在IOS中使用基本身份驗證的NSXMLparser

Question

我們有一個需要身份驗證來訪存XML數據的Web服務。現在我正在用swift編寫代碼來解析此XML請求。我正在使用NSXML分析器。 但它不適用於身份驗證。在哪裏傳遞這些憑據？

Answer 1

使用AFNetworking，使用AFHTTPRequestOperation你可以傳遞證書。

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 

NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:@"GET" URLString:@"http://188.40.74.207:8888/api/customer" parameters:nil error:nil]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
//[operation setCredential:credential]; 
manager.requestSerializer = [AFJSONRequestSerializer serializer]; 

[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"admin" password:@"admin"]; 
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 


    NSLog(@"Success: %@", [operation responseString]); 

} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"Failure: %@", error); 
}]; 
[manager.operationQueue addOperation:operation]; 


[manager GET:@"http://188.40.74.207:8888/api/customer" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { 
    // NSLog(@"JSON: %@", responseObject); 
    arr_Response = responseObject; 
    // NSLog(@"Arr count is: %lu", (unsigned long)arr_Response.count); 
    [SVProgressHUD dismiss]; 

    [self parseData]; 


} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}]; 

或者不使用第三方，您可以使用下面的代碼。

NSString *authStr = [NSString stringWithFormat:@"%@:%@", [self username], [self password]]; 
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding]; 
NSString *authValue = [NSString stringWithFormat:@"Basic %@",  [authData base64EncodingWithLineLength:80]]; 
[theRequest setValue:authValue forHTTPHeaderField:@"Authorization"]; 

或者你可以試試下面code.There是NSURLConnection的

// NSURLConnection Delegates 
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 
if ([challenge previousFailureCount] == 0) { 
    NSLog(@"received authentication challenge"); 
    NSURLCredential *newCredential = [NSURLCredential credentialWithUser:@"USER" 
                   password:@"PASSWORD" 
                  persistence:NSURLCredentialPersistenceForSession]; 
    NSLog(@"credential created"); 
    [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; 
    NSLog(@"responded to authentication challenge");  
} 
else { 
    NSLog(@"previous authentication failure"); 
} 
}
