我的任务
分享如何使用java将数据post到一个servlet
我按照《java network programming》中的例子进行试验但是没有成功。
代码如下：
url = new URL("http://127.0.0.1:8080/Test/servlet/postServlet");
URLConnection uc = url.openConnection( );
uc.setDoOutput(true);
OutputStream raw = uc.getOutputStream( );
OutputStream buffered = new BufferedOutputStream(raw);
OutputStreamWriter out = new OutputStreamWriter(buffered, "8859_1");
out.write("first=Julie&middle=&last=Harting&work=String+Quartet\r\n");
out.flush( );
out.close( );
其中postServlet代码如下
protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1)
throws ServletException, IOException {
doPost(arg0,arg1);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.printl("success");
}
如果是读取一个URL的数据已经成功了，但是如何向一个Servlet post数据呢？
代码如下：
url = new URL("http://127.0.0.1:8080/Test/servlet/postServlet");
URLConnection uc = url.openConnection( );
uc.setDoOutput(true);
OutputStream raw = uc.getOutputStream( );
OutputStream buffered = new BufferedOutputStream(raw);
OutputStreamWriter out = new OutputStreamWriter(buffered, "8859_1");
out.write("first=Julie&middle=&last=Harting&work=String+Quartet\r\n");
out.flush( );
out.close( );
其中postServlet代码如下
protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1)
throws ServletException, IOException {
doPost(arg0,arg1);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String servletPath = "http://cxz/vml/s.jsp";
这一句可以是servlet路径,也可以是jsp路径,但要注意,不能是普通的html静态页面,否则出现回应错误如果是htm,应该去掉以下三句
PrintStream output = new PrintStream(reverseConn.getOutputStream());
output.print(reqstring);
output.flush();
向servlet发送的post参数长度无限制,我曾经设置过2M的长度,如果打算把servlet的输出存到一个文件,则调用第二个重载函数getOutText

URL默认是get操作，要改变URL请求操作类型必需通过HttpURLConnection 来实现。代码如下：
try {
StringBuffer strFileInfoBuf = new StringBuffer();
//发送文件数据信息:提交操作类型(FLAG)、传送的文件名称(name)
String strProcessURL =
"http://127.0.0.1/NSSB/MyServlet?FLAG=sendfile&name=apptest.log";
//connect server
URL objURL = new URL(strProcessURL);
HttpURLConnection objConn = (HttpURLConnection) objURL.openConnection();
//设置允许output
objConn.setDoOutput(true);
//设置为post方式
objConn.setRequestMethod("POST");
StringBuffer strTempBuf = new StringBuffer();
byte[] byteArray = new byte[2048];
int nReadCount = -1;
BufferedOutputStream objOutput =
new BufferedOutputStream(objConn.getOutputStream());
FileInputStream objFileIn = new FileInputStream("c:\\apptest.log");
while ((nReadCount = objFileIn.read(byteArray)) != -1) {
objOutput.write(byteArray, 0, nReadCount);
}
objOutput.flush();
objFileIn.close();
objOutput.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
StringBuffer strFileInfoBuf = new StringBuffer();
//发送文件数据信息:提交操作类型(FLAG)、传送的文件名称(name)
String strProcessURL =
"http://127.0.0.1/NSSB/MyServlet?FLAG=sendfile&name=apptest.log";
//connect server
URL objURL = new URL(strProcessURL);
HttpURLConnection objConn = (HttpURLConnection) objURL.openConnection();
//设置允许output
objConn.setDoOutput(true);
//设置为post方式
objConn.setRequestMethod("POST");
StringBuffer strTempBuf = new StringBuffer();
byte[] byteArray = new byte[2048];
int nReadCount = -1;
BufferedOutputStream objOutput =
new BufferedOutputStream(objConn.getOutputStream());
FileInputStream objFileIn = new FileInputStream("c:\\apptest.log");
while ((nReadCount = objFileIn.read(byteArray)) != -1) {
objOutput.write(byteArray, 0, nReadCount);
}
objOutput.flush();
objFileIn.close();
objOutput.close();
} catch (Exception e) {
e.printStackTrace();
}

通过url地址传送post参数是不切实际的,在我的类中只需要设置getOutText的第二个参数params,该参数是一个二维数组,比如request=query,format=xml,query=select * from substation where name like '%硖北%'的话,就如下设置
String params[][]={ {"request","query"}, {"format","xml"}, {"query","select * from substation where name like '%硖北%'"} };
String params[][]={ {"request","query"}, {"format","xml"}, {"query","select * from substation where name like '%硖北%'"} };

这个过段时间我也要试。
确实很多答非所问。
楼主是要在java代码里面post数据而不是通过页面提交。

“如果是读取一个URL的数据已经成功了，但是如何向一个Servlet post数据呢？”
你是否希望把你自己的参数通过url地址传送给Servlet？

我推荐使用URLConnection，它不需要设置method，可以把参数附加到url上，也可以通过OutputStream写到http body区

给你一个例子
Jsp的一个重要特性就是可以用javaBean实现功能的扩展。将大部分功能放在javaBean中完成，以使jsp页面程序更干净简洁、利于维护。JavaBean可以很方便的用来捕获页面表单的输入并完成各种业务逻辑的处理。如下就是一个Hello示例：
testA.jsp页面：
<%@ page contentType="text/html;charset=GBK" %>
<html>
<head>
<title>示例</title>
</head>
<body scroll=no>
<form name="frma" method="post" action="testB.jsp" >
<p>
你的姓名：
<input type="text" size="15" name="yourName" value="" id=yourName>
<input type="button" align="center" name="subBtn" value="[提交]" onClick="f_check()" id=subBtn>
</p>
</form>
</body>
</html>
<script language="JavaScript" type="text/javascript">
<!--
function f_check(){
if(document.forms(0).yourName.value==""){
alert("请输入姓名");
}else{
document.forms(0).submit();
}
}
-->
</SCRIPT>
testB.jsp页面
<%@ page contentType="text/html;charset=GBK" %>
<html>
<head>
<title>示例</title>
</head>
<jsp:useBean id="tBean" scope="page" class="bean.TestBean" >
<jsp:setProperty name="tBean" property="*" />
</jsp:useBean>
<body scroll=no>
<form name="frmb" method="post" action="" >
<p>
<%=tBean.hello()%>
</p>
</form>
</body>
</html>
TestBean.java 代码：
package bean;
public class TestBean{
private String yourName = "";
public void setYourName(String yourName){
this.yourName = ConvertGBK(yourName);
}
public String hello(){
String strHello = "Hello:"+yourName;
return strHello;
}
//汉字转换方法
public String ConvertGBK(String str){
String strReturn="";
try{
strReturn=new String(str.getBytes("ISO-8859-1"),"GBK");
}catch(Exception ex){
System.out.println("TestBean.ConvertGBK():ex="+ex.toString());
}
finally{
return strReturn;
}
}
}
testA.jsp页面上“提交”按钮将表单提交给testB.jsp页面，testB.jsp获得的testA.jsp中yourName文本框的值并在实例化TestBean后，执行bean中的setYourName方法，接着执行hello方法，在页面上输出对你问好的语句。
这个简单的示例体现了在jsp中使用javaBean的两个重要方面，一个是捕获表单的输入并保存，一个是执行逻辑功能。所以，依此两个功能还可以将用在jsp中的javaBean分为值Bean(value bean)和工具Bean (utility bean)，如下：
值Bean
package bean;
public class TestValueBean{
private String yourName = "";
public void setYourName(String yourName){
this.yourName = ConvertGBK(yourName);
}
//汉字转换方法
public String ConvertGBK(String str){
String strReturn="";
try{
strReturn=new String(str.getBytes("ISO-8859-1"),"GBK");
}catch(Exception ex){
System.out.println("TestBean.ConvertGBK():ex="+ex.toString());
}
finally{
return strReturn;
}
}
}
工具Bean
package bean;
public class TestUtilityBean{
public String hello(TestValueBean tvBean){
String strHello = "Hello:"+tvBean.getName();
return strHello;
}
public String hello(String yourName){
String strHello = "Hello:"+yourName;
return strHello;
}
}
当然，从这个例子看是没有必要分开value bean和utility bean的，但在具有复杂业务逻辑的web应用程序中就可以用value bean实现对表单输入的捕获、保存，减少对数据库中那些值几乎不变的实体的访问，或将value bean放在一定作用域内使此作用域内的多个jsp页面共享。用utility bean完成操作数据库、数据处理等业务逻辑，以value bean 或页面传递的值为参数。
