我已经做了这个代码
DefaultHttpClient httpclient = new DefaultHttpClient();
CookieStore cookieStore = new BasicCookieStore();
HttpContext httpContext = new BasicHttpContext();
httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
HttpGet httpget = new HttpGet("http://localhost:8080/Account/Login");
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
InputStream is = entity.getContent();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String str ="";
while ((str = br.readLine()) != null){
System.out.println(""+str);
}
entity.consumeContent();
}
System.out.println("Initial set of cookies:");
List<Cookie> cookies = httpclient.getCookieStore().getCookies();
if (cookies.isEmpty()) {
System.out.println("None");
} else {
for (int i = 0; i < cookies.size(); i++) {
System.out.println("- " + cookies.get(i).toString());
}
}
HttpPost httpost = new HttpPost("http://localhost:8080/Account/Login");
List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("Username", "e"));
nvps.add(new BasicNameValuePair("Password", "password"));
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
response = httpclient.execute(httpost);
entity = response.getEntity();
System.out.println("Double check we've got right page " + EntityUtils.toString(entity));
System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
entity.consumeContent();
}
System.out.println("Post logon cookies:");
cookies = httpclient.getCookieStore().getCookies();
if (cookies.isEmpty()) {
System.out.println("None");
} else {
for (int i = 0; i < cookies.size(); i++) {
System.out.println("2nd- " + cookies.get(i).toString());
}
}
这已经对了吗？？以及如何访问另一个网址？？？让我们说从登录页面之后，我想去 localhost:80/test 页面。帮我解决这个问题。我是这个http客户端的新手。
