C 使用令牌从文件读取到不同的结构

C 使用令牌从文件读取到不同的结构,c,file,struct,token,C,File,Struct,Token,我有两个不同的结构,其中后面的是链表的一个节点 typedef struct following{ char nick[6]; int last_message; bool first_time; struct following *next; }following; typedef struct user{ char nick[6]; char name[26]; int n_messages;

我有两个不同的结构,其中
后面的
是链表的一个节点

typedef struct following{
    char nick[6];
    int last_message;
    bool first_time;
    struct following *next;
}following;

typedef struct user{                     
    char nick[6];
    char name[26];
    int n_messages;
    int n_following;
    int n_followers;
    following *arr_following;
    following *arr_unfollowed;
}user;
我必须通过读取以下文件来填充
用户
结构:

zsq4r Pseu Donym 3 1 2;zero7 2 true!
zero7 James Bond 4 3 3;zsq4r 3 true!zero7 4 false!MrPym 1 true!
MrPym A Perfect Spy 1 3 1;zsq4r 3 true!zero7 4 true!AlecS 1 true!
AlecS He Who Came from the Cold 1 0 1;
void read_from_file(hashtable *active_users, FILE *fp_active){
    const char *delimiter1 = "!";
    const char *delimiter2 = ";";
    char *last_token;
    char buffer[1540];
    while(fgets(buffer, 1540, fp_active)) {
        user *new_user = malloc(sizeof(user));
        last_token = strtok( buffer, delimiter2);
        while( last_token != NULL ){
            sscanf(last_token,"%s %[^\n] %d %d %d", new_user->nick, new_user->name, &new_user->n_messages, &new_user->n_following,
                   &new_user->n_followers);
            last_token = strtok( NULL, delimiter1);
        }
        insert(active_users, new_user);
    }
}
用“;”分隔的内容用于填充
用户
结构,用“!”分隔的内容用于填充后面的
结构

注意:文件每行的“第二个”元素将是用户的名称,最多可以是25个字符,并且可以用空格分隔。例如,“来自寒冷的人”是一个有效的名字

我试着这样填充它们:

zsq4r Pseu Donym 3 1 2;zero7 2 true!
zero7 James Bond 4 3 3;zsq4r 3 true!zero7 4 false!MrPym 1 true!
MrPym A Perfect Spy 1 3 1;zsq4r 3 true!zero7 4 true!AlecS 1 true!
AlecS He Who Came from the Cold 1 0 1;
void read_from_file(hashtable *active_users, FILE *fp_active){
    const char *delimiter1 = "!";
    const char *delimiter2 = ";";
    char *last_token;
    char buffer[1540];
    while(fgets(buffer, 1540, fp_active)) {
        user *new_user = malloc(sizeof(user));
        last_token = strtok( buffer, delimiter2);
        while( last_token != NULL ){
            sscanf(last_token,"%s %[^\n] %d %d %d", new_user->nick, new_user->name, &new_user->n_messages, &new_user->n_following,
                   &new_user->n_followers);
            last_token = strtok( NULL, delimiter1);
        }
        insert(active_users, new_user);
    }
}
尽管“last_token”变量在每个循环中都保存了从文件读取的字符串的正确部分,但我无法找到填充两个结构的方法,因为
sscanf
只填充
用户
结构的一部分


任何帮助都将不胜感激。

根据我设法解决问题的评论中的提示,将文件的内容更改为:

zero7;James Bond;2;1;0[MrPym;1;true](zero7;0;false)
MrPym;A Perfect Spy;1;0;1
zsq4r;Pseu Donym;3;1;2[zero7;2;true]
zero7;James Bond;4;3;3[zsq4r;3;true][zero7;3;false][MrPym;1;true]
MrPym;A Perfect Spy;1;3;1[zsq4r;3;true][zero7;4;true][AlecS;1;true]
AlecS;He Who Came from the Cold;1;0;1
因此,我使用以下代码将信息提取到不同的结构中:

void read_from_file(hashtable *active_users, hashtable *inactive_users, FILE *fp_active, FILE *fp_inactive){
    char m_bool[6];
    char *first_token;
    char *last_token;
    char buffer[1540];
    char buffer2[1540];
    while(fgets(buffer, 1540, fp_active)) {
        strcpy(buffer2, buffer);
        user *new_user = malloc(sizeof(user));
        new_user->arr_following = NULL;
        new_user->arr_unfollowed = NULL;
        last_token = strtok( buffer, "[");
        sscanf(last_token,"%[^;]; %[^;]; %d; %d; %d", new_user->nick, new_user->name, &new_user->n_messages, &new_user->n_following,
               &new_user->n_followers);
        last_token = strtok( NULL, "[");
        while(last_token != NULL){
            following *tmp_following = malloc(sizeof(following));
            sscanf(last_token," %[^;]; %d; %5s", tmp_following->nick, &tmp_following->last_message, m_bool);
            if(strcmp(m_bool, "true]") == 0)
                add(&new_user->arr_following, tmp_following->nick, tmp_following->last_message, true);
            else
                add(&new_user->arr_following, tmp_following->nick, tmp_following->last_message, false);
            last_token = strtok( NULL, "[");
        }
        first_token = strtok( buffer2, ")");
        while(first_token != NULL && strcmp(first_token, buffer2) != 0){
            following *tmp_following = malloc(sizeof(following));
            sscanf(first_token," %[^;]; %d; %5s", tmp_following->nick, &tmp_following->last_message, m_bool);
            if(strcmp(m_bool, "true]") == 0)
                add(&new_user->arr_unfollowed, tmp_following->nick, tmp_following->last_message, true);
            else
                add(&new_user->arr_unfollowed, tmp_following->nick, tmp_following->last_message, false);
            first_token = strtok( NULL, "(");
        }
        insert2(active_users, new_user);
    }
}

我必须为每行重新运行文件字符串2次,因为有3种类型的令牌,
;[(

@melpomene这只是为了节省空间,避免问题变得更大,如果需要的话,我可以更改…请做…@user3121023可能是这个%26[^\n]会更好吗?@user3121023我需要选择可以用空格分隔的用户名,我永远不知道它会有多长。我认为换行符是一个足够的结尾分隔符。为什么不使用分号来分隔每个字段呢?
zsq4r;Pseu Donym;3;1;2;zero7;2;true
-尽管我看到你在en有一个三元组的列表d、 可能采用JSON中的一个叶子:
zsq4r;Pseu Donym;3;1;2[zero7;2;true]
,其中可以使用
[]
以外的其他字符来包围数据,以及一组
[]
per triple。基本上,您可以设计格式,以便使用您希望用于解析的工具轻松解析。您可能应该阅读整行内容,然后使用或临时解析。
