我有 SAP 业务连接器 URL，它在浏览器中以 XML 格式打开。当我在浏览器中粘贴 SAP BU URL 时，弹出窗口会打开询问用户 ID 和密码。然后在输入密码后它会显示 XML 格式的数据。我知道如何在 iPhone 中解析 XML 文件，但该方法不适用于此 SAP url。

使用 xcode、objective C 从 iPHone 中具有用户 ID 和密码的此类 url 获取数据所需的步骤是什么？

用代码更新

- (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]);

}

使用异步 NSURLConnection，在这种情况下将调用 NSURLConnectionDelegate，提供用户名和密码，您将获得 xml 响应。

- (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");

}
