用 C 语言写的简单的 CGI 访问计数器程序，用文件保存的计数，我觉得比数据库高效一点吧，呵呵。
/* counter.c * Heihaier <admin@heiher.info> */ #include <stdio.h> #include <stdlib.h> int main(int argc, char * argv[]) { unsigned long long int counter = 0; FILE * f = NULL; char file[256]; printf("Content-type: text/html;\n\n"); char * query = getenv("QUERY_STRING"); if(NULL == query) goto error; snprintf(file, 256, "./data/%s", query); f = fopen(file, "rw+"); if(NULL == f) goto error; fread(&counter, sizeof(unsigned long long int), 1, f); printf("document.write(\"<b>%llu</b>\");", ++counter); fseek(f, 0, SEEK_SET); fwrite(&counter, sizeof(unsigned long long int), 1, f); fclose(f); return 0; error: return -1; }
Over!
