c - 从 csv 读取数据时出现问题

Question

我正在编写 c 代码，需要读取 csv 数据并将其输入到结构中。不可否认，我都更熟悉 C++，并且之前没有做过太多从文件读取的工作，所以我可能会错过一些非常明显的东西。但是，当我在应该加载数据后检查结构数组时，我得到了正确的行数，但除了第二行之外的所有行都是空白的 - 而且出于某种原因，那一行只有一张笑脸......

这是我的代码:

void load_items(){
char file_name[20], buffer[MAX_LINE_LENGTH];
FILE *file;
int i;

printf("Enter the file to load data from: ");       //data.csv for here
scanf("%s", file_name);

file=fopen(file_name,"r");

if(file==NULL)
{
    printf("Can't open %s\n",file_name);
    //exit(EXIT_FAILURE);
}
else {
    printf("Congrats! you opened %s as your data source!\n", file_name);        //test to make sure opened file
    while((fgets(buffer, sizeof(buffer),file)) !=NULL)          //while the line isn't blank
    {
        scanf(buffer,"%s,%s,%d,%d",&places[i].name,&places[i].category,&places[i].x,&places[i].y);      //enter data into proper place
        printf("|%-23s|%-20s\t| ( %d, %d) |\n",places[i].name, places[i].category, places[i].x,places[i].y);    //test to see data
        i++;
    }
}
fclose(file);
}

这是它正在读取的信息的样子:

|                       |                       | ( 0, 0) |

如果不是那个奇怪的笑脸，我会认为它只是没有读取任何内容，或者没有将其传输到正确的结构中，但事实上我很困惑。非常欢迎任何建议，感谢您的宝贵时间!

尝试使用 fscanf 从文件读取而不是 scanf，并使用 %[^,](读取除 ',' 之外的所有内容) %s。

Codesnip: while(fscanf(文件, "%[^,],%[^,],%d,%d", &places[i].name, &places[i].category, &places[ i].x, &places[i].y) == 4)
