删除数据 | base_url/delete/ | {
TableName:{<
增加 或 扩展 | "key+":Object,Object的类型由key指定,且类型为Number,String,JSONArray中的一种。如 82001,"apijson",["url0","url1"] 等。只用于PUT请求 | "praiseUserIdList+":[82001],添加一个点赞用户id,即这个用户点了赞
减少 或 去除 | "key-":Object,与"key+"相反 | "balance-":100.00,余额减少100.00,即花费了100元
逻辑运算 | &, \|, ! 逻辑运算符。
① & 可用于"key&{}":"条件"等
② \| 可用于"key\|{}":"条件", "key\|{}":[]等,一般可省略
③ ! 可单独使用,如"key!":Object,也可像&,\|一样配合其他功能符使用 | ① ["id&{}":">80000,<=90000"](http://apijson.cn:8080/head/{"User":{"id&{}":">80000,<=90000"}}),即id满足id>80000 & id<=90000
② ["id\|{}":">90000,<=80000"](http://apijson.cn:8080/head/{"User":{"id\|{}":">90000,<=80000"}}),同"id{}":">90000,<=80000",即id满足id>90000 \| id<=80000
③ ["id!{}":[82001,38710]](http://apijson.cn:8080/head/{"User":{"id!{}":[82001,38710]}}),即id满足 ! (id=82001 \| id=38710),可过滤黑名单的消息
- 数组关键词 | "key":Object,key为 "[]":{} 中{}内的关键词,Object的类型由key指定
① "count":Integer,查询数量,假设允许查询数组的最大数量为max(默认为100),则当count在1~max范围内时,查询count个;否则查询max个
② "page":Integer,查询页码,从0开始,一般和count一起用
③ "query":Integer,查询内容
0-对象,1-总数,2-以上全部
总数关键词为total,和query同级,通过引用赋值得到,如 "total@":"/[]/total"
这里query及total仅为GET类型的请求提供方便,一般可直接用HEAD类型的请求获取总数

"\<" - LEFT JOIN
">" - RIGHT JOIN
"&" - INNER JOIN
"\|" - FULL JOIN
"!" - OUTTER JOIN

["count":5](http://apijson.cn:8080/get/{"[]":{"count":5,"User":{}}})
② 查询第3页的User数组,每页5个:
["count":5,
"page":3](http://apijson.cn:8080/get/{"[]":{"count":5,"page":3,"User":{}}})
③ 查询User数组和对应的User总数:
["[]":{
"query":2,
"User":{}

对象关键词,可自定义 | "@key":Object,@key为 Table:{} 中{}内的关键词,Object的类型由@key指定
① "@combine":"key0,&key1,\|key2,!key3,...", 条件组合方式
② "@column":"key0,key1...", 返回字段
③ "@order":"key0,key1+,key2-...",排序方式
④ "@group":"key0,key1,key2...",分组方式。如果@column里声明了Table的id,则id也必须在@group中声明;其它情况下必须满足至少一个条件:
1.分组的key在@column里声明
2.Table主键在@group中声明
⑤ "@having":"function0(...)?valu0,function1(...)?valu1,function2(...)?value2...",SQL函数条件,一般和@group一起用,函数一般在@column里声明
⑥ "@otherKey": Object,自定义关键词,名称和以上系统关键词不一样,且原样返回上传的值 | ① 搜索name或tag任何一个字段包含字符a的User列表:
["name?":"a",
"tag?":"a",
"@combine":"name?,tag?"](http://apijson.cn:8080/get/{"User[]":{"count":10,"User":{"@column":"id,name,tag","name%253F":"a","tag%253F":"a","@combine":"name%253F,tag%253F"}}})
② 只查询id,sex,name这几列并且请求结果也按照这个顺序:
["@column":"id,sex,name"](http://apijson.cn:8080/get/{"User":{"@column":"id,sex,name","id":38710}})
③ 查询按 name降序、id默认顺序 排序的User数组:
["@order":"name-,id"](http://apijson.cn:8080/get/{"[]":{"count":10,"User":{"@column":"name,id","@order":"name-,id"}}})
④ 查询按userId分组的Moment数组:
["@group":"userId,id"](http://apijson.cn:8080/get/{"[]":{"count":10,"Moment":%7B"@column":"userId,id","@group":"userId,id"}}})
⑤ 查询 按userId分组、id最大值>=100 的Moment数组:
["@column":"userId,max(id)",
"@group":"userId",
"@having":"max(id)>=100"](http://apijson.cn:8080/get/{"[]":{"count":10,"Moment":{"@column":"userId,max(id)","@group":"userId","@having":"max(id)>=100"}}})
还可以指定函数返回名:
["@column":"userId,max(id):maxId",
"@group":"userId",
"@having":"maxId>=100"](http://apijson.cn:8080/get/{"[]":{"count":10,"Moment":{"@column":"userId,max(id):maxId","@group":"userId","@having":"maxId>=100"}}})
⑥ 从pictureList获取第0张图片:
["@position":0, //这里@position为自定义关键词
"firstPicture()":"getFromArray(pictureList,@position)"](http://apijson.cn:8080/get/{"User":{"id":38710,"@position":0,"firstPicture()":"getFromArray(pictureList,@position)"}})
