Question

有人可以看看这段代码并告诉我为什么我收到以下错误消息。我已经看过每一个方向，无法理解它为什么或在哪里被打破。

下面的代码显示了docDbClient的硬值，但我还使用了＆＃34; process.env.Document ...＆＃34;系统变量无效。这主要取自在线发现的Node Botbuilder样本。它应该连接到CosmosDb数据库。这应该只是加电。使用Bot框架模拟器，在服务器运行的命令提示符处生成错误消息。通过发布的网页尝试，它只是没有错误信息。

提前谢谢！

var restify = require('restify');
var builder = require('botbuilder');
var botbuilder_azure = require("botbuilder-azure");
var builder_cognitiveservices = require('botbuilder-cognitiveservices');

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function() {
    console.log('%s listening to %s', server.name, server.url);
});

// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
    appId: process.env.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword,
    openIdMetadata: process.env.BotOpenIdMetadata
});

// Listen for messages from users 
server.post('/api/messages', connector.listen());

var docDbClient = new botbuilder_azure.DocumentDbClient({
    host: 'https://xxxxx.table.cosmosdb.azure.com:443',
    masterKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
    database: 'TablesDB',
    collection: 'botdata'
});

var tableStorage = new botbuilder_azure.AzureBotStorage({ gzipData: false }, docDbClient);

// Create your bot with a function to receive messages from the user
var bot = new builder.UniversalBot(connector, function(session) {
    session.send('You said: %s', session.message.text);
    session.endDialog();
}).set('storage', tableStorage); // Register in Azure Storage

错误：

您似乎在混合使用Cosmos DB Table 端点和 DocumentDB 客户端实例，该实例解释了400 Bad Request。

对于DocumentDB API（注意host有.documents.而非.table.）：

var docDbClient = new botbuilder_azure.DocumentDbClient({
    host: 'https://xxxxx.documents.cosmosdb.azure.com:443',
    masterKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
    database: 'botdocs',
    collection: 'botdata'
});

var tableStorage = new botbuilder_azure.AzureBotStorage({ gzipData: false }, docDbClient);

将Azure表存储用于bot状态（这是常规表存储，如存储帐户，而不是Cosmos DB Table API）：

var azureTableClient = new azure.AzureTableClient(tableName, storageName, storageKey);
var tableStorage = new azure.AzureBotStorage({gzipData: false}, azureTableClient);

理论上，if you pass a Cosmos DB Table endpoint到azure.AzureTableClient()您可以将Cosmos用作表存储，表API在Azure存储和Cosmos之间是兼容的。我没有看到比标准DocumentDB类型有任何直接好处。

无法使用Node从Azure Bot连接到CosmosDb
