我已经输入了这个命令来索引 Elasticsearch 中的文档
创建索引
curl -X PUT "localhost:9200/test_idx_1x"
创建映射
curl -X PUT "localhost:9200/test_idx_1x/test_mapping_1x/_mapping" -d '{
"test_mapping_1x": {
"properties": {
"my_attachments": {
"type": "attachment"
}
}
}
}'
索引此文档
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"
}'
这三个命令都非常好。但是当我输入这个命令时:
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"
}
}'
我收到此错误消息:
{
"error": "NullPointerException[null]",
"status": 500
}
我把它改成;
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"
}
}'
输出是相同的错误。
我就这样改
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 ..."
}
}'
错误是
{
"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: [B@159b3; 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"
}'
我收到此错误消息:
{
"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: [B@1ae9565; line: 1, column: 132]]; ",
"status": 400
}
如果我输入
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"
}'
我收到错误。我能理解
{
"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: [B@1ffb7d4; line: 1, column: 137]]; ",
"status": 400
}
如何使用附加文件到 ES 以便 ES 可以索引它?
感谢您的回答。当我键入这些命令时,我已经安装了那个附件插件。文本文件的内容是用Base64编码的,所以我不再编码了。如果我不使用文件的路径,而是直接使用 Base 64 中的内容,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,我已经成功发布文件并稍后搜索其内容。
但是如果我用路径的文件替换它,我会得到负面的结果。所以我想知道如何在命令行中,在 ES 索引命令中对文件进行 Base64 编码(当然,我不想在输入第二个命令在 ES 中对文件进行索引之前输入 base64 命令来编码文件)。作为您的回答,我是否必须安装“Perl 库”之类的东西才能执行您的命令?
