javascript - ElasticSearch 创建索引类型错误

Question

我正在使用elasticsearch npm 模块。创建索引会导致类型错误，其消息为:

Unable to build a path with those params. Supply at least index

我使用的代码如下所示:

    var client = new elasticsearch.Client({
        host: 'localhost:9200',
        log: 'trace'
    });

    client.indices.create('myindex', function (err, resp) {
        if (err)
            console.log('failed to create ElasticSearch index, ' + err.message);
        else
            console.log('successfully created ElasticSearch index');
    });

根据index create docs ，我应该能够传递带有索引名称的字符串。我很困惑为什么它通常会失败，以及为什么错误消息引用路径。

create() 的第一个参数必须是一个字典。尝试:

client.indices.create({index: 'myindex'}, function (err, resp) {
    if (err)
        console.log('failed to create ElasticSearch index, ' + err.message);
    else
        console.log('successfully created ElasticSearch index');
});
