我需要从受密码保护的 URL 解析 xml 文件，我尝试了以下操作

NSURLCredential *credential = [NSURLCredential credentialWithUser:@"admin"  password:@"123456" persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                         initWithHost:@"xyz.com"
                                         port:80
                                         protocol:@"http"
                                         realm:nil
                                         authenticationMethod:NSURLAuthenticationMethodDefault];  
[[NSURLCredentialStorage sharedCredentialStorage] setCredential:credential
                                             forProtectionSpace:protectionSpace];    
url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"GET"];
[request setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSURLResponse *response;
NSError *error;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse: &response error: &error];   
 NSString *dataStr=[[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding]; 
 NSLog(@"data == %@\n error in connecting == %@",dataStr,error);

我得到了以下响应

data == <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>401 Authorization Required</title>
</head><body>
<h1>Authorization Required</h1>
<p>This server could not verify that you
are authorized to access the document
requested.  Either you supplied the wrong
credentials (e.g., bad password), or your
browser doesn't understand how to supply
the credentials required.</p>
<p>Additionally, a 401 Authorization Required
error was encountered while trying to use an ErrorDocument to handle the request.</p>
</body></html>

连接错误 == Error Domain=NSURLErrorDomain Code=-1012 "The operation couldn't be completed. (NSURLErrorDomain error -1012.)"UserInfo=0x6e51b90 {NSErrorFailingURLKey= http://example.com/api/ID/password/xml/ ,

感谢任何帮助!

最佳答案

当使用 NSURLRequest 访问服务器时，NSURLConnection 的委托(delegate)方法提供了一种在身份验证时得到通知的方法受到挑战。

下面的示例将展示一种处理要求凭据的 URL 的方法。

- (void)CallPasswordProtectedWebService
{
 NSURL *url = [NSURL URLWithString:@"your url"];
 NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
urlConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
}

//when server asks the credentials this event will fire

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

 if ([challenge previousFailureCount] == 0) {
    NSURLCredential *newCredential;
    newCredential=[NSURLCredential credentialWithUser:@"username"                                               password:@"password"                                              persistence:NSURLCredentialPersistenceNone];
    [[challenge sender] useCredential:newCredential
           forAuthenticationChallenge:challenge];
} else {
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}
}

//when connection succeeds this event fires

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
 NSLog(@"Successfuly connected ");  

}

//when connection fails the below event fires 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
 NSLog(@"connection failed");

}
