ERR_INVALID_CHUNKED_ENCODING用于HTTP服务器的分块传输编码

Question

我的任务是使用分块传输编码实现简单的HTTP服务器。 这是读取请求并向客户端发送响应的函数。

 static int serve_request(int sock, struct conf_arg *arg, char version[])
    {
        int html;
        char buf[MAX_MSG];
        const unsigned chunk = (unsigned)CHUNK_SIZE;
        char tempbuf[CHUNK_SIZE + 3];
        ssize_t size;
        ssize_t bytes_read;

        strcpy(buf, arg->root);
        if(buf[strlen(buf) - 1] == '/')
            strcat(buf, arg->defdoc);
        html = open(buf, O_RDONLY);
        if (html == -1) {
            perror("Error in opening file");
            not_found(sock, version);
            return -1;
        }
        good_responce(sock, version); 
        size = lseek(html, 0, SEEK_END);
        lseek(html, 0, SEEK_SET);
        printf("SIZE:%d\n", (int)size);
        bytes_read = read(html, buf, size);
        while (bytes_read > chunk) {
            sprintf(tempbuf, "%x\r\n", (int)chunk);
            write(sock, tempbuf, strlen(tempbuf));
            write(sock, buf, chunk);
            write(sock, "\r\n", 2);
            bytes_read -= chunk;
        }
        sprintf(tempbuf, "%x\r\n", (int)bytes_read);
        printf("LAST PART:%d\n", (int)bytes_read);
        write(sock, tempbuf, strlen(tempbuf));
        write(sock, buf, bytes_read);
        write(sock, "\r\n", 2);
        strcpy(tempbuf, "0\r\n\r\n");
        write(sock, tempbuf, strlen(tempbuf));
        close(html);

        return 0;
    }

当我尝试使用我的服务器打开简单站点时，我收到错误：ERR_INVALID_CHUNKED_ENCODING。所以我希望你能帮我找到问题。
