我正在編寫一個iPhone應用程序與運行Joomla(準確地說是JomSocial)的網站連接,並從中檢索某些信息。 我完全被困在最後的日子裏,就是認證過程。 我不是一個web/php專家(只知道基礎知識),並且首次與Joomla平臺結合開發。iPhone應用程序需要使用ASIHTTPRequest與Joomla進行身份驗證

這種情況是:有一個用戶登錄的登錄表單(用戶名/密碼/記住)的網站。 在iPhone上,用戶啓動應用程序,並顯示一個典型的登錄視圖,其中包含兩個UITextFields,一個用於用戶名,一個用於密碼。還有一個按鈕可以繼續進行身份驗證並調用下面的方法。 當用戶填寫必填字段時,應用程序會假定記住按鈕並繼續進行身份驗證,直到按下注銷按鈕。

爲此,我正在實施ASIHTTPRequest API以在網站上發送信息。爲驗證方法的代碼如下:

- (void)performAuthentication 
{ 
    NSURL *url = [NSURL URLWithString:@"http://mywebsite.com/index.php?option=com_community"]; 

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
    [request setDelegate:self]; 

    [request setUseKeychainPersistence:YES]; 
    [request setUseCookiePersistence:YES]; 
    [request setUseSessionPersistence:YES]; 
    [request setShouldAttemptPersistentConnection:YES]; 

    [request setRequestMethod:@"POST"]; 
    [request setUserAgent:@"Mozilla/5.0 (iPhone; CPU iPhone OS 5_0_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A405 Safari/7534.48.3"]; //does not matter, I was just trying it 
    [request setTimeOutSeconds:20]; 

    //main login options - user fills in 
    [request setPostValue:emailText.text forKey:@"username"]; 
    [request setPostValue:passwordText.text forKey:@"passwd"]; 
    [request setPostValue:@"yes" forKey:@"remember"]; 

    //secondary options derived from string 
    [request setPostValue:@"Log+in" forKey:@"submit"]; 
    [request setPostValue:@"com_user" forKey:@"option"]; 
    [request setPostValue:@"login" forKey:@"task"]; 

    [request startAsynchronous]; 
} 

- (void)requestFinished:(ASIHTTPRequest *)request 
{ 
    NSLog(@"STATUS CODE: %i", [request responseStatusCode]); 
    NSLog(@"STATUS MESSAGE: %@", [request responseStatusMessage]); 
    NSLog(@"HEADERS: %@", [request responseHeaders]); 
} 

- (void)requestFailed:(ASIHTTPRequest *)request 
{ 
    NSError *error = [request error]; 
    NSLog(@"Error = %@", error); 
} 

從requestFinished的結果是:

    "Transfer-Encoding" = Identity; 
    "X-Powered-By" = "PHP/5.2.17"; 
} 

當使用火狐與的LiveHTTPHeaders插件,我得到這個:

我m面臨3個問題:

  1. 我是獲取200個響應代碼而不是303個livehttpheaders指示。
  2. 名爲activeProfile的cookie看起來並未保存在cookie存儲中。
  3. Content-Length響應中的長標記(如livehttpheader輸出中所示)不能使用,因爲它在每次認證時都是隨機的,我不知道該如何處理它。

一般來說,身份驗證方法似乎連接但不執行該過程,剩下的就是標準http訪問的cookie。我可以通過加載一個帶有網站地址的UIWebView來驗證這一點,並且我看到用戶沒有登錄。

我不是網絡專家(儘管我可以理解某些事情)並且使用Joomla身份驗證時間。 我只是想知道如果有人遇到類似的東西,並已找到一條途徑。 任何想法或建議是非常感激。

感謝名單;)

只注意到你是不是在你的代碼中設置任何HttpHeaders。檢查你的HttpHeaders應該匹配Joomla頭。

是的,我試過。添加了所有相關的頭文件,但仍然沒有進行身份驗 – Pericles 2012-01-19 12:39:02
