自动登录+Nginx反向代理
一、获取登录cookie
1.编写HTTP访问
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;
import java.util.HashMap;
import java.util.Map;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
public class HttpUtils {
public Map<String,Object> executeHttps(String urlStr,String param,String requestMethod,Map<String,String> requestProperty,Boolean isRedirect) throws Exception {
Map<String,Object> map=new HashMap<String, Object>();
DataOutputStream out=null;
InputStreamReader input=null;
BufferedReader brd=null;
HttpsURLConnection connet=null;
try {
// 实例一个URL资源
URL url = new URL(urlStr);
// 实例一个HTTP CONNECT
connet = (HttpsURLConnection) url.openConnection();
connet.setDoInput(true);
connet.setDoOutput(true);//如果通过post提交数据，必须设置允许对外输出数据
connet.setUseCaches(false);//请求不能使用缓存
connet.setInstanceFollowRedirects(isRedirect); //不允重定向
connet.setRequestMethod(requestMethod);
for(Map.Entry<String,String> mapEntry:requestProperty.entrySet()){
connet.setRequestProperty(mapEntry.getKey(), mapEntry.getValue());
}
connet.setConnectTimeout(1000*15);// 连接超时 单位毫秒
connet.setReadTimeout(1000*60*20);// 读取超时 单位毫秒
connet.connect();
if(param!=null){
out = new DataOutputStream(connet.getOutputStream());
out.writeBytes(param); //写入请求的字符串
out.flush();
}
if (connet.getResponseCode() != 200) {
new Throwable("请求异常:" + urlStr);
}
InputStream inputStream = connet.getInputStream();
// 将返回的值存入到String中
input = new InputStreamReader(inputStream);
brd = new BufferedReader(new InputStreamReader(connet.getInputStream(), "utf-8"));
StringBuilder sb = new StringBuilder();
String line;
while ((line = brd.readLine()) != null) {
sb.append(line);
}
map.put("header", connet.getHeaderFields());
map.put("body", sb.toString());
} catch (Exception e) {
e.printStackTrace();
throw e;
}finally{
if(out!=null){
out.close();
}
if(input!=null){
input.close();
}
if(brd!=null){
brd.close();
}
if(connet!=null){
connet.disconnect();
}
}
return map;
}
/**
* ===============跳过HTTPS证书================
*/
static {
try {
trustAllHttpsCertificates();
HttpsURLConnection.setDefaultHostnameVerifier((urlHostName, session) -> true);
} catch (Exception e) {
}
}
private static void trustAllHttpsCertificates() throws NoSuchAlgorithmException, KeyManagementException {
TrustManager[] trustAllCerts = new TrustManager[1];
trustAllCerts[0] = new TrustAllManager();
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, null);
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
}
private static class TrustAllManager implements X509TrustManager {
public X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkServerTrusted(X509Certificate[] certs,String authType) {
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
}
}2.编写登录获取cookie方法
public Map<String,String> veeamLogin() throws Exception{
HttpUtils hu=new HttpUtils();
Map<String,String> proxyRequestCookieMap=new HashMap<String, String>();
try {
String pwd=encoder.encodeToString(pwdStr.getBytes());
Map<String,String> hm=new HashMap<String,String>();
hm.put("Accept","*/*");
hm.put("Accept-Encoding","gzip, deflate, br");
hm.put("Accept-Language","zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2");
hm.put("Connection","keep-alive");
//hm.put("Content-Length","38");
hm.put("Content-Type","application/x-www-form-urlencoded; charset=UTF-8");
hm.put("Host","XXXXXX");
hm.put("Origin","https://XXXXXX");
hm.put("Referer","https://XXXXXX/login.aspx");
hm.put("TE","Trailers");
hm.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:77.0) Gecko/20100101 Firefox/77.0");
hm.put("X-Requested-With","XMLHttpRequest");
StringBuffer p=new StringBuffer();
p.append("password="+pwd+"&username="+nameStr);
Map<String, Object> executeHttps = hu.executeHttps(urlStr,p.toString(), "POST", hm,false);
@SuppressWarnings("unchecked")
Map<String,List<String>> hmap=(Map<String, List<String>>) executeHttps.get("header");
for(Map.Entry<String, List<String>> ml:hmap.entrySet()){
if("Set-Cookie".equals(ml.getKey())){
for(String mlv:ml.getValue()){
String[] hTempValueArr=mlv.toString().split(",");
for(String htva:hTempValueArr){
String[] htvaArr=htva.split(";");
for(String htvaa:htvaArr){
if(htvaa.indexOf("=")>-1){
String[] htvaaArr=htvaa.split("=");
proxyRequestCookieMap.put(htvaaArr[0], htvaaArr[1]);
}
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
throw e;
}
return proxyRequestCookieMap;
}注：pwdStr，nameStr，urlStr为访问网站的URL，用户名，密码
3.编写JSP用来给浏览器写cookie,写完后访问目标网站
<%
AutoLogin al=new AutoLogin();
Map<String,String> map=al.veeamLogin();
Cookie servletCookie = new Cookie(".aaaa",map.get(".aaaa"));
servletCookie.setPath("/");
servletCookie.setVersion(1);
response.addCookie(servletCookie);
servletCookie = new Cookie(".bbbbb",map.get(".bbbbb"));
servletCookie.setPath("/");
servletCookie.setVersion(1);
response.addCookie(servletCookie);
response.sendRedirect("http://10.180.26.101/index.aspx");
%>二、nginx配置
1.nginx配置（访问步骤使用jsp访问一次把cookie写到浏览器，然后jsp访问目标页面这样就不用登录直接访问了）
worker_processes 1;
events {
worker_connections 1024;
accept_mutex on; #设置网路连接序列化，防止惊群现象发生，默认为on
multi_accept on; #设置一个进程是否同时接受多个网络连接，默认为off
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name 10.180.26.101;
location / {
proxy_pass https://xxxxxxxx:9443;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cookie_path / /;
proxy_set_header Cookie $http_cookie;
#ws wss访问
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Origin "";
}
#jsp自动登录
location ~ \.(jsp|jspx|do|wsdl)?$ {
proxy_pass http://10.180.26.101:8080;
#ws wss访问
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cookie_path / /;
proxy_set_header Cookie $http_cookie;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Origin "";
}
}
}注:由于目标页面有ws wss访问需要配置如下代码：
#ws wss访问
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Origin "";赞(1)
