我想使用curl命令获取JSON，所以使用下面的命令我得到输出：
curl -GET http://localhost:9200/oldindex/_mapping?pretty
{
"gl-events_1" : {
"mappings" : {
"message" : {
"dynamic" : "false",
"dynamic_templates" : [
{
"fields" : {
"path_match" : "fields.*",
"mapping" : {
"doc_values" : true,
"index" : true,
"type" : "keyword"
}
}
}
],
"properties" : {
"alert" : {
"type" : "boolean"
},
"event_definition_id" : {
"type" : "keyword"
},
"event_definition_type" : {
"type" : "keyword"
},
"fields" : {
"type" : "object",
"dynamic" : "true"
},
"id" : {
"type" : "keyword"
},
"key" : {
"type" : "keyword"
},
"key_tuple" : {
"type" : "keyword"
},
"message" : {
"type" : "text",
"norms" : false,
"fields" : {
"keyword" : {
"type" : "keyword"
}
},
"analyzer" : "standard"
},
"origin_context" : {
"type" : "keyword"
},
"priority" : {
"type" : "long"
},
"source" : {
"type" : "keyword"
},
"source_streams" : {
"type" : "keyword"
},
"streams" : {
"type" : "keyword"
},
"timerange_end" : {
"type" : "date",
"format" : "yyyy-MM-dd HH:mm:ss.SSS"
},
"timerange_start" : {
"type" : "date",
"format" : "yyyy-MM-dd HH:mm:ss.SSS"
},
"timestamp" : {
"type" : "date",
"format" : "yyyy-MM-dd HH:mm:ss.SSS"
},
"timestamp_processing" : {
"type" : "date",
"format" : "yyyy-MM-dd HH:mm:ss.SSS"
},
"triggered_jobs" : {
"type" : "keyword"
}
}
}
}
}
}
现在我想将此输出存储为 json 文件，因此我将其复制到文件中并给出扩展名.json
但是当我尝试使用 curl 时，出现以下错误
curl -X PUT http://localhost:9200/new_good -H 'Content-Type: application/json' -d sampl.json
{"error":{"root_cause":[{"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"}],"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"},"status":500}
但是当我直接使用相同的 json 格式运行下面的命令时它可以工作，
curl -X PUT \
http://localhost:9200/new_good \
-H 'Content-Type: application/json' \
-d '{"mappings" : {
"message" : {

我想要的是将curl GET命令输出存储为有效的json，我可以在curl PUT中使用它，
curl get > some.json
curl put -d some.json
我对此很陌生，我也尝试了 jq 的几种选择，但这对我来说也不起作用。
请在这里指导我。

要保存来自curl命令的JSON，您可以将输出重定向到您的案例中的文件。或者使用：
curl ... -o file.json
要使用 发送它curl，您可以使用以下命令运行命令
curl ... -d @file.json
来自：man curl-d --data <data>
如果您以字母@开头数据，则其余部分应该是从中读取数据的文件名，或者 - 如果您希望curl从stdin读取数据。
另外，将 json 通过管道传输到curl 命令的标准输入也可以工作，使用-d -.
