CouchDB：在文档中插入一个新数组

Question

我有一个文档，其中包含：

{
"_id": "00001.74365CF0449457AA5FB52822DBE1F22A",
"_rev": "1-1b976f3adb75c220aff28b4c69f41e18",
"game": "UT411",
"guid": "74365CF0449457AA5FB52822DBE1F22A",
"sid": "00001",
"playerinfo": [
   {
       "timestamp": "1315503699.777494167",
       "name": "Elisa",
       "ip": "87.66.181.166",
       "gear": "FMAOSTA",
       "weapmodes": "01000110220000020000",
       "isp": "ADSL-GO-PLUS",
       "geoloc": "Hotton:50.266701:5.450000",
       "sid": "00001"
   }
   ]
}

我想实现的是向playerinfo数组添加信息，以使我的文档看起来像这样。

{
"_id": "00001.74365CF0449457AA5FB52822DBE1F22A",
"_rev": "1-1b976f3adb75c220aff28b4c69f41e18",
"game": "UT411",
"guid": "74365CF0449457AA5FB52822DBE1F22A",
"sid": "00001",
"playerinfo": [
   {
       "timestamp": "1315503699.777494167",
       "name": "Elisa",
       "ip": "87.66.181.166",
       "gear": "FMAOSTA",
       "weapmodes": "01000110220000020000",
       "isp": "ADSL-GO-PLUS",
       "geoloc": "Hotton:50.266701:5.450000",
       "sid": "00001"
   },
   {
       "timestamp": "1315503739.234334167",
       "name": "Elisa-new",
       "ip": "87.66.181.120",
       "gear": "FMAGGGA",
       "weapmodes": "01000110220000020000",
       "isp": "ADSL-GO-PLUS",
       "geoloc": "Hotton:50.266701:5.450000",
       "sid": "00001"
   }
   ]
}

有没有使用HTML PUTs的方法来实现这个呢？

谢谢！

Answer 1

简单的答案是获取JSON文档/example_db/00001.74365CF0449457AA5FB52822DBE1F22A，修改内容，然后将其PUT回服务器，回到/example_db/00001.74365CF0449457AA5FB52822DBE1F22A。

CouchDB支持一种称为update function的快捷技术。原理相同，只是CouchDB会接收文档并进行您实现的任何更改，然后再次存储它-全部在服务器端完成。

我建议您从前者开始，使用更简单的技术。下一步，必要时可以重构以使用服务器端_update函数。
