卷曲“（6）无法解析主机：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}'

但这会导致这个错误

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

我对 curl 和 elasticseach 还不是很熟悉，所以我不确定如何查明错误

如果有什么不同，我使用的是 Windows。

我也试过了

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

我试过了

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

但是现在出现这个错误

{"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}"

我得到了

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

首先，在另一个 SO 问题中，ES 节点是一个实时节点，因此它的 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，一切看起来都不错，前提是您的 ES 正在运行。

成功后，您应该会收到一条简单的消息：

{"acknowledged":true}

编辑：继续

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