用java写的需要认证的网站上提交信息

Question

代码入下:
         /**
 * 提交信息
 * 
 * @param s
 *            服务器
 * @param param
 *            提交的数据
 * @throws Exception
 */
private void submit(Server s, Map param) throws Exception {

HttpURLConnection conn = (HttpURLConnection) new URL("http://" + s.ip
+ ":" + s.port).openConnection();
String authentication = (new sun.misc.BASE64Encoder())
.encode((s.adminName + ":" + s.adminPassword).getBytes());
conn.setRequestProperty("Authorization", "Basic " + authentication);
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK)
throw new Exception("连接失败!");

 conn = (HttpURLConnection) new URL("http", s.ip,
Integer.parseInt(s.port), "/account").openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization", "Basic " + authentication); Iterator it = param.keySet().iterator();
String p = "";
while (it.hasNext()) {
String key = (String) it.next();
p += key + "=" + param.get(key);
if (it.hasNext())
p += "&";
}
OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
out.write(p);
out.write("\r\n");
out.flush();
out.close(); BufferedReader br = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
出现的错误:
java.io.IOException: Server returned HTTP response code: 401 for URL: http://127.0.0.1:88/account
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1149)
at tool.proxy.UserManage.submit(UserManage.java:177)

System.out.println(br.readLine());
}

开两个贴,总共是110分.

Answer 2

我监听了n多天网络,还是没搞定顺便说一下,认证是basic

Answer 3

重新说明一下,我想用java的http连接做 basic认证 + Post数据,该怎么做?谁做这片比较多,我找了N家论坛没人解决！

Answer 4

...;conn.disconnect();
conn = (HttpURLConnection) new URL("http", s.ip, Integer.parseInt(s.port), "/account").openConnection();...;BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sbInfo = new StringBuffer();
if(br.ready()){
    String newLine = "\r\n";
    String readInfo = null;
    while((readInfo=br.readLine())!=null) {
        sbInfo.append(readInfo);
        sbInfo.append(newLine);
    }
}
System.out.println("Response message: \r\n" + sbInfo.toString());

Answer 5

嗯,这样在 没basic认证 上是可以的.谢谢楼上的回复和朋友的支持.

Answer 6

没有啊,只认证一次,下面是认证部分代码:String authentication = (new sun.misc.BASE64Encoder()).encode((s.adminName + ":" + s.adminPassword).getBytes());
conn.setRequestProperty("Authorization", "Basic " + authentication);

Answer 7

...;
conn.setRequestProperty("Authorization", "Basic " + authentication); // 1
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK)
throw new Exception("连接失败!");...;
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization", "Basic " + authentication);// 2

谢谢yaray(雅睿,生活在别处) 的回复.嗯,可能贴错了,但是去掉也不行.现在程序已经改成这样了,参数都是用嗅探器拦截IE上的,这样也试过,也是一样报.

Answer 10

想用socket直接发,参照嗅探IE的结果来发.

Answer 11

http://user2:88/account这个地址用普通的数据提交方式时是否可以正常工作?

Answer 12

谢谢yaray(雅睿,生活在别处) 的提示,终于搞定了,哈哈.......结贴,还有20分,麻烦去回一下贴.

Answer 13

可以的,用IE可以.20分的贴在这边.

Answer 14

错误错在,delete是一个submit按钮,我是在servlet取出为-1的,实际上Http监听上为delete=%C9%BE%B3%FD,URLDecoder.decode("%C9%BE%B3%FD", "UTF-8")为???,太粗心了,监听好几次都没仔细看.最终代码(socket直接发),测试通过:import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.URLEncoder;public class Test { public static void main(String args[]) {
try {
String data = "userid=0&autodisable=1&delete=%C9%BE%B3%FD&username=12&password=1212&enable=1&connection=10&bandwidth=-1&disabledate=2006-03-07&disabletime=21%3A46%3A38"; String authentication = (new sun.misc.BASE64Encoder())
.encode(("admin" + ":" + "").getBytes()); // Create a socket to the host
String hostname = "user2";
int port = 88;
InetAddress addr = InetAddress.getByName(hostname);
Socket socket = new Socket(addr, port); // Send header
String path = "/account";
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream(), "UTF8"));
wr.write("POST " + path + " HTTP/1.1\r\n");
wr.write("Content-Length: " + data.length() + "\r\n");
wr.write("Authorization: Basic " + authentication + "\r\n");
wr.write("Content-Type: application/x-www-form-urlencoded\r\n");
wr.write("\r\n"); // Send data
wr.write(data);
wr.flush();
wr.close();
socket.close();
} catch (Exception e) {
e.printStackTrace();
}
}
