我想要做的是读取json格式文件并修改它，然后将修改后的内容写入文件。

55 cJSON *root,*basicpara;

56 char *out;

57

58 root = dofile("basicparameter.cfg");

59 out = cJSON_Print(root);

60 printf("before modify:%s\n",out);

61 free(out);

62 basicpara = cJSON_GetObjectItem(root,"basicparameter");

63 cJSON_GetObjectItem(basicpara,"mode")->valueint = 0;

64 cJSON_GetObjectItem(basicpara,"TimeoutPoweron")->valueint = 10;

65

66 out = cJSON_Print(root);

67 printf("after modify:%s\n",out);

68 free(out);

69 //write_file("basicparameter.cfg",out);

70 cJSON_Delete(root);我很困惑为什么两个内容都是一样的......

before modify:{

"basicparameter": {

"mode": 1,

"nBefore": 2,

"nAfter": 2,

"LuxAutoOn": 50,

"LuxAutoOff": 16,

"TimeoutPoweron": 30

}

}

after modify:{

"basicparameter": {

"mode": 1,

"nBefore": 2,

"nAfter": 2,

"LuxAutoOn": 50,

"LuxAutoOff": 16,

"TimeoutPoweron": 30

}

}
