以下代码是我到目前为止所尝试的：
try{
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet("http://somewebsite.com");
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
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://www.somewebsite.com/MemberSingIn");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("email", "USERNAME"));
nvps.add(new BasicNameValuePair("password", "PASSWORD"));
nvps.add(new BasicNameValuePair("rememberMe", "true"));
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
response = httpclient.execute(httpost);
entity = response.getEntity();
System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
entity.consumeContent();
}
System.out.println("Post logon cookies:");
cookies = httpclient.getCookieStore().getCookies();
String mySessionId = null;
if (cookies.isEmpty()) {
System.out.println("None");
} else {
for (int i = 0; i < cookies.size(); i++) {
if(cookies.get(i).toString().contains("SessionId=")){
int index1 = cookies.get(i).toString().indexOf("SessionId");
String temp = cookies.get(i).toString().substring(index1);
int index2 = temp.toString().indexOf("]");
temp = cookies.get(i).toString().substring(index1+10,index1+index2);
mySessionId = temp;
}
System.out.println("- " + cookies.get(i).toString());
}
}
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("Cookie",mySessionId);
cookieStore.addCookie(cookie);
httpclient.setCookieStore(cookieStore);
httpget = new HttpGet("http://somewebsite.URLTOGETFILE/eTable.txt");
response = httpclient.execute(httpget);
entity = response.getEntity();
System.out.println("HEREEEEEEEEEEEEEEEEEEE");
System.out.println(response.toString());
System.out.println("File get: " + response.getStatusLine());
InputStream in = entity.getContent();
File path = new File("/home/mrsevensevenseven/");
path.mkdirs();
File file = new File(path, "myfile.txt");
FileOutputStream fos = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
fos.write(buffer, 0, len1);
}
fos.close();
httpclient.getConnectionManager().shutdown();
}catch(Exception e){
e.printStackTrace();
}
它成功，登录但我仍然无法下载文件...在这方面的任何帮助将不胜感激..我已经尝试了很多堆栈溢出和谷歌搜索但无法得到帮助。
这就是回应......
