【问题描述】：
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();
}
}
为了迁移，我为新的应用服务重写了它，
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);
但是当我执行它时，我得到了一个内部服务器错误，说 Error: Cannot find module 'azure'
这是完整的错误日志：

<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.

有人知道我应该怎么做才能修复脚本吗？提前致谢！
【问题讨论】：
-
在使用
require('azure')之前，您是否在新的应用服务应用程序中安装了 Azure SDK for node？span> -
嗨@GaryLiu-MSFT 感谢您的回复，但我该怎么做呢？有没有办法只使用 azure 在线门户安装它？
-
嗨@Vincent，有什么更新吗？
