Question

我正在使用Spring框架与Tomcat 7＆amp; MySQL的。我使用UTF-8编码提交本地语言的表单数据。这通过JSP使用post工作正常。但是，在使用基于Ajax的表单提交时，它会将垃圾字符显示为服务器中的请求参数。

如果我遗失任何东西，请告诉我。

** My Ajax Code**

    xmlHttp.open("POST", "viewTeluguScript.htm", true);
    //xmlHttp.setRequestHeader("Content-type", "multipart/form-data;charset=UTF-8");
    xmlHttp.setRequestHeader("Content-length", parameters.length);
    // xmlHttp.setRequestHeader("Content-Type", "text/html;charset=UTF-8");
    xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded;charset=UTF-8");
    //xmlHttp.setRequestHeader("pageEncoding","UTF-8");
    //xmlHttp.setRequestHeader("accept-charset","UTF-8");
    xmlHttp.setRequestHeader("content-language","tel");
    xmlHttp.setRequestHeader("Connection", "close");
    xmlHttp.send(parameters);


    **My Controller code**

    public ModelAndView viewTeluguScript(HttpServletRequest request, HttpServletResponse response) throws SQLException, CannotGetJdbcConnectionException, Exception {

    //textInfo = java.net.URLDecoder.decode(request.getParameter("teluguText"), "UTF-8");
    textInfo = request.getParameter("teluguText");
    /* StringBuffer jb = new StringBuffer();
    String line = null;
    try {
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null)
    jb.append(line);
    } catch (Exception e) { 


    }

    System.out.println("request is :::: "+jb.toString());*/


    ModelAndView mv = new ModelAndView("viewQuestions");
    //request.getSession().setAttribute("workingModule", "questions");
    return mv;
    }

尝试添加内容编码的http标头您的浏览器使用Unicode来表示要显示的数据。来自Web服务器的资源可以选择在http头中附加编码信息。如果存在内容编码头，则浏览器使用响应头中的编码将资源转换为内部unicode表示。如果没有内容编码标头，则浏览器假定文件编码与请求资源的页面相同。
