急需Wireshark抓包软件的Java API

wireshark是基于winpcap或者libpcap的应用软件。如果你想自己开发抓包类的，应该用winpcap的api之类的。winpcap网站上faq提到这个问题了

五指山ssl适用于网站、小程序/APP、API接口等需要进行数据传输应用场景，ssl证书未来市场广阔！成为创新互联公司的ssl证书销售渠道，可以享受市场价格4-6折优惠！如果有意向欢迎电话联系或者加微信：028-86922220（备注：SSL证书合作）期待与您的合作！

Q-12: Does WinPcap work with Java?

A: We do not directly support Java. However you can find a Java wrapper at netresearch.ics.uci.edu/kfujii/jpcap/doc/index.html 和 jnetpcap.com /.

java 抓取网站下的所有网页。代码

贴的代码格式全乱了，我传了个附件。

里面的网址匹配还不完美，可以改进。

欢迎探讨。

如何可以用java实现后台抓包，然后提取想要的包

jPCAP在JAVA中，并非一个真正去实现对数据链路层的控制，而是一个中间件，JPCAP调用winpcap/libpcap，给JAVA语言提供一个公共的接口，从而实现了平台无关性。

如何通过抓包工具fiddler获取java程序的http请求

firefox的fidder插件 Java程序需要设置proxy才能生效：

String url="url address";

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("127.0.0.1", 8888));

URL serverUrl = new URL(url);

HttpURLConnection conn = (HttpURLConnection) serverUrl.openConnection(proxy);

以下是完整参考代码：

package com.http;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.InetSocketAddress;

import java.net.Proxy;

import java.net.URL;

public class Http302Redirect {

public static void main(String[] args) {

try {

String url = "http 你的地址";

System.out.println("访问地址:" + url);

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,

new InetSocketAddress("127.0.0.1", 8888));

URL serverUrl = new URL(url);

HttpURLConnection conn = (HttpURLConnection) serverUrl

.openConnection(proxy);

conn.setRequestMethod("GET");

conn.addRequestProperty("Accept-Charset", "UTF-8;");

conn.addRequestProperty("User-Agent",

"Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.8) Firefox/3.6.8");

conn.addRequestProperty("Referer", "");

conn.connect();

BufferedReader reader = new BufferedReader(new InputStreamReader(

conn.getInputStream()));

StringBuffer buffer = new StringBuffer();

String line = reader.readLine();

while (line != null) {

buffer.append(line).append("\r\n");

line = reader.readLine();

}

reader.close();

conn.disconnect();

System.out.println(buffer);

} catch (Exception e) {

e.printStackTrace();

}

}

}

response.reset();

response.setContentType("application/x-msdownload");

response.setContentLength((int)filelength);

response.addHeader("Content-Disposition","attachment; filename=\"" + toUtf8String(filename) + "\"");

//循环取出流中的数据

byte[] b = new byte[100];

int len;

response.getOutputStream().write(b,0,len);

上面的那个是用流写的 但是也可以用超链接下载

你写上文件的路径就可以了
