5. json_object_to_json_string获取到的字串要不要释放 int main(int argc, char **argv) { struct json_object* obj; char *str; obj = json_object_new_object(); json_object_object_add(obj, "a", json_object_new_int(1)); json_object_object_add(obj, "b", json_object_new_int(2));...
```c const char *jsonStr = json_object_to_json_string(jsonObj); printf("%s\n", jsonStr); ``` 7.释放JSON对象: ```c json_object_put(jsonObj); ``` 需要注意的是,以上只是json-c库的基本用法示例,json-c库还提供了很多其他用来处理JSON数据的函数和结构体,可以根据具体需求进行使用。©...
printf("JSON: %s\n", json_object_to_json_string(json)); json_object_put(json); return 0; } ``` 在上述代码中,我们首先创建一个空的JSON对象`json`,然后使用`json_object_new_string`和`json_object_new_int`函数创建各个字段的值。接着,使用`json_object_object_add`函数将字段和值添加到JSON对...
