elasticsearch从入坑到放弃
今天在配置问答系统中使用到了elasticsearch，由于在Linux下开发界面不友好，就直接在Windows下配置环境进行开发，结果一不小心入了一个坑，折腾了三个多小时才弄出来，所以以后还是要用Linux开发。。。
从官网下载ES https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html
解压直接bin目录下运行 elasticsearch.bat，
通过elasticsearch的mapping文件创建index和type时，总是报错"Failed to parse content to map，Unexpected character ('m' (code 109)): was expecting double-quote to start field name
上官网查询格式，
https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html
官网生成的curl也是报错
curl -X PUT "localhost:9200/my_index" -H 'Content-Type: application/json' -d'
{
"mappings": {
"_doc": {
"properties": {
"title": { "type": "text" },
"name": { "type": "text" },
"age": { "type": "integer" },
"created": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
}
}
}
}
}
'
最后发现在原因是Windows系统的问题：将curl后命令用双引号引用，json内容用三个双引号引用
curl -X PUT "localhost:9200/my_index" -H "Content-Type: application/json" -d"
{
"""mappings""": {
"""_doc""": {
"""properties""": {
"""title""": { """type""": """text""" },
"""name""": { """type""": """text""" },
"""age""": { """type""": """integer""" },
"""created""": {
"""type""": """date""",
"""format""": """strict_date_optional_time||epoch_millis"""
}
}
}
}
}
"
