Convert cookie string to a Cookie object in C# or Java - authentication

Question

I need to automatically access a website that requires authentication. I found cookie string of this website's http host (using fiddler). Is there a way to convert this string to a cookie object and pass it to a Webclient to pass the authentication?

Answer 1

Convert the Sting to a cookie object. For this you need to parse the String to get name, value, path, domain, etc.
You have to do something like this -
String[] cArray = cookieValueIs.split(";");
for (String s : cArray) {
s = s.trim();
int i1 = s.indexOf('=');
if (i1 != -1) {
String k = s.substring(0, i1).trim();
String v = s.substring(i1 + 1).trim();
if (k.equalsIgnoreCase(VERSION)) {
version = v;
} else if (k.equalsIgnoreCase(COMMENT)) {
comment = v;
} else if (k.equalsIgnoreCase(DOMAIN)) {
domain = v;
} else if (k.equalsIgnoreCase(PATH)) {
path = v;
} else if (k.equalsIgnoreCase(MAX_AGE)) {
maxAge = v;
} else if(k.equalsIgnoreCase(EXPIRES)){
continue;
}
else {
key = k;
value = v;
}
} else {
if (s.equalsIgnoreCase(SECURE)) {
secure = true;
} else if (s.equalsIgnoreCase(HTTPONLY)) {
httpOnly = true;
}
}
Once you are done with this create a cookie object-
Cookie cookie = new Cookie(key,value);
if(comment != null){
cookie.setComment(comment);
}
if(domain != null){
cookie.setDomain(domain);
}
if(path != null){
cookie.setPath(path);
}
if(version != null){
cookie.setVersion(Integer.parseInt(version));
}
if(secure){
cookie.setSecure(true);
Now your string is converted to the Cookie object --> cookie

This worked for me in c#.
public static Cookie ToCookie(this string #this)
{
String[] array = #this.Split(';');
var cookie = new Cookie();
foreach (var ss in array)
{
string key;
object value;
var s = ss.Trim();
int indexOf = s.IndexOf('=');
if (indexOf != -1) {
key = s.Substring(0, indexOf).Trim();
value = s.Substring(indexOf + 1).Trim();
} else
{
key = s.ToTitleCase();
value = true;
}
var prop = cookie.GetType().GetProperty(key.ToTitleCase());
if (prop != null)
{
var converted = Convert.ChangeType(value, prop.PropertyType);
prop.SetValue(cookie, converted, null);
}else
{
cookie.Name = key;
cookie.Value = value.ToString();
}
}
return cookie;
}
