如何使用Obj-C解析iPhone中的SAP業務連接器鏈接？

Question

我有在SAP瀏覽器中以XML格式打開的SAP業務連接器URL。當我在瀏覽器中粘貼SAP BU URL時，彈出窗口打開並詢問用戶ID和密碼。然後輸入密碼後顯示XML格式的數據。我知道如何解析iPhone中的XML文件，但該方法不適用於這個SAP網址。

從iPHone中使用xcode，objective C獲取用戶ID & pwd的這類url中的數據需要什麼步驟？

更新了代碼

- (void)applicationDidFinishLaunching:(UIApplication *)application { 

self.myURL = [NSURL URLWithString:@"https://connect- test.com....."]; 
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:self.myURL 
                 cachePolicy:NSURLRequestReloadIgnoringLocalCacheData 
                timeoutInterval:60]; 

[[NSURLConnection alloc] initWithRequest:request delegate:self]; 

// Configure and show the window 
[window addSubview:[navigationController view]]; 
[window makeKeyAndVisible]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge: (NSURLAuthenticationChallenge *)challenge { 

NSLog(@"received authentication challenge"); 

NSURLCredential *newCredential; 
newCredential=[NSURLCredential credentialWithUser:@"User" 
              password:@"pwd" 
             persistence:NSURLCredentialPersistenceForSession]; 

[[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; 

NSLog(@"responded to authentication challenge"); 

} 
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 
self.ZSETIK = [[NSMutableData alloc] init]; 
NSLog(@"%@ ZSETIK",ZSETIK); 

} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
[ZSETIK appendData:data]; 

} 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { 
[ZSETIK release]; 
[connection release]; 
// [textView setString:@"Unable to fetch data"]; 
} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
//NSURL *myURL = [NSURL URLWithString:@"https://connect- test.hettich.com/invoke/ZSETIK/main? vendor=su&material=100200300&purchaseorderno=4502892791"]; 

NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:self.ZSETIK]; 
//Initialize the delegate. 
XMLParser *parser = [[XMLParser alloc] initXMLParser]; 

//Set delegate 
[xmlParser setDelegate:parser]; 

//Start parsing the XML file. 
BOOL success = [xmlParser parse]; 

if(success) 
    NSLog(@"No Errors"); 
else 
    NSLog(@"Error Error Error!!!"); 

NSLog(@"Succeeded! Received %d bytes of data",[ZSETIK 
               length]); 

}

使用異步NSURLConnection的，下面NSURLConnectionDelegate將調用在這種情況下，提供用戶名和密碼，你會得到XML響應。

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 

    NSLog(@"received authentication challenge"); 

    NSURLCredential *newCredential; 
    newCredential=[NSURLCredential credentialWithUser:@"root" 
      password:@"rootpassword" 
      persistence:NSURLCredentialPersistenceForSession]; 


    NSLog(@"credential created"); 

    [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; 

    NSLog(@"responded to authentication challenge"); 

}
