# APIJSON [English Document](https://github.com/TommyLemon/APIJSON/blob/master/README(English).md) APIJSON是一种JSON传输结构协议。
客户端可以定义任何JSON结构去向服务端发起请求，服务端就会返回对应结构的JSON字符串，所求即所得。
一次请求任意结构任意数据，方便灵活，不需要专门接口或多次请求。
支持增删改查、模糊搜索、远程函数调用等。还能去除重复数据，节省流量提高速度！
从此HTTP传输JSON数据没有接口，更不需要文档！
客户端再也不用和服务端沟通接口或文档问题了！再也不会被文档各种错误坑了！
服务端再也不用为了兼容旧版客户端写新版接口和文档了！再也不会被客户端随时随地没完没了地烦了！举个栗子（查询类似微信朋友圈动态列表）: ### 请求：

{
"[]": { //请求一个array
"page": 1, //array条件
"count": 2,
"User": { //请求查询名为User的table，返回名为User的JSONObject
"sex": 0 //object条件
},
"Moment": {
"userId@": “/User/id” //缺省依赖路径，从同级object的路径开始
},
"Comment[]": { //请求一个名为Comment的array
"page": 0,
"count": 3,
"Comment": {
"momentId@": “[]/Moment/id” //完整依赖路径
}
}
}
}

② 从pictureList获取第0张图片作为头像；
{
"pictureList":["url0","url1"],
"@position":0, //这里@position为自定义关键词
"head()":"get(Collection:pictureList,Object:@position)"
}
... ## 对比传统HTTP传输方式开发流程 | 传统方式 | APIJSON -------- | ------------ | ------------ 接口传输 | 等服务端编辑接口，然后更新文档，客户端再按照文档编辑请求和解析代码 | 客户端按照自己的需求编辑请求和解析代码。没有接口，更不需要文档！客户端再也不用和服务端沟通接口或文档问题了！兼容旧版 | 服务端增加新接口，用v2表示第2版接口，然后更新文档 | 什么都不用做！客户端请求 | 传统方式 | APIJSON -------- | ------------ | ------------ 要求 | 客户端按照文档在对应url后面拼接键值对 | 客户端按照自己的需求在固定url后拼接JSON 结构 | base_url/lowercase_table_name?key0=value0&key1=value1...
¤tUserId=100&loginPassword=1234

其中currentUserId和loginPassword只在请求部分接口时需要 | base_url/{TableName0:{key0:value0, key1:value1 ...}, TableName1:{...}...
, currentUserId:100, loginPassword:1234}

其中currentUserId和loginPassword只在请求部分接口时需要 URL | 不同的请求对应不同的url | 相同的请求方法(GET，POST等)都用同一个url 键值对 | key=value | key:value 服务端操作 | 传统方式 | APIJSON -------- | ------------ | ------------ 解析和返回 | 取出键值对，把键值对作为条件用预设的的方式去查询数据库，最后封装JSON并返回给客户端 | 把RequestParser#parse方法的返回值返回给客户端就行返回JSON结构的设定方式 | 由服务端设定，客户端不能修改 | 由客户端设定，服务端不能修改客户端解析 | 传统方式 | APIJSON -------- | ------------ | ------------ 查看方式 | 查文档或等请求成功后看log | 看请求就行，所求即所得。也可以等请求成功后看log 方法 | 解析JSONObject | 可以用JSONResponse解析JSONObject或传统方式客户端对应不同需求的请求 | 传统方式 | APIJSON -------- | ------------ | ------------ User | http://localhost:8080/get/user?id=1 | [http://localhost:8080/get/{"User":{"id":1}}](http://139.196.140.118:8080/get/{"User":{"id":38710}}) Moment和对应的User | 分两次请求
Moment: http://localhost:8080/get/moment?userId=1
User: http://localhost:8080/get/user?id=1 | [http://localhost:8080/get/{"Moment":{"id":1}, "User":{"id@":"Moment/userId"}}](http://139.196.140.118:8080/get/%7B%22Moment%22%3A%7B%22id%22%3A15%7D%2C%22User%22%3A%7B%22id%40%22%3A%22Moment%252FuserId%22%7D%7D) User列表 | http://localhost:8080/get/user/list?page=0&count=3&sex=0 | [http://localhost:8080/get/{"[]":{"page":0, "count":3, "User":{"sex":0}}}](http://139.196.140.118:8080/get/{"[]":{"page":0,"count":3,"User":{"sex":0}}}) Moment列表，每个Moment包括发布者User和前3条Comment | Moment里必须有User的Object和Comment的Array
http://localhost:8080/get/moment/list?page=0&count=3&commentCount=3 | [http://localhost:8080/get/{"[]":{"page":0, "count":3, "Moment":{}, "User":{"momentId@":"/Moment/id"}, "[]":{"count":3, "Comment":{"momentId@":"[]/Moment/id"}}}}](http://139.196.140.118:8080/get/%7B%22%5B%5D%22%3A%7B%22Moment%22%3A%7B%7D%2C%22User%22%3A%7B%22id%40%22%3A%22%252FMoment%252FuserId%22%7D%2C%22Comment%5B%5D%22%3A%7B%22Comment%22%3A%7B%22momentId%40%22%3A%22%255B%255D%252FMoment%252Fid%22%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%7D) 1个User发布的Moment列表，每个Moment包括发布者User和前3条Comment | http://localhost:8080/get/moment/list?page=0&count=3&commentCount=3&userId=1 | 有以下几种方法:
①把以上请求里的"Moment":{}, "User":{"momentId@":"/Moment/id"}改为["Moment":{"userId":1}, "User":{"id":1}](http://139.196.140.118:8080/get/%7B%22%5B%5D%22%3A%7B%22Moment%22%3A%7B%22userId%22%3A38710%7D%2C%22User%22%3A%7B%22id%22%3A38710%7D%2C%22%5B%5D%22%3A%7B%22Comment%22%3A%7B%22momentId%40%22%3A%22%255B%255D%252FMoment%252Fid%22%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%7D)

②或这样省去4条重复User
[http://localhost:8080/get/{"User":{"id":1}, "[]":{"page":0, "count":3, "Moment":{"userId":1}, "[]":{"count":3, "Comment":{"momentId@":"[]/Moment/id"}}}}](http://139.196.140.118:8080/get/%7B%22User%22%3A%7B%22id%22%3A38710%7D%2C%22%5B%5D%22%3A%7B%22Moment%22%3A%7B%22userId%22%3A38710%7D%2C%22%5B%5D%22%3A%7B%22Comment%22%3A%7B%22momentId%40%22%3A%22%255B%255D%252FMoment%252Fid%22%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%7D)

③如果User之前已经获取到了，还可以这样省去所有重复User
[http://localhost:8080/get/{"[]":{"page":0, "count":3, "Moment":{"userId":1}, "[]":{"count":3, "Comment":{"momentId@":"[]/Moment/id"}}}}](http://139.196.140.118:8080/get/%7B%22%5B%5D%22%3A%7B%22Moment%22%3A%7B%22userId%22%3A38710%7D%2C%22%5B%5D%22%3A%7B%22Comment%22%3A%7B%22momentId%40%22%3A%22%255B%255D%252FMoment%252Fid%22%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%2C%22count%22%3A3%2C%22page%22%3A0%7D%7D) 服务端对应不同请求的返回结果 | 传统方式 | APIJSON -------- | ------------ | ------------ User | {"status":200, "message":"success", "data":{"id":1, "name":"xxx"...}} | {"status":200, "message":"success", "User":{"id":1, "name":"xxx"...}} User和对应的Moment | 分别返回两次请求的结果
User: {"status":200, "message":"success", "data":{"id":1, "name":"xxx"...}}
Moment: {"status":200, "message":"success", "data":{"id":1, "name":"xxx"...}} | {"status":200, "message":"success", "User":{"id":1, "name":"xxx"...}, "Moment":{"id":1, "content":"xxx"...}} User列表 | {"status":200, "message":"success", "data":[{"id":1, "name":"xxx"...}, {"id":2...}...]} | {"status":200, "message":"success", "[]":{"0":{"User":{"id":1, "name":"xxx"...}}, "1":{"User":{"id":2...}}...}} Moment列表，每个Moment包括发布者User和前3条Comment | {"status":200, "message":"success", "data":[{"id":1, "content":"xxx"..., "User":{...}, "Comment":[...]}, {"id":2...}...]} | {"status":200, "message":"success", "[]":{"0":{"Moment":{"id":1, "content":"xxx"...}, "User":{...}, "[]":{"0":{"Comment":{...}...}}}, "1":{...}...}} 1个User发布的Moment列表，每个Moment包括发布者User和前3条Comment | {"status":200, "message":"success", "data":[{"id":1, "content":"xxx"..., "User":{...}, "Comment":[...]}, {"id":2...}...]} | 以上不同请求方法的结果:
①{"status":200, "message":"success", "[]":{"0":{"User":{"id":1, "name":"xxx"...}, "Moment":{...}, "[]":{"0":{"Comment":{...}...}}}, "1":{...}...}}

②{"status":200, "message":"success", "User":{...}, "[]":{"0":{"Moment":{"id":1, "content":"xxx"...}, "[]":{"0":{"Comment":{...}...}}}, "1":{...}...}}

③{"status":200, "message":"success", "[]":{"0":{"Moment":{"id":1, "content":"xxx"...}, "[]":{"0":{"Comment":{...}...}}}, "1":{...}...}} ## 使用方法 ### 1.下载后解压APIJSON工程 Clone or download > Download ZIP > 解压到一个路径并记住这个路径。 #### 你可以跳过步骤2和步骤3，用我的服务器IP地址 139.196.140.118:8080 来测试服务端对客户端请求的返回结果。 ### 2.导入MySQL table文件服务端需要MySQL Server和MySQLWorkbench，没有安装的都先下载安装一个。
我的配置是Windows 7 + MySQL Community Server 5.7.16 + MySQLWorkbench 6.3.7 和 OSX EI Capitan + MySQL Community Server 5.7.16 + MySQLWorkbench 6.3.8，其中系统和软件都是64位的。启动MySQLWorkbench > 进入一个Connection > 点击Server菜单 > Data Import > 选择刚才解压路径下的APIJSON-Master/table > Start Import > 刷新SCHEMAS, 左下方sys/tables会出现添加的table。 ### 3.用Eclipse for JavaEE或IntellIJ IDEA Ultimate运行服务端工程如果以上编辑器一个都没安装，运行前先下载安装一个。
我的配置是Windows 7 + JDK 1.7.0_71 + Eclipse 4.6.1 + IntellIJ 2016.3 和 OSX EI Capitan + JDK 1.8.0_91 + Eclipse 4.6.1 + IntellIJ 2016.2.5 #### Eclipse for JavaEE 1.导入
File > Import > Maven > Existing Maven Projects > Next > Browse > 选择刚才解压路径下的APIJSON-Master/APIJSON(Server)/APIJSON(Eclipse_JEE) > Finish 2.运行
Run > Run As > Java Application > 选择APIJSONApplication > OK #### IntellIJ IDEA Ultimate 1.导入
Open > 选择刚才解压路径下的APIJSON-Master/APIJSON(Server)/APIJSON(Idea) > OK 2.运行
Run > Run APIJSONApplication ### 4.用ADT Bundle或Android Studio运行客户端工程可以跳过这个步骤，直接下载下方提供的客户端App。如果以上编辑器一个都没安装，运行前先下载安装一个。
我的配置是Windows 7 + JDK 1.7.0_71 + ADT Bundle 20140702 + Android Studio 2.2 和 OSX EI Capitan +（JDK 1.7.0_71 + ADT Bundle 20140702）+（JDK 1.8.0_91 + Android Studio 2.1.2），其中系统和软件都是64位的。 #### ADT Bundle 1.导入
File > Import > Android > Existing Android Code Into Workspace > Next > Browse > 选择刚才解压路径下的APIJSON-Master/APIJSON(Android)/APIJSON(ADT) > Finish 2.运行
Run > Run As > Android Application #### Android Studio 1.导入
Open an existing Android Studio project > 选择刚才解压路径下的APIJSON-Master/APIJSON(Android)/APIJSON(AndroidStudio) > OK 2.运行
Run > Run app ### 5.操作客户端App 选择发送APIJSON请求并等待显示结果。
如果默认url不可用，修改为一个可用的，比如正在运行APIJSON服务端工程的电脑的IPV4地址，然后点击查询按钮重新请求。 ## 下载试用客户端App [APIJSONClientApp.apk](http://files.cnblogs.com/files/tommylemon/APIJSONApp.apk) ### 关于APIJSON如果你有任何问题或建议，都可以发我邮件 tommylemon@qq.com. ## 更新日志 [https://github.com/TommyLemon/APIJSON/commits/master](https://github.com/TommyLemon/APIJSON/commits/master) ## 欢迎Star，欢迎Fork [https://github.com/TommyLemon/APIJSON](https://github.com/TommyLemon/APIJSON) # APIJSON，让接口见鬼去吧！
