java - 无法在 Jersey 中获取 POST 请求的有效负载

Question

我需要恢复表单 POST 请求的整个有效负载，将其发送回接收方(PayPal 要求将此作为验证程序)。我尝试了几种方法，但总是收到相同的警告，但没有有效负载:

Warning:   A servlet request to the URI http://localhost:8080/ipnlistener contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.

这是监听器的代码

@POST
@Path("/ipnlistener")
public Response testIpn(String t) {  
   System.out.println(t);
   return Response.ok().build();
}

我尝试添加不同的 Consumes 注释但没有任何变化。当然，使用 FormParam 注释我可以检索单个字段，但我确实需要请求的整个主体。

我也试过以下

public Response testIpn(@Context HttpServletRequest req) throws IOException {  
    BufferedReader reader= req.getReader();
    String sCurrentLine;
    while ((sCurrentLine = reader.readLine()) != null) {
        System.out.println(sCurrentLine);
    }

   return Response.ok().build();
}

但是我得到了错误

getInputStream() has already been called for this request

我认为您可以将以下代码添加到您的文件中:

 @Context  
 private HttpServletRequest request; 

HttpServletRequest 包含请求的整个主体!
