【中文标题】AFHTTPRequestOperationManager 的 EXC_BAD_ACCESS【英文标题】:EXC_BAD_ACCESS for AFHTTPRequestOperationManager 【发布时间】:2014-07-23 04:07:58 【问题描述】:

首先调用“post 方法”,它使用 AFHTTPRequestOperationManager 工作正常。但是第二次我为同一个 AFHTTPRequestOperationManager 调用了 get 方法,得到了 EXC_BAD_ACCESS。请检查我的以下来源并帮助解决。

第一次调用“POST”方法——工作正常

NSString *post =[[NSString alloc] initWithFormat:@"grant_type=client_credentials"];

    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
                          allowLossyConversion:YES];


    NSMutableURLRequest *request = [[NSMutableURLRequest
                                     alloc] init];
    [request setURL:[NSURL URLWithString:@"https://example.com/oauth/token"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"enctype"];
    [request setValue:@"xxxxxxxxxx"] forHTTPHeaderField:@"Authorization"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"enctype"];
    [request setHTTPBody:postData];
    [request setTimeoutInterval:120];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.securityPolicy.allowInvalidCertificates = YES;
    [manager.requestSerializer setTimeoutInterval:120];
    [post release];
    AFHTTPRequestOperation *operation2 = [[AFHTTPRequestOperation alloc] init];


    operation2 = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) 
        NSLog(@"JSON: %@", responseObject);
        NSHTTPURLResponse *response = (NSHTTPURLResponse *)operation.response;
        NSLog(@"Response: %@", operation.responseString);

        NSLog(@"%ld",  (long)response.statusCode);

        NSData* data=[operation.responseString dataUsingEncoding:NSUTF8StringEncoding];

        NSString *response1 = [[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding: NSUTF8StringEncoding];

        [[NSNotificationCenter defaultCenter] postNotificationName:@"check_auth_token_init" object:[[ResponseHandler instance] parseToken:response1]];

        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];




     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
        NSLog(@"Error: %@", operation.responseString);

    ];
    [operation2 start];

第二次调用“获取”方法-EXC_BAD_ACCESS

  NSMutableURLRequest *request = [[NSMutableURLRequest
                                     alloc] init];
    [request setURL:[NSURL URLWithString:@"https://example.com/stu/groups/"]];
    [request setHTTPMethod:@"GET"];
    [request setValue:@"testing" forHTTPHeaderField:@"Authorization"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];


  //Here i tried to internalize "AFHTTPRequestOperationManager" but im getting EXC_BAD_ACCESS Please check attached screen shots

    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];



    manager.securityPolicy.allowInvalidCertificates = YES;

    // Configure Request Operation Manager
    [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];

    // Send Request
    AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) 
        NSLog(@"JSON: %@", responseObject);


     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
        NSLog(@"Error: %@", operation.responseString);

    ];
    [operation start];

【问题讨论】:

请发布堆栈跟踪。 【参考方案1】:

警告“方法可能缺少[super dealloc] 调用”表明您正在编译没有 ARC 的 AFNetworking,这可以解释为什么对象被过早地释放。

请按照 AFNetworking README 中提供的安装说明确保一切配置正确。

感谢您的回复,我会按照所有说明进行操作,然后通知您。 请帮我解决我的另一个问题***.com/questions/24948561/…
