解析密碼保護的HTML

Question

我只想在登錄後從頁面中檢索源（字符串）。當我按登錄按鈕時，它給了我第一頁（登錄頁面）的來源。無論我輸入正確還是錯誤的密碼，結果都是一樣的。您的幫助將不勝感激。

' - （IBAction爲）buttonPressed：（ID）發送{

// PERFORM LOGIN 
url = [NSURL URLWithString:@"https://www.page asking username and password/"]; 
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
[request setRequestMethod:@"POST"]; 
[request setPostValue:userName.text forKey:@"UserID"]; 
[request setPostValue:password.text forKey:@"Password"]; 
[request setDelegate:self]; 

[request setDidFailSelector:@selector(PostFailed:)]; 
[request setDidFinishSelector:@selector(PostFinished:)]; 
[request startSynchronous]; 

}

- (void)PostFailed:(ASIHTTPRequest *)theRequest 
{ 
//notify user 
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Error sending request to the server" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
[alert show]; 


} 

- (void)PostFinished:(ASIHTTPRequest *)theRequest

//這裏得到你的帖子的響應數據...

url = [NSURL URLWithString:@"https://www.page after I loged in"]; 
ASIHTTPRequest *mainRequest = [ASIHTTPRequest requestWithURL:url]; 

[theRequest setDelegate:self]; 
[mainRequest startAsynchronous]; 


NSLog(@"Response %d ==> %@", theRequest.responseStatusCode, [theRequest responseString]); 

} `

您嘗試使用Cookies來驗證您的網站的可能性最大。 由於您正在進行原始HTTP請求，而不是以您的名義存儲cookie，所以您始終會被重定向到登錄頁面，因爲您始終保持未經身份驗證。

要訪問更多網站，您必須在代碼中實現cookie處理。
