javascript - 使用 node.js 连接到 ravendb

Question

我目前正在尝试使用 node.js 和 ravendb 建立一个小项目。但是当我尝试连接到 ravendb 测试服务器或本地服务器时，我收到以下错误：

(node:20336) UnhandledPromiseRejectionWarning: AllTopologyNodesDownException: Tried to send BatchCommand request via POST http://live-test.ravendb.net/databases/Northwind/bulk_docs to all configured nodes in the topology, all of them seem to be down or not responding.

索引.js

const { DocumentStore } = require('ravendb');

const store = new DocumentStore("http://live-test.ravendb.net", "Northwind");

store.initialize();   

const session = store.openSession();

async function asyncFunction() {
    let test = {
        name: 'abc',
        value: '123',
    };

    await session.store(test, 'test/');
    console.log(test.id);
    await session.saveChanges();
}

asyncFunction()

store.dispose();

包.json

{
  "dependencies": {
    "ravendb": "^4.1.5"
  }
}

Answer 1

您可以尝试将最后两行更改为：

asyncFunction()
    .then(() => store.dispose());

您不是在等待异步函数调用并在调用DocumentStore后立即处理asyncFunction()。

DocumentStore.dispose()应在应用程序关闭时调用。它清理缓存并关闭打开的连接。

Answer 2

试试这样：

import { DocumentStore } from "ravendb";

const store = new DocumentStore(["http://live-test.ravendb.net"],"Northwind");                       

const conventions = store.conventions;  

store.initialize();
