頭文件什麼的都在上篇(json-c學習1) linux c語言解析json數組（純代碼），這裏只寫一個簡單的函數：
209
210 int main(void)
211 {
212 char *body = TestBodyFunction();
213 ParsingBodyFunction(body);
214 printf("=====================================================\n");
215 //struct json_object *array = TestArrayFunction();
216 char *array = TestArrayFunction();
217 ParsingArrayFunction(array);
218 printf("=====================================================\n");
219 char *str = "[{\"loop_number\":1, \"sensor_address\":2}]";
220 int len = strlen(str);
221 printf("len = %d\n", len);
222 PkgArrayFunction();
223 return 0;
224 }
225
226
具體函數實現：
170 void PkgArrayFunction(void)
171 {
172 //封裝成如下形式的json內容：
173 /*
174 [
175 {"loop_number": 1, "sensor_address":1},
176 {"loop_number": 1, "sensor_address":1},
177 {"loop_number": 2, "sensor_address":1},
178 {"loop_number": 2, "sensor_address":1},
179 …
180 ]
181 */
182
183 SinglePointIdStruct array[10];
184 int i = 0;
185 for (i = 0; i < 10; i++)
186 {
187 array[i].loopNumber = i+5;
188 array[i].sensorAddress = i+10;
189 }
190 char *head = (char *)malloc(40*10*sizeof(char));
191 json_object *pValue = NULL;
192 json_object *pObjectSerPro = NULL;
193 json_object *jarray = json_object_new_array(); //建數組
194
195 for (i = 0; i < 10; i++)
196 {
197 json_object *pObj = json_object_new_object();
198 pValue = json_object_new_int(array[i].loopNumber);
199 json_object_object_add(pObj, LOOP_NUMBER, pValue);
200 pValue = json_object_new_int(array[i].sensorAddress);
201 json_object_object_add(pObj, SENSOR_ADDRESS, pValue);
202
203 json_object_array_add(jarray, pObj); //將對象加入數組
204 }
205 memset(head, 0, 40*10*sizeof(char));
206 sprintf(head, "%s", (char*)json_object_to_json_string(jarray));
207 printf("head = %s\n", head);
208 }
測試結果：
