Breakpoint 1, need_to_parse_chunked_data (data=0xbffddbbc "a\r\n\037\213\b", len=15, buf=0xbffbdbbc "") at http.c:281 281 char strlength[10]={0}; (gdb) n 283 char * temp = buf; (gdb) 284 int total =0, length = 0, nBytes = 0; (gdb) 286 pTemp = strstr(pStart, "\r\n"); (gdb) n 287 if( NULL == pTemp ) (gdb) p data $1 = 0xbffddbbc "a\r\n\037\213\b" 这个数据包其实有1209个字节,但子函数里就只能看到这么一点点,我怀疑就是这里出问题了,但我又没有好的办法。gzip 文件中时包好多的0字符串,不知道有影响没 (gdb)
