卷曲"(6) Could not resolve host: http"

Question

我正在尝试运行此命令

curl -XPUT -H "Content-Type: application/json" https://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

但这导致了这个错误

curl: (6) Could not resolve host: http
curl: (3) unmatched close brace/bracket in URL position 5:
null}'

我从这里得到这个命令

我还不太熟悉卷曲和弹性，所以我不知道如何确定的错误

如果有区别的话，我使用的是Windows。

我也试过

$ curl -X PUT -H "Content-Type: application/json" https://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

第2版：

我试过

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

但是现在得到这个错误

{"error":{"root_cause":[{"type":"json_parse_exception","reason":"Unexpected character (''' (code 39)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@446f2dd5; line: 1, column: 2]"}],"type":"json_parse_exception","reason":"Unexpected character (''' (code 39)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@446f2dd5; line: 1, column: 2]"},"status":400}curl: (3) unmatched close brace/bracket in URL position 5: null}' ^

然后我尝试了

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d "{"index.blocks.read_only_allow_delete": null}"

我得到

{"error":{"root_cause":[{"type":"json_parse_exception","reason":"Unexpected character ('i' (code 105)): was expecting double-quote to start field namen at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@696b36d3; line: 1, column: 3]"}],"type":"json_parse_exception","reason":"Unexpected character ('i' (code 105)): was expecting double-quote to start field namen at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@696b36d3; line: 1, column: 3]"},"status":400}

Answer 1

首先，在另一个SO问题中，ES节点是一个活动节点，因此其URL包含https。

您的本地主机几乎肯定不会有https，所以将其更改为http:

curl -XPUT -H "Content-Type: application/json" 
http://localhost:9200/_all/_settings 
-d '{"index.blocks.read_only_allow_delete": null}'

除此之外，只要您的ES正在运行，一切看起来都很好。

成功后，您应该收到一条简单的消息：

{"acknowledged":true}

编辑：使用

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d "{"index.blocks.read_only_allow_delete": null}"
