Jersey request.getInputStream（）

Question

@POST 
@Path("/getphotos") 
@Produces(MediaType.TEXT_HTML) 
public String getPhotos() throws IOException{ 
    BufferedReader rd = new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8")); 
    String line; 
    while ((line = rd.readLine()) != null) { 
     System.out.println(line); 
    } 
    return "ok";   
} 

上面的代码用于我的服务器。 但是在这段代码中，字符串“line”没有任何值（总是） 代码有问题吗？

客户端代码

String message = "message"; 
    URL url = new URL(targetURL); 
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 

    urlConnection.setDoInput(true); 
    urlConnection.setDoOutput(true); 
    OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream()); 
    wr.write(message);

您可以手动泽西消耗的请求的数据，只要你有一个有效的句柄实际HttpServletRequest。在轻微侧面说明，请记住，你只能消耗请求主体一次：

@Context 
private HttpServletRequest request; 

@POST 
@Path("/") 
public Response consumeRequest() { 
    try { 
     final BufferedReader rd = new BufferedReader(new InputStreamReader(
       request.getInputStream(), "UTF-8")); 

     String line = null; 
     final StringBuffer buffer = new StringBuffer(2048); 

     while ((line = rd.readLine()) != null) { 
      buffer.append(line); 
     } 
     final String data = buffer.toString(); 
     return Response.ok().entity(data).build(); 
    } catch (final Exception e) { 
     return Response.status(Status.BAD_REQUEST) 
       .entity("No data supplied").build(); 
    } 
} 

边注：如Apache下议院IO库读取IO数据
