elasticsearch python pycharm

Question

我正在尝试在 Python 中运行一个非常简单的 Elasticsearch 插入：

es = Elasticsearch({'host': 'localhost', 'port': 9200})
res = es.index(index='data-client_dev', doc_type='test', id=2, body={'author': 'Christophe'}, timeout=60)
print(res['created'])

但我总是在最后粘贴错误。 我在 Ubuntu 14 下并使用 PyCharm （如果这可能有帮助）。 ES 节点已在我的计算机上本地启动并运行。 我尝试更改超时（或使用 request_timeout），但它什么也没做。奇怪的是查询是从终端进行的，所以也许它是针对 Pycharm 的。 我是初学者，所以也许我错过了一些明显的东西。

非常感谢您的帮助！

Answer 1

您需要像这样创建 Elasticsearch 客户端，即将主机放入列表中：

es = Elasticsearch([{'host': 'localhost', 'port': 9200}])
                   ^                                   ^
                   |                                   |
                add this                           and this

我确实从 pyCharm IDE 安装了弹性搜索，它有效。
