在使用demo工程的时候,遇到以下几个问题:
1.64位系统因指针占8个字节导致地址错位,可以加以说明
2.csonFree函数释放CSON_TYPE_LIST类型时,如果是csonIsBasicListModel类型,应为*tmpNode = (int)((p->obj)); ,而不是 *tmpNode = (int)(&(p->obj));
3.csonEncode函数在csonEncodeObject时,csonEncodeString直接使用了现有的地址,没有新分配地址
导致cJSON_Delete(json);时,会释放不是本次申请的地址,导致运行时出错malloc(): memory corruption (fast):
cson.c文件中的第630行tmpNode = (int)(&(p->obj));,应改为tmpNode = (int)(p->obj);
项目中遇到客户使用json字段不规范,”level-position“不能作为结构体元素名称,所以无法在不修改cson源码的基础上使用cson。
我的修改是:增加以下类似的宏定义即可使用
/**
使用:CSON_MODEL_INT2(MQTTSubTopicOrientationRecvPayload_s, level_position, "level-position"),
首先感谢分享代码,json中的bool类型无法解析正确,每次都是0,不管数据是true还是false。
很好用,支持作者,但是有点问题,映射地址的时候没考虑64位系统😂,还有一些地方有bug,你有国内邮箱么,我发给你我修改之后的对比报告,我这儿不方便推送分支给你
struct test
{
char id;
short num;
int max;
double value;
char *name;
struct subtest sub[10];<--------------------!!!
CsonList *list;
char *str[2];
CsonList *charList;
CsonList *strList;
};
如果支持了,可能我要没研究透。
比如:服务器下发命令的json最多支持3个命令,例如:
{
"pir_enable": true,
"led_enable": false,
"wifi_enable": true;
}
但是有的时候可能只发送,其中两种,或者只发送一种:
例如:
{
"pir_enable": true,
"led_enable": false,
}
或者
{
"led_enable": false,
"wifi_enable": true;
}
