Define the data structure for JSON. 25 | 2. Define the property description table for data structure. 26 | 3. Call cson api to decode or encode. 27 | 28 | ## Dependence 29 | https://github.com/akheron/jansson.git 30 | https://github.com/DaveGamble/cJSON.git 31 | 32 | ## Demo 33 | Here is a JSON with various data types. eg. Interger, String, Real, Boolean, Object, and Array. 34 | We're going to decode and encode it by cson. 35 | 36 | ``` json 37 | { 38 | "name":"jay zhou", 39 | "creater":"dahuaxia", 40 | "songNum":2, 41 | "songList":[ 42 | { 43 | "songName":"qilixiang", 44 | "signerName":"jay zhou", 45 | "albumName":"qilixiang", 46 | "url":"www.kugou.com", 47 | "duration":200, 48 | "paid":false, 49 | "price":6.6600000000000001, 50 | "lyricNum":2, 51 | "lyric":[ 52 | { 53 | "time":1, 54 | "text":"Sparrow outside the window" 55 | }, 56 | { 57 | "time":10, 58 | "text":"Multi mouth on the pole" 59 | } 60 | ] 61 | }, 62 | { 63 | "songName":"dongfengpo", 64 | "signerName":"jay zhou", 65 | "albumName":"dongfengpo", 66 | "url":"music.qq.com", 67 | "duration":180, 68 | "paid":true, 69 | "price":0.88, 70 | "lyricNum":2, 71 | "lyric":[ 72 | { 73 | "time":10, 74 | "text":"A sad parting, standing alone in the window" 75 | }, 76 | { 77 | "time":20, 78 | "text":"I'm behind the door pretending you're not gone" 79 | } 80 | ] 81 | } 82 | ], 83 | "extData":{ 84 | "a":999, 85 | "b":1.05 86 | } 87 | } 88 | ``` 89 | 90 | ### 1. Define the data structure for JSON. 91 | Even if you don't use cson, you usually need to do like this. 92 | 93 | #### Attention 94 | - String must be declared as char*. 95 | - Array must be declared as pointer. 96 | - Declare additional properties to hold the array size for every array property. 97 | - The structure property name must be the same as the JSON field name. 98 | 99 | ``` c 100 | typedef struct { 101 | int time; 102 | char* text; /* String must be declared as char* */ 103 | } Lyric; 104 | 105 | typedef struct { 106 | char* songName; 107 | char* signerName; 108 | char* albumName; 109 | char* url; 110 | int duration; 111 | int paid; 112 | double price; 113 | size_t lyricNum; /* Declare additional properties to hold the array size */ 114 | Lyric* lyric; /* Array must be declared as pointer */ 115 | } SongInfo; 116 | 117 | typedef struct { 118 | int a; 119 | double b; 120 | } ExtData; 121 | 122 | typedef struct { 123 | char* name; 124 | char* creater; 125 | size_t songNum; 126 | SongInfo* songList; 127 | ExtData extData; 128 | } PlayList; 129 | ``` 130 | 131 | ### 2. Define the property description table for data structure. 132 | Use following definitions to help you describe the structure. 133 | - _property_int(type, field) 134 | - _property_real(type, field) 135 | - _property_bool(type, field) 136 | - _property_string(type, field) 137 | - _property_obj(type, field, tbl) 138 | - _property_array_object(type, field, tbl, arrayType, countfild) # I know it's a little cumbersome, I'm trying to simplify it. 139 | - _property_array_int(type, field, arrayType, countfild) 140 | - _property_array_string(type, field, arrayType, countfild) 141 | - _property_array_real(type, field, arrayType, countfild) 142 | - _property_array_bool(type, field, arrayType, countfild) 143 | 144 | Args notes: 145 | - type: type of data structure 146 | - field: property name 147 | - tbl: description table of the property type. use when object or object array 148 | - arrayType: type of the array (Used to calculate size when dynamically get array memory) 149 | - countfild: property to save array size 150 | 151 | You can also use macro definitions with extended parameters, the range of args is _ex_args_nullable, _ex_args_exclude_decode, _ex_args_exclude_encode and thire combinations. 152 | - #define _ex_args_nullable (0x01) //continue parse or encode when the field exception occurred. Default is "ON". 153 | - #define _ex_args_exclude_decode (0x02) //do not parse the field. 154 | - #define _ex_args_exclude_encode (0x04) //do not encode the field. 155 | - #define _ex_args_all (_ex_args_nullable | _ex_args_exclude_decode | _ex_args_exclude_encode) 156 | 157 | - _property_int_ex(type, field, args) 158 | - _property_real_ex(type, field, args) 159 | - _property_bool_ex(type, field, args) 160 | - _property_string_ex(type, field, args) 161 | - _property_obj_ex(type, field, tbl, args) 162 | - _property_array_ex(type, field, tbl, subType, count, args) 163 | - _property_array_object_ex(type, field, tbl, subType, count, args) 164 | - _property_array_int_ex(type, field, subType, count, args) 165 | - _property_array_string_ex(type, field, subType, count, args) 166 | - _property_array_real_ex(type, field, subType, count, args) 167 | - _property_array_bool_ex(type, field, subType, count, args) 168 | 169 | ``` c 170 | /* description for Lyric */ 171 | reflect_item_t lyric_ref_tbl[] = { 172 | _property_int(Lyric, time), 173 | _property_string(Lyric, text), 174 | _property_end() 175 | }; 176 | 177 | /* description for SongInfo */ 178 | reflect_item_t song_ref_tbl[] = { 179 | _property_string(SongInfo, songName), 180 | _property_string(SongInfo, signerName), 181 | _property_string(SongInfo, albumName), 182 | _property_string(SongInfo, url), 183 | _property_int(SongInfo, duration), 184 | _property_bool(SongInfo, paid), 185 | _property_real(SongInfo, price), 186 | _property_int(SongInfo, lyricNum), 187 | _property_array(SongInfo, lyric, lyric_ref_tbl, Lyric, lyricNum), /* Lyric: type of array; lyricNum: property to save array size */ 188 | _property_end() 189 | }; 190 | 191 | /* description for ExtData */ 192 | reflect_item_t ext_data_ref_tbl[] = { 193 | _property_int(ExtData, a), 194 | _property_real(ExtData, b), 195 | _property_end() 196 | }; 197 | 198 | /* description for PlayList */ 199 | reflect_item_t play_list_ref_tbl[] = { 200 | _property_string(PlayList, name), 201 | _property_string(PlayList, creater), 202 | _property_int(PlayList, songNum), 203 | _property_array(PlayList, songList, song_ref_tbl, SongInfo, songNum), 204 | _property_obj(PlayList, extData, ext_data_ref_tbl), 205 | _property_end() 206 | }; 207 | ``` 208 | 209 | ### 3. Call cson api to decode or encode. 210 | ``` c 211 | PlayList playList; 212 | 213 | /* Decode */ 214 | csonJsonStr2Struct(jStr, &playList, play_list_ref_tbl); 215 | 216 | /* Encode */ 217 | char* jstrOutput; 218 | csonStruct2JsonStr(&jstrOutput, &playList, play_list_ref_tbl); 219 | ``` 220 | 221 | ## Restrict 222 | - Multidimensional arrays are not supported. 223 | - Cjson is used by default.

注意:当某个字段在json中被定义为数组时，那么该字段在结构体中要被声名为指针，并且增加数组size的字段。 84 | * 85 | * 2）为了C语言能够像java中通过反射来操作结构体中的属性，我们需要先为每个结构体定义一个用于查找结构体属性的“反射表”， 86 | * 即play_list_ref_tbl，ext_data_ref_tbl，song_ref_tbl，lyric_ref_tbl。 87 | * 有了这个反射表，我们可以迭代访问数组元素。不仅可以帮助我们完成json解析，当我们想要输出对象各属性值、或是释放 88 | * 指针指向的堆内存时也很有用。 89 | * 90 | * TODO:目前反射表的结构有些复杂，虽然提供了宏定义让它用来稍稍方便一些。需要对该结构做出优化。 91 | * 92 | * 3）正确的完成上面两步，解析工作其实基本上就要完成了。只要再调用csonJsonStr2Struct，所有的属性就都会正确的赋值到结构体。 93 | * 94 | */ 95 | 96 | 97 | /* 98 | Step1:定义与json相对应的数据结构 99 | */
