我有一个带有Spring Security Framework的Web应用程序并在Tomcat 8上运行。现在,我面临一个新问题,即创建支持没有cookie的用户会话的Android应用程序。我试图找到一些文档like this,我尝试使用HttpUrlConnection
(我不知道哪一个更好用其他文件),这是我的失败代码。
public static String jsessionid = SessionIdentifierGenerator.nextSessionId();
public static String performPostCall(String requestURL,
HashMap<String, String> postDataParams) {
Log.d("url = ",requestURL);
URL url;
String response = "";
try {
url = new URL(requestURL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(45000);
conn.setConnectTimeout(45000);
conn.setRequestMethod("POST");
Log.d("Cookie : ", jsessionid);
conn.setRequestProperty("Cookie","JSESSIONID=" + SessionIdentifierGenerator.nextSessionId());
conn.setDoInput(true);
conn.setDoOutput(true);
// conn.connect();
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(postDataParams));
writer.flush();
int responseCode=conn.getResponseCode();
writer.close();
os.close();
System.out.println(".toString() = "+responseCode);
System.out.println(".HttpsURLConnection.HTTP_OK = "+HttpsURLConnection.HTTP_OK);
if (responseCode == HttpsURLConnection.HTTP_OK) {
String line;
BufferedReader br=new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line=br.readLine()) != null) {
response+=line;
}
}
else {
response="";
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
private static String getPostDataString(HashMap<String, String> params) throws UnsupportedEncodingException{
StringBuilder result = new StringBuilder();
boolean first = true;
for(Map.Entry<String, String> entry : params.entrySet()){
Log.d("entry.getKey() = ",entry.getKey());
Log.d("entry.getValue() = ",entry.getValue());
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
}
System.out.println("tetstes = "+result.toString());
return result.toString();
}
这个用于创建新会话的方法。
public final class SessionIdentifierGenerator {
private static SecureRandom random = new SecureRandom();
public static String nextSessionId() {
return new BigInteger(130, random).toString(32);
}
}
HashMap<String, String> parameter = new HashMap<String, String>();
parameter.put("username", username);
parameter.put("password", password);
最后我称之为performPostCall("http://localhost:8080/login/authenticate?spring-security-redirect=/login/ajaxSuccess", parameter);
