我在Elasticsearch索引附件文件到彈性搜索
創建索引
curl -X PUT "localhost:9200/test_idx_1x"
創建一個映射
curl -X PUT "localhost:9200/test_idx_1x/test_mapping_1x/_mapping" -d '{
"test_mapping_1x": {
"properties": {
"my_attachments": {
"type": "attachment"
}
}
}
}'
指數鍵入此命令索引文件本文件
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/4' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "test Elastic Search",
"name": "N1"
}'
所有這三個命令都是非常有用的。 但是,當我輸入以下命令:
curl -XPOST 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": {
"type": "attachment",
"_content_type": "text/plain",
"file": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt"
}
}'
我收到此錯誤消息:
{
"error": "NullPointerException[null]",
"status": 500
}
我把它變成;
curl -XPOST 'http://localhost:9200/test_idx_1x/test_mapping_1x/1bis' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": {
"type": "attachment",
"_content_type": "text/plain",
"_name": "/inf/bd/my_home_directory/test.txt"
}
}'
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": {
"file": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt"
}
}'
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": {
"file": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt",
"_content_type": "text/plain"
}
}'
輸出是相同的錯誤。
我改變它像
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"user": "kimchy",
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": {
"file": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt",
"_content_type": "text/plain",
"content": "... base64 encoded attachment ..."
}
}'
誤差
{
"error": "MapperParsingException[Failed to parse]; nested: JsonParseException[Failed to decode VALUE_STRING as base64 (MIME-NO-LINEFEEDS): Illegal character '.' (code 0x2e) in base64 content\n at [Source: [[email protected]; line: 1, column: 241]]; ",
"status": 400
}
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt"
}'
我收到此錯誤消息:
{
"error": "MapperParsingException[Failed to parse]; nested: JsonParseException[Unexpected character ('h' (code 104)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: [[email protected]; line: 1, column: 132]]; ",
"status": 400
}
如果I型
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/1' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": "http://localhost:5984/my_test_couch_db_7/ID2/test.txt"
}'
我收到錯誤消息。我可以理解它
{
"error": "MapperParsingException[Failed to parse]; nested: JsonParseException[Failed to decode VALUE_STRING as base64 (MIME-NO-LINEFEEDS): Illegal character ':' (code 0x3a) in base64 content\n at [Source: [[email protected]; line: 1, column: 137]]; ",
"status": 400
}
如何將附加文件用於ES以便ES可以對其進行索引?
感謝您的回答。我輸入這些命令時已經安裝的附件插件。文本文件的內容使用Base64編碼,因此我不再編碼它。如果我不使用該文件的路徑,但直接使用它的內容在基地64,例如。
curl -XPUT 'http://localhost:9200/test_idx_1x/test_mapping_1x/' -d '{
"post_date": "2009-11-15T14:12:12",
"message": "trying out Elastic Search",
"name": "N2",
"my_attachments": "file's content string encoded in base64"
}'
一切都很好,我已經成功發佈文件並在以後搜索其內容。
但是,如果我用路徑文件替換它,我獲得了負面結果。因此,我想知道如何在命令行中使用ES索引命令對Base64文件進行編碼(當然,在輸入第二個命令將其索引到ES中之前,我不想輸入base64命令對文件進行編碼)。作爲您的答案,我是否必須安裝「Perl庫」之類的東西來執行您的命令?
是你可以做的。使用您正在編程的任何語言的Base64編碼器。我使用命令行版本,因爲您的示例使用來自命令行的curl – DrTech
