用代码举例专家咨询(zhuanGPT):从前台传入文字,从前台传入专家领域,从后台返回“hello”,做出用户界面(XML文件),从用户界面输入的信息保存到字符串或将上传的文件保存到一个特定文件夹,并从后台(XML文件对应的java文件)返回字符串hello到用户界面

以下是一个简单的示例代码,涉及到前台页面、后台Java文件以及XML文件的交互:
前台页面(假设为HTML):
```
<!DOCTYPE html>
<html>
<head>
<title>专家咨询</title>
</head>
<body>
<form action="consultation.jsp" method="post">
<label for="text">请输入您的问题:</label><br>
<textarea id="text" name="text" rows="4" cols="50"></textarea><br>
<label for="field">请选择专家领域:</label><br>
<select id="field" name="field">
<option value="medicine">医学</option>
<option value="law">法律</option>
<option value="finance">金融</option>
</select><br>
<input type="submit" value="提交">
</form>
</body>
</html>
```
后台Java文件(假设为consultation.jsp):
```java
<%@ page import="java.io.*, java.util.*" %>
<%@ page import="javax.servlet.*, javax.servlet.http.*" %>
<%@ page import="org.apache.commons.fileupload.*" %>
<%@ page import="org.apache.commons.fileupload.disk.*" %>
<%@ page import="org.apache.commons.fileupload.servlet.*" %>
<%@ page import="org.apache.commons.io.output.*" %>
<%
// 从前台获取用户输入的问题和专家领域
String text = request.getParameter("text");
String field = request.getParameter("field");
// 执行专家咨询的代码,这里只返回一个简单的字符串“hello”
String result = "hello";
// 将结果返回给前台页面
response.setContentType("text/plain");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(result);
%>
```
XML文件(假设为consultation.xml):
```xml
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:fmt="http://java.sun.com/jsp/jstl/fmt"
version="2.0">
<jsp:directive.page contentType="text/html;charset=UTF-8" />
<jsp:output omit-xml-declaration="yes" />
<jsp:include page="consultation.jsp" />
</jsp:root>
```
用户界面(假设为Android的XML文件):
```xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/result_textview"
android:text="等待结果..."
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="@+id/submit_button"
android:text="提交"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
```
在Android的Java代码中,可以通过以下方式获取用户输入的问题和专家领域,并将其传递给后台Java文件:
```java
// 获取用户输入的问题和专家领域
String text = ((EditText) findViewById(R.id.text_edittext)).getText().toString();
String field = ((Spinner) findViewById(R.id.field_spinner)).getSelectedItem().toString();
// 将问题和领域上传到后台
String result = "";
try {
URL url = new URL("http://example.com/consultation.xml");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write("text=" + URLEncoder.encode(text, "UTF-8") + "&field=" + URLEncoder.encode(field, "UTF-8"));
writer.flush();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
result += line;
}
writer.close();
reader.close();
} catch (Exception e) {
e.printStackTrace();
}
// 将结果显示在用户界面上
((TextView) findViewById(R.id.result_textview)).setText(result);
```
