Question

我使用AFNETWORKING 3.0向服务器发送了一个请求，其中包含以下参数：

NSString *uniqueIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; 
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];           
[parameters setObject:_texLoginUname.text forKey:@"ent_email"]; 
[parameters setObject:_textLoginPassword.text forKey:@"ent_password"];     
[parameters setObject:uniqueIdentifier forKey:@"ent_device_id"]; 
[parameters setObject:@"2" forKey:@"eat_device_type"]; 
[parameters setObject:@"22" forKey:@"ent_device_token"];

这是我的代码：

NSString *URL = @"http://optime.in/apps/food_truck/user_api/login";

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[manager POST:URL parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject)
{
    NSLog(@"success!");

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"error: %@", error);
    NSData *errorData = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
    NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData: errorData options:kNilOptions error:nil];
    NSLog(@"val = %@",serializedData);

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error while sending POST"
                                                        message:@"Sorry, try again."
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];

}];

我收到了这个错误：

NSLocalizedDescription =请求失败：未找到（404），   NSUnderlyingError = 0x7be19ef0 {错误域= com.alamofire.error.serialization.response代码= -1016＆＃34;请求失败：不可接受的内容类型：text / html＆＃34;

请帮我解决这个错误。

你应该使用以下方法，因为AFJSONRequestSerializer不起作用是AFNetworking 3.0

这个方法可以工作，因为我只使用这个方法

NSString *uniqueIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; 
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];           
[parameters setObject:_texLoginUname.text forKey:@"ent_email"]; 
[parameters setObject:_textLoginPassword.text forKey:@"ent_password"];     
[parameters setObject:uniqueIdentifier forKey:@"ent_device_id"]; 
[parameters setObject:@"2" forKey:@"eat_device_type"]; 
[parameters setObject:@"22" forKey:@"ent_device_token"]; 
NSString *URL = @"http://optime.in/apps/food_truck/user_api/login";

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:url]];
        manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];
    [manager POST:URL parameters:_parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

        NSLog(@"success!");
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"error: %@", error);
    }];

希望这件事有效
