我試圖打一個URL（登錄屏幕），獲取jsessionid（J2EEJSESSIONID）並將其添加到cookie存儲中，然後轉到上下文並使用憑據訪問相同的URL。我期待登錄成功的屏幕。 但是我再次登錄屏幕反彈。 而且，我打印了兩個匹配的響應頭。我期待着同一個J2EESESSIONID的響應來維持會話。相反，兩個會話ID都是不同的。請幫助。爲什麼httpclient爲每個請求刷新jsession id？
請找到下面的代碼：
HttpEntity entity = null;
DefaultHttpClient httpClient = new DefaultHttpClient();
try{
// Initialization
HttpPost httpPost = new HttpPost("https://yyyyy.xxx.com/enl");
HttpClientExample httpClientExample = new HttpClientExample();
CookieStore cookieStore = new BasicCookieStore();
HttpContext httpContext = new BasicHttpContext();
httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
HttpGet httpGet = new HttpGet("https://yyyyy.xxx.com/enl");
// Execute Get
HttpResponse httpResponse = httpClient.execute(httpGet, httpContext);
// Print the header for 1st url
org.apache.http.Header[] headers = httpResponse.getAllHeaders();
System.out.println("##### Header length::"+headers.length);
for(int i=0;i<headers.length; i++)
{
System.out.println("Header Name::"+headers[i].getName());
System.out.println("Header Val::"+headers[i].getValue());
}
// update Cookie for the next hit
org.apache.http.Header[] cookieHeaders = httpResponse.getHeaders("Set-Cookie");
String html = EntityUtils.toString(httpResponse.getEntity());
cookieStore = httpClientExample.updateCookieStore(cookieHeaders, cookieStore);
httpClient.setCookieStore(cookieStore);
httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
// Setting the redirects since i received 302 error
httpClient.setRedirectStrategy(new DefaultRedirectStrategy() {
public boolean isRedirected(HttpRequest request, HttpResponse response, HttpContext context) {
boolean isRedirect=false;
try {
isRedirect = super.isRedirected(request, response, context);
} catch (ProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (!isRedirect) {
int responseCode = response.getStatusLine().getStatusCode();
if (responseCode == 301 || responseCode == 302) {
return true;
}
}
return false;
}
});
// Added because i received Circular redirect error
httpClient.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
// Execute Post with credentials
httpClient.getCredentialsProvider().setCredentials(
new AuthScope("http://yyyyy.xxx.com", 443),
new UsernamePasswordCredentials("usr", "pswd"));
httpPost.setHeader("Cookie", "JSESSIONID="+ getSessionId(cookieHeaders));
HttpResponse response = httpClient.execute(httpPost, httpContext);
// Print the response
entity = response.getEntity();
InputStream content1 = (InputStream)entity.getContent();
System.out.println("############### 2nd #####################"+response.getStatusLine().getStatusCode());
BufferedReader in1 =
new BufferedReader (new InputStreamReader (content1));
String line1;
while ((line1 = in1.readLine()) != null) {
System.out.println(line1);
}
// Print the header for 2nd url
org.apache.http.Header[] headers1 = response.getAllHeaders();
System.out.println("##### Header length 2 ::"+headers1.length);
for(int i=0;i<headers1.length; i++)
{
System.out.println("Header Name 2 ::"+headers1[i].getName());
System.out.println("Header Val 2 ::"+headers1[i].getValue());
}
}
catch(Exception e)
{
e.printStackTrace();
}
finally{
try {
EntityUtils.consume(entity);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
httpClient.getConnectionManager().shutdown();
}
}
private static String getSessionId(org.apache.http.Header[] headers) {
// TODO Auto-generated method stub
for(int i=0;i<headers.length; i++)
{
String str = headers[i].getValue();
String[] strArray = str.split("=");
String[] cookieValueArray = strArray[1].split(";");
System.out.println(strArray[0]+"|"+cookieValueArray[0]);
if(strArray[0].startsWith("J2EEJSESSION"))
{
System.out.println("cookieValueArray[0]:"+cookieValueArray[0]);
return cookieValueArray[0];
}
}
return null;
}
protected CookieStore updateCookieStore(org.apache.http.Header[] headers, CookieStore cookieStore)
{
for(int i=0;i<headers.length; i++)
{
String str = headers[i].getValue();
String[] strArray = str.split("=");
String[] cookieValueArray = strArray[1].split(";");
System.out.println(strArray[0]+"|"+cookieValueArray[0]);
BasicClientCookie cookie = new BasicClientCookie(strArray[0], "A"+cookieValueArray[0]);
/*if(strArray[0].startsWith("J2EEJSESSION"))
{
cookie.setDomain("yyyyy.xxx.com");
}
else
{
cookie.setDomain(".xxx.com");
}*/
cookie.setDomain(".xxx.com");
cookie.setPath("/");
cookieStore.addCookie(cookie);
if(strArray[0].startsWith("J2EEJSESSION"))
{
BasicClientCookie cookie1 = new BasicClientCookie("JSESSIONID", "A"+cookieValueArray[0]);
cookie1.setDomain(".xxx.com");
cookie1.setPath("/");
cookieStore.addCookie(cookie1);
}
}
return cookieStore;
}
另一種看法： 當我從下面的代碼片段刪除「A」 CONCAT，我沒有得到J2EESESSIONID在第二擊：
BasicClientCookie cookie = new BasicClientCookie（strArray [0]，「A」+ cookieValueArray [0]）;
