我用zlib的 deflateInit2压缩的字符，浏览器显示错误

我要思考

int main(int argc, char **argv) {     int err;     unsigned have;     z_stream strm;     char in[CHUNK]  = "The most straightforward technique turns out to be the fastest for*      most input files: try all possible    strings is inspired from that of Rabin & Karp. A brute force approach*      is used to find longer strings when a small match has been found.*      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze*      (by Leonid Broukhis).";     char out[CHUNK];     strm.zalloc   = Z_NULL;     strm.zfree    = Z_NULL;     strm.opaque   = Z_NULL;     strm.avail_in = 0;     strm.next_in  = Z_NULL;     err = deflateInit2(&strm, 8, Z_DEFLATED, -MAX_WBITS, MAX_MEM_LEVEL, Z_DEFAULT_STRATEGY);     if(err != Z_OK)     {         printf("deflateInit error: %d\r\n", err);         return 0;     }         strm.avail_in = strlen(in);     strm.next_in  = in;     do {             strm.avail_out = CHUNK;             strm.next_out  = out;             err = deflate(&strm, Z_FINISH);             assert(err != Z_STREAM_ERROR);  /* state not clobbered */             switch (err) {             case Z_NEED_DICT:                 err = Z_DATA_ERROR;     /* and fall through */             case Z_DATA_ERROR:             case Z_MEM_ERROR:                 (void)inflateEnd(&strm);                 return err;             }             have = CHUNK - strm.avail_out;             printf("in = %d\r\nout = %s\r\nhave = %d\r\nstrm.total_out = %d\r\n", strlen(in), out, have, strm.total_out);         } while (strm.avail_out == 0);         assert(strm.avail_in == 0);     /* all input will be used */     deflateEnd(&strm);     return 1; }

这个是我根据官方的例子代码 改过来的。当http server的  字符串压缩。 我在HTTP头信息里面 加上 了

opera 显示一堆乱码、 大家帮我看看 什么问题
