从HttpServletRequest检索JSON对象文字 [英] Retrieving JSON Object Literal from HttpServletRequest

问题描述

我正在编写需要提取发布到servlet的对象文字的代码.我已经研究了HttpServletRequest对象的API，但是我不清楚如何从请求中获取JSON对象，因为它不是从网页上的表单元素发布的.

I am writing code that needs to extract an object literal posted to a servlet. I have studied the API for the HttpServletRequest object, but it is not clear to me how to get the JSON object out of the request since it is not posted from a form element on a web page.

任何见识都值得赞赏.

Any insight is appreciated.

谢谢.

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    StringBuilder sb = new StringBuilder();
    BufferedReader reader = request.getReader();
    try {
        String line;
        while ((line = reader.readLine()) != null) {
            sb.append(line).append('\n');
        }
    } finally {
        reader.close();
    }
    System.out.println(sb.toString());
}
