如何在doPost()调用上设置UTF-8响应? [英] How to Set UTF-8 response on doPost() call?
问题描述
我试图用UTF-8数据返回到页面的JSON响应，因为这是我从Form发布到我的osgi servlet的内容. Servlet代码如下所示:
I Am trying to have a JSON response back to the page with UTF-8 data, as it is what i have posted from the Form to my osgi servlet. The Servlet code is as shown below:
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
@SlingServlet(paths="/bin/JsonOsgiCall", methods = "POST", metatype=true)
public class JsonOsgiCall extends org.apache.sling.api.servlets.SlingAllMethodsServlet {
private static final long serialVersionUID = 2598426539166788515L;
protected final Logger log = LoggerFactory.getLogger(this.getClass());
@Override
protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServerException, IOException {
response.setContentType("text/html; charset=UTF-8");
response.setCharacterEncoding("UTF-8");
request.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
JSONObject jsonobj = new JSONObject();
try {
jsonobj.put("testint", 30);
jsonobj.put("myjspstring", request.getParameter("userinmsg"));
jsonobj.put("myjspstati","`İş hayatında ne çok engelle karşılaşıldığını,`");
JSONArray list = new JSONArray();
list.add("message 1");
list.add("message 2");
jsonobj.put("messages", list);
log.info("*** JSON Object with ***" + jsonobj.toJSONString());
//out.println(jsonobj.toJSONString());
out.println(jsonobj);
}
catch (Exception e) {
e.printStackTrace();
}
}
}
我的JSP表单代码如下所示:
And my JSP Form code shown as below:
<%@include file="/libs/foundation/global.jsp"%><%
%><%@page session="false" %>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="org.json.simple.JSONObject,java.io.PrintWriter,java.util.*"%>
<%
%>CALL OSGI SERVICE FOR JSON RESPONSE
<cq:includeClientLib js="granite.csrf.standalone"/>
<head>
<meta charset="UTF-8" />
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<title>Editer les sous-titres</title>
</head>
<body>
<form id="submitForm" method="POST" action="/bin/JsonOsgiCall">
<textarea name="userinmsg" autocomplete="off" type="text" id="userinmsg" rows="4" cols="30" style="width: 450px; margin-left: 25px;">
</textarea>
<br/>
<p style="margin-left: 420px;"><input name="submitmsg" type="submit" id="submitmsg" value="Call JSON Service" /></p>
</form>
</body>
但是当我提交表单并看到返回到页面的输出时，就像ANSI格式一样.我在以下位置添加的JSON数据:
But when I submit the Form and see the output that has resulted back to the page is like with ANSI format. Where the the JSON data that I have added in the:
jsonobj.put("myjspstati","İş hayatında ne çok engelle karşılaşıldığını,");
在这两个代码段之间可以很好地返回页面.但是，当表单通过以下方式接收到servlet时，提交的表单的相同代码在哪里中断了:
In between code snippet is coming fine back to page. But where as the form submitted same code is breaking when it received into servlet with:
request.getParameter(userinmsg)
如何获取启用了UTF的数据，这些数据可以正确发送到Servlet，并可以使用它完成JSON对象.
How can I get the UTF enabled data that can be properly sent to Servlet and can do the JSON object with same.
在我的浏览器开发人员工具中进行调试 请求标题

推荐答案
您可以看到您的字符集已损坏(，因为使用utf-8的ServerSide json数据正确无误，并且您对请求有疑问.提交表单后传输getParameter()).
you can see your charset is being broken(as the ServerSide json data with utf-8 is resulted correct and you have a doubt in your request.getParameter()) when it is getting transferred after form submission.
尝试添加<input type="hidden" name="_charset_" value="UTF-8"/>，浏览器将在其中填写提交的字符编码作为该字段的值.
Try adding <input type="hidden" name="_charset_" value="UTF-8"/> where browser will fill-in the submitted character encoding as the field's value.
单独修改了表单以及字符集utf-8的隐藏输入
<form id="submitForm" method="POST" action="/bin/JsonOsgiCall">
<textarea name="userinmsg" autocomplete="off" type="text" id="userinmsg" rows="4" cols="30" style="width: 450px; margin-left: 25px;">
</textarea>
<br/>
<input type="hidden" name="_charset_" value="UTF-8"/>
<p style="margin-left: 420px;"><input name="submitmsg" type="submit" id="submitmsg" value="Call JSON Service" /></p>
</form>
在AEM级别Felix Config上处理它的另一种方法
在Apache Sling Request Parameter Handling Default Parameter Encoding中将您的字符集设置为UTF-8，如下图所示.
Set your charset to UTF-8 in Apache Sling Request Parameter Handling Default Parameter Encoding as shown below screenshot.
