Servlet 参数和 doPut [英] Servlet parameters and doPut

问题描述

尝试使用 HttpServlet#doPut 从 PUT 请求中获取参数:

Trying to get parameters from a PUT request using HttpServlet#doPut:

public void doPut(HttpServletRequest request, HttpServletResponse response) {
    String name = request.getParameter("name");
    // name is null
}

使用 curl 发送请求:

Using curl to send the request:

curl  -X PUT 
      --data "name=batman" 
      --header "Content-Type: text/plain" http://localhost:8080/sample.html

使用 doGet 和 GET curl 请求可以正常工作.我错过了什么吗?

works fine with using doGet and GET curl request. Am I missing something?

推荐答案

根据评论和进一步的研究，我意识到 Servlet 不能假设任何关于放入服务器的数据，因此不会解析名称/值对.

Based on comments and further research I realized that the Servlet cannot assume anything about the data being put onto the server and therefore, will not parse name/value pairs.

以下解决方案似乎是处理通过 PUT 传递的任何数据的正确方法，并且可以解析为 XML、名称/值或其他任何内容.

The following solution seems to be the proper way to handle any data passed via PUT, and can be parsed as XML, Name/Value, or whatever.

BufferedReader br = new BufferedReader(new InputStreamReader(req.getInputStream());

String data = br.readLine();
