Question

这可能是个愚蠢的问题，但我想确定。

如果你有这样简单的html表单：

  <form action='/requestlogger' method='post'>
    <input type='hidden' name='field1' value='fo' />
    <input type='hidden' name='field2' value='bar'/>
    <input type='hidden' name='field3' value='baz'/>
    <input type='submit'/>
  </form>

然后进行提交，然后浏览器生成如下请求：

POST http://localhost:9090/requestlogger HTTP/1.1
Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*

field1=fo&field2=bar&field3=baz

我很好奇我是否可以从servlet捕获这些原始数据，所以我写了测试方法：

@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) {
    try {
        Writer out = resp.getWriter();
        BufferedReader br = new BufferedReader(req.getReader());
        String read = br.readLine();
        while(read != null) {
            out.write(read);
            read = br.readLine();
        }
        br.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

但我只得到了：

field1=fo&field2=bar&field3=baz

当我想到这一点时，这正是我想要得到的，因为webserver（tomcat）处理复杂的东西，我准备好使用HttpServletRequest，所有的头数据都可以通过API（req.getContentLength（），req.getCookies （），req.getHeaderNames（）等。）

所以我认为你无法从servlet访问“完整”的RAW请求数据？或者我错过了什么？

由于

是否可以从servlet访问RAW servlet请求？
