Url rewriting 主页的G-WAN URL重写不起作用

我正在尝试做一个网站主页的URL重写。下面是我的处理程序的简化版本

int init(int argc, char *argv[])
{
   u32 *states = (u32*)get_env(argv, US_HANDLER_STATES);
   *states =  (1 << HDL_AFTER_READ);
   return 0;
}

int main(int argc, char *argv[])
{
   xbuf_t *read_xbuf = (xbuf_t*)get_env(argv, READ_XBUF);
   xbuf_replfrto(read_xbuf, read_xbuf->ptr, read_xbuf->ptr + 16, " / ", " /?home ");
   return 255;
}

void clean(int argc, char *argv[]) 
{}

重写请求：

GET /?home HTTP/1.1
Host: localhost:8000
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive

重写之后，这就是结果

GET http://localhost:8000/

您忘记了

返回255main（）

函数中选择code>

请记住，连接处理程序返回代码具有以下含义：

return 255; // execute next connection step
return   0; // close connection

此外，即使它仍然为空，也必须在连接处理程序中声明一个

clean（）

函数：

void clean(int argc, char *argv[]) 
{}

最后，必须在

main（）

中测试处理程序状态

这为我们提供了以下测试代码：

这个问题在G-WAN版本4+上得到解决

我修改了我的示例代码。我得到了干净的，并返回了我的原始代码255。但还是一样的问题。我重写了上面的回复，添加了完整的（测试过的）源代码。还是一样的。我使用了你的代码，但我使用的是虚拟机。这可能会引起问题。今晚我将在家里尝试。重写后，我得到了“req_2:GET/？home HTTP/1”。但仍然没有结果。证明重写处理程序工作正常。现在检查日志文件，看看为什么不提供该文件（404：找不到？）。
