Ios 使用AFNetworking 2.0异常解析JSON
我在使用AFNetworking处理JSON解析数据时遇到了一个问题 这是我的密码:Ios 使用AFNetworking 2.0异常解析JSON,ios,objective-c,afnetworking-2,Ios,Objective C,Afnetworking 2,我在使用AFNetworking处理JSON解析数据时遇到了一个问题 这是我的密码: AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; NSDictionary *parameters = @{@"st
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSDictionary *parameters = @{@"strEmail": _logInEmail.text, @"strPassword":_logInPassword.text};
[manager POST:@"http://carefid.com/api/user/login.php" parameters:parameters success:^
(AFHTTPRequestOperation *operation, id responseObject) {
//NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSString *str = responseObject[@"error"];
NSLog(@"JSON: %@", str);
UIViewController *myController = [self.storyboard instantiateViewControllerWithIdentifier:@"rootController"];
[self presentViewController:myController animated:YES completion:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
当我尝试记录该值时,出现以下错误:

什么会导致这个问题?responseObject是字典吗?
如果我的代码错误,我应该如何处理?您正在将响应解析器设置为
AFHTTPResponseSerializer
,而不是AFJSONResponseSerializer
。因此,响应永远不会被解析为JSON
所以改变
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
到
正如您在评论中提到的,服务器正在交付内容text/html
,如果可能,服务器应该说内容是op-typeapplication/json
,text/json
或text/javascript
如果无法更改服务器内容类型,您可以告诉AFJSONResponseSerializer
接受text/html
如下:
AFJSONResponseSerializer *jsonReponseSerializer = [AFJSONResponseSerializer serializer];
// This will make the AFJSONResponseSerializer accept any content type
jsonReponseSerializer.acceptableContentTypes = nil;
manager.responseSerializer = jsonReponseSerializer;
2014-07-15 15:26:19.765 carefid[8036:60b]错误:错误域=com.alamofire.Error.serialization.response Code=-1016“请求失败:不可接受的内容类型:text/html”用户信息=0x10d924d10{com.alamofire.serialization.response.error.response=现在我收到了这个错误..您的服务器正在以
text/html
的形式向应用程序发送JSON内容,这是不正确的,如果可能的话,应该在服务器上更改为application/JSON
,text/JSON
或text/javascript
有任何方法可以处理它站在我这边?如果服务器现在完成了,也就是发送大约500个服务器错误页面,JSON解析将尝试并解析它。这不是一个真正的问题,只是不需要,并且以后可能会带来一些困难。值得注意的是,AFHTTPRequestOperationManager
上的默认responseSerializer
是AFJSONRes的一个实例ponseSerializer
AFJSONResponseSerializer *jsonReponseSerializer = [AFJSONResponseSerializer serializer];
// This will make the AFJSONResponseSerializer accept any content type
jsonReponseSerializer.acceptableContentTypes = nil;
manager.responseSerializer = jsonReponseSerializer;
