401错误 - 使用AFNetworking的基本身份验证AFHTTPClient＆Tastypie

我正在使用来自AFNetworking的AFHTTPClient从我的iOS应用程序调用我的服务器，这是使用Django与TastyPie。当我在服务器端关闭身份验证时它工作得很好;然而，当我需要验证，并插入正确的用户名和密码，我的代码，我将收到下面的401身份验证错误：401错误 - 使用AFNetworking的基本身份验证AFHTTPClient＆Tastypie

AFNetworkingOperationFailingURLRequestErrorKey=<NSMutableURLRequest http://127.0.0.1:8000/api/v1/shoppinglist>}

这里是我的代码：

AFAPIClient.h ＃进口“AFHTTPClient .H”

@interface AFAPIClient : AFHTTPClient 

-(void)setUsername:(NSString *)username andPassword:(NSString *)password; 

+ (AFAPIClient *)sharedClient; 

@end

AFAPIClient.m：

#import "AFAPIClient.h" 
#import "AFJSONRequestOperation.h" 


static NSString * const baseURL = @"http://@127.0.0.1:8000/api/v1"; 


@implementation AFAPIClient 

+ (AFAPIClient *)sharedClient { 
    static AFAPIClient *_sharedClient = nil; 
    static dispatch_once_t pred; 
    dispatch_once(&pred, ^{ 
     _sharedClient = [[AFAPIClient alloc] initWithBaseURL:[NSURL URLWithString:baseURL]]; 
     //[_sharedClient setAuthorizationHeaderWithUsername:@"myusername" password:@"mypassword"]; I tried putting the authorization command here 
    }); 

    return _sharedClient; 
}; 

#pragma mark - Methods 

-(void)setUsername:(NSString *)username andPassword:(NSString *)password; 
{ 
    [self clearAuthorizationHeader]; 
    [self setAuthorizationHeaderWithUsername:username password:password]; 
} 

- (id)initWithBaseURL:(NSURL *)url 
{ 
    self = [super initWithBaseURL:url]; 
    if (!self) { 
     return nil; 
    } 

    [self registerHTTPOperationClass:[AFJSONRequestOperation class]]; 
    [self setParameterEncoding:AFJSONParameterEncoding]; 


    //[self setAuthorizationHeaderWithUsername:@"myusername" password:@"mypassword"]; I also tried putting the authorization command here 

    // Accept HTTP Header; see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1 
    [self setDefaultHeader:@"Accept" value:@"application/json"]; 

    return self; 
} 


@end

TQViewController.h：

[...] 
- (IBAction)sendAFClientRequest:(id)sender { 
    //[[AFAPIClient sharedClient] setUsername:@"myusername" andPassword:@"mypassword"]; 
    [[AFAPIClient sharedClient] getPath:@"shoppinglist" parameters:nil success:^(AFHTTPRequestOperation *operation, id response) { 
     NSLog(@"Complex AF: %@", [response valueForKeyPath:@"objects"]); 
    } failure:^(AFHTTPRequestOperation *operation, id response) { 
     NSLog(@"Complex AF: %@", response); 
    } 
    ]; 

} 
[...]

我知道这是不是我的服务器或我的用户名/密码有问题，我可以通过将用户名/密码进入URL验证就好：

@"http://myusername:[email protected]:8000/api/v1/shoppinglist"

对此的任何帮助将是伟大的。能够在不将认证信息直接插入到静态基本URL的情况下使用AFHTTPClient将是一件好事，这看起来完全不合适。提前致谢！

在此基础上：https://github.com/AFNetworking/AFNetworking/issues/426

我重写- (void)getPath:(NSString *)path parameters...方法在AFHTTPClient 子类是这个样子：

- (void)getPath:(NSString *)path parameters:(NSDictionary *)parameters 
    success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success 
    failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure 
{ 
    NSURLRequest *request = [self requestWithMethod:@"GET" path:path parameters:parameters]; 
    AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request success:success failure:failure]; 
    [operation setAuthenticationChallengeBlock:^(NSURLConnection *connection, NSURLAuthenticationChallenge *challenge) { 
     NSURLCredential *newCredential = [NSURLCredential credentialWithUser:self.username password:self.password persistence:NSURLCredentialPersistenceForSession]; 
     [challenge.sender useCredential:newCredential forAuthenticationChallenge:challenge]; 
    }]; 
    [self enqueueHTTPRequestOperation:operation]; 
}

它只会增加认证挑战块到AFHTTPRequestOpertaion，剩下的就是与原始实施相同https://github.com/AFNetworking/AFNetworking/blob/master/AFNetworking/AFHTTPClient.m
