前面提到，那个C源程序有点问题，其实就是HTML标签没有安装XHTML的规范来写，现在贴出更改后的mian函数

int main(void)
{
char *lenstr;
char input[MAXINPUT], data[MAXINPUT];
long len;
//printf("%s%c%c\n\n","Content-Type:text/html;charset=iso-8859-1",13,10);
printf("Content-Type:text/html\n\n");
printf("<html>\n");
printf("<head>\n<title>Response</title>\n</head>\n");
printf("<body>\n");
lenstr = getenv("CONTENT_LENGTH");
if(lenstr == NULL || sscanf(lenstr,"%ld",&len)!=1 || len > MAXLEN)
printf("Error in invocation - wrong FORM probably.\n");
else {
FILE *f;
fgets(input, len+1, stdin);
unencode(input+EXTRA, input+len, data);
f = fopen(DATAFILE, "a");
if(f == NULL)
printf("Sorry, cannot store your data.\n");
else
fputs(data, f);
fclose(f);
printf("Thank you! Your contribution has been stored.\n");
}
printf("</body>\n</html>\n");
return 0;
}
