(json-c学习4) linux c语言封装json对象和数组的组合（纯代码)

头文件什么的都在首篇(json-c学习1) linux c语言解析json数组（纯代码），这里只写一个简单的函数： 

238 void PkgBodyArrayFunction(void)
239 {
240     //封装成如下形式的json内容：
241     /*
242         {
243             "loop_number": 1,
244             "sensor_address:1,
245             "body":
246             [
247                 {"loop_number":2,"sensor_address":3"},
248                 {"loop_number":4,"sensor_address":5"},
249             ]
250         }
251     */
252     json_object *pValue = NULL;
253     json_object *pObjectSerPro = NULL;
254     char msg[400] = {0};
255     int loopNumber = 1;
256     int sensorAddress = 2;
257     SinglePointIdStruct array[2] = {{2,3},{4,5}};
258     //创建json对象
259     pObjectSerPro = json_object_new_object();
260     //添加内容
261     pValue = json_object_new_int(loopNumber);
262     json_object_object_add(pObjectSerPro, LOOP_NUMBER, pValue);
263     pValue = json_object_new_int(sensorAddress);
264     json_object_object_add(pObjectSerPro, SENSOR_ADDRESS, pValue);
265
266     json_object *jarray = json_object_new_array();  //建数组
267     int i = 0;
268     for (i = 0;i < 2; i++)
269     {
270         json_object *pObj = json_object_new_object();
271         pValue = json_object_new_int(array[i].loopNumber);
272         json_object_object_add(pObj, LOOP_NUMBER, pValue);
273         pValue = json_object_new_int(array[i].sensorAddress);
274         json_object_object_add(pObj, SENSOR_ADDRESS, pValue);
275
276         json_object_array_add(jarray, pObj);  //将对象加入数组
277     }
278     json_object_object_add(pObjectSerPro, BODY, jarray);
279
280     memset(msg, 0, 400);
281     sprintf(msg, "%s", (char*)(json_object_to_json_string(pObjectSerPro)));
282
283     printf("msg = %s\n", msg);
284
285 }

main函数：

333 int main(void)
334 {
335     char *body = TestBodyFunction();
336     ParsingBodyFunction(body);
337     printf("=====================================================\n");
338     //struct json_object *array = TestArrayFunction();
339     char *array = TestArrayFunction();
340     ParsingArrayFunction(array);
341     printf("=====================================================\n");
342     char *str = "[{\"loop_number\":1, \"sensor_address\":2}]";
343     int len = strlen(str);
344     printf("len = %d\n", len);
345     PkgArrayFunction();
346     printf("=====================================================\n");
347     PkgJsonFunction();
348     printf("=====================================================\n");
349     PkgBodyArrayFunction();
350     printf("=====================================================\n");
351     PkgBodyJsonFuncton();
352     return 0;
353 }
354
355
