.item.containerName = context.item.containerName.toLowerCase();
// If it does not already exist, create the container
// with public read access for blobs.
var blobService = azure.createBlobService(accountName, accountKey, host);
blobService.createContainerIfNotExists(context.item.containerName, {
publicAccessLevel: 'blob'
}, function (error) {
if (!error) {
// Provide write access to the container for the next 5 mins.
var sharedAccessPolicy = {
AccessPolicy: {
Permissions: azure.Constants.BlobConstants.SharedAccessPermissions.WRITE,
Expiry: new Date(new Date().getTime() + 5 * 60 * 1000)
}
};
// Generate the upload URL with SAS for the new image.
var sasQueryUrl =
blobService.generateSharedAccessSignature(context.item.containerName,
context.item.resourceName, sharedAccessPolicy);
// Set the query string.
context.item.sasQueryString = qs.stringify(sasQueryUrl.queryString);
// Set the full path on the new new item,
// which is used for data binding on the client.
item.imageUri = sasQueryUrl.baseUrl + sasQueryUrl.path;
} else {
console.error(error);
}
context.execute();
});
} else {
context.execute();
}
};
table.insert(insertPhoto);
然而，当我执行它时，我收到内部服务器错误，说错误：找不到模块'azure'
以下是完整的错误日志：

<h3>HTTP Error 500.1002 - Internal Server Error</h3>
<h4>The page cannot be displayed because an internal server error has occurred.</h4>
</div>
<div class="content-container">
<fieldset>
<h4>Most likely causes:</h4>
<ul> <li>IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.</li> <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.</li> <li>IIS was not able to process configuration for the Web site or application.</li> <li>The authenticated user does not have permission to use this DLL.</li> <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li> </ul>
</fieldset>
</div>
<div class="content-container">
<fieldset>
<h4>Things you can try:</h4>
<ul> <li>Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.</li> <li>Check the event logs to see if any additional information was logged.</li> <li>Verify the permissions for the DLL.</li> <li>Install the .NET Extensibility feature if the request is mapped to a managed handler.</li> <li>Create a tracing rule to track failed requests for this HTTP status code.

任何人都知道我应该怎么做来修复脚本？先谢谢！
答案 0 :(得分：1)
随着移动应用程序的体系结构从移动服务更改，现在移动应用程序将迁移到Azure应用程序服务。
实际上，Node.js中的Mobile Apps后端是一个expressjs项目，mobile app sdk for node是express的中间件。
因此，您可以将移动应用程序下载到本地（请参阅How to: Download the Node.js backend quickstart code project using Git），我们可以利用应用程序根目录中的package.json文件来维护您需要的nodejs模块，然后通过git部署到Azure ，Azure App Service将通过部署任务安装依赖项。您可以参考Using Node.js Modules with Azure applications了解更多信息。
同时，您可以利用Kudu Console站点或Visual Studio在线扩展在线快速安装nodejs模块。您可以参考How to run django manage.py command on Azure App Service的答案，了解这些在线工具的一般概念。
如有任何疑问，请随时告诉我。
